Abstract
INTRODUCTION The purpose of this study is to examine the effects of oat supplementation on serum lipid in a population of adults with mild hypercholesterolemia and reveal the underlying mechanisms with serum untargeted metabolomics. METHODS AND RESULTS In this placebo-controlled trial, 62 participants from Nanjing, China, with mild elevations in cholesterol are randomly assigned to receive 80 g oats (containing 3 g beta-glucan) or rice daily for 45 days. Fasting blood samples are collected at the beginning, middle, and end of the trial. Compared with the rice group, oat consumption significantly decreases serum total cholesterol (TC) (-8.41%, p = 0.005), low-density lipoprotein cholesterol (LDL-c) (-13.93%, p = 0.001), and non high-density lipoprotein cholesterol (non-HDL-c) (-10.93%, p = 0.017) levels. There are no significant between-group differences in serum triglyceride (TG), apolipoprotein B (Apo B), glycated albumin, or fasting blood glucose levels. An orthogonal partial least squares discriminant analysis (OPLS-DA) suggests a clear separation in metabolic profiles between the groups after the intervention. Twenty-one metabolites in the oat group are significantly different from those in the rice group, among which 14 metabolites show a decreased trend. In comparison, seven metabolites show an increased trend. Correlations analysis from both groups indicate that most metabolites [e.g., sphinganine and phosphatidylcholine (PC)(20:5(5Z,8Z,11Z,14Z,17Z)/20:1(11Z))] have positive correlations with serum cholesterol levels. Kyoto Encyclopedia of Gene and Genomes pathway analysis suggests that oat consumption regulated glycerophospholipid, alanine, aspartate and glutamate, sphingolipid, and retinol metabolism. CONCLUSION Oat consumption has beneficial effects on serum lipids profiles. The underlying mechanisms involve glycerophospholipid, alanine, aspartate and glutamate, sphingolipid, and retinol metabolism in adults.

Effects of different delivering matrices of β-glucan on lipids in mildly hypercholesterolaemic individuals: a meta-analysis of randomised controlled trials. Br J Nutr 2020; 125:294-307.

Abstract
Abstractβ-Glucan has been reported for its health benefits on blood lipids in hypercholesterolaemic individuals for years. However, people have paid little attention to the effects of β-glucan in populations with mild hypercholesterolaemia as well as the various delivering matrices. Our objective was to perform a meta-analysis to analyse the effects of β-glucan with different delivering matrices in mildly hypercholesterolaemic individuals. After conducting a comprehensive search in Web of Science, PubMed, Scopus and Cochrane Library, a total of twenty-one randomised controlled trials involving 1120 participants were identified to measure the pooled effect. The overall results indicated that consuming a dose of ≥3 g/d of β-glucan for at least 3 weeks could significantly reduce total cholesterol (TC) (−0·27 mmol/l, 95 % CI −0·33, −0·21, P < 0·001) and LDL-cholesterol (−0·26 mmol/l, 95% CI −0·32, −0·20, P < 0·001) compared with the control group in mildly hypercholesterolaemic individuals, while no significant difference was observed in TAG (−0·03 mmol/l, 95% CI −0·11, 0·06, P = 0·521) and HDL-cholesterol (0·01 mmol/l, 95% CI −0·03, 0·04, P = 0·777). There was evidence for modest unexplained heterogeneity in the meta-analysis. In conclusion, β-glucan can significantly reduce risk factors like TC and LDL-cholesterol for CVD in mildly hypercholesterolaemic individuals; furthermore, it appears that the effects of food matrices with both ‘solid products’ and ‘liquid products’ where β-glucan was incorporated into were ranked as the best way to exert its beneficial properties, while ‘liquid’ and ‘solid’ products were ranked as the second and third positions, respectively.

