[PMID: 37817280 PMCID: PMC10563368 DOI: 10.1186/s13098-023-01174-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/17/2023] [Accepted: 09/27/2023] [Indexed: 10/12/2023] Open
Abstract
BACKGROUND The available evidence regarding the association of antioxidants, minerals, and vitamins with the risk of metabolic syndrome (MetS) traits is currently limited and inconsistent. Therefore, the purpose of this Mendelian randomization (MR) study was to investigate the potential causal relationship between genetically predicted antioxidants, minerals, and vitamins, and MetS. METHODS In this study, we utilized genetic variation as instrumental variable (IV) to capture exposure data related to commonly consumed dietary nutrients, including antioxidants (β-carotene, lycopene, and uric acid), minerals (copper, calcium, iron, magnesium, phosphorus, zinc, and selenium), and vitamins (folate, vitamin A, B6, B12, C, D, E, and K1). The outcomes of interest, namely MetS (n = 291,107), waist circumference (n = 462,166), hypertension (n = 463,010), fasting blood glucose (FBG) (n = 281,416), triglycerides (n = 441,016), and high-density lipoprotein cholesterol (HDL-C) (n = 403,943), were assessed using pooled data obtained from the most comprehensive genome-wide association study (GWAS) available. Finally, we applied the inverse variance weighting method as the result and conducted a sensitivity analysis for further validation. RESULTS Genetically predicted higher iron (OR = 1.070, 95% CI 1.037-1.105, P = 2.91E-05) and magnesium levels (OR = 1.130, 95% CI 1.058-1.208, P = 2.80E-04) were positively associated with increased risk of MetS. For each component of MetS, higher level of genetically predicted selenium (OR = 0.971, 95% CI 0.957-0.986, P = 1.09E-04) was negatively correlated with HDL-C levels, while vitamin K1 (OR = 1.023, 95% CI 1.012-1.033, P = 2.90E-05) was positively correlated with HDL-C levels. Moreover, genetically predicted vitamin D (OR = 0.985, 95% CI 0.978-0.992, P = 5.51E-5) had a protective effect on FBG levels. Genetically predicted iron level (OR = 1.043, 95% CI 1.022-1.064, P = 4.33E-05) had a risk effect on TG level. CONCLUSIONS Our study provides evidence that genetically predicted some specific, but not all, antioxidants, minerals, and vitamins may be causally related to the development of MetS traits.

Dong H, Hu P, Wang J, Lu N. Serum calcium and magnesium were inversely associated with high sensitivity C-reactive protein in Chinese adults with coronary artery disease. Curr Med Res Opin 2023; 39:497-503. [PMID: 36912027 DOI: 10.1080/03007995.2023.2185392] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/25/2022] [Revised: 02/14/2023] [Accepted: 02/24/2023] [Indexed: 03/14/2023]
Abstract
OBJECTIVE Scarce data examined the associations of circulating calcium (Ca) and magnesium (Mg) with high-sensitivity C-reactive protein (hsCRP) in humans. We conducted a hospital-based cross-sectional study to evaluate the associations of serum Ca, Mg, and Ca/Mg ratio with hsCRP and examine the mediating roles of body mass index (BMI). METHODS A total of 7203 patients with coronary artery disease (CAD) (average age: 61.0 years) were included. Serum concentrations of Ca, Mg, and hsCRP were measured. RESULTS The multivariate analysis of covariance was used to determine Ca- and Mg-hsCRP associations. Serum Ca and Mg were inversely associated with hsCRP, while no significant association between Ca/Mg ratio and hsCRP was detected. After adjustment for age and sex, higher Ca and Mg concentrations were associated with lower hsCRP (quintile5 [Q5] vs. Q1: 6.35 vs. 11.88 mmol/L for Ca; Q4 vs. Q1: 4.61 vs. 6.44 mmol/L for Mg). The multivariate-adjusted analysis found that serum Ca and Mg were inversely associated with hsCRP levels (Q5 vs. Q1: 6.69 vs. 11.33 mmol/L for Ca; Q4 vs. Q1: 4.65 vs. 6.32 mmol/L for Mg). Similar findings were observed in the stratified analyses by sex (men and women) and BMI (< 28 and ≥ 28 kg/m2). In path analysis, BMI had no mediating effects on the Ca- or Mg-hsCRP associations. CONCLUSION Generally, our study showed significant inverse associations of serum Ca and Mg with hsCRP in CAD patients. Our findings provided further support for the anti-inflammatory effects of Ca and Mg in CAD patients.

Abstract
BACKGROUND Findings of previous studies on relationship between dietary fiber intake and depression were inconsistent. We performed a meta-analysis on the association of dietary fiber intake with depression and anxiety in epidemiologic studies. METHODS We conducted a systematic search of electronic databases, up to May 2021. Data from 18 publications (12 cross-sectional, five cohort and one case-control studies) on dietary fiber consumption in relation to depression or anxiety were included. For depression, fifteen studies were conducted on adults and three others on adolescents. Anxiety was not included in the analysis, due to insufficient eligible studies. RESULTS Total dietary fiber intake was associated with a 10% lower odds of depression (OR = 0.90; 95% confidence interval [CI]: 0.86, 0.95) in adults and a 57% lower odds (OR = 0.43, 95% CI: 0.32, 0.59) in adolescents. Dose-response meta-analysis revealed an inverse linear association between total dietary fiber intake and odd of depression in adults; such that each 5-g increase in total dietary fiber intake was associated with a 5% reduction in risk of depression (OR = 0.95; 95% CI: 0.94, 0.97). An inverse significant association was observed between intake of fiber from vegetables (OR = 0.73; 95% CI: 0.66, 0.82) and soluble fiber (OR = 0.80, 95% CI: 0.71, 0.91) and odds of depression. However, cereal fiber, fiber from fruits and insoluble fiber were marginally associated with a reduction in having depression. CONCLUSIONS High intake of dietary fiber was protectively associated with depression in adults, in a dose-response fashion.

Evaluation among trace elements, clinical parameters and type 1 diabetes according to sex: A new sight of auxiliary prediction in negative insulin auto-antibodies population. J Trace Elem Med Biol 2023; 75:127100. [PMID: 36410305 DOI: 10.1016/j.jtemb.2022.127100] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/23/2022] [Revised: 10/13/2022] [Accepted: 11/04/2022] [Indexed: 11/10/2022]
Abstract
BACKGROUND Type 1 diabetes (T1D) exhibited sex-specific metabolic status including oxidative stress with dynamic change of trace elements, which emphasized the importance of the evaluation of trace elements according to sex. Besides, the most significant characteristic, insulin auto-antibodies, could not be found in all T1D patients, which needed the auxiliary prediction of clinical parameters. And it would benefit the early detection and treatment if some high-risk groups of T1D could predict and prevent the occurrence of disease through common clinical parameters. Hence, there was an urgent need to construct more effective and scientific statistical prediction models to serve clinic better. This study aimed to evaluate the sex-specific levels of trace elements and the relationship between trace elements and clinical parameters in T1D, and construct sex-specific auxiliary prediction model combined with trace elements and clinical parameters. METHODS A total of 105 T1D patients with negative insulin auto-antibodies and 105 age/sex-matched healthy individuals were enrolled in First Hospital of Jilin University. Inductively Coupled Plasma Mass Spectrometry was performed for the measurement of calcium (Ca), magnesium (Mg), zinc (Zn), copper (Cu), iron (Fe), selenium (Se) in the serum, and the data of clinical parameters were received from medical record system. The lambda-mu-sigma method was used to evaluate the relationship between abnormal clinical parameters and trace elements. Training set and validation set were divided for the construction of predictable models in males and females: clinical parameters model, trace element model and the combined model (clinical parameters and trace elements). Goodness fit test, decision curve analysis and other related statistical methods were used to perform data analysis. RESULTS Lower levels of Mg, Ca, Fe in the serum were found in T1D population in females compared with healthy population, while levels of Fe, Zn and Cu of serum in T1D individuals were higher than those of healthy population in males. Levels of serum Mg, Fe and Cu in T1D group were found with significant sex difference for (P < 0.05), and the levels of Fe and Cu in serum of males were higher than those of females, level of serum Mg in males was lower than those of females. Levels of serum Mg and Zn showed fluctuation trend with increased numbers of abnormal clinical parameters (NACP) in males. Serum Zn in females showed consistent elevated trend with NACP; serum Se increased first and then decreased with NACP in males and females. The auxiliary prediction model (Triglyceride, Total protein, serum Mg) was found with the highest predicted efficiency in males (AUC=0.993), while the model in females (Apolipoprotein A, Creatinine, Fe, Se, Zn/Cu ratio) showed the best predicted efficiency (AUC=0.951). The models had passed the verification in validation set, and Chi-square goodness-of-fit test, DCA results both confirmed their satisfactory clinical applicability. CONCLUSION Sex-specific difference were found in serum Mg, Fe and Cu in T1D. The combination of triglyceride, total protein and serum Mg for males, and apolipoprotein A, creatinine, Fe, Se, Zn/Cu ratio for females could effectively predict T1D in patients with negative anti-bodies, which would provide alarm for the population with high-risk of T1D and serve the T1D prediction in patients with negative anti-bodies.

