To compare the effect of insulin sensitizing drugs (metformin and rosiglitazone) over glucose homeostasis (GH) in no diabetic metabolic syndrome individuals. A randomized blinded clinical trial did in patients with metabolic syndrome (n=30), without diabetes. Prior to detailed information and signature of informed consent by patients were done three treatment groups by randomized technique; a) Placebo, b) Metformin (850 mg/day), c) Rosiglitazone (4 mg/day), treatment was administered for 8 weeks. GH was measured before and after treatment using oral glucose tolerance test (OGTT), and IR-index (Homeostatic Model). Determination was performed on weight, size, body mass index, plicometry, blood pressure, fasting glucose levels, triglycerides, HDL-cholesterol and insulin.

Previous work of the investigators demonstrated the anti-obesity and anti-steatosis potential of the Amazonian fruit camu-camu (CC) in a mouse model of diet-induced obesity [1]. It was demonstrated that the prebiotic role of CC was directly linked to higher energy expenditure stimulated by the fruit since fecal transplantation from CC-treated mice to germ-free mice was sufficient to reproduce the effects. The full protection against hepatic steatosis observed in CC-treated mice is of particular importance since nonalcoholic fatty liver disease (NAFLD) is one of the most common causes of chronic liver disease. Thirty percent of adults in developed countries have excess fat accumulation in the liver, and this figure can be as high as 80% in obese subjects. NAFLD is an umbrella term encompassing simple steatosis, as well as non-alcoholic steatohepatitis which can lead to cirrhosis and hepatocellular carcinoma in up to 20% of cases. Up to now, except for lifestyle changes, no effective drug treatment are available. Previous work has suggested that CC possesses anti-inflammatory properties and could acutely reduce blood pressure and glycemia after a single intake. While CC could represent a promising treatment for obesity and fatty liver, no studies have thoroughly tested this potential in humans. Therefore, a robust clinical proof of concept study is needed to provide convincing evidence for a microbiome-based therapeutic strategy to counteract obesity and its associated metabolic disorders. The mechanism of action of CC could involve bile acid (BA) metabolism. BA are produced in the liver and metabolized in the intestine by the gut microbiota. Conversely, they can modulate gut microbial composition. BA and particularly, primary BA, are powerful regulators of metabolism. Indeed, mice treated orally with the primary BA α, β muricholic (αMCA, βMCA) and cholic acids (CA) were protected from diet-induced obesity and hepatic lipid accumulation. Interestingly, the investigators reported that administration of CC to mice increased the levels of αMCA, βMCA and CA. Primary BA are predominantly secreted conjugated to amino acids and that deconjugation rely on the microbial enzymatic machinery of gut commensals. The increased presence of the deconjugated primary BA in CC-treated mice indicate that a cluster of microbes selected by CC influence the BA pool composition. These data therefore point to an Interplay between BA and gut microbiota mediating the health effects of CC. Polyphenols and in particular procyanidins and ellagitannins in CC can also be responsible for the modulation of BA that can impact on the gut microbiota. Indeed, it has been reported that ellagitannins containing food like walnuts modulate secondary BA in humans whereas procyanidins can interact with farnesoid X receptors and alter BA recirculation to reduce hypertriglyceridemia. These effects are likely mediated by the remodeling of the microbiota by the polyphenols. In accordance with the hypothesis that the ultimate effect of CC is directly linked to a modification of the microbiota, fecal transplantation from CC-treated mice to germ-free mice was sufficient to recapitulate the lower weight gain and the higher energy expenditure seen in donor mice.
The overall goal of this project is to determine the inflammation lowering impact of anthocyanin-rich Aronia berries. Inflammation is an underlying mechanism driving the development of several diseases. While an elevation in immune signals in the systemic circulation is commonly attributed to adipose tissue, inflammation is not present in all obese individuals. Adipose tissue must become inflamed, and the inflammation trigger may come from other sources. Microorganisms (microbiome), host tissues, and immune cells residing in the gastrointestinal tract (GIT) are a key source of pro-inflammatory signals that may cause the host organism to become inflamed. Anthocyanins are bioactive compounds with established anti-inflammatory and microbiome altering properties. We hypothesize that the GIT microbiome is a key determinant of host inflammation than can be manipulated by anthocyanins-rich berries to lower inflammation. We assembled a cohort of individuals, characterized their GIT microbiome and performed anthropometric measurements, basal measures of metabolism and metabolic health, and triglyceridemic, metabolomic, and inflammation responses to a high-fat meal challenge.
