Lee YM, Kim Y. Is Curcumin Intake Really Effective for Chronic Inflammatory Metabolic Disease? A Review of Meta-Analyses of Randomized Controlled Trials. Nutrients 2024; 16:1728. [PMID: 38892660 PMCID: PMC11174746 DOI: 10.3390/nu16111728] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/08/2024] [Revised: 05/28/2024] [Accepted: 05/29/2024] [Indexed: 06/21/2024] Open
Abstract
This review aimed to examine the effects of curcumin on chronic inflammatory metabolic disease by extensively evaluating meta-analyses of randomized controlled trials (RCTs). We performed a literature search of meta-analyses of RCTs published in English in PubMed®/MEDLINE up to 31 July 2023. We identified 54 meta-analyses of curcumin RCTs for inflammation, antioxidant, glucose control, lipids, anthropometric parameters, blood pressure, endothelial function, depression, and cognitive function. A reduction in C-reactive protein (CRP) levels was observed in seven of ten meta-analyses of RCTs. In five of eight meta-analyses, curcumin intake significantly lowered interleukin 6 (IL-6) levels. In six of nine meta-analyses, curcumin intake significantly lowered tumor necrosis factor α (TNF-α) levels. In five of six meta-analyses, curcumin intake significantly lowered malondialdehyde (MDA) levels. In 14 of 15 meta-analyses, curcumin intake significantly reduced fasting blood glucose (FBG) levels. In 12 of 12 meta-analyses, curcumin intake significantly reduced homeostasis model assessment of insulin resistance (HOMA-IR). In seven of eight meta-analyses, curcumin intake significantly reduced glycated hemoglobin (HbA1c) levels. In eight of ten meta-analyses, curcumin intake significantly reduced insulin levels. In 14 of 19 meta-analyses, curcumin intake significantly reduced total cholesterol (TC) levels. Curcumin intake plays a protective effect on chronic inflammatory metabolic disease, possibly via improved levels of glucose homeostasis, MDA, TC, and inflammation (CRP, IL-6, TNF-α, and adiponectin). The safety and efficacy of curcumin as a natural product support the potential for the prevention and treatment of chronic inflammatory metabolic diseases.

Curcumin/turmeric supplementation could improve blood pressure and endothelial function: A grade-assessed systematic review and dose-response meta-analysis of randomized controlled trials. Clin Nutr ESPEN 2024; 59:194-207. [PMID: 38220376 DOI: 10.1016/j.clnesp.2023.12.009] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/02/2023] [Revised: 11/14/2023] [Accepted: 12/07/2023] [Indexed: 01/16/2024]
Abstract
BACKGROUND AND PURPOSE A number of studies have examined the impact of curcumin/turmeric on blood pressure and the factors allegedly responsible for hypertension. In this systematic review and meta-analysis, we tried to sum up the existing literature on randomized controlled trials (RCTs) investigating this hypothesis. METHODS Online databases (PubMed, Scopus, Web of Science Core Collection, Cochrane Library, and Google Scholar) were searched from inception up to October 2022. We used the cochrane quality assessment tool to evaluate the risk of bias. Outcomes of interest included systolic blood pressure (SBP), diastolic blood pressure (DBP), blood levels of vascular cell adhesion molecule-1 (VCAM-1) and intracellular adhesion molecule-1 (ICAM-1), flow-mediated vasodilation (FMD), and pulse-wave velocity (PWV). Weighted mean differences (WMDs) were derived and reported. In case of significant between-study heterogeneity, subgroup analyses were carried out. Significance level was considered as P-values<0.05. RESULTS Finally, 35 RCTs out of 4182 studies were included. Our findings suggested that curcumin/turmeric supplementation significantly improved SBP (WMD: -2.02 mmHg; 95 % CI: -2.85, -1.18), DBP (WMD: -0.82 mmHg; 95 % CI: -1.46, -0.18), VCAM-1 (WMD: -39.19 ng/mL; 95 % CI: -66.15, -12.23), and FMD (WMD: 2.00 %; 95 % CI: 1.07, 2.94). However, it did not significantly change levels of ICAM-1 (WMD: -17.05 ng/ml; 95 % CI: -80.79, 46.70), or PWV (WMD: -79.53 cm/s; 95 % CI: -210.38, 51.33). CONCLUSION It seems that curcumin/turmeric supplementation could be regarded as a complementary method to improve blood pressure and endothelial function. However, further research is needed to clarify its impact on inflammatory adhesion molecules in the circulation.

Abstract
Metabolic syndrome (MetS) is a growing global health problem. Evidence suggests that diets rich in phytochemical-containing herbs and spices can contribute to reducing the risk of chronic diseases. This review assesses the scope of evidence supporting the use of herbs and spices in the diet for the prevention or treatment of MetS and its associated health conditions. A search of the PubMed, Scopus and Google Scholar databases was carried out to assess the available clinical evidence for culinary doses of commonly used herbs and spices. Trials that were measuring health factors related to metabolic disorders in healthy individuals, or the health of individuals with MetS or associated diseases, were included. Out of a total of 1738 papers identified, there were 142 relevant studies on black pepper, chilli, cardamom, cinnamon, coriander, cumin, fennel, fenugreek, garlic, ginger, nigella seed, rosemary, sage and turmeric. No relevant research was found for cloves, mint, oregano, parsley or thyme. Cinnamon, fenugreek and ginger were the herbs/spices with the most published trials on them and that showed promise for glycaemic control. Cardamom appears to have potential to reduce inflammatory markers, and cinnamon, ginger and turmeric to reduce blood lipids. Patients with type 2 diabetes were the population most likely to be included in studies, but the preventative benefits of herbs/spices in healthy populations were also investigated, particularly for chilli, ginger and cinnamon. There is evidence for the beneficial effect of culinary doses of many common herbs/spices in the prevention and treatment of MetS and associated disorders.

Abstract
INTRODUCTION Glycemic control is of utmost importance both as a preventive measure in individuals at risk of diabetes and in the management of patients with disturbed glycemia. Turmeric/curcumin has been extensively studied in this field. In the present systematic review and meta-analysis, we aimed at investigating the impact of turmeric/curcumin supplementation on glycemic control. METHODS Major online databases (PubMed, Scopus, Web of Science, Cochrane Library and Google Scholar) were systematically searched from inception up to October 2022. Relevant randomized controlled trials (RCTs) meeting our eligible criteria were included. Weighted mean differences (WMDs) with confidence intervals (CIs) were expressed using a random-effect model. Subgroup analyses were conducted to find the sources of heterogeneities. To detect risk of bias in the included studies, we used the Cochrane risk-of-bias tool. The registration number was CRD42022374874. RESULTS Out of 4182 articles retrieved from the initial search, 59 RCTs were included. Our findings suggested that turmeric/curcumin supplementation was significantly effective in improving fasting blood sugar (WMD: 4.60 mg/dl; 95% CI: 5.55, -3.66), fasting insulin levels (WMD: 0.87 μIU/ml; 95% CI: 1.46, -0.27), hemoglobin A1c (HbA1c) (WMD: 0.32%; 95% CI: 0.45, -0.19), and homeostatic model assessment of insulin resistance (HOMA-IR) (WMD: 0.33; 95% CI: 0.43, -0.22). CONCLUSION Our results indicate that turmeric/curcumin supplementation can be considered as a complementary method in the management of disturbed glycemia.