Abstract
Inflammation plays an important role in the pathogenesis of many diseases, including cardiovascular diseases, atherosclerosis, diabetes, asthma, and cancer. An appropriate diet and the active compounds contained in it can affect various stages of the inflammatory process and significantly affect the course of inflammatory diseases. Recent reports indicate that polyphenolic acids, vitamins, minerals, and other components of fruits may exhibit activity stimulating an anti-inflammatory response, which may be of importance in maintaining health and reducing the risk of disease. The article presents the latest data on the chemical composition of fruits and the health benefits arising from their anti-inflammatory and antioxidant effects. The chemical composition of fruits determines their anti-inflammatory and antioxidant properties, but the mechanisms of action are not fully understood.

Abstract
Metabolic syndrome (MetS) is increasingly prevalent, and the relationship between dietary magnesium and MetS remains controversial. Therefore, we aimed to explore the association and dose-response relationship between dietary magnesium intake and MetS and its single component. The sample was adults aged 18 years and above who participated in at least two follow-up surveys in 2009, 2015 and 2018. Food consumption data were collected from three consecutive 24-h dietary recalls. The multivariate Cox proportional risk regression model and restricted cubic spline (RCS) model were used to analyze the association and dose-response relationship between dietary magnesium intake and MetS and its components. In our study, 6104 subjects were included, with a total follow-up of 37,173.36 person-years, and the incidence was 33.16%. Cox regression analysis showed that the multivariable-adjusted Hazard Ratio (HR) for MetS comparing the highest to the lowest quintile of dietary magnesium intake was 0.84 (95% confidence intervals [CI] = 0.71-0.99). Central obesity, elevated TG, elevated blood pressure and elevated blood glucose were reduced by 18%, 41%, 20% and 42%, respectively. The risk of decreased HDL-C was reduced by 23% in the third quintile of dietary magnesium intake, with a slightly increased risk in the highest group. RCS analysis showed that the overall and non-linear associations between dietary magnesium and MetS and its components were statistically significant, the risk of them decreased significantly when magnesium intake was lower than 280 mg/day, and then the curve leveled off or slightly increased.

Abstract
Magnesium (Mg) is an essential nutrient for maintaining vital physiological functions. It is involved in many fundamental processes, and Mg deficiency is often correlated with negative health outcomes. On the one hand, most western civilizations consume less than the recommended daily allowance of Mg. On the other hand, a growing body of evidence has indicated that chronic hypomagnesemia may be implicated in the pathogenesis of various metabolic disorders such as overweight and obesity, insulin resistance (IR) and type 2 diabetes mellitus (T2DM), hypertension (HTN), changes in lipid metabolism, and low-grade inflammation. High Mg intake with diet and/or supplementation seems to prevent chronic metabolic complications. The protective action of Mg may include limiting the adipose tissue accumulation, improving glucose and insulin metabolism, enhancing endothelium-dependent vasodilation, normalizing lipid profile, and attenuating inflammatory processes. Thus, it currently seems that Mg plays an important role in developing metabolic disorders associated with obesity, although more randomized controlled trials (RCTs) evaluating Mg supplementation strategies are needed. This work represents a review and synthesis of recent data on the role of Mg in the pathogenesis of metabolic disorders.

Abstract
BACKGROUND Intake time of diet has recently been demonstrated to be associated with the internal clock and circadian pattern. However, whether and how the intake time of minerals would influence the natural course of cancer was largely unknown. METHODS This study aimed to assess the association of mineral intake at different periods with cancer and all-cause mortality. A total of 27,455 participants aged 18-85 years old in the National Health and Nutrition Examination Survey were recruited. The main exposures were the mineral intakes in the morning, afternoon and evening, which were categorized into quintiles, respectively. The main outcomes were mortality of cancer and all causes. RESULTS During the 178,182 person-years of follow-up, 2680 deaths, including 601 deaths due to cancer, were documented. After adjusting for potential confounders, compared to the participants who were in the lowest quintile(quintile-1) of mineral intakes at dinner, the participants in the highest quintile intake(quintile-5) of dietary potassium, calcium and magnesium had lower mortality risks of cancer (HRpotassium = 0.72, 95% CI:0.55-0.94, P for trend = 0.023; HRcalcium = 0.74, 95% CI:0.57-0.98, P for trend = 0.05; HRmagnesium = 0.75, 95% CI:0.56-0.99, P for trend = 0.037) and all-cause (HRpotassium = 0.83, 95% CI:0.73-0.94, P for trend = 0.012; HRcalcium = 0.87, 95% CI:0.76-0.99, P for trend = 0.025; HRmagnesium = 0.85, 95% CI:0.74-0.97, P for trend = 0.011; HRcopper = 0.80, 95%CI: 0.68-0.94, P for trend = 0.012). Further, equivalently replacing 10% of dietary potassium, calcium and magnesium consumed in the morning with those in the evening were associated with lower mortality risk of cancer (HRpotassium = 0.94, 95%CI:0.91-0.97; HRcalcium = 0.95, 95%CI:0.92-0.98; HRmagnesium = 0.95, 95%CI: 0.92-0.98). CONCLUSIONS This study demonstrated that the optimal intake time of potassium, calcium and magnesium for reducing the risk of cancer and all-cause mortality was in the evening.

In this study, 83 healthy middle-aged women (40-55 years) with vitamin D deficiency were randomly assigned into two groups: (1) intervention: receiving a 50,000-IU vitamin D soft gel (weekly) plus a 250-mg magnesium tablet (daily); (2) control: receiving a vitamin D placebo (weekly) plus a magnesium placebo (daily), for 8 weeks. Before and after the intervention, anthropometric indices, muscle strength, muscle function, and some inflammatory markers were measured. After 8 weeks of supplementation, significant difference was observed in handgrip strength and time for Time Get Up and Go (TGUG) test between the intervention and placebo groups (P < 0.05). Regarding percentage of fat mass (FM%) and fat free mass (FFM%), and knee extension strength, there was no significant difference between the two groups at the end of intervention (P > .05). Serum 25(OH)-D levels increased significantly (P < 0.001) and its change was significantly different between the two groups, at the end of the intervention (P < 0.001). Serum level of hs-CRP decreased significantly in the intervention group compared to baseline (P < 0.001), and the change in hs-CRP was significant between the two groups at the end of the intervention (P < 0.01). Furthermore, serum level of TNF-α declined significantly in the intervention group compared to baseline (P < 0.001) but, no significant differences were seen between the two groups in regard of serum levels of TNF-α and IL-6 after the intervention (P > 0.05). Our findings show that vitamin D and magnesium co-supplementation, for 8 weeks, in healthy middle-aged women with vitamin D deficiency have beneficial impacts on muscle strength, muscle function, and probably inflammation.

Abstract
This cross-sectional study aimed to examine the associations between dietary fibre (DF) intake and depressive symptoms in a general adult population in Tianjin, China. A total of 24 306 participants (mean age 41 years; range 18-91 years) were enrolled. DF intake was assessed using a validated self-administered FFQ. Depressive symptoms were assessed using the Self-Rating Depression Scale. Associations between DF intake and depressive symptoms were estimated using logistic regression analysis. Socio-demographic, behavioural, health status and dietary factors were adjusted. In men, compared with participants in the lowest quartiles for total, soluble, vegetable and soya DF, OR for depressive symptoms in the highest were 0·83 (95 % CI 0·69, 0·99), 0·74 (95 % CI 0·63, 0·87), 0·79 (95 % CI 0·65, 0·96) and 0·69 (95 % CI 0·60, 0·81), respectively. In women, compared with participants in the lowest quartiles for vegetable and soya DF, the OR for depressive symptoms in the highest were 0·77 (95 % CI 0·64, 0·93) and 0·82 (95 % CI 0·70, 0·95), respectively. No association was found between total or soluble DF intake and depressive symptoms in women. No association was found between insoluble, cereal, fruit or tuber DF intake and depressive symptoms in men and women. Linear associations between DF intake and depressive symptoms were only detected for soya DF (men, β = -0·148, P < 0·0001; women, β = -0·069, P = 0·04). Results suggest that intake of soluble, vegetable and soya DF was inversely associated with depressive symptoms. These results should be confirmed through prospective and interventional studies.

Abstract
Osteoarthritis (OA) is a prevalent debilitating age-related skeletal disease. The hallmark of OA is the degradation of articular cartilage that cushions the joint during movement. It is characterized by chronic pain and disability. Magnesium, a critical trace element in the human body, plays a pivotal role in metabolism homeostasis and the energy balance. Humans obtain magnesium mainly from the diet. However, inadequate magnesium intake is not uncommon. Moreover, the magnesium status deteriorates with ageing. There has been a growing body of clinical studies pointing to an intimate relationship between dietary magnesium and OA although the conclusion remains controversial. As reported, the magnesium ion concentration is essential to determine cell fate. Firstly, the low-concentration magnesium ions induced human fibroblasts senescence. Magnesium supplementation was also able to mitigate chondrocyte apoptosis, and to facilitate chondrocyte proliferation and differentiation. In this literature review, we will outline the existing evidence in animals and humans. We will also discuss the controversies on plasma or intracellular level of magnesium as the indicator of magnesium status. In addition, we put forward the interplay between dietary magnesium intake and intestinal microbiome to modulate the inflammatory milieu in the conjecture of OA pathogenesis. This leads to an emerging hypothesis that the synergistic effect of magnesium and probiotics may open a new avenue for the prevention and treatment of OA.

