Filter by:This study evaluates dietary green tea extract to improve gut health and inflammation in persons with metabolic syndrome and healthy adults. Participants will complete two phases of intervention in random order in which they will consume green tea extract or placebo for one month and then switch to the opposite treatment for an additional month.
The composition of a food or a meal consumed plays an important role in the rate of postprandial endocrine and metabolic response, especially if high in fats, sugars and total energy content and a reduction in its entity is related to beneficial effects towards the prevention of several chronical diseases. The physiological postprandial response depends on several factors, both intrinsic, such as natural characteristic of food, and extrinsic, such as the way in which food is processed. This study aims at investigating postprandial hormonal, metabolic, oxidative stress, inflammation and endotoxaemia responses after the consumption of different commercial confectionary products made with different reformulation (ingredients and/or processing techniques).The principal scope of the study is to evaluate the impact of the reformulation of different snacks on postprandial responses. The investigators therefore designed a randomized controlled crossover trial, in which 15 healthy volunteers will consume different isocaloric confectionary products (snacks) and their related reformulation (total products number = 6) and a reference snack. Venous blood samples will be collected until 4-h after meal consumption. In order to evaluate postprandial hormonal, metabolic, oxidative stress, inflammation and endotoxaemia responses several markers will be evaluate: - metabolic substrates: glucose; Triglycerides and NEFA; - hormones: insulin; c-peptide; GLP-1, GIP, leptin, ghrelin, PYY; - markers of inflammation: IL-6, IL-8, IL-10, IL-17, TNF-α, hsCRP, MCP-1; - markers of oxidative stress and antioxidant capacity: GSH, FRAP; - endotoxaemia: lipopolysaccharides (LPS). These results will contribute to a detailed evaluation of the effects of reformulation on physiological events after meal consumption, leading to clarify if these variations in ingredients and/or processing techniques can modify postprandial responses, making them more similar to those originated from the reference snack.
In spite of the growing evidence for the beneficial effects of probiotics, their anti-obesity effects are not well examined. No previous studies were conducted in this research area in the UAE. Hence, the aims of this study are to 1) Investigate the link between metabolic derangements associated with obesity and levels of LPS and LBP; 2) Study the relatedness of low grade inflammation with the ME; 3) Investigate the food intake assessment; and 4) Investigate the effectiveness of probiotics supplement on the obesity, ME and inflammation. This project will have two phases: 1) a cross-sectional, in which 250 adults will be recruited for the collection of anthropometric measures, food intake, and fasting blood samples to measure serum LPS, LBP, Lipid profile, IR, insulin-like growth factor, hs-CRP, IL-6, and glucose. 2) Intervention phase, in which 50 overweight subjects will be randomly assigned to either receive a daily probiotic (25 subjects) or a placebo capsule (25 subjects) during the intervention period.
Metabolic syndrome (MetS) adults (n = 24; 18-65 y) will be enrolled to complete a 2-arm, double-blind, randomized controlled, crossover trial. They will be randomized in 4-unit blocks to receive, for 14 d, a controlled diet with dairy milk (3.5% fat; 3 servings/d) enriched with milk fat globule membrane (MFGM, MEB) or a matched dairy milk that instead contains soy lecithin/phospholipid (control, COMP). All foods during each study period will be provided to ensure weight maintenance and to increase homogeneity of gut and host responses. Anthropometrics and blood pressure will be assessed at days 0, 7, and 14. Prior to (day 0) and after each 2-wk arm (day 14), a fasting blood sample will be collected to assess serum endotoxin and metabolic chemistries (glucose, lipids, insulin), and Toll-like receptor 4 /nuclear factor kappaB (TLR4/NFκB)-dependent genes from whole blood. A breath sample will be collected to assess the correlation analysis of plasma metabolic biomarkers. After the 2-week intervention, from fecal samples collected on day 13, the investigators will assess microbiota composition and function, short chain fatty acids (SCFA), and intestinal inflammatory markers (calprotectin, myeloperoxidase). On d 14, participants in the fasted state will receive a high-fat/high-glucose meal challenge to induce gut-derived endotoxin translocation. At 30-minute intervals for 3-hour, the investigators will evaluate circulating endotoxin, glucose, and insulin; TLR4/NFκB-dependent genes will be assessed from whole blood at 0 hour and 3-hour. Gut permeability probes will be co-administered with the test meal challenge, and 24-hour urine will be collected to assess gut barrier integrity. Participants will then undergo a 2-week washout prior to receiving the alternative treatment and completing all procedures in an identical manner.
The growing prevalence of obesity and type 2 diabetes (T2D) is a major public health problem. Recent studies have clearly established that the gut microbiota plays a key role in the investigator's propensity to develop obesity and associated metabolic health disorders. The gut microbiota compositions plays a decisive role in glucose metabolism and the chronic inflammatory state associated with insulin resistance. Consuming prebiotic rich diet, including polyphenol and inulin rich food could help modulate favorably the gut microbiota which could lead to a reduction of endotoxemia and beneficial metabolic health effects.
It is of major importance to refine prevention strategies in order to alleviate inflammation, insulin resistance and metabolic syndrome and it appear that improving gut health and microbiota represent a promising strategy. Cranberry-enriched diets may help prevent metabolic syndrome and its associated chronic diseases by a protective effect of gut health and microbiota. It is therefore highly relevant to test the hypothesis that a whole cranberry powder supplements (which include a mixture of polyphenols, free and fiber-associated proanthocyanidins, and fruits fibers) is associated with changes on the gut health and microbiota playing a major role in alleviating inflammation and obesity-associated metabolic disorders.
The objectives of this study are to examine the effects of ethnicity, central obesity and dietary components, on the human gut microbiome. The investigators hypothesize that these factors have an influence on the composition of the gut microbiome. Healthy subjects (n=35) provided stool samples for gut microbiome profiling using 16S rRNA sequencing and completed a dietary questionnaire. The serum samples were assayed for a panel of inflammatory cytokines. Their associations with central obesity were examined.
The aim of the present study is to determine the effect of monosaccharides on intestinal barrier function in healthy subjects.
Chronic diseases such as diabetes, cardiovascular diseases and cancer are a major burden on the Scottish population. Obesity and inflammation have strong links to these diseases. One of the mechanisms explaining the relationship between low-grade inflammation and excess weight is "endotoxaemia". We wish to study this phenomenon, when small components coming from our gut bacteria can pass into the bloodstream, raising the body's defences. Diet can modulate endotoxaemia. In this study, we propose to use curcumin, in a capsule form, to modulate endotoxaemia. Curcumin comes from turmeric, which is widely used as a spice. In this study, we want to test the effect of consuming curcumin extract to the composition of the gut microbiota, post-meal endotoxaemia, and inflammatory markers in blood.
This study compares three different protein supplements (casein, whey and leucine-enriched whey) and their effect on post-inflammatory muscle waste in a model of acute disease. Each test person will undergo all three interventions. It is believed that leucine is the primary driver of muscle protein synthesis and therefore we hypothesize that leucine-enriched whey and whey are superior to casein in combating post-inflammatory muscle waste, because of its higher leucine content (16%, 11% and 9% leucine, respectively).