Abstract
OBJECTIVES This study examined how environmental, health, social, behavioural and genetic factors interact to contribute to myocardial infarction (MI) risk. DESIGN Survey data collected by Wisconsin Longitudinal Study (WLS), USA, from 1957 to 2011, including 235 environmental, health, social and behavioural factors, and 77 single- nucleotide polymorphisms were analysed for association with MI. To identify associations with MI we utilized recursive partitioning and random forest prior to logistic regression and chi-squared analyses. PARTICIPANTS 6198 WLS participants (2938 men; 3260 women) who (1) had a MI before 72 years and (2) had a MI between 65 and 72 years. RESULTS In men, stroke (LR OR: 5.01, 95% CI 3.36 to 7.48), high cholesterol (3.29, 2.59 to 4.18), diabetes (3.24, 2.53 to 4.15) and high blood pressure (2.39, 1.92 to 2.96) were significantly associated with MI up to 72 years of age. For those with high cholesterol, the interaction of smoking and lower alcohol consumption increased prevalence from 23% to 41%, with exposure to dangerous working conditions, a factor not previously linked with MI, further increasing prevalence to 50%. Conversely, MI was reported in <2.5% of men with normal cholesterol and no history of diabetes or depression. Only stroke (4.08, 2.17 to 7.65) and diabetes (2.71, 1.81 to 4.04) by 65 remained significantly associated with MI for men after age 65. For women, diabetes (5.62, 4.08 to 7.75), high blood pressure (3.21, 2.34 to 4.39), high cholesterol (2.03, 1.38 to 3.00) and dissatisfaction with their financial situation (4.00, 1.94 to 8.27) were significantly associated with MI up to 72 years of age. Conversely, often engaging in physical activity alone (0.53, 0.32 to 0.89) or with others (0.34, 0.21 to 0.57) was associated with the largest reduction in odds of MI. Being non-diabetic with normal blood pressure and engaging in physical activity often lowered prevalence of MI to 0.2%. Only diabetes by 65 (4.25, 2.50 to 7.24) and being exposed to dangerous work conditions at 54 (2.24, 1.36 to 3.69) remained significantly associated with MI for women after age 65, while still menstruating at 54 (0.46, 0.23 to 0.91) was associated with reduced odds of MI. CONCLUSIONS Together these results indicate important differences in factors associated with MI between the sexes, that combinations of factors greatly influence the likelihood of MI, that MI-associated factors change and associations weaken after 65 years of age in both sexes, and that the limited genotypes assessed were secondary to environmental, health, social and behavioral factors.

Abstract
BACKGROUND Potential effects of resveratrol consumption on cardiovascular disease risk factors and body weight in overweight/obese adults have not been fully elucidated. Our present analysis was to evaluate the effects of resveratrol consumption on risk markers related to cardiovascular health in overweight/obese Individuals. METHODS Multiple literature databases were systematically searched, and 21 studies were included. Effect sizes were expressed as weighted mean difference (WMD) and 95% confidence interval (CI), and heterogeneity was assessed with the I2 test. Publication bias and subgroup analyses were also performed. RESULTS There were variations in reporting quality of included studies. Resveratrol intervention significantly lowered total cholesterol (WMD, -0.19 mmol/L; 95% CI, -0.32 to -0.06; P = 0.004), systolic blood pressure (WMD, -2.26 mmHg; 95% CI, -4.82 to -0.49; P = 0.02), and fasting glucose (WMD, -0.22 mmol/L; 95% CI, -0.42 to -0.03; P = 0.03). Heterogeneity was noted for these outcomes (35.6%, 38.7% and 71.4%, respectively). Our subgroup analysis showed significant reductions in total cholesterol, systolic blood pressure, diastolic blood pressure, glucose, and insulin in subjects ingesting higher dose of resveratrol (≥300 mg/day). CONCLUSION Our finding provides evidence that daily resveratrol consumption might be a candidate as an adjunct to pharmacological management to better prevent and control cardiovascular disease in overweight/obese individuals.

Abstract
Evidence from animal and observational studies has supported the beneficial effects of beta-glucan intake on glycemic control, but intervention studies in hypercholesterolemic crowd have generated mixed results and have not been systematically examined. In the present study, we aimed to quantitatively evaluate the relation between beta-glucan consumption from oats or barley on glycemic control in hypercholesterolemic individuals. A systematic literature review was conducted for relevant published randomized controlled trials studies (RCTs) in electronic databases through July 2014. Twelve trials with a total of 603 subjects were included in the meta-analysis. Beta-glucan consumption did not significantly affect measures of glycemic control. Summary estimates of weighted mean differences (WMD) and 95% confidence interval was 0.05 mmol/L (-0.11, 0.02) for fasting glucose concentration and 0.75 pmol/L (-1.82, 3.32) for fasting insulin concentrations. In conclusion, there was not a significant overall effect of beta-glucan intake on improvements of fasting glucose and insulin concentrations in hypercholesterolemic subjects.

Abstract
The question of what motivates individuals to assume healthy eating habits remains unanswered. The purpose of this descriptive survey is to explore health-related feared possible selves in relation to dietary beliefs and behavior in adults. A convenience sample of 74 middle-aged employees of a health maintenance organization completed self-administered questionnaires. Health-related feared selves, current health perception, knowledge of diet-health association, dietary self-efficacy, dietary intention and intake were measured. Health-related fears were the most frequently reported feared selves, but very few of those represented illnesses and none were related to dietary intake. The number of health and body weight related fears was significantly associated with lower dietary self-efficacy and weaker intention to eat in a healthy manner. Multivariate analysis showed self-efficacy to be the only significant predictor of dietary intention. These adults may not have perceived being at risk for diet-associated illnesses, and so their feared selves did not motivate them to eat in a healthy manner. Research on the effect of hoped for health related possible selves and the perceived effectiveness of diet in reducing health risk are recommended.