Low Dietary Magnesium and Overweight/Obesity in a Mediterranean Population: A Detrimental Synergy for the Development of Hypertension. The SUN Project. Nutrients 2020; 13:nu13010125.

Abstract
Hypertension is the strongest independent modifiable risk factor for cardiovascular disease. We aimed to investigate the association of magnesium intake with incident hypertension in a Mediterranean population, and the potential modification of this association by body mass index BMI. We assessed 14,057 participants of the SUN (Seguimiento Universidad de Navarra) prospective cohort (67.0% women) initially free of hypertension. At baseline, a validated 136-item food frequency questionnaire was administered. We used Cox models adjusted for multiple socio-demographic, anthropometric, and lifestyle factors, and prevalent conditions present at baseline. Among a mean 9.6 years of follow-up we observed 1406 incident cases of medically diagnosed hypertension. An inverse association in multivariable-adjusted models was observed for progressively higher magnesium intake up to 500 mg/d vs. intake < 200 mg/d, which was greater among those with a BMI > 27 kg/m2. Lean participants with magnesium intake < 200 mg/d vs. >200 mg/d also had a higher risk of incident hypertension. Adherence to the Mediterranean diet did not modify these associations. In conclusion, dietary magnesium intake < 200 mg/d was independently associated with a higher risk of developing hypertension in a Mediterranean cohort, stronger for overweight/obese participants. Our results emphasize the importance of encouraging the consumption of magnesium-rich foods (vegetables, nuts, whole cereals, legumes) in order to prevent hypertension.

Abstract
Hypomagnesemia is commonly observed in heart failure, diabetes mellitus, hypertension, and cardiovascular diseases. Low serum magnesium (Mg) is a predictor for cardiovascular and all-cause mortality and treating Mg deficiency may help prevent cardiovascular disease. In this review, we discuss the possible mechanisms by which Mg deficiency plays detrimental roles in cardiovascular diseases and review the results of clinical trials of Mg supplementation for heart failure, arrhythmias and other cardiovascular diseases.

Abstract
Objective Inflammation plays a leading role in the pathogenesis of nephrolithiasis. The association of the dietary inflammatory index (DII) with urinary lithogenic factors is unclear. This study aimed to evaluate the relation of DII to urinary risk factors of kidney stones formation. Results Of 264 participants, 61.4% (n = 162), 72% (n = 190), 74.6% (n = 197), 68.6% (n = 181), and 80.3% (n = 212) had hyperoxaluria, hypercreatininuria, hypercalciuria, hyperuricosuria, hypocitraturia, respectively. There was a significant increasing trajectory in urinary calcium, uric acid, and creatinine as well as a decreasing trend in urinary citrate across tertiles of DII score (all P = ≤0.001). After multivariate adjustment for energy intake, age, physical activity and body mass index, high DII scores were associated with elevated odds of having hypercreatininuria (OR = 2.80, 95%CI: 1.10–7.12, Ptrend = 0.04), hypercalciuria (OR = 7.44, 95%CI: 2.62–21.14, Ptrend ≤ 0.001), hyperuricosuria (OR = 2.22, 95%CI: 1.001–4.95, Ptrend = 0.05), and hypocitraturia (OR = 5.84, 95%CI: 2.14–15.91, Ptrend ≤ 0.001). No association was identified between DII and hyperoxaluria.

Abstract
Dietary fiber is a crucial component of a healthy diet, with benefits that can be attributed to processes in the gut microbiota and the resulting by-products. Observational studies support associations between dietary fiber intake and depression and inflammation, but the potential mechanisms are poorly understood. This review examines evidence of the effects of dietary fiber on depression and inflammation and considers plausible mechanisms linking dietary fiber and depression, including microbiota-driven modification of gene expression and increased production of neurotransmitters. Additionally, inflammation may mediate the relationship between dietary fiber intake and depression. A high-fiber diet potentially lowers inflammation by modifying both the pH and the permeability of the gut. The resultant reduction in inflammatory compounds may alter neurotransmitter concentrations to reduce symptoms of depression. Further research into the link between dietary fiber intake and inflammation and depression is essential, as findings could potentially provide guidance for improvement in or prevention of inflammatory and depressive disorders.

Abstract
A high dietary fibre intake has been associated with improvements in inflammatory conditions in adults. However, little is known on whether associations between dietary fibre and inflammation are evident during adolescence. We examined the relationship between dietary fibre intake measured by FFQ and the inflammatory marker high-sensitivity C-reactive protein (hs-CRP) and the adipokines leptin and adiponectin cross-sectionally in 17-year-olds participating in the Raine Study (n 621). In weighted analysis using tobit and linear regression, and after excluding participants with hs-CRP > 10 mg/l, higher total dietary fibre intake (per 5 g/d) was significantly associated with lower leptin (β = -0·13, 95 % CI -0·17, -0·09) and adiponectin (β = -0·28, 95 % CI -0·49, -0·07), but not hs-CRP, in unadjusted analyses. These associations were no longer significant after adjustment for sex, anthropometry and a number of lifestyle factors. However, higher cereal and grain fibre intake was significantly associated with lower leptin (β = -0·06, 95 % CI -0·10, -0·01) in fully adjusted analysis. Our findings suggest that a higher intake of cereal and grain fibre may contribute to lower leptin in adolescents. This may contribute to reductions in low-grade chronic inflammation and improved health outcomes.

Abstract
BACKGROUND Globalization has lead to such lifestyle changes which have produced increase in incidence and prevalence of Type 2 Diabetes Mellitus (T2DM). Magnesium is found to have some role in glucose metabolism. The aim of this study was to investigate the relationship between serum magnesium levels with insulin resistance in apparently healthy adults. OBJECTIVE The objective of our study was to evaluate correlation of serum magnesium with fasting blood sugar, insulin level and Homeostasis model assessment-insulin resistance (HOMA-IR) index (indicator of insulin resistance) on the basis of the hypothesis that subjects with hypomagnesaemia are more prone to develop hyperglycemia and insulin resistance. MATERIALS AND METHODS The study was a cross-sectional study which was population based. Total 130 apparently healthy adults of age between 25-65 years, were recruited with prior ethical approval and written informed consent. RESULTS Serum magnesium was found to be negatively correlated with fasting blood sugar (FBS), insulin level and HOMA-IR. Co-relation of magnesium with FBS (r = -0.55, p<0.0001), insulin (r = -0.45, p< 0.0001) and HOMA-IR (r = -0.52, p<0.0001) was significant. CONCLUSION As per findings it was concluded that serum magnesium was found to have significant negative correlation with fasting blood sugar (FBS), insulin and HOMA-IR, thus hypomagnesaemia can be suggested to be one of the important predictor of type 2 diabetes mellitus.

Abstract
PURPOSE The aim of this study was to investigate the association between dietary inflammatory index (DII) and metabolic syndrome (MetS) and its components using data of Ravansar non-communicable diseases (RaNCD) cohort study. PATIENTS AND METHODS The present cross-sectional study was performed using the information of 6538 participants in the RaNCD study in Iran. A validated 125-item food frequency questionnaire (FFQ) was used to acquire DII scores. MetS was defined based on national cholesterol education program-adult treatment panel III (NCEP-ATP III) criteria. The association between DII and MetS and its components was investigated by the logistic regression model using STATA software. RESULTS A significant association was found between DII and MetS (OR trend: 1.08, 95% CI: 1.01-1.15, P =0.017), triglyceride (TG) (OR trend: 1.06, 95% CI: 1.00-1.12, P=0.030), fasting blood glucose (FBG) (OR trend: 1.10, 95% CI: 1.01-1.20, P=0.018) and high density lipoprotein cholesterol (HDL-C) (OR trend: 1.07, 95% CI: 1.02-1.12, P= 0.005) after adjustment for all covariates. Also, there was a significant relationship between DII score and waist circumference (WC) (OR trend: 1.07, 95% CI: 1.01-1.14, P=0.016). CONCLUSION Higher DII score (a pro-inflammatory diet) had a significant association with the risk of MetS and its components, even after adjustment for different potential confounding factors including socio-demographic data and lifestyle habits. However, further longitudinal investigations with more dietary parameters are needed to elucidate the role of the pro-inflammatory diet in the etiology of MetS.

Abstract
AIM We aimed to examine the association between serum magnesium and diabetes and hypertension among Qatari adults. METHODS In the cross-sectional study, we used data from 9693 Qatari participants aged 20 years and above attending the Qatar Biobank (QBB) Study. Blood samples were analyzed in a central lab. Habitual food consumption was assessed by a food frequency questionnaire. Reduced rank regression was used to construct magnesium related dietary pattern (MRDP) using serum magnesium as a response variable. Diabetes was defined by blood glucose, HbA1c or known diabetes. Prediabetes was defined as HbA1c between 5.7% and 6.4%. Subclinical magnesium deficiency was defined as serum magnesium <0.85 mmol/L. RESULTS The prevalence of diabetes, prediabetes and subclinical magnesium deficiency was 18.9%, 11.5% and 59.5%, respectively. Across the quartiles of serum magnesium from high to low, the prevalence ratios (PR 95%CI) for diabetes were 1.00, 1.35, 1.88, and 2.70 (95%CI 2.38-3.05), respectively (p for trend <0.001). The presence of hypertension significantly increased the probability of diabetes along a wide range of low serum magnesium. A low intake of MRDP was also positively associated with diabetes and high HbA1c. CONCLUSION Subclinical magnesium deficiency is common in Qatar and associates with diabetes, prediabetes and hypertension in Qatari adults.