Abstract
The consumption of food-derived products, including the regular intake of pepper, is increasingly evaluated for its potential benefits in protecting against diverse metabolic complications. The current study made use of prominent electronic databases including PubMed, Google Scholar, and Scopus to retrieve clinical evidence linking the intake of black and red pepper with the amelioration of metabolic complications. The findings summarize evidence supporting the beneficial effects of black pepper (Piper nigrum L.), including its active ingredient, piperine, in improving blood lipid profiles, including reducing circulating levels of total cholesterol, low-density lipoprotein cholesterol, and triglycerides in overweight and obese individuals. The intake of piperine was also linked with enhanced antioxidant and anti-inflammatory properties by increasing serum levels of superoxide dismutase while reducing those of malonaldehyde and C-reactive protein in individuals with metabolic syndrome. Evidence summarized in the current review also indicates that red pepper (Capsicum annum), together with its active ingredient, capsaicin, could promote energy expenditure, including limiting energy intake, which is likely to contribute to reduced fat mass in overweight and obese individuals. Emerging clinical evidence also indicates that pepper may be beneficial in alleviating complications linked with other chronic conditions, including osteoarthritis, oropharyngeal dysphagia, digestion, hemodialysis, and neuromuscular fatigue. Notably, the beneficial effects of pepper or its active ingredients appear to be more pronounced when used in combination with other bioactive compounds. The current review also covers essential information on the metabolism and bioavailability profiles of both pepper species and their main active ingredients, which are all necessary to understand their potential beneficial effects against metabolic diseases.

Abstract
Turmeric (Curcuma longa) has been used for thousands of years for the prevention and treatment of various chronic diseases. Curcumin is just one of >200 ingredients in turmeric. Almost 7000 scientific papers on turmeric and almost 20,000 on curcumin have been published in PubMed. Scientific reports based on cell culture or animal studies are often not reproducible in humans. Therefore, human clinical trials are the best indicators for the prevention and treatment of a disease using a given agent/drug. Herein, we conducted an extensive literature survey on PubMed and Scopus following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. The keywords "turmeric and clinical trials" and "curcumin and clinical trials" were considered for data mining. A total of 148 references were found to be relevant for the key term "turmeric and clinical trials", of which 70 were common in both PubMed and Scopus, 44 were unique to PubMed, and 34 were unique to Scopus. Similarly, for the search term "curcumin and clinical trials", 440 references were found to be relevant, of which 70 were unique to PubMed, 110 were unique to Scopus, and 260 were common to both databases. These studies show that the golden spice has enormous health and medicinal benefits for humans. This Review will extract and summarize the lessons learned about turmeric and curcumin in the prevention and treatment of chronic diseases based on clinical trials.

Abstract
Turmeric and its prominent bioactive compound, curcumin, have been the subject of many investigations with regard to their impact on inflammatory and oxidative balance in the body. In this systematic review and meta-analysis, we summarized the existing literature on randomized controlled trials (RCTs) which examined this hypothesis. Major databases (PubMed, Scopus, Web of Science, Cochrane Library and Google Scholar) were searched from inception up to October 2022. Relevant studies meeting our eligibility criteria were obtained. Main outcomes included inflammatory markers (i.e. C-reactive protein(CRP), tumour necrosis factorα(TNF-α), interleukin-6(IL-6), and interleukin 1 beta(IL-1β)) and markers of oxidative stress (i.e. total antioxidant capacity (TAC), malondialdehyde(MDA), and superoxide dismutase (SOD) activity). Weighted mean differences (WMDs) were reported. P-values < 0.05 were considered significant. Sixty-six RCTs were included in the final analysis. We observed that turmeric/curcumin supplementation significantly reduces levels of inflammatory markers, including CRP (WMD: -0.58 mg/l, 95 % CI: -0.74, -0.41), TNF-α (WMD: -3.48 pg/ml, 95 % CI: -4.38, -2.58), and IL-6 (WMD: -1.31 pg/ml, 95 % CI: -1.58, -0.67); except for IL-1β (WMD: -0.46 pg/ml, 95 % CI: -1.18, 0.27) for which no significant change was found. Also, turmeric/curcumin supplementation significantly improved anti-oxidant activity through enhancing TAC (WMD = 0.21 mmol/l; 95 % CI: 0.08, 0.33), reducing MDA levels (WMD = -0.33 µmol /l; 95 % CI: -0.53, -0.12), and SOD activity (WMD = 20.51 u/l; 95 % CI: 7.35, 33.67). It seems that turmeric/curcumin supplementation might be used as a viable intervention for improving inflammatory/oxidative status of individuals.

Abstract
BACKGROUND Curcumin supplementation may promote weight loss and ameliorate obesity-related complications through its antioxidative and anti-inflammatory properties. OBJECTIVE An umbrella review and updated meta-analysis of randomized controlled trials (RCTs) was conducted to evaluate the effect of curcumin supplementation on anthropometric indices. METHODS Systematic reviews and meta-analyses (SRMAs) of RCTs were identified from electronic databases (Medline, Scopus, Cochrane, and Google Scholar) up to 31 March, 2022, without language restriction. SRMAs were included if they assessed curcumin supplementation on any of the following: BMI, body weight (BW), or waist circumference (WC). Subgroup analyses were performed, stratifying by patient types, severity of obesity, and curcumin formula. The study protocol was a priori registered. RESULTS From an umbrella review, 14 SRMAs with 39 individual RCTs were included with a high degree of overlap. In addition, searching was updated from the last search of included SRMAs in April 2021 up to 31 March, 2022, and we found 11 additional RCTs, bringing the total up to 50 RCTs included in the updated meta-analyses. Of these, 21 RCTs were deemed of high risk of bias. Curcumin supplementation significantly reduced BMI, BW, and WC with mean differences (MDs) of -0.24 kg/m2 (95% CI: -0.32, -0.16 kg/m2), -0.59 kg (95% CI: -0.81, -0.36 kg), and -1.32 cm (95% CI: -1.95, -0.69 cm), respectively. The bioavailability-enhanced form reduced BMI, BWs, and WC more, with MDs of -0.26 kg/m2 (95% CI: -0.38, -0.13 kg/m2), -0.80 kg (95% CI: -1.38, -0.23 kg) and -1.41 cm (95% CI: -2.24, -0.58 cm), respectively. Significant effects were also seen in subgroups of patients, especially in adults with obesity and diabetes. CONCLUSIONS Curcumin supplementation significantly reduces anthropometric indices, and bioavailability-enhanced formulas are preferred. Augmenting curcumin supplement with lifestyle modification should be an option for weight reduction. This trial was registered at PROSPERO as CRD42022321112 (https://www.crd.york.ac.uk/prospero/display_record.php?ID=CRD42022321112).

Effects of curcumin/turmeric supplementation on obesity indices and adipokines in adults: A grade-assessed systematic review and dose-response meta-analysis of randomized controlled trials. Phytother Res 2023; 37:1703-1728. [PMID: 36882287 DOI: 10.1002/ptr.7800] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/29/2022] [Revised: 02/11/2023] [Accepted: 02/22/2023] [Indexed: 03/09/2023]
Abstract
In the present study, we explored the effect of curcumin/turmeric supplementation on anthropometric indices of obesity, leptin, and adiponectin. We searched PubMed, Scopus, Web of Science, Cochrane Library, and Google Scholar up to August 2022. Randomized clinical trials (RCTs) investigating the impact of curcumin/turmeric on obesity indices and adipokines were included. We applied the Cochrane quality assessment tool to evaluate the risk of bias. The registration number is CRD42022350946. Sixty eligible RCTs, with a total sample size of 3691 individuals were included for quantitative analysis. We found that supplementation with curcumin/turmeric significantly reduced body weight (WMD: -0.82 kg, 95% CI: -1.30, -0.35; p = 0.001), body mass index (WMD: -0.30 kg/m2 , 95% CI: -0.53, -0.06, p = 0.013), waist circumference (WMD: -1.31 cm, 95% CI: -1.94, -0.69, p < 0.001), body fat percentage (WMD: -0.88%, 95% CI: -1.51, -0.25, p = 0.007), leptin (WMD = -4.46 ng/mL; 95% CI: -6.70, -2.21, p < 0.001), and increased adiponectin (WMD = 2.48 μg/mL; 95% CI: 1.34, 3.62, p < 0.001). Overall, our study shows that supplementation with curcumin/turmeric significantly improves anthropometric indices of obesity and adiposity-related adipokines (leptin and adiponectin). However, due to high between-studies heterogeneity, we should interpret the results with caution.