Our goal is to determine how the addition of sugar-sweetened beverages to the diet affects glucose control, cardiovascular disease risk factors, and pulmonary function in healthy, young adults.
It has been suggested that the actual obesity epidemy is related to chronic overconsumption of added or free sugars. The increasing popularity of artificial sweeteners attest the population willingness to reduce added sugars intake and to use alternatives to alleviate health impact of free sugar overconsumption. However, recent findings suggest that artificial sweeteners may rather contribute to obesity epidemy and its associated adverse health effects, potentially via a negative impact on gut microbiota. It has been shown in various studies that, for the same amount of sucrose, unrefined sugars (such as maple syrup) are associated with favorable metabolic effects. The polyphenols contained in maple syrup, especially lignans, could contribute to these positive effects. Indeed, the strong impact of those biomolecules on the modulation of gut microbiota and on gastro-intestinal and metabolic health has been demonstrated in several studies. It is therefore highly relevant to test the hypothesis that the substitution of refined sugar by an equivalent amount of maple syrup (5% of daily energy intake) result in a lesser metabolic deterioration, by the modulation of maple syrup on gut microbiota, than the one observed with refined sugar.
A randomized, double blind sham controlled clinical trial to evaluate the efficacy of vestibular nerve stimulation (VeNS), together with a lifestyle modification program, compared to a sham control with a lifestyle modification programme, as a means of reducing excess body weight and body fat.
There is evidence that genistein present in soy can improve insulin resistance in rodents and humans with metabolic syndrome (MetS). However, it is not known if this improvement is associated with changes in the gut microbiota. In the present study, the investigators show that the consumption of genistein for 2 months could have an effect on insulin resistance in subjects with MetS. This effect will be accompanied by a modification of the gut microbiota taxonomy. As a consequence, there will be a reduction in metabolic endotoxemia accompanied by an increase in AMP-activated protein kinase (AMPK) phosphorylation and the expression of genes of fatty acid oxidation in skeletal muscle.
Obesity, characterized by an increase in body weight that results in excessive fat accumulation, is a global health problem. Recently, it has also been shown that obesity is associated with low-grade chronic systemic inflammation in adipose tissue. This condition is mediated by activation of the innate immune system in adipose tissue that promotes inflammation and oxidative stress and triggers a systemic acute-phase response. Previous research points towards the potential of phytochemicals in food as part of nutritional strategies for the prevention of obesity and associated inflammation, as well as, increase in insulin sensitivity in diabetic patients. In addition, there is strong evidence that obesity is inversely associated with vitamin D levels. The major cause of vitamin D deficiency in humans is the lack of adequate sun exposure. Unfortunately, very few foods, i.e. mushrooms, naturally contain vitamin D and foods that are fortified with vitamin D are inadequate to satisfy vitamin D requirements. The last decade, mushrooms have attracted the research interest as functional foods with desirable health benefits in several metabolic disorders without the side effects of pharmacological treatment. Edible mushrooms are highly nutritious and exhibit beneficial effects on several inflammatory diseases such as cancer, heart disease, diabetes,, high blood pressure. Thus, the purpose of this study is to determine the effects of nutritious mushrooms in adults with Metabolic Syndrome. More specifically, 100 participants will be allocated to two groups, namely intervention group (N=50) and control group (N=50). Vitamin D2-enhanced mushrooms by UV-B will be provided as a snack to the intervention group, whereas the control group will not consume the snack. The intervention will last 3 months.The effects of the intervention will be evaluated via clinical and laboratory markers. Personal and family history, anthropometric, demographic data, body composition, dietary habits, physical activity and smoking status will be assessed pre- and post- intervention. Biochemical profile, oxidative stress and inflammation, as well as metabolomic profiles will be assessed in blood samples pre- and post- intervention. Both groups will receive standard nutritional counselling throughout the intervention and will be encouraged to report any adverse effects they may experience during the intervention.