Abstract
BACKGROUND Women with polycystic ovary syndrome (PCOS) often have insulin resistance (IR) which may be worsened by obesity. The roles of dietary intake and activity are unclear. Our objectives were to determine whether (a) high caloric intake or inactivity explains obesity in PCOS, and (b) dietary composition is associated with PCOS phenotypes. METHODS Eighty-seven women with PCOS and 50 women without PCOS participated in this cohort study at a reproductive medicine center. Data collected included 3-day food and physical activity records, anthropometrics, and metabolic and hormonal assays. RESULTS Women with PCOS had increased body mass index (BMI) but similar caloric intake and activity to women without PCOS. There were no differences in protein, carbohydrates, fat, or glycemic load consumption, but women with PCOS consumed less fiber (medians: 19.6 vs. 24.7 g) and less magnesium (medians: 238.9 vs. 273.9 mg). In women with PCOS, those with IR consumed less fiber, less magnesium, and greater glycemic load than those without IR (medians: 18.2 vs. 22.1 g, 208.4 vs. 264.5 mg, 89.6 vs. 83.5). Fiber intake of women with PCOS was negatively correlated with IR, fasting insulin, glucose tolerance, testosterone, and dehydroepiandrosterone sulfate. Magnesium intake was negatively correlated with IR, C-reactive protein, and testosterone, but positively correlated with HDL cholesterol. Fiber intake and BMI accounted for 54.0% of the variance observed in IR. CONCLUSIONS Obesity in women with PCOS could not be explained by overeating or inactivity. Increasing dietary fiber and magnesium intakes may assist in reducing IR and hyperandrogenemia in women with PCOS.

Abstract
Background: Non-Alcoholic Fatty Liver Disease (NAFLD) is considered as a major health problem in the world. There is much evidence that diet and dietary factors play an important role in inflammation, and consequently pathogenesis of NAFLD. To investigate the role of diet in the development of inflammation, we can use the Dietary Inflammatory Index (DII), which has been shown to be predictive of levels of inflammatory markers. Methods: 295 incident cases were selected using the convenience-sampling procedure, and 704 controls randomly were selected from the same clinic and among the patients who had no hepatic steatosis and were frequency-matched on age (±5 years) and sex. The DII was computed based on dietary intake from 168-item FFQ. Logistic regression models were used to estimate multivariable ORs. Results: Subjects in tertile 3 had 1.57 (95% CI: 1.13-2.20), 1.78 (95% CI: 1.19-2.67), and 2.02 (95% CI: 1.32-3.09) times higher odds of developing NAFLD, compared to subjects in tertile 1 in models 1 (adjusted for age), 2 (model 1 + BMI, education, smoking, alcohol, diabetes, low density lipoprotein, triglycerides) and 3 (model 2 + aspartate transaminase/alanine transaminase), respectively. When used as a continuous variable, one unit increase in DII was associated with 1.16 (95% CI: 1.05, 1.29), 1.21 (95% CI: 1.107, 1.37) and 1.25 (95% CI: 1.10, 1.43) increase in odds of NAFLD in models one, 2 and 3 respectively. Conclusion: Subjects who consumed a more pro-inflammatory diet were at increased odds of NAFLD.

Abstract
BACKGROUND While evidence exists for an association between the dietary inflammatory index (DII) and cardiovascular diseases, the relation between DII and chronic kidney disease (CKD) is not known. OBJECTIVE To examine the association between DII, renal function and progression of CKD. METHODS In this cross-sectional study, dietary data from 221 subjects with diagnosed CKD were collected using a validated food frequency questionnaire. DII was calculated based on overall inflammatory effect scores. Renal function was measured by blood urea nitrogen (BUN) and serum creatinine (Cr) level as well as estimated glomerular filtration rate (eGFR). RESULTS Patients in the first tertile of DII consumed higher quantities of vegetables, fruits, dairy, calcium, potassium and phosphorus and lower amounts of grains (P < 0.01 for all). We did not detect any significant trend for BUN, Cr and eGFR across tertiles of DII in crude and two adjusted models. In a fully adjusted model, an increased risk of being in the higher stage of CKD was found among those in the top tertiles of DII (odds ratio: 2.12; 95% CI: 1.05, 4.26; P for trend = 0.03). CONCLUSION We observed that compliance with a pro-inflammatory diet in patients with CKD may be associated with disease progression.

Abstract
Background and Aims: C-reactive protein (CRP) is commonly used as a biomarker for inflammation. Mild elevations of CRP have been seen in chronic autoimmune diseases like systemic lupus erythematosus (SLE), and CRP has been linked to an increased risk of cardiovascular events. Diet quality and certain dietary factors seem to influence CRP levels in healthy subjects. To date, the effect of diet on serum CRP in SLE has not been studied. Our aim was to investigate the relationship between dietary nutrients, antioxidant intake, and serum CRP in SLE. Design and Method: A cross-sectional study was conducted among 91 patients with SLE. High-sensitivity hsCRP values were determined using an immuno-turbidimetry assay in a Beckman Coulter analyzer (AU5800). Dietary intake of macro- and micronutrients was assessed through a 24-hr diet recall. Antioxidant nutrient intake was evaluated using the dietary antioxidant quality score (DAQs). Linear regression models were used to investigate the relationships between serum hsCRP levels, dietary nutrient intake, and DAQs. Results: The mean serum hsCRP level observed (3.76 ± 6.68 mg/L) was above the established normal range. However, participating SLE patients had low-quality diets, and we found no significant correlations between dietary intake of macro- or micronutrients or antioxidant nutrient intake (DAQs) and serum CRP levels. Conclusion: Our study reveals that participating SLE patients had a low-quality diet that did not influence inflammatory status measured using serum CRP levels. Further interventional studies with high-quality diets in this population are necessary to dissect the role of diet on CRP levels in SLE.

Abstract
OBJECTIVES To examine the associations between serum magnesium (Mg) concentration with the prevalence of metabolic syndrome (MetS), diabetes mellitus (DM), hypertension (HP) and hyperuricaemia (HU) in patients with radiographic knee osteoarthritis (OA). METHODS The present study was conducted at the Health Management Center of Xiangya Hospital. Radiographic OA was evaluated for patients aged over 40 years with basic characteristics and blood biochemical assessment. Serum Mg concentration was measured using the chemiluminescence method. MetS, DM, HP and HU were diagnosed based on standard protocols. The associations between serum Mg concentration with MetS, DM, HP and HU were evaluated by conducting multivariable adjusted logistic regression. RESULTS A total of 962 patients with radiographic knee OA were included. Compared with the lowest quintile, the multivariable adjusted ORs and related 95% CIs of DM were 0.40 (95% CI 0.23 to 0.70, p=0.001), 0.33 (95% CI 0.18 to 0.60, p<0.001), 0.27 (95% CI 0.14 to 0.52, p<0.001) and 0.22 (95% CI 0.11 to 0.44, p<0.001) in the second, third, fourth and highest quintiles of serum Mg, respectively (p for trend <0.001); the multivariable adjusted ORs of HU were 0.33 (95% CI 0.19 to 0.59, p<0.001), 0.52 (95% CI 0.30 to 0.91, p=0.022) and 0.39 (95% CI 0.22 to 0.70, p=0.001) in the third, fourth and highest quintiles of serum Mg, respectively (p for trend <0.001); and the multivariable adjusted ORs of MetS were 0.59 (95% CI 0.36 to 0.94, p=0.027) in the second and 0.56 (95% CI 0.34 to 0.93, p=0.024) in the highest quintiles of serum Mg. However, the inverse association between serum Mg and the prevalence of MetS was non-linear (p for trend=0.067). There was no significant association between serum Mg and HP in patients with OA. CONCLUSIONS The serum Mg concentration was inversely associated with the prevalence of MetS, DM and HU in patients with radiographic knee OA. LEVEL OF EVIDENCE Level III, cross-sectional study.