Abstract
Medicinal properties of turmeric (Curcuma longa L.), a plant used for centuries as an anti-inflammatory, are attributed to its polyphenolic curcuminoids, where curcumin predominates. Although "curcumin" supplements are a top-selling botanical with promising pre-clinical effects, questions remain regarding biological activity in humans. To address this, a scoping review was conducted to assess human clinical trials reporting oral curcumin effects on disease outcomes. Eight databases were searched using established guidelines, yielding 389 citations (from 9528 initial) that met inclusion criteria. Half focused on obesity-associated metabolic disorders (29%) or musculoskeletal disorders (17%), where inflammation is a key driver, and beneficial effects on clinical outcomes and/or biomarkers were reported for most citations (75%) in studies that were primarily double-blind, randomized, and placebo-controlled trials (77%, D-RCT). Citations for the next most studied disease categories (neurocognitive [11%] or gastrointestinal disorders [10%], or cancer [9%]), were far fewer in number and yielded mixed results depending on study quality and condition studied. Although additional research is needed, including systematic evaluation of diverse curcumin formulations and doses in larger D-RCT studies, the preponderance of current evidence for several highly studied diseases (e.g., metabolic syndrome, osteoarthritis), which are also clinically common, are suggestive of clinical benefits.

Abstract
BACKGROUND & AIMS The present systematic review and meta-analysis was conducted to investigate the effects of capsinoids on body mass index (BMI), body weight (BW), waist circumference (WC), waist-hip ratio (WHR), fat mass (FM), fat-free mass (FFM), visceral fat area (VFA), and percentage body fat (PBF). METHODS Four databases were searched from inception to November 2020 using relevant keywords. All clinical trials investigating the effects of capsinoids supplementation on body composition and anthropometric measures were retained. RESULTS Overall, 19 effect sizes and 13 trials with a total sample size of 838 participants were included. Capsinoids supplementation had no effect on BW (P = 0.230), BMI (P = 0.182), WC (P = 0.611), FM (P = 0.946), FFM (P = 0.917), WHR (P = 0.599), VFA (P = 0.836), and PBF (P = 0.973). Findings from subgroup analysis revealed a significant reduction in BW in trials conducted on overweight participants, and lasted ≥12 weeks, However, no significant non-linear associations were found between capsinoids supplementation dosage and study duration with both BW (For dosage: Pnon-linearity = 0.527, for duration: Pnon-linearity = 0.410) and BMI (For dosage: Pnon-linearity = 0.308, for duration: Pnon-linearity = 0.578). CONCLUSION Capsinoids supplementation has no significant effect on obesity indicators. However, capsinoids in trials conducted on overweight participants, and lasted ≥12 weeks may have a significant and modest reduction in BW. Well-designed RCTs with larger sample size and longer duration are needed to confirm these results.

Abstract
Turmeric, or Curcuma longa as it is formally named, is a multifunctional plant with numerous names. It was dubbed "the golden spice" and "Indian saffron" not only for its magnificent yellow color, but also for its culinary use. Turmeric has been utilized in traditional medicine since the dawn of mankind. Curcumin, demethoxycurcumin, and bisdemethoxycurcumin, which are all curcuminoids, make up turmeric. Although there have been significant advancements in cancer treatment, cancer death and incidence rates remain high. As a result, there is an increasing interest in discovering more effective and less hazardous cancer treatments. Curcumin is being researched for its anti-inflammatory, anti-cancer, anti-metabolic syndrome, neuroprotective, and antibacterial properties. Turmeric has long been used as a home remedy for coughs, sore throats, and other respiratory problems. As a result, turmeric and its compounds have the potential to be used in modern medicine to cure a variety of diseases. In this current review, we highlighted therapeutic potential of curcumin and its multiple health benefits on various diseases.

Abstract
Obesity is a global health problem needing urgent research. Synthetic anti-obesity drugs show side effects and variable effectiveness. Thus, there is a tendency to use natural compounds for the management of obesity. There is a considerable body of knowledge, supported by rigorous experimental data, that natural polyphenols, including curcumin, can be an effective and safer alternative for managing obesity. Curcumin is a is an important compound present in Curcuma longa L. rhizome. It is a lipophilic molecule that rapidly permeates cell membrane. Curcumin has been used as a pharmacological traditional medicinal agent in Ayurvedic medicine for ∼6000 years. This plant metabolite doubtless effectiveness has been reported through increasingly detailed in vitro, in vivo and clinical trials. Regarding its biological effects, multiple health-promoting, disease-preventing and even treatment attributes have been remarkably highlighted. This review documents the status of research on anti-obesity mechanisms and evaluates the effectiveness of curcumin for management of obesity. It summarizes different mechanisms of anti-obesity action, associated with the enzymes, energy expenditure, adipocyte differentiation, lipid metabolism, gut microbiota and anti-inflammatory potential of curcumin. However, there is still a need for systematic and targeted clinical studies before curcumin can be used as the mainstream therapy for managing obesity.

Abstract
Here, we presented new insights of the development of poly(lactic-co-glycolic acid) nanoparticles containing turmeric compounds (turmeric-PLGA-NPs) using emulsion-solvent evaporation method. The nanoparticulate system was characterized by size, zeta potential, morphology, release profile, partition parameter, stability and encapsulation efficiency (%EE). Antioxidant activity studies were also evaluated. The Korsmeyer-Peppas model (Mt/M∞ vs. t) was used to determine the release mechanisms of the studied system. Our results demonstrated the emulsion-solvent evaporation method was shown advantageous for producing turmeric-PLGA-NPs in the range of 145 nm with high homogeneity in size distribution, zeta potential of -21.8 mV and %EE about 72%. Nanoparticles were stable over a period of one month. In vitro study showed a release of curcumin governed by diffusion and relaxation of the polymeric matrix. The partition parameter of the extract in relation to blank-PLGA-NPs was 0.111 ± 0.008 M-1, indicating a low affinity of curcumin for the polymer matrix. Antioxidant ability of the turmeric-PLGA-NPs in scavenging the radical 2,2-azinobis (3-ethylbenzothiazoline- 6-sulfonic acid) (ABTS) was inferior to free turmeric extract and showed a concentration and time-dependent profile. The study concluded that PLGA nanoparticles are potential carriers for turmeric extract delivery.

Abstract
OBJECTIVE The present systematic review and meta-analysis were conducted to investigate the effects of capsinoids supplementation on glycaemic control. METHODS Relevant studies, published up to May 2020, were searched through PubMed/Medline, Scopus, ISI Web of Science, Embase and Google Scholar. All randomised clinical trials investigating the effect of capsinoids supplementation on glycaemic control were included. RESULTS Of 326 citations, eight trials with nine effect sizes that enrolled 530 subjects were included. Capsinoids and red pepper resulted in no significant reduction in glucose (Weighted mean differences (WMD): -0.27 mg/dL; 95% CI: -1.9 to 1.37, P = .75), insulin (WMD: -0.09 µU/mL; 95% CI: -1.76 to 1.57, P = .913), homeostatic model assessment for insulin resistance (HOMA-IR) (WMD: 0.52; 95% CI: -0.29 to 1.32, P = .208) and haemoglobin A1C (HbA1C) (WMD: 0.01%; 95% CI: -0.04 to 0.05, P = .712). Greater effects on glucose were detected in trials performed on both gender, using red pepper, lasted ≥12 weeks, and participants aged >40 years old and recruited greater sample size >50. Insulin and HOMA-IR were reduced by using red pepper. CONCLUSION Overall, these data suggest that capsinoids and red pepper supplementation did not have beneficial effects on glucose, insulin, HbA1C and HOMA-IR but significantly reduce glucose in people older than 40 years.