Abstract
OBJECTIVE To assess whether a diet containing foods enriched with β-glucans (3.6 g/d), folic acid (1600 μg/d), long-chain (800 mg/d) and short-chain (400 mg/d) n-3 fatty acids, and tocopherols (120 mg/d) is able to modulate positively the cardiovascular risk profile in people at slightly increased cardiovascular risk. METHODS Sixteen subjects with mild plasma lipid abnormalities were studied according to a randomized crossover design. After a 2-week run-in period, they followed a diet containing baked products enriched with active nutrients (active diet) or a diet containing the same products but without active nutrients (control diet) for 1 month and then crossed over to the other diet. At the end of each period, a test meal of the same composition as the corresponding diet was administered, and plasma samples were obtained before and for 6 hours after the meal. Hunger and satiety were evaluated by the visual analog scale at fasting and after the meal. RESULTS Fasting plasma triglycerides were significantly lower after the active versus the control diet (1.56 ± 0.18 vs 1.74 ± 0.16 mmol/l, p < 0.05), as was the postprandial level of chylomicron triglycerides and the insulin peak (p < 0.05). The active diet also reduced fasting homocysteine (8 ± 0.6 vs 10 ± 0.8 μmol/l, p < 0.05) and the feeling of hunger at the fifth and sixth hour (p < 0.05). CONCLUSIONS Baked functional products enriched with n-3 fatty acids, folates, β-glucans, and tocopherols within the context of a balanced diet lower fasting and postprandial plasma triglycerides, fasting homocysteinemia, and the postprandial insulin peak. They induce a greater feeling of satiety with possible beneficial implications on energy intake.

Abstract
The aim of the study was to evaluate whether two dietary approaches recommended for diabetes mellitus and cardiovascular prevention-high-MUFA or complex carbohydrates/fiber-differently influence inflammation. A 4-week crossover study in 12 individuals with type 2 diabetes was performed. Fasting and postprandial hs-CRP plasma levels were not significantly different after a high-carbohydrate/high-fiber/low-glycemic index (CHO/fiber) and a high-MUFA diet. Compared with fasting, hs-CRP levels decreased significantly after the MUFA but not after the CHO/fiber meal. Triglyceride-rich lipoproteins were significantly lower after the CHO/fiber than the MUFA diet. At fasting and postprandially, hs-CRP correlated with triglyceride in whole plasma, chylomicrons, small and large VLDL after the CHO/fiber but not after the MUFA diet. In conclusion, a MUFA-rich diet and a carbohydrate/fiber-rich diet induced similar effects on plasma hs-CRP concentrations. However, these dietary approaches seem to influence hs-CRP levels through different mechanisms. i.e., direct acute postprandial effects by MUFA and triglyceride-rich lipoproteins mediated effects by CHO/fiber.

Abstract
OBJECTIVE To compare macronutrient intakes of Swedish children and adolescents to population goals; to identify the major sources of energy, fat, saturated fat and sucrose; and to simulate the effect adherence to current food-based dietary guidelines (FBDG) would have on saturated fat and sucrose intakes. DESIGN Cross-sectional study. From 24 h recall data, food groups contributing most to energy, fat, saturated fat and sucrose were identified. Based on the prevailing consumption of foods mentioned in the FBDG, we simulated five scenarios: changes in milk and yoghurt; cheese; energy-dense, nutrient-dilute foods; soft drinks; and burger and sausage consumption. SETTING Stockholm and Örebro (Sweden) in 1998-1999. SUBJECTS Children (n 551, 9·6 years) and adolescents (n 569, 15·5 years) participating in the European Youth Heart Study. RESULTS Intakes of saturated fat and sucrose exceeded population goals in all age and gender subgroups. Compliance to the goal for saturated fat was lower in children, particularly boys. Compliance to the sucrose goal was lower among adolescents. The major sources of energy, fat, saturated fat and sucrose in the diet reflect not only the traditional Swedish diet but also the influence of energy-dense, nutrient-dilute foods. The simulations suggest that a combination of FBDG is required to bring both saturated fat and sucrose intakes in line with recommendations. CONCLUSIONS Widespread adherence to a combination of FBDG could theoretically bring mean intakes in line with population goals. The effect on overall nutrient intakes as well as consumer acceptance of such changes needs to be considered.