Abstract
UNLABELLED Magnesium and zinc are known to exert multiple beneficial effects including anti-inflammatory and antioxidant actions. To our knowledge, data on the effects of magnesium and zinc co-supplementation on biomarkers of inflammation and oxidative stress and gene expression related to inflammation in subjects of polycystic ovary syndrome (PCOS) are scarce. This study was conducted to evaluate the effects of magnesium and zinc co-supplementation on biomarkers of inflammation and oxidative stress and gene expression related to inflammation in subjects with PCOS. This randomized double-blind, placebo-controlled trial was conducted among 60 subjects with PCOS diagnosed according to the Rotterdam criteria, aged 18-40 years old. Participants were randomly assigned into two groups to take either 250 mg of magnesium oxide plus 220 mg of zinc sulfate (containing 50 mg zinc) supplements (n = 30) or placebo (n = 30) twice a day for 12 weeks. Biomarkers of inflammation and oxidative stress were assessed at baseline and at end of treatment. Gene expression related to inflammatory cytokines was assessed in peripheral blood mononuclear cells (PBMCs) of PCOS women with RT-PCR method. After the 12-week intervention, compared with the placebo, magnesium and zinc co-supplementation significantly decreased serum high-sensitivity C-reactive protein (hs-CRP) (- 1.6 ± 2.4 vs. + 0.1 ± 0.7 mg/L, P = 0.001) and protein carbonyl (PCO) (- 0.14 ± 0.28 vs. + 0.02 ± 0.07 mmol/mg protein, P = 0.002) and significantly increased plasma total antioxidant capacity (TAC) levels (+ 60.7 ± 69.4 vs. - 1.5 ± 141.5 mmol/L, P = 0.03). Results of RT-PCR demonstrated that compared with the placebo, magnesium and zinc co-supplementation downregulated gene expression of interleukin-1 (IL-1) (P = 0.007) and tumor necrosis factor alpha (TNF-α) (P = 0.03) in PBMCs of subjects with PCOS. Overall, magnesium and zinc co-supplementation, compared with the placebo, for 12 weeks among PCOS women had beneficial effects on serum hs-CRP, plasma PCO, TAC, and gene expression of IL-1 and TNF-α.

Abstract
OBJECTIVES Magnesium may play an important role in the prevention or treatment of epilepsy. We aimed to examine the association between dietary intake of magnesium and the incidence of epilepsy in middle-aged Finnish men in a prospective setting. As a secondary analysis, we also considered a possible association between dietary intake of magnesium and inflammation in subjects with epilepsy. METHODS The study included 2442 men, ages 42 to 60 y, from the prospective Kuopio Ischaemic Heart Disease Risk Factor Study who were free of epilepsy at baseline between 1984 and 1989. Dietary intake of magnesium was assessed with a 4-d food record. The hospital discharge diagnosis of epilepsy was used as an outcome variable. RESULTS During the average follow-up period of 22.4 y, 74 men (3%) developed epilepsy. Those who followed the recommended dietary intake (>350 mg/d) of magnesium had a lower risk of epilepsy (hazard ratio [HR]: 0.52; confidence interval [CI], 0.28-0.99; P = 0.045) after multivariate adjustments. However, the risk was not significant after adjustment for C-reactive protein (CRP). We also found that CRP concentration was directly associated with the risk of epilepsy (HR: 1.24; CI, 1.00-1.54; P = 0.048). This association was attenuated after adjustment for dietary intake of magnesium and no longer significantly associated with the risk of epilepsy (HR: 1.22; CI, 0.99-1.52; P = 0.07). CONCLUSIONS A higher dietary intake of magnesium was associated with lower incident epilepsy, and this association was slightly mediated by CRP. Further studies are required to identify the potential mechanisms.

Abstract
Background: Gastric cancer (GC) is the fifth most common malignancy and the second leading cause of cancer-related deaths worldwide. Studies have shown that dietary components and inflammation are implicated in the etiology of GC. Methods: We examined the ability of a dietary inflammatory index (DII) to predict the odds of GC in a case-control study conducted from December 2014 to May 2016. The subjects were 82 cases and 95 controls who attended specialized centers in Tabriz, Iran. DII scores were computed from a validated 168-item food frequency questionnaire. Logistic regression models were used to estimate odds ratios (ORs) adjusted for age, sex, body mass index, education, smoking, alcohol, H.pylori infection, physical activity, aspirin/NSAID use and total caloric intake. Results: In the fully adjusted model, subjects with a DII score >-1.77 had nearly 3.5 times higher odds of having GC compared with subjects with DII≤-1.77, (ORDII>-1.77≤-1.77=3.39; 95%CI=1.59, 7.22). Also, for every one-unit increase in DII, there was a corresponding increase in hs-C-reactive protein, tumor necrosis factor-alpha, interleukin (IL)-6 and IL-1b: β=0.09, 0.16, 0.16 and 0.10, respectively; and a corresponding decrease in IL-10: β=-0.11. Conclusion: Subjects who consumed a more pro-inflammatory diet were at increased odds of GC compared to those who consumed a more anti-inflammatory diet.

Abstract
Background: Breast cancer (BrCa) is the most common cancer among women worldwide and is the second leading cause of cancer-related death in women, in developed countries. This cancer is among the top five most common cancers in Iran. Studies have shown that dietary components are implicated in the etiology of BrCa. The existence of molecular connections between inflammation and BrCa has been demonstrated via different bimolecular events. Methods: We examined the ability of the dietary inflammatory index (DIITM) to predict the risk of BrCa. This included 145 cases and 148 controls, who attended the specialized centers. DII scores were computed based on dietary intake assessed using a 168-item FFQ. Logistic regression models were used to estimate multivariable ORs. Results: Modeling DII as a continuous variable in relation to risk of BrCa showed a positive association after adjustment for age and energy (OR=1.76; 95% CI=1.43-2.18); and were nearly identical in the multivariable analyses (OR=1.80; 95% CI=1.42-2.28). DII as tertiles, and adjusting for age and energy, subjects in tertile 3 had an OR of 6.94 (95% CI= 3.26-14.79; P-trend ≤0.0001) in comparison to subjects in tertile 1. After multivariable adjustment, results were essentially identical as in the model adjusting for age and energy (OR tertile 3vs1=7.24; 95% CI=3.14-16.68; P-trend ≤0.001). Sub group analyses revealed similar positive associations with HER 2 receptor +ve, progesterone receptor +ve, estrogen receptor +ve and lymph node invasive cases. Conclusion: Subjects who consumed a more pro-inflammatory diet were at increased risk of BrCa compared to those who consumed a more anti-inflammatory diet.

Abstract
Although official magnesium (Mg) dietary reference intakes are open to question, a significant number of adults likely have intakes that are in the range of 50%-99% of the requirement. This moderate or marginal (subclinical) deficient Mg intake generally is asymptomatic. Animal studies, however, indicate that moderate or subclinical Mg deficiency primes phagocytic cells for the release of proinflammatory cytokines leading to chronic inflammatory and oxidative stress. Human studies have found that dietary Mg is inversely related to serum or plasma C-reactive protein (CRP). Individuals with apparently deficient Mg intakes have an increased likelihood of serum or plasma CRP ≥3.0 mg/L, considered an indicator of chronic inflammatory stress that increases the risk for chronic disease. In addition, elevated serum or plasma CRP in individuals with chronic disease is decreased by Mg supplementation, which suggests that Mg decreases the risk for chronic disease. The importance of dietary Mg intake on the risk for chronic disease through affecting inflammatory and oxidative stress is supported by numerous meta-analyses and systematic reviews that have found dietary Mg is inversely associated with chronic diseases such hypertension, ischemic heart disease, stroke, metabolic syndrome, diabetes, and colorectal cancer.

Low magnesium intake is associated with increased knee pain in subjects with radiographic knee osteoarthritis: data from the Osteoarthritis Initiative. Osteoarthritis Cartilage 2018; 26:651-658. [PMID: 29454594 DOI: 10.1016/j.joca.2018.02.002] [Citation(s) in RCA: 28] [Impact Index Per Article: 4.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/02/2017] [Revised: 02/04/2018] [Accepted: 02/07/2018] [Indexed: 02/02/2023]
Abstract
OBJECTIVE As magnesium mediates bone and muscle metabolism, inflammation, and pain signaling, we aimed to evaluate whether magnesium intake is associated with knee pain and function in radiographic knee osteoarthritis (OA). METHODS We investigated the associations between knee pain/function metrics and magnesium intake from food and supplements in 2548 Osteoarthritis Initiative cohort participants with prevalent radiographic knee OA (Kellgren-Lawrence score ≥2). Magnesium intake was assessed by Food Frequency Questionnaire (FFQ) at baseline. WOMAC and Knee Injury and Osteoarthritis Outcome Score (KOOS) scores were reported annually with total follow up of 48 months. Analyses used linear mixed models. RESULTS Among participants with baseline radiographic knee OA the mean total magnesium intake was 309.9 mg/day (SD 132.6) for men, and 287.9 mg/day (SD 118.1) for women, with 68% of men and 44% of women below the estimated average requirement. Subjects with lower magnesium intake had worse knee OA pain and function scores, throughout the 48 months (P < 0.001). After adjustment for age, sex, race, body mass index (BMI), calorie intake, fiber intake, pain medication use, physical activity, renal insufficiency, smoking, and alcohol use, lower magnesium intake remained associated with worse pain and function outcomes (1.4 points higher WOMAC and 1.5 points lower KOOS scores for every 50 mg of daily magnesium intake, P < 0.05). Fiber intake was an effect modifier (P for interaction <0.05). The association between magnesium intake and knee pain and function scores was strongest among subjects with low fiber intake. CONCLUSION Lower magnesium intake was associated with worse pain and function in knee OA, especially among individuals with low fiber intake.