Abstract
Several studies have assessed the effect of red pepper on blood pressure (BP) and heart rate (HR) and reported controversial results. The aim of this study was to perform a systematic review and meta-analysis of clinical trials that evaluated the effect of red pepper/capsaicin consumption on BP and HR. Medline, Scopus, Cochrane Library, and Google Scholar were systematically searched, from database inception to August 2020, to ascertain clinical trials that evaluated the effects of red pepper or capsaicin on systolic blood pressure (SBP), diastolic blood pressure (DBP), or HR. Pooled effect size was calculated using a random-effects method. We performed subgroup analyses to discern probable sources of between-study heterogeneity. Meta-analysis showed no significant effect of red pepper/capsaicin on SBP (0.43 mmHg, 95% CI: -1.15 to 2.01), DBP (-0.45 mmHg, 95% CI: -2.14 to 1.24), and HR (-0.60 bpm, 95% CI: -1.97 to 0.78). Although between-study heterogeneity was high for SBP and DBP, we could not discern the potential sources of heterogeneity. In conclusion, red pepper/capsaicin had no effect on BP and HR. The findings should be interpreted with caution because between-study heterogeneity was high. Further well-designed and high-quality studies are required to investigate the efficacy and safety of red pepper/capsaicin supplement on BP and HR.

Abstract
It has been suggested that curcumin is a potential agent for lowering the levels of C-reactive protein (CRP) and high-sensitivity CRP (hs-CRP), as markers of inflammation. In the current meta-analysis, we attempted to clarify the efficacy of curcumin supplementation in lowering the concentrations of CRP and hs-CRP in patients with autoinflammatory conditions. Nine studies were found evaluating the effect of curcumin on CRP levels, while 23 studies were identified for hs-CRP. CRP concentration was decreased significantly compared to the placebo (WMD = -3.67 mg/L, 95% CI = -6.96 to -0.38, p = 0.02). There was a significant effect of curcumin at dose ≤1,000 mg/day on the CRP concentration. CRP concentration significantly decreased after >10-week intervention compared with placebo.hs-CRP concentration in the intervention group was significantly lower than that of placebo group. A significant effect of curcumin consumption was detected on the serum level of hs-CRP in studies with prescribing ≤1,000 mg/day, and those with ≤10-week duration of intervention. Curcumin consumption resulted in a reduction of hs-CRP in a non-linear fashion with stronger effects with less than 2000 mg curcumin per day. Curcumin seems to be beneficial in decreasing the hs-CRP and CRP levels in proinflammatory settings.

Abstract
Metabolomics is an important branch of systems biology, which can detect changes in the body's metabolism before and after the intervention of functional foods, identify effective metabolites, and predict the interventional effects and the mechanism. This review summarizes the latest research outcomes regarding interventional effects of functional foods on metabolic diseases via metabolomics analysis. Since metabolomics approaches are powerful strategies for revealing the changes in bioactive compounds of functional foods during processing and storage, we also discussed the effects of these parameters on functional food metabolites using metabolomics approaches. To date, a number of endogenous metabolites related to the metabolic diseases after functional foods intervention have been discovered. Unfortunately, the mechanisms of metabolic disease-related molecules are still unclear and require further studies. The combination of metabolomics with other omics technologies could further promote its ability to fully understand the precise biological processes of functional food intervention on metabolic diseases.

Front Pharmacol 2021; 12:659546. [PMID: 34276362 PMCID: PMC8278146 DOI: 10.3389/fphar.2021.659546] [Citation(s) in RCA: 13] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/27/2021] [Accepted: 05/24/2021] [Indexed: 01/05/2023] Open
Abstract
Background:Curcuma spp. (Zingiberaceae) are used as a spice and coloring agent. Their rhizomes and essential oils are known for medicinal properties, besides their use in the flavoring and cosmetic industry. Most of these biological activities were attributed to volatile and nonvolatile secondary metabolites present in the rhizomes of Curcuma spp. The metabolite variations among the species and even cultivars need to be established for optimized use of Curcuma spp. Objectives: We compared the phytochemical profiles of rhizomes and their essential oils to establish the variability among seven cultivars: five of Curcuma longa L. (Alleppey Supreme, Duggirala Red, Prathibha, Salem, Suguna) and two of C. aromatica Salisb. (Kasturi Araku, Kasturi Avidi). The GC-MS and LC-MS-based analyses were employed to profile secondary metabolites of these selected cultivars. Methods: Rhizomes of Curcuma spp. were subjected to hydro-distillation to collect essential oil and analyzed by GC-MS. The methanol extracts of fresh rhizomes were subjected to LC-MS analyses. The compounds were identified by using the relevant MS library databases as many compounds as possible. Results: The essential oil content of the cultivars was in the range of 0.74–1.62%. Several compounds were detected from the essential oils and rhizome extracts by GC-MS and LC-MS, respectively. Of these, 28 compounds (13 from GCMS and 15 from LCMS) were common in all seven cultivars, e.g., α-thujene, and diarylheptanoids like curcumin. Furthermore, a total of 39 new compounds were identified from C. longa L. and/or C. aromatica Salisb., most of them being cultivar-specific. Of these compounds, 35 were detected by GC-MS analyses of essential oils, 1,2-cyclohexanediol, 1-methyl-4-(1-methylethyl)-, and santolina alcohol, to name a few. The other four compounds were detected by LC-MS of the methanolic extracts of the rhizomes, e.g., kaempferol-3,7-O-dimethyl ether and 5,7,8-trihydroxy-2′,5′-dimethoxy-3′,4′-methylene dioxyisoflavanone. Conclusions: We identified and recorded the variability in the metabolite profiles of essential oils and whole rhizome extracts from the seven cultivars of Curcuma longa L. and C. aromatica Salisb. As many as 39 new metabolites were detected in these seven Indian cultivars of Curcuma spp. Many of these compounds have health benefits.

Abstract
Herbs and spices are recommended to increase flavor and displace salt in the diet. Accumulating evidence suggests herbs and spices may improve risk factors for cardiometabolic diseases. In this narrative review, an overview of evidence from human clinical trials examining the effect of herbs and spices on risk factors for cardiometabolic diseases is provided. Human clinical trials examining supplemental doses of individual spices and herbs, or the active compounds, have yielded some evidence showing improvements to lipid and lipoprotein levels, glycemic control, blood pressure, adiposity, inflammation, and oxidative stress. However, cautious interpretation is warranted because of methodological limitations and substantial between-trial heterogeneity in the findings. Evidence from acute studies suggests intake of mixed herbs and spices as part of a high-saturated fat, high-carbohydrate meal reduces postprandial metabolic impairments, including lipemia, oxidative stress, and endothelial dysfunction. Limited studies have examined the postprandial metabolic effects of incorporating mixed herbs and spices into healthy meals, and, to our knowledge, no trials have assessed the effect of longer-term intake of mixed herbs and spices on risk factors for cardiometabolic diseases. To inform evidence-based guidelines for intake of herbs and spices for general health and cardiometabolic disease risk reduction, rigorously conducted randomized controlled trials are needed, particularly trials examining herb and spice doses that can be incorporated into healthy dietary patterns.

[PMID: 33934954 DOI: 10.1016/j.cyto.2021.155541] [Citation(s) in RCA: 23] [Impact Index Per Article: 7.7] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/15/2021] [Revised: 03/27/2021] [Accepted: 04/09/2021] [Indexed: 12/23/2022]
Abstract
It has been suggested that curcumin has the potential for lowering inflammation. In the current meta-analysis, we attempted to clarify the efficacy of curcumin/turmeric supplementation in reducing concentrations of interleukin (IL)-1, IL-6, IL-8, and tumor necrosis factor (TNF)-α in patients with an inflammatory background. The main databases were searched to identify eligible trials evaluating the effect of curcumin in reducing IL-1, IL-6, IL-8, and TNF-α in serum up to March 2021. The effect sizes for weighted mean difference (WMD) and 95% confidence intervals (CI) were calculated. Overall, 32 randomized controlled trials (RCTs) were included. There was a significant decrease in the serum levels of IL-1 (WMD = -2.33 pg/ml, 95% CI = -3.33 to -1.34, P < 0.001) and TNF-α (WMD = -1.61 pg/ml, 95% CI = -2.72, -0.51, P < 0.001) compared to the placebo group following treatment. Nonetheless, curcumin/turmeric supplementation was non-significantly associated with reduced levels of IL-6 (WMD = -0.33 pg/ml, 95% CI = -0.99-0.34, P = 0.33) and increased levels of IL-8 (WMD = 0.52 pg/ml, 95% CI = -1.13-2.17, P = 0.53). The dose-responses analysis indicated that curcumin/turmeric supplementation resulted in IL-1 and IL-8 alteration in a non-linear model. Subgroup analysis according to duration and dose of treatment and target population revealed diverse outcomes. Curcumin could have a beneficial effect in reducing the proinflammatory cytokines IL-1 and TNF-α, but not IL-6 and IL-8 levels.

Abstract
Metabolomics of human biological fluids or tissues is used to discover markers for diseases by comparing the metabolome of the patients against healthy individuals. Ultimately, these markers can be used in drug discovery to determine how medications normalize (at least in part) the human metabolome at specific disease stages to homeostatic. Likewise, the health effects of food can be studied. Even metabolomics of the food can be combined with metabolomics of the treated patients to correlate compounds from food with measurable health effects from clinical studies. Various chemometric analyses of these metabolomics data are used to identify markers for diseases and to obtain evidence for health effects. This review discusses recent researches (published from 2013 to 2021) on whether specific dietary intervention to humans suffering from metabolic disorders may improve their pathological status. The scope is limited to those associated with major lifestyle diseases such as diabetes, obesity, and cardiovascular diseases, for which food is thought may have detrimental as well as beneficial effects on human health. It includes metabolites characterization of different biological samples such as the human serum/plasma, urine, saliva, feces, or ileal fluid. Whether the study results supported the claimed health benefits and whether the research was conducted with appropriate study design, was criticized.

Abstract
Over the past decades, the worldwide prevalence of obesity has dramatically increased, thus posing a serious public health threat. Obesity is associated with the development of comorbid conditions and psychological disorders. Several lifestyle interventions have been proposed to tackle obesity; however, long-term maintenance of these interventions often proves challenging. In addition, among the different types of diets there is still a debate about the optimal macronutrient composition that will achieve the best results in weight loss. Recently, several commonly used spices such as pepper, ginger, and curcumin have been shown to play a beneficial role in obesity management. Therefore, exploring the effects of certain herbs or dietary spices on obesity may be promising. Among these spices, curcumin, which is the primary component of the spice turmeric, has gained great interest for its multiple health benefits. Several randomized controlled trials have investigated the potential favorable effects of curcumin supplementation on anthropometric measures. The aim of this review is to evaluate the effect of curcumin supplementation on the anthropometric indices among overweight or obese adults.

Abstract
Chronic diseases are responsible for approximately 71% global deaths. These are characterized by chronic low-grade inflammation and metabolic alterations. "Functional foods" have been attributed with anti-inflammatory properties, demonstrated in cell lines and murine models; however, studies in humans are inconclusive. The purpose of this systematic review is to identify clinical trials that analyzed changes in inflammatory and metabolic mediators, in response to consumption of specific functional foods. A total of 3581 trials were screened and 88 were included for this review. Foods identified to regulate inflammation included cranberries, grapes, pomegranate, strawberries, wheat, whole grain products, low fat dairy products, yogurt, green tea, cardamom, turmeric, soy foods, almonds, chia seeds, flaxseed, pistachios, algae oil, flaxseed oil and grape seed oil. Clinical trials that focus on a dietary pattern rich in functional foods are necessary to explore if the additive effect of these foods lead to more clinically relevant outcomes.

Abstract
BACKGROUND & AIMS Animal studies have shown that capsaicin exerts beneficial effects on glucose metabolism. However, the findings of human studies are contradictory. Therefore, we aimed to conduct a systematic review and meta-analysis of controlled trials to assess the effect of capsaicin administration on glycemic indices. METHODS Medline, Scopus, Cochrane Library, and Google Scholar were searched from the database inception to January 14, 2021. The weighted (WMD) or standardized (SMD) mean difference with 95% confidence interval (CI) was calculated using a random-effects model. RESULTS Fourteen trials were included in this study. Long-term capsaicin supplementation did not show significant effects on fasting blood glucose (WMD: 0.03 mmol L-1, 95% CI: -0.05 to 0.12, I2 = 40.5%) and fasting insulin (SMD: 0.09, 95% CI: -0.04 to 0.22, I2 = 0.0%). Short-term capsaicin supplementation had no significant effects on 2-hour postprandial blood glucose (WMD: 0.06 mmol L-1, 95% CI: -0.34 to 0.47, I2 = 92.5%) and 2-hour postprandial insulin (WMD: 1.70 μIU mL-1, 95% CI: -3.46 to 6.86, I2 = 72.4%). Subgroup analysis revealed that the dose and ingestion form of capsaicin could be sources of between-study heterogeneity. CONCLUSIONS Capsaicin supplementation seems to have neither acute nor chronic beneficial or detrimental effects on blood glucose and insulin levels.

Abstract
CONTEXT Chronic inflammation is a major contributor to the development of noncommunicable diseases. Curcumin, a bioactive polyphenol from turmeric, is a well-known anti-inflammatory agent in preclinical research. Clinical evidence remains inconclusive because of discrepancies regarding optimal dosage, duration, and formulation of curcumin. OBJECTIVE The aim of this systematic review, conducted and reported in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines and checklist, was to evaluate the efficacy of curcumin supplementation on systemic inflammatory mediators, comparing dose, duration, and bioavailability status of interventions. DATA SOURCES The Medline, CINAHL, EMBASE, Scopus, and Cochrane literature databases were searched from 1980 to May-end 2019. Randomized controlled trials investigating effects of dietary curcumin on inflammatory mediators in humans not receiving anti-inflammatory treatment were eligible for inclusion. Two authors independently assessed titles and abstracts of identified articles for potential eligibility and respective, retrieved, full-text articles; disagreements were resolved by a third author. Evidence quality was critically appraised using the Quality Criteria Checklist for Primary Research. DATA EXTRACTION Thirty-two trials (N = 2,038 participants) were included and 28 were meta-analyzed using a random-effects model; effect sizes were expressed as Hedges' g (95%CI). DATA ANALYSIS Pooled data (reported here as weighted mean difference [WMD]; 95%CI) showed a reduction in C-reactive protein (-1.55 mg/L; -1.81 to -1.30), interleukin-6 (-1.69 pg/mL, -2.56 to -0.82), tumor necrosis factor α (-3.13 pg/mL; -4.62 to -1.64), IL-8 (-0.54 pg/mL; -0.82 to -0.28), monocyte chemoattractant protein-1 (-2.48 pg/mL; -3.96 to -1.00), and an increase in IL-10 (0.49 pg/mL; 0.10 to 0.88), with no effect on intracellular adhesion molecule-1. CONCLUSION These findings provide evidence for the anti-inflammatory effects of curcumin and support further investigation to confirm dose, duration, and formulation to optimize anti-inflammatory effects in humans with chronic inflammation.

Abstract
Metabolic syndrome (MetS) has increasingly gained importance as the main risk factor for cardiovascular diseases and type II diabetes mellitus. Various natural compounds derived from plants are associated with beneficial effects on the incidence and progression of MetS. This study aimed to evaluate the effects of Capsicum annuum on factors related to MetS by assessing randomized controlled trials (written in English). We searched the online databases of PubMed, Embase, Google scholar, and Cochrane Library up to April 2020. 'Patient/Population, Intervention, Comparison and Outcomes' format was used to determine whether intervention with C. annuum supplementation compared with placebo supplementation had any effect on the components of MetS among participants. We considered standardized mean differences (SMD) with 95% confidence intervals (CI) as effect size measures using random-effects model. Analysis of the included 11 studies (n = 609) showed that C. annuum supplementation had significant effect on low density lipoprotein-cholesterol [SMD = - 0.39; 95% CI - 0.72, - 0.07; P = 0.02; prediction interval, - 1.28 to 0.50] and marginally significant effect on body weight [SMD = - 0.19; 95% CI - 0.40, 0.03; P = 0.09]. However, larger and well-designed clinical trials are needed to investigate the effects of C. annuum on MetS.