Abstract
BACKGROUND AND AIM Growing evidence suggests that some of the effects of diet on cardiovascular disease (CVD) occur through mechanisms involving subclinical inflammation. We assessed the relationship between selected dietary constituents and serum high-sensitivity C-reactive protein (hsCRP) concentration in a population-based sample of United States adults. METHODS In this cross-sectional analysis, participants were selected from the US National Health and Nutrition Examination Survey (NHANES) and restricted to those with available data on dietary intake, biochemical and anthropometric measurements from 2001 to 2010. All statistical analyses accounted for the survey design and sample weights by using SPSS Complex Samples v22.0 (IBM Corp, Armonk, NY). RESULTS Of the 17,689 participants analysed, 8607 (48.3%) were men. The mean age was 45.8 years in the overall sample, 44.9 in men and 46.5 in women (p = .047). The age-, race-, sex-, energy intake- and body mass index-adjusted mean dietary intakes of total dietary fibre, polyunsaturated fatty-acids, vitamin E, vitamin A, vitamin B6, total folate, vitamin B family, vitamin C, vitamin K, magnesium, iron, copper and potassium monotonically decreased across increasing hsCRP quarters (p < .001 for all), whereas sugar intake increased (p < .001). In analysis of covariance adjusted for potential confounders (age-, race-, sex-, energy intake- and body weight-) hsCRP levels increased across increasing quarters of sugar intake (p < .001). CONCLUSIONS This study provides further evidence of an association between dietary sugar, polyunsaturated fatty-acids, fibre and antioxidant intake and hsCRP levels, a subclinical inflammation marker. hsCRP concentrations are likely modulated by dietary intake. KEY MESSAGES Serum high-sensitivity C-reactive protein (hsCRP) concentration is positively associated with sugar intake, and negatively with the consumption of minerals, vitamins and polyunsaturated fatty-acids (fruit and vegetables). hsCRP concentrations, and accordingly subclinical inflammation, are likely influenced by dietary intake.

Abstract
UNLABELLED Hypomagnesemia is associated with the development of neuropathy and abnormal platelet activity, both of which are risk factors for diabetic foot ulcer (DFU). This study was carried out to evaluate the effects of magnesium administration on wound healing and metabolic status in subjects with DFU. This randomized, double-blind, placebo-controlled trial was performed among 70 subjects with grade 3 DFU. Subjects were randomly divided into two groups (35 subjects each group) to receive either 250 mg magnesium oxide supplements or placebo daily for 12 weeks. Pre- and post-intervention wound depth and appearance were scored in accordance with the "Wagner-Meggitt's" wound assessment tool. Fasting blood samples were taken at baseline and after the 12-week intervention to assess related markers. After the 12-week treatment, compared with the placebo, magnesium supplementation resulted in a significant increase in serum magnesium (+0.3 ± 0.3 vs. -0.1 ± 0.2 mg/dL, P < 0.001) and significant reductions in ulcer length (-1.8 ± 2.0 vs. -0.9 ± 1.1 cm, P = 0.01), width (-1.6 ± 2.0 vs. -0.8 ± 0.9 cm, P = 0.02), and depth (-0.8 ± 0.8 vs. -0.3 ± 0.5 cm, P = 0.003). In addition, significant reductions in fasting plasma glucose (-45.4 ± 82.6 vs. -10.6 ± 53.7 mg/dL, P = 0.04), serum insulin values (-2.4 ± 5.6 vs. +1.5 ± 9.6 μIU/mL, P = 0.04), and HbA1c (-0.7 ± 1.5 vs. -0.1 ± 0.4%, P = 0.03) and a significant rise in the quantitative insulin sensitivity check index (+0.01 ± 0.01 vs. -0.004 ± 0.02, P = 0.01) were seen following supplementation of magnesium compared with the placebo. Additionally, compared with the placebo, taking magnesium resulted in significant decrease in serum high-sensitivity C-reactive protein (hs-CRP) (-19.6 ± 32.5 vs. -4.8 ± 11.2 mg/L, P = 0.01) and significant increase in plasma total antioxidant capacity (TAC) concentrations (+6.4 ± 65.2 vs. -129.9 ± 208.3 mmol/L, P < 0.001). Overall, magnesium supplementation for 12 weeks among subjects with DFU had beneficial effects on parameters of ulcer size, glucose metabolism, serum hs-CRP, and plasma TAC levels.

Abstract
(1) Background: Dietary fiber intake may provide beneficial effects on the components of metabolic syndrome (MetS); however, observational studies reported inconsistent results for the relationship between dietary fiber intake and MetS risk. We conducted a meta-analysis to quantify previous observational studies and a narrative review to summarize mechanisms involved in the potential relationship. (2) Methods: The literature was searched on PubMed and Web of Science until 28 November 2017. A random-effects model was used to calculate the summary risk estimates. Eleven cross-sectional studies and three cohort studies were included in the meta-analysis. Results from the original studies were reported as odds ratios (ORs) or relative ratios (RRs) of the MetS associated with different levels of dietary fiber intake, and the ORs/RRs comparing the highest with lowest categories of the intake were pooled. (3) Results: For the cross-sectional studies, the pooled OR was 0.70 (95% confidence interval (CI): 0.61-0.82) with evidence of high heterogeneity (I² = 74.4%, p < 0.001) and publication bias (p for Egger's test < 0.001). After removing four studies, results remained significant (OR = 0.67, 95% CI: 0.58-0.78) and the heterogeneity was largely reduced (I² = 32.4%, p = 0.181). For the cohort studies, the pooled RR was 0.86 (95% CI: 0.70-1.06). (4) Conclusion: Although the meta-analysis suggests an inverse association between dietary fiber intake and risk of MetS, and the association was supported by a wide range of mechanism studies, the findings are limited by insufficient cohort data. More prospective studies are needed to further verify the association between dietary fiber intake and the risk of MetS.

Abstract
OBJECTIVE Serum high-sensitivity CRP is a marker of inflammation and an independent predictor of chronic diseases. However, the effect of diet on serum hs-CRP is unclear. The aim of this study was to investigate the relationship between dietary macronutrient intake and serum hs-CRP. DESIGN AND METHODS We recruited 9778 adults, aged 35-65years as part of the MASHAD study. Dietary intake was determined using 24-hour dietary recall and several biochemical parameters including serum hs-CRP were measured. Analysis of covariance was used for assessment of crude and energy-adjusted nutrients across quartiles of serum hs-CRP. To find the association of dietary nutrients intake and serum hs-CRP level, we used logistic regression in different model. RESULTS Unadjusted and adjusted multivariate analyses indicate that there was a significant positive association between dietary protein and sodium intake and serum hs-CRP concentrations. There was also a positive association with dietary fat and cholesterol and serum hs-CRP in the adjusted models. There was a significant inverse association between dietary carbohydrate and fiber consumption and serum hs-CRP in both crude and adjusted models. CONCLUSION We have found a significant positive association between the dietary intake of fat, protein, cholesterol and sodium and hs-CRP level, and an inverse correlation between dietary carbohydrate and fiber and serum hs-CRP in a large representative Iranian population.

Abstract
Previous studies have shown that some dietary components may be implicated in the etiology of spontaneous abortion. However, the possible relationship between diet-related inflammation and the risk of abortion has not yet been investigated. We examined the ability of the literature-derived Dietary Inflammatory Index (DII) to predict the abortion incidence in women suffering from recurrent abortion in a case-control study conducted from April 2010 to March 2011. This included 67 incident cases and 68 controls (frequency matched to cases by age) who attended infertility and miscarriage specialized centers in Tehran, Iran. The DII was computed based on dietary intake assessed using a validated and reproducible 168 item food-frequency questionnaire. Logistic regression models were used to estimate multivariable ORs adjusted for age, education, occupation, and body mass index. Subjects with higher DII scores (i.e., a more pro-inflammatory diet) had higher odds of abortion, with the DII being used as a continuous variable (ORcontinuous = 2.12, 95% CI: 1.02-4.43). When analysis was carried out with DII expressed as a dichotomous variable, women in the pro-inflammatory diet group (DII > 1.24) were at 2.12 times higher odds of having abortion compared with women in the referent group (DII ≤ 1.24) (ORDII>1.24/≤1.24 = 2.12; 95% CI: 1.02-4.43). In the same study, for every 1-unit increase in DII, there was a corresponding increase in interleukin-6 by 0.15 pg/mL, 95% CI (<0.01, 0.28). In conclusion, subjects who consumed a more pro-inflammatory diet were at increased odds of abortion compared with those who consumed a more anti-inflammatory diet.