[PMID: 33129596 DOI: 10.1016/j.clnu.2020.10.018] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/22/2020] [Revised: 10/10/2020] [Accepted: 10/13/2020] [Indexed: 10/23/2022]
Abstract
BACKGROUND & AIMS The present systematic review and meta-analysis were conducted to investigate the effects of capsinoids and fermented red pepper paste (FRPP) supplementation on Systolic Blood Pressure (SBP) and Diastolic Blood Pressure (DBP). METHODS Relevant studies, published up to May 2020, were searched through PubMed/Medline, Scopus, ISI Web of Science, Embase, and Google Scholar. All randomized clinical trials investigating the effect of capsinoids and FRPP supplementation on blood pressure including SBP and DBP were included. RESULTS Out of 335 citations, 7 trials that enrolled 363 subjects were included. Capsinoids and FRPP resulted in significant reduction in DBP (Weighted mean differences (WMD): -1.90 mmHg; 95% CI, -3.72 to -0.09, P = 0.04) but no significant change in SBP (WMD: 0.55 mmHg, 95% CI: -1.45, 2.55, P = 0.588). FRPP had a significant reduction in SBP. Greater effects on SBP were detected in trials, lasted ≥12 weeks, and sample size >50. Capsinoids with dosage ≤200 and FRPP with dosage of 11.9 g significantly decreased DBP. CONCLUSION Overall, these data suggest that supplementation with FRPP may play a role in improving SBP and DBP but for capsinoids no effects detected in this analysis on SBP and DBP.

Effects of Curcumin in a Mouse Model of Very High Fat Diet-Induced Obesity. Biomolecules 2020; 10:biom10101368. [PMID: 32992936 PMCID: PMC7650718 DOI: 10.3390/biom10101368] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/13/2020] [Revised: 09/10/2020] [Accepted: 09/18/2020] [Indexed: 02/08/2023] Open
Abstract
Worldwide rates of Western-diet-induced obesity epidemics are growing dramatically. Being linked with numerous comorbidities and complications, including cardiovascular disease, type 2 diabetes, cancer, chronic inflammation, and osteoarthritis (OA), obesity represents one of the most threatening challenges for modern healthcare. Mouse models are an invaluable tool for investigating the effects of diets and their bioactive components against high fat diet (HFD)-induced obesity and its comorbidities. During recent years, very high fat diets (VHFDs), providing 58–60% kcal fat, have become a popular alternative to more traditional HFDs, providing 40–45% total kcal fat, due to the faster induction of obesity and stronger metabolic responses. This project aims to investigate if the 60% fat VHFD is suitable to evaluate the protective effects of curcumin in diet-induced obesity and osteoarthritis. B6 male mice, prone to diet-induced metabolic dysfunction, were supplemented with VHFD without or with curcumin for 13 weeks. Under these experimental conditions, feeding mice a VHFD for 13 weeks did not result in expected robust manifestations of the targeted pathophysiologic conditions. Supplementing the diet with curcumin, in turn, protected the animals against obesity without significant changes in white adipocyte size, glucose clearance, and knee cartilage integrity. Additional research is needed to optimize diet composition, curcumin dosage, and duration of dietary interventions to establish the VHFD-induced obesity for evaluating the effects of curcumin on metabolic dysfunctions related to obesity and osteoarthritis.

Abstract
Nonalcoholic fatty liver disease (NAFLD) is a major cause of liver-related morbidity; its prevalence is elevating due to the rising epidemic of obesity. Several clinical trials have examined the effects of curcumin supplementation on anthropometric variables in NAFLD patients with inconclusive results. This dose-response meta-analysis aimed to evaluate the impact of curcumin supplementation on body mass index (BMI), body weight, and waist circumference (WC) in patients with NAFLD. A systematic review of the literature was conducted using PubMed/Medline, ISI Web of Science, Scopus, Cochrane Library, EMBASE, Google Scholar, Sid.ir, and Magiran.com to identify eligible studies up to March 2019. A meta-analysis of eligible studies was performed using the random-effects model to estimate the pooled effect size. Eight randomized controlled trials with 520 participants (curcumin group = 265 and placebo group = 255) were included. Supplementation dose and duration ranged from 70 to 3,000 mg/day and 8 to 12 weeks, respectively. Curcumin supplementation significantly reduced BMI (weighted mean difference [WMD] = -0.34 kg/m2 , 95% CI [-0.64, -0.04], p < .05) and WC (WMD = -2.12 cm, 95% CI [-3.26, -0.98], p < .001). However, no significant effects of curcumin supplementation on body weight were found. These results suggest that curcumin supplementation might have a positive effect on visceral fat and abdominal obesity that have been associated with NAFLD.

Abstract
INTRODUCTION Obesity is a disorder characterized by a disproportionate increase in body weight in relation to height, mainly due to the accumulation of fat, and is considered a pandemic of the present century by many international health institutions. It is associated with several non-communicable chronic diseases, namely, metabolic syndrome, type 2 diabetes mellitus (T2DM), cardiovascular diseases (CVD), and cancer. Metabolomics is a useful tool to evaluate changes in metabolites due to being overweight and obesity at the body fluid and cellular levels and to ascertain metabolic changes in metabolically unhealthy overweight and obese individuals (MUHO) compared to metabolically healthy individuals (MHO). OBJECTIVES We aimed to conduct a systematic review (SR) of human studies focused on identifying metabolomic signatures in obese individuals and obesity-related metabolic alterations, such as inflammation or oxidative stress. METHODS We reviewed the literature to identify studies investigating the metabolomics profile of human obesity and that were published up to May 7th, 2019 in SCOPUS and PubMed through an SR. The quality of reporting was evaluated using an adapted of QUADOMICS. RESULTS Thirty-three articles were included and classified according to four types of approaches. (i) studying the metabolic signature of obesity, (ii) studying the differential responses of obese and non-obese subjects to dietary challenges (iii) studies that used metabolomics to predict weight loss and aimed to assess the effects of weight loss interventions on the metabolomics profiles of overweight or obese human subjects (iv) articles that studied the effects of specific dietary patterns or dietary compounds on obesity-related metabolic alterations in humans. CONCLUSION The present SR provides state-of-the-art information about the use of metabolomics as an approach to understanding the dynamics of metabolic processes involved in human obesity and emphasizes metabolic signatures related to obesity phenotypes.

Abstract
Background and objective: The current systematic review and meta-analysis of randomized controlled trials (RCTs) was carried out to assess the influence of curcumin intake on weight among patients with metabolic syndrome and related disorders. Methods: We searched the following databases up until January 2018: MEDLINE, EMBASE, Web of Science, and Cochrane Central Register of Controlled Trials. The relevant data were extracted and evaluated for quality of the studies in accordance with the Cochrane risk of bias tool. Data were pooled using the inverse variance method and expressed as standardized mean difference (SMD) with 95% confidence intervals (95% CI). Results: Eighteen articles (21 studies) that comprised a total of 1,604 individuals were finally included in the meta-analysis. Curcumin intake significantly reduced body mass index (BMI) (SMD −0.37; 95% CI, −0.61, −0.13; P < 0.01), weight (SMD −0.23; 95% CI, −0.39, −0.06; P < 0.01), waist-circumference (WC) (SMD −0.25; 95% CI, −0.44, −0.05; P = 0.01), leptin levels (SMD −0.97; 95% CI, −1.18, −0.75; P < 0.001) and increased adiponectin levels (SMD 1.05; 95% CI, 0.23, 1.87; P = 0.01). We found no significant effect of curcumin intake on hip ratio (HR) (SMD −0.17; 95% CI, −0.42, 0.08; P = 0.18). Conclusions: Overall, we have found that curcumin intake among patients with metabolic syndrome and related disorders was correlated with a significant reduction in BMI, weight, WC, and leptin, and a significant increase in adiponectin levels, but did not affect HR.