Abstract
The possible relationship between diet-related inflammation and the risk of prediabetes requires further investigation, especially in non-Western populations. We examined the ability of the dietary inflammatory index (DII) to predict the risk of prediabetes in a case-control study conducted at specialized centers in Esfahan, Iran. A total of 214 incident cases of prediabetes were selected with the nonrandom sampling procedure, and the 200 controls randomly selected from the same clinics were frequency-matched on age (±5 years) and sex. DII scores were computed based on dietary intake assessed using a validated and reproducible 168-item food-frequency questionnaire. Linear and logistic regression models were used to estimate multivariable beta estimates and odds ratios (ORs). Subjects in tertile 3 versus tertile 1 (T3VS1) of DII had significantly higher fasting plasma glucose (DIIT3VS1: b = 4.49; 95% CI 1.89, 7.09), oral glucose tolerance (DIIT3VS1: b = 8.76; 95% CI 1.78, 15.73), HbA1c (DIIT3VS1: b = 0.30; 95% CI 0.17, 0.42), low-density lipoprotein (DIIT3VS1: b = 16.37; 95% CI 11.04, 21.69), triglyceride (DIIT3VS1: b = 21.01; 95% CI 8.61, 33.42) and body fat (DIIT3VS1: b = 2.41; 95% CI 0.56, 4.26) and lower high-density lipoprotein (DIIT3VS1: b = -3.39; 95% CI -5.94, -0.84) and lean body mass (DIIT3VS1: b = -3.11; 95% CI -4.83, -1.39). After multivariate adjustment, subjects in the most pro-inflammatory DII group had 19 times higher odds of developing prediabetes compared with subjects in tertile 1 (DIIT3VS1: OR = 18.88; 95% CI 7.02, 50.82). Similar results were observed when DII was used as a continuous variable, (DIIcontinuous: OR = 3.62; 95% CI 2.50, 5.22). Subjects who consumed a more pro-inflammatory diet were at increased risk of prediabetes compared with those who consumed a more anti-inflammatory diet.

Abstract
BACKGROUND & AIMS There is sparse evidence on the relationship between the Mediterranean diet, Dietary Approaches to Stop Hypertension (DASH) style diet, and metabolic health, especially comparing cardiometabolic phenotypes among in normal weight and obese populations. We aimed to investigate the association of the Mediterranean diet scores (MDS) and DASH index with metabolically healthy obese (MHO) and metabolically obese normal weight (MONW) phenotypes in a representative U.S. POPULATION METHODS MDS and DASH index were calculated using dietary data from 2767 adults aged 20-90 years without any prior diagnosis of cancer or cardiovascular disease from the National Health and Nutrition Examination Survey III, 1988-1994. MHO and MONW individuals were identified using fasting glucose, insulin resistance, blood pressure, triglycerides, C-reactive protein, and high-density lipoprotein-cholesterol. RESULTS Higher MDS was associated with higher odds of MHO phenotype (odds ratio (OR)T3 vs T1, 2.57 [95% confidence interval (CI), 1.04-6.35]; P trend = 0.04), and higher DASH index was associated with lower odds of MONW phenotype (ORT3 vs T1, 0.59 [95% CI, 0.38-0.93]; P trend = 0.03) only in the younger age group (<45 years for men or premenopausal women). No significant associations of MDS and DASH index with MHO and MONW phenotypes were observed in the older age group (≥45 years for men or postmenopausal women). CONCLUSIONS Adherence to Mediterranean diet or DASH style diet was favorably associated with MHO and MONW phenotypes only in the younger age group, suggesting that potential dietary intervention to prevent cardiometabolic disease differ by age group.

Predictive role of the Mediterranean diet on mortality in individuals at low cardiovascular risk: a 12-year follow-up population-based cohort study. J Transl Med 2016; 14:91. [PMID: 27071746 PMCID: PMC4830057 DOI: 10.1186/s12967-016-0851-7] [Citation(s) in RCA: 26] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/08/2016] [Accepted: 04/04/2016] [Indexed: 12/15/2022] Open
Abstract
BACKGROUND Adherence to the Mediterranean diet reduces the risk of all-cause and cardiovascular (CV) mortality and the incidence of CV events. However, most previous studies were performed in high-risk individuals. Our objective was to assess whether the adherence to the Mediterranean diet, evaluated by the MED score, was associated with all-cause and CV mortality and incidence of CV events in individuals at low CV risk from a population-based cohort, after a 12-year mean follow-up. METHODS A cohort of 1658 individuals completed a validated food-frequency questionnaire in 2001-2003. The MED score was calculated by a 0-9 scale. Anthropometric, laboratory measurements, and the vital status were collected at baseline and during 2014. The baseline CV risk was estimated by the Framingham risk score. Participants were divided into two groups: individuals at low risk (CV < 10) and individuals with CV risk ≥ 10. RESULTS During a 12-year mean follow-up, 220 deaths, 84 due to CV diseases, and 125 incident CV events occurred. The adherence to the Mediterranean diet was low in 768 (score 0-2), medium in 685 (score 4-5) and high in 205 (score > 6) individuals. Values of BMI, waist circumference, fasting glucose and insulin significantly decreased from low to high diet adherence only in participants with CV risk ≥ 10. In a Cox-regression model, the hazard ratios (HRs) in low-risk individuals per unit of MED score were: HR = 0.83 (95 % CI 0.72-0.96) for all-cause mortality, HR = 0.75 (95 % CI 0.58-0.96) for CV mortality, and HR = 0.79 (95 % CI 0.65-0.97) for CV events, after multiple adjustments. In individuals with CV risk ≥ 10, the MED score predicted incident CV events (HR = 0.85; 95 % CI 0.72-0.99), while the associations with all-cause (HR = 1.02; 95 % CI 0.90-1.15) and CV mortality (0.94; 95 % CI 0.76-1.15) were not significant. CONCLUSIONS Greater adherence to the Mediterranean diet was associated with reduced fatal and non fatal CV events, especially in individuals at low CV risk, thus suggesting the usefulness of promoting this nutritional pattern in particular in healthier individuals.

Abstract
BACKGROUND Depression is a major global public health concern. The aetiology of depression is partly unclear; however, intake of nutrients, such as magnesium, have been suggested to affect depressive symptoms and modify depression risk. METHODS This research is a part of the Kuopio Ischemic Heart Disease Risk Factor (KIHD) Study, conducted on a sample of 2320 Eastern Finnish men aged 42-61 years old at the baseline. Magnesium intake was assessed by a 4-day food record. Hospital discharge diagnosis of unipolar depressive disorder was used as an outcome variable. RESULTS Participants in the middle tertile of dietary magnesium intake had a statistically significantly decreased risk of getting a hospital discharge diagnosis of depression compared to participants in the lowest tertile of magnesium intake (HR 0.49, CI 0.25-0.95, P=0.035) in the prospective setting after multivariable adjustments. In addition, an inverse association between magnesium intake and the risk of depression was found when the combined middle and highest tertiles of magnesium intake were compared with the lowest tertile (HR 0.53, CI 0.29-0.95, P=0.033). LIMITATIONS Our findings may not be generalizable to individuals below middle-age or women. Moreover, we were unable to consider cases with mild depression in the longitudinal setting. CONCLUSIONS The results of this study suggest that magnesium intake may have an effect on the risk to develop depression. Further studies are needed to investigate whether sufficient magnesium intake could have implications for prevention or treatment of depression.

Abstract
OBJECTIVES High-sensitivity C-reactive protein (hsCRP) is possibly related to osteoarthritis (OA) progression and a variety of OA-related symptoms. This study aimed to examine associations between cigarette smoking, betel quid chewing and alcohol consumption and hsCRP in early radiographic knee OA. DESIGN Cross-sectional health examination survey. SETTING This primary study was conducted in a health examination centre in China. PARTICIPANTS 936 (656 men and 280 women) patients with early radiographic knee OA were included in this cross-sectional study. PRIMARY AND SECONDARY OUTCOME MEASURES Smoking status was classified into four levels based on daily smoking habit: 0/day, 1-10/day, 11-20/day and >20/day. Betel quid chewing and alcohol consumption status was divided into 'Yes' or 'No'. Early radiographic knee OA was defined as Kellgren Lawrence (K-L) grade 1 or 2 in at least one leg, and elevated hsCRP was assessed as ≥ 3.0 mg/L. RESULTS After adjustment for a number of potential confounding factors, a significant positive association between cigarette smoking and hsCRP was observed in the multivariable model. The multivariable-adjusted ORs (95% CI) of elevated hsCRP (≥ 3.0 mg/L) in the second (1-10/day, n=133), third (11-20/day, n=59) and highest (>20/day, n=104) cigarette smoking categories were 1.54 (95% CI 0.91 to 2.61), 1.27 (95% CI 0.57 to 2.79) and 2.09 (95% CI 1.20 to 3.64), respectively, compared with the non-smoker category (n=640). In addition, there was a positive dose-response relationship between cigarette smoking and elevated hsCRP (p for trend=0.01). No significant associations between betel quid chewing and alcohol consumption and hsCRP were observed in the multivariable model. CONCLUSIONS This study indicated that cigarette smoking was positively associated with serum hsCRP level in patients with early radiographic knee OA. However, in view of the nature of cross-sectional designs, the results need to be confirmed by further prospective studies.

Abstract
The aim of the study was to examine the cross-sectional association between high-sensitivity C-reactive protein (hsCRP) and hyperuricemia (HU). The hsCRP was measured by latex turbidity method. Uric acid was detected on Beckman Coulter AU 5800. HU was defined as uric acid ≥416 μmol/L for the male population and ≥360 μmol/L for the female population. A multivariable logistic analysis model was applied to test the association after adjusting for a number of potential confounding factors. A total of 1935 subjects were included in this study. According to the multivariable regression model, the relative odds of the prevalence of HU were increased by 0.56 times in the third quintile (OR 1.56, 95 % CI 1.03-2.38, P = 0.04), 0.55 times in the fourth quintile (OR 1.55, 95 % CI 1.01-2.36, P = 0.04) and 0.96 times in the fifth quintile (OR 1.96, 95 % CI 1.29-2.98, P < 0.01) of hsCRP comparing with the lowest quintile, and P for trend was smaller than 0.01. In the male population, a positive association existed in the highest quintile of hsCRP (OR 1.66, 95 % CI 1.04-2.66, P = 0.04), and P for trend was 0.07. In the female population, the multivariable-adjusted ORs (95 % CI) of HU in the fourth and fifth quintile of hsCRP were 3.02 (95 % CI 1.09-8.35, P = 0.03) and 3.66 (95 % CI 1.36-9.89, P = 0.01), respectively, and P for trend was smaller than 0.01. The findings of this cross-sectional study suggest that the hsCRP level is positively associated with the prevalence of HU. Level of evidence Cross-sectional study, Level III.