Abstract
Turmeric extract or active component curcumin may have anti-inflammatory effects in people with chronic inflammatory diseases. The effect of turmeric or curcumin on a wide range of inflammatory markers has not been evaluated in a systematic review. We performed a systematic review of randomized controlled trials (RCTs) evaluating the effects of oral turmeric or curcumin on inflammatory markers (CRP, hsCRP, IL-1, IL-6, TNF) in patients with a wide range of chronic inflammatory diseases. Pubmed, EMBASE, Scopus, the Web of Science, and the Cochrane library were evaluated until June 2018. Random effects meta-analyses with inverse variance methods and stratified by turmeric or curcumin were performed. Effects were expressed as mean differences (MD) and their 95% confidence intervals (CI). Risk of bias of RCTs was evaluated with the Cochrane tool. Nineteen RCTs were identified; included patients had rheumatic diseases, advanced chronic kidney disease with hemodialysis, metabolic syndrome, and cardiovascular diseases. Turmeric was the intervention in 5 RCTs (n = 356) and curcumin/curcuminoids in 14 RCTs (n = 988). Follow up times ranged between 4 and 16 weeks. One RCT had high risk of bias. In comparison to controls, turmeric or curcumin did not significantly decrease levels of CRP (MD -2.71 mg/L, 95%CI -5.73 to 0.31, p = 0.08, 5 studies), hsCRP (MD -1.44 mg/L, 95%CI -2.94 to 0.06, p = 0.06, 6 studies), IL-1 beta (MD -4.25 pg/mL, 95%CI -13.32 to 4.82, p = 0.36, 2 studies), IL-6 (MD -0.71 pg/mL, 95%CI -1.68 to 0.25, p = 0.15), and TNF alpha (MD -1.23 pg/mL, 95%CI -3.01 to 0.55, p = 0.18, 7 studies). There were no differences between turmeric and curcumin interventions. High heterogeneity of effects was observed for all markers across studies, except hsCRP. Other inflammatory markers such as IL-1 alpha, TNF beta, IL-17, and IL-22 had scarce data. Turmeric or curcumin did not decrease several inflammatory markers in patients with chronic inflammatory diseases.

Abstract
: Hypertension is a major risk factor for cardiovascular disease, affecting 1 billion people worldwide. Literature suggests some herbs and spices have cardiovascular benefits, such as decreasing blood pressure; yet evidence is inconsistent. This article reviewed randomized controlled trials investigating effects of herbs and spices on blood pressure in normotensive, pre-hypertensive and hypertensive participants. Ovid Medline, Embase, Biological abstracts, CINAHL and Cochrane Collaboration were systematically searched. After inclusion and exclusion criteria were applied, nine articles were included for analysis. Overall, three of the nine studies reported statistically significant results, including one of the two studies on hypertensive participants and two of the six studies on pre-hypertensive participants. The remaining study was conducted on normotensive participants and reported no change in blood pressure. There is evidence to suggest certain herbs and spices can reduce blood pressure in a hypertensive and pre-hypertensive population and may not induce hypotension in a normotensive population.

Abstract
Diabetes mellitus is the most common metabolic disorder worldwide. This study examined the effect of turmeric supplementation on glycemic status, lipid profile, hs-CRP and total antioxidant capacity in hyperlipidemic type 2 diabetic patients. In this double-blind, randomized clinical trial, 80 hyperlipidemic type 2 diabetic patients were divided into turmeric (2,100 mg powdered rhizome of turmeric daily) and placebo groups for 8 weeks. Body weight, fasting plasma glucose, hemoglobin A1c (HbA1c), serum insulin, triglyceride (TG), total cholesterol, low density lypoprotein cholesterol (LDL-c), high density lypoprotein cholesterol, apolipoprotein A1, apolipoprotein B, high sensitivity C-reactive protein (hs-CRP), and total antioxidant capacity were measured before and after intervention. Statistical analysis was carried out using paired and independent t and chi-square tests. Seventy five patients completed the study. The turmeric group showed significant decreases in body weight, TG, and LDL-c compared with baseline (p value < 0.05). Body mass index, TG, and total cholesterol decreased significantly in the turmeric group compared with the placebo group (p value < 0.05). No significant changes were observed in other parameters between the two groups after intervention (p value < 0.05). Turmeric improved some fractions of lipid profile and decreased body weight in hyperlipidemic patients with type 2 diabetes. It had no significant effect on glycemic status, hs-CRP, and total antioxidant capacity in these patients.

Abstract
Curcuma longa L., its derived extracts and even its major compound curcumin has a long history of use and doubtless effectiveness, reported through increasingly detailed in vitro, ex vivo, in vivo and even clinical trials. Regarding its biological effects, multiple health-promoting, disease-preventing and even treatment attributes has been remarkably highlighted. Clinical trials, although have increased in a progressive manner, significant disproportionalities have been stated in terms of biological effects assessment. In this sense, the present report aims to provide an extensive overview to curcumin therapeutic effects in human subjects. For that, clinical trials assessing the curcumin effect on inflammation, skin, eye, central nervous system, respiratory, cardiovascular, gastrointestinal, urogenital and metabolic disorders are here presented and discussed. A special emphasis was also given to curcumin activity on intoxications and multiple malignant diseases.

[PMID: 30402990 DOI: 10.1002/ptr.6226] [Citation(s) in RCA: 75] [Impact Index Per Article: 12.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/29/2018] [Revised: 10/03/2018] [Accepted: 10/16/2018] [Indexed: 02/05/2023]
Abstract
Besides other benefits, curcumin is getting more recognized for its antioxidant and anti-inflammatory properties, highlighting the importance of curcumin application for chronic disease prevention. This systematic review and meta-analysis of randomized controlled trials (RCTs) was conducted to assess the influence of curcumin-containing supplements on biomarkers of inflammation and oxidative stress. MEDLINE, EMBASE, Web of Science, and Cochrane Central Register of Controlled Trials were searched till January 2018 for eligible studies. The selected studies were evaluated for their quality using the Cochrane risk of bias tool and relevant data were extracted from included studies. Data were pooled using the inverse variance method and expressed as standardized mean difference (SMD) with 95% confidence intervals (95% CI). Fifteen RCTs were included in the final analysis. The meta-analysis indicated that curcumin supplementation significantly decreased interleukin 6 (IL-6) (SMD -2.08; 95% CI [-3.90, -0.25]; p = 0.02), high-sensitivity C-reactive protein (hs-CRP) (SMD -0.65; 95% CI [-1.20, -0.10], p = 0.02), and malondialdehyde (MDA) concentrations (SMD -3.14; 95% CI [-4.76, -1.53], p < 0.001). Though, curcumin supplementation had no significant effect on tumor necrosis factor-alpha (SMD -1.62; 95% CI [-3.60, 0.36]; p = 0.10) and superoxide dismutase levels (SMD 0.34; 95% CI [-1.06, 1.74], p = 0.63). Overall, this meta-analysis suggests that taking curcumin-containing supplements may exert anti-inflammatory and antioxidant properties through a significant reduction in IL-6, hs-CRP, and MDA levels.

Abstract
Current research indicates curcumin [diferuloylmethane; a polyphenolic compound isolated from the rhizomes of the dietary spice turmeric (Curcuma longa)] exerts a beneficial effect on health which may be partly attributable to its anti-oxidative and anti-inflammatory properties. The aim of this review is to examine potential mechanisms of the actions of curcumin in both animal and human studies. Curcumin modulates relevant molecular target pathways to improve glucose and lipid metabolism, suppress inflammation, stimulate antioxidant enzymes, facilitate insulin signalling and reduce gut permeability. Curcumin also inhibits Aβ and tau accumulation in animal models and enhances mitochondria and synaptic function. In conclusion, in high-dose animal studies and in vitro, curcumin exerts a potential beneficial effect on cardiometabolic disease. However, human studies are relatively unconvincing. More intervention studies should be conducted with the new curcumin formulation with improved oral bioavailability.

Abstract
Functional foods can be effective in the prevention of metabolic syndrome and subsequently the onset of cardiovascular diseases and type II diabetes mellitus. More recently, however, another term was introduced to describe foods with additional health benefits: "superfoods", for which, to date, no generally accepted definition exists. Nonetheless, their consumption might contribute to the prevention of metabolic syndrome, for example due to the presence of potentially bioactive compounds. This review provides an overview of controlled human intervention studies with foods described as "superfoods" and their effects on metabolic syndrome parameters. First, an Internet search was performed to identify foods described as superfoods. For these superfoods, controlled human intervention trials were identified until April 2017 investigating the effects of superfood consumption on metabolic syndrome parameters: waist circumference or BMI, blood pressure, or concentrations of HDL cholesterol, triacylglycerol or glucose. Seventeen superfoods were identified, including a total of 113 intervention trials: blueberries (8 studies), cranberries (8), goji berries (3), strawberries (7), chili peppers (3), garlic (21), ginger (10), chia seed (5), flaxseed (22), quinoa (1), cocoa (16), maca (1), spirulina (7), wheatgrass (1), acai berries (0), hemp seed (0) and bee pollen (0). Overall, only limited evidence was found for the effects of the foods described as superfoods on metabolic syndrome parameters, since results were not consistent or the number of controlled intervention trials was limited. The inconsistencies might have been related to intervention-related factors, such as duration or dose. Furthermore, conclusions may be different if other health benefits are considered.

Abstract
Vascular endothelial dysfunction is a potential risk factor for cardiovascular disease. This study evaluated the effect of curcumin on factors associated with vascular dysfunction using rats fed a high-sucrose, high-fat (HSF) diet. The experiment included 2 animal feeding phases. In the first feeding phase, male Sprague–Dawley rats were randomly divided into 2 groups: the control group (n = 8) was fed a standard diet (AIN-93G) and the HSF group (n = 24) was fed an HSF diet for 8 weeks to induce obesity. In the second feeding phase, lasting 4 weeks, the HSF group was randomly divided into 3 subgroups: the O group (n = 8) continued feeding on the HSF diet, the OA group (n = 8) had the HSF diet replaced with AIN-93G, and the OC group (n = 8) was fed the HSF diet supplemented with curcumin (300 mg/kg body weight daily). After 8 weeks, the HSF diet significantly elevated levels of aspartate aminotransferase (AST), alanine aminotransferase (ALT), insulin, homeostatic model assessment insulin resistance (HOMA-IR), low-density lipoprotein cholesterol (LDL-C), homocysteine (Hcy), C-reactive protein (CRP), vascular cell adhesion molecule 1 (VCAM-1), and intercellular adhesion molecule 1 (ICAM-1) but significantly reduced levels of nitric oxide (NO) and high-density lipoprotein cholesterol (HDL-C). After dietary intervention, the OA and OC groups exhibited significantly lower levels of AST, ALT, HOMA-IR, cholesterol, LDL-C, Hcy, CRP, VCAM-1, and ICAM-1 and higher levels of NO and catalase (CAT) activity compared with the O group. Superoxide dismutase, CAT, and glutathione peroxidase activities were increased in the OA group, while CAT levels were enhanced in the OC group. In conclusion, this study showed that curcumin supplementation and diet modification can inhibit HSF diet-induced vascular dysfunction potentially by enhancing NO production and antioxidant enzyme activities, thereby suppressing inflammation and oxidative damage in the vascular endothelium.

Abstract
OBJECTIVE Curcumin is an active constituent of turmeric. Recently, scientists have suggested that curcumin can be used in weight reduction. We performed a systematic review based on randomized controlled trials to assess the effects of curcumin supplementation on anthropometric variables. METHODS We searched databases including PubMed, Embase, Web of Science, Scopus, and Google Scholar up to August 2017. Randomized clinical trials assessing the effects of curcumin on anthropometric parameters in human adults were included. RESULT Eight randomized clinical trials were allowed to be included in the systematic review. Five articles used the regular form of curcumin with short follow-up duration and did not indicate any significant effect on anthropometric measures, while three articles with significant results used either the more bioavailable form of curcumin or a longer intervention duration. CONCLUSION Randomized clinical trials related to curcumin effect on weight are limited but their result indicated useful effect of curcumin on weight. It seems that the bioavailable form of curcumin can reduce obesity and overweight. Further articles with longer duration of intervention and different forms of curcumin supplementation are necessary before any recommendation is made for clinical use of these interventions.

Clustering according to urolithin metabotype explains the interindividual variability in the improvement of cardiovascular risk biomarkers in overweight-obese individuals consuming pomegranate: A randomized clinical trial. Mol Nutr Food Res 2017; 61.

Abstract
SCOPE The pomegranate lipid-lowering properties remain controversial, probably due to the interindividual variability in polyphenol (ellagitannins) metabolism. OBJECTIVE We aimed at investigating whether the microbially derived ellagitannin-metabolizing phenotypes, i.e. urolithin metabotypes A, (UM-A), B (UM-B), and 0 (UM-0), influence the effects of pomegranate extract (PE) consumption on 18 cardiovascular risk biomarkers in healthy overweight-obese individuals. METHODS AND RESULTS A double-blind, crossover, dose-response, randomized, placebo-controlled trial was conducted. The study (POMEcardio) consisted of two test phases (dose-1 and dose-2, lasting 3 weeks each) and a 3-week washout period between each phase. Forty-nine participants (BMI > 27 kg/m2 ) daily consumed one (dose-1, 160 mg phenolics/day) or four (dose-2, 640 mg phenolics/day) PE or placebo capsules. Notably, UM-B individuals showed the highest baseline cardiovascular risk. After dose-2, total cholesterol (-15.5 ± 3.7%), LDL-cholesterol (-14.9 ± 2.1%), small LDL-cholesterol (-47 ± 7%), non-HDL-cholesterol (-11.3 ± 2.5%), apolipoprotein-B (-12 ± 2.2%), and oxidized LDL-cholesterol -24 ± 2.5%) dose dependently decreased (P < 0.05) but only in UM-B subjects. These effects were partially correlated with urolithin production and the increase in Gordonibacter levels. Three (50%) nonproducers (UM-0) became producers following PE consumption. CONCLUSIONS UM clustering suggests a personalized effect of ellagitannin-containing foods and could explain the controversial pomegranate benefits. Research on the specific role of urolithins and the microbiota associated with each UM is warranted.

Abstract
Curcumin, when administered in a bioavailable form, has potential to influence vascular health of various populations, leading to decreases in cardiovascular disease risk. Clinical intervention studies with curcumin have demonstrated significant improvements in endothelial function, arterial compliance, arterial stiffness, and other measures of vascular hemodynamics in young, middle-aged, old, post-menopausal, healthy, diabetic, and obese individuals. Mechanistically, curcumin is believed to improve vascular function through its effects on inflammation, oxidative stress, nitric oxide bioavailability, and structural proteins of the artery. Current data give support for curcumin to be administered for improvements in vascular health to individuals that may or may not be at risk for cardiovascular disease. This review briefly summarizes the techniques used for the establishment of vascular health and overviews the literature investigating the role of curcumin in the improvement of vascular health.

Abstract
Curcumin, a plant-derived polyphenolic compound, naturally present in turmeric (Curcuma longa), has been the subject of intensive investigations on account of its various activities. The implementation of safe, beneficial and highly functional compounds from natural sources in human nutrition/prevention/therapy requires some modifications in order to achieve their multi-functionality, improve their bioavailability and delivery strategies, with the main aim to enhance their effectiveness. The low aqueous solubility of curcumin, its rapid metabolism and elimination from the body, and consequently, poor bioavailability, constitute major obstacles to its application. The main objectives of this review are related to reported strategies to overcome these limitations and, thereby, improve the solubility, stability and bioavailability of curcumin. The effectiveness of curcumin could be greatly improved by using nanoparticle-based carriers. The significance of the quality of a substance delivery system is reflected in the fact that carrying curcumin as a food additive/nutrition also means carrying the active biological product/drug. This review summarizes the state of the art, and highlights some examples and the most significant advances in the field of curcumin research.