Abstract
Background The cardio-protective effects of flavonoids are still controversial; many studies referred to the benefits of specific foods, such as soy, cocoa, tea. A population-based cohort of middle-aged adults, coming from a semi-rural area where the consumption of those foods is almost negligible, was studied. Aims The primary objective was establishing if flavonoid intake was inversely associated with the cardiovascular (CV) risk evaluated after 12-year follow-up; the associations between flavonoid intake and CV incidence and mortality and all-cause mortality were also evaluated. Methods In 2001–2003, a cohort of 1,658 individuals completed a validated food-frequency questionnaire. Anthropometric, laboratory measurements, medical history and the vital status were collected at baseline and during 2014. The CV risk was estimated with the Framingham risk score. Results Individuals with the lowest tertile of flavonoid intake showed a worse metabolic pattern and less healthy lifestyle habits. The 2014 CV risk score and the increase in the risk score from baseline were significantly higher with the lowest intake of total and all subclasses of flavonoids, but isoflavones, in a multiple regression model. During follow-up, 125 CV events and 220 deaths (84 of which due to CV causes) occurred. CV non-fatal events were less frequent in individuals with higher flavonoid intake (HR = 0.64; 95%CI 0.42–1.00 and HR = 0.46; 95%CI 0.28–0.75 for the second and third tertiles, respectively) in Cox-regression models, after multiple adjustments. All subclasses of flavonoids, but flavones and isoflavones, were inversely correlated with incident CV events, with HRs ranging from 0.42 (flavan-3-ols) to 0.56 (anthocyanidins). Being in the third tertile of flavan-3-ols (HR = 0.68; 95% CI 0.48–0.96), anthocyanidins (HR = 0.66; 95% CI 0.46–0.95) and flavanones (HR = 0.59; 95% CI 0.40–0.85) was inversely associated with all-cause mortality. Total and subclasses of flavonoids were not significantly associated with the risk of CV mortality. Conclusions Flavonoid intake was inversely associated with CV risk, CV non-fatal events and all-cause mortality in a cohort with a low consumption of soy, tea and cocoa, which are typically viewed as the foods responsible for flavonoid-related benefits.

Abstract
BACKGROUND & AIMS Several trace elements are involved in insulin signal transduction and glucose metabolism. Our aim for this present study was to determine the levels of three important elements-magnesium, chromium, and zinc-as well as one oxidative stress marker-malondialdehyde (MDA)-in young type 1 diabetic patients at different periods of their growth, and to realize the relationships between trace elements, oxidative stress, and growth stages. METHODS A total of 88 patients with type 1 diabetes mellitus in different growth stages and 76 gender- and age-matched healthy subjects were included in this study. The levels of MDA were measured through HPLC using a C-18 column. Zinc, magnesium, and chromium concentrations in serum were assessed using atomic absorption spectrophotometry. RESULTS We found higher levels of blood malondialdehyde (MDA; p < 0.001), significantly lower levels of magnesium (p < 0.001), and no differences in zinc and chromium levels (p = 0.153 and 0.515, respectively) in younger type 1 diabetic subjects relative to those of control subjects. Only 3.4% (3/88) of younger diabetic subjects exhibited hypomagnesemia; similar results were obtained when comparing different subgroups: children, adolescents, and adults. We also observed no differences in the levels of the three elements between the genders and among the growth stages (p > 0.05) of the diabetic subjects. There were no correlations between the three trace elements and HbA1C, diabetes duration, and insulin dose/BMI (all p > 0.05), but there was a significant difference between zinc levels and insulin dose/BMI (p = 0.043) in the diabetic patients. CONCLUSIONS We found elevated blood MDA, decreased magnesium, and no changes in zinc and chromium levels in younger type 1 diabetic subjects relative to those of control subjects. Only 3.4% of younger diabetic subjects exhibited hypomagnesemia. Whether magnesium supplementation is suitable for improving insulin sensitivity and decreasing oxidative stress and inflammation will require confirmation through additional studies.

OBJECTIVE To establish whether there is a relationship between serum magnesium (Mg) concentration and radiographic knee osteoarthritis (OA). METHODS There were 2855 subjects in this cross-sectional study. Serum Mg concentration was measured using the chemiluminescence method. Radiographic OA of the knee was defined as changes consistent with Kellgren-Lawrence (K-L) grade 2 on at least 1 side. Mg concentration was classified into 1 of 4 quartiles: ≤ 0.87, 0.88-0.91, 0.92-0.96, or ≥ 0.97 mmol/l. Multivariable logistic analysis was used to test the association between serum Mg and radiographic knee OA after adjustment for potentially confounding factors. The OR with 95% CI for the association between radiographic knee OA and serum Mg concentration were calculated for each quartile. The quartile with the lowest value was regarded as the reference category. RESULTS Significant association between serum Mg concentration and radiographic knee OA was observed in the model after adjustment for age, sex, and body mass index, as well as in the multivariable model. The multivariable-adjusted OR (95% CI) for radiographic knee OA in the second, third, and fourth serum Mg concentration quartiles were 0.90 (95% CI 0.71-1.13), 0.92 (95% CI 0.73-1.16), and 0.72 (95% CI 0.57-0.92), respectively, compared with the lowest (first) quartile. A clear trend (p for trend was 0.01) was observed. The relative odds of radiographic knee OA was decreased by 0.72 times in the fourth serum Mg quartile compared with the lowest quartile. CONCLUSION Serum Mg concentration may have an inverse relationship with radiographic OA of the knee.

Abstract
ncreasing evidence has suggested an association between dietary magnesium intake and metabolic syndrome. However, previous research examining dietary magnesium intake and metabolic syndrome has produced mixed results. Our objective was to determine the relationship between dietary magnesium intake and metabolic syndrome in the adult population using a dose-response meta-analysis. We searched the PubMed, Embase and the Cochrane Library databases from August, 1965, to May, 2014. Observational studies reporting risk ratios with 95% confidence intervals (CIs) for metabolic syndrome in ≥ 3 categories of dietary magnesium intake levels were selected. The data extraction was performed independently by two authors, and the quality of the studies was evaluated using the Risk of Bias Assessment Tool for Nonrandomized Studies (RoBANS). Based on eight cross-sectional studies and two prospective cohort studies, the pooled relative risks of metabolic syndrome per 150 mg/day increment in magnesium intake was 0.88 (95% CI, 0.84-0.93; I(2) = 36.3%). The meta-regression model showed a generally linear, inverse relationship between magnesium intake (mg/day) and metabolic syndrome. This dose-response meta-analysis indicates that dietary magnesium intake is significantly and inversely associated with the risk of metabolic syndrome. However, randomized clinical trials will be necessary to address the issue of causality and to determine whether magnesium supplementation is effective for the prevention of metabolic syndrome.

[PMID: 25837205 DOI: 10.1016/j.nut.2014.10.018] [Citation(s) in RCA: 37] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/15/2014] [Revised: 10/02/2014] [Accepted: 10/30/2014] [Indexed: 12/20/2022]
Abstract
OBJECTIVES Because of conflicting results of presented studies, the aim of this systematic review and meta-analysis of randomized clinical trials (RCTs) was to examine the effect of non-soy legume intake on inflammatory markers and C-reactive protein (CRP). METHODS We searched Pubmed, ISI Web of Knowledge, SCOPUS, and Google Scholar for relevant studies up to July 2013, using medical subject headings [MeSH] and other related keywords. Nine RCTs were systematically reviewed to examine the effect of non-soy legume consumption on inflammatory markers. Eight studies involving 464 participants were included in the meta-analysis. RESULTS The results of the meta-analysis showed that non-soy legume consumption had a trend toward a significant effect on decreasing CRP and high-sensitivity (hs)-CRP concentrations (mean difference (MD) = -0.21; 95% confidence interval [CI], -0.44 to 0.02; P = 0.068). There was no overall effect of non-soy legume consumption on CRP or hs-CRP levels in either the parallel or crossover study designs. Our subgroup analysis of CRP type and study design, showed that non-soy legume intake had a significant effect on CRP levels in parallel studies (MD = -1.01; 95% CI, -1.78 to -0.23; P = 0.011) and a significant effect on hs-CRP levels (MD = -0.53; 95% CI, -0.95 to -0.11; P = 0.014) and in the crossover sub group (MD = -0.68; 95% CI, -1.28 to -0.08; P = 0.026). CONCLUSIONS This review of RCTs showed that non-soy legume consumption may contribute to reductions in CRP and hs-CRP concentrations. However, further controlled clinical trials are needed to investigate the effect of non-soy legume intake on other inflammatory markers.
