This study aims to investigate the impact of replacing meat consumption with plant-based meat alternative consumption on cardiovascular health, the gut microbiome, and metabolic status.
Gut microbiota may play a key role in many metabolic diseases, including type 2 diabetes (T2D). Consumption of high-fat/high-sugar western diet seem to alter human resident microbiota towards reduced genetic diversity and to influence its metabolic activity towards enhanced energy extraction. Plant-based diets are effective in the treatment of T2D but it is not clear whether their effect results solely from diet composition or whether it is mediated, at least partly, by different microbiota and its metabolic activity. One possible therapeutic approach is replacement of "pro-diabetic" microbiota with its "healthy" variant but what the "healthy" microbiota is and under which conditions this microbiota could stay stable and functional is not known. The aim of the proposed study is to identify possible metagenome/metabolome characteristics in different human cohorts (T2D vs vegans), to assess the stability of vegan microbiota in T2D-like environment and to evaluate the possibility to influence human T2D microbiota/metabolome towards more protective composition by dietary intervention.
An individual's immune and metabolic status is coupled to consumed carbohydrates. Complex carbohydrates that are not digested by human enzymes may influence host biology by impacting microbiota composition and function, or act in a yet-unknown microbiota-independent manner. Prebiotics offer a promising safe route to influence host health, possibly via the microbiota. However, it remains largely unknown to what extent immune function and metabolism can be modulated by prebiotics.
This study tests the effectiveness of dietary interventions that have the possibility to improve markers of gut health and improve general well-being. This study will allow healthcare professionals to learn how dietary interventions involving fasting can affect health. Food is increasingly recognized as a core component of preventive and ameliorative health care. Juice fasting has quickly become one of the most popular self-prescribed dietary interventions in the United States. A wide variety of juice fasts are available in the popular market; a popular variation is the three-day juice fast. The purpose of this study is to assess the effects of a three-day juice fast on certain markers of age-related disease and bio-markers of longevity. In particular, this study will assess certain epigenetic markers, which measure how the environment (including diet) can change the way that genes are expressed without changing the genes themselves. The study will also assess the microbiome, and inflammatory and glycemic markers.
Cosmeceuticals are an emerging market within dermatology and the growth of natural products and derivatives of natural products has accelerated in use within the field. Here the investigators aimed to study the microbial and cosmetic effects of Synoxyl AZ, the trade name for topical acetyl zingerone (AZ), a novel compound designed based on Zingerone and curcumin.
This study is to assess the impact of two skincare regimens on the cutaneous microbiome and skin physiology of healthy male and female infants, ages 3-6 months using clinical, instrumental, D-Squame tape, microbiome and parental assessments over a five-week period.
The objectives of this study are to examine fecal bacterial population(s) and plasma cholesterol levels elicited by 40g of Oats and Cream of Rice over 6 weeks.
Morbid obesity leads to non-alcoholic fatty liver disease (NAFLD), and not all NAFLD cases benefit from weight loss e.g. after bariatric surgery. Our aim is to find out, which intrahepatic factors and / or biomarkers might be beneficial or can be identified as prognostic factors for remission of NAFLD after weight loss. As other factors such as the microbiome or muscle and fatty tissue also influence the development of obesity and liver diseases, it is planned to examine these parameters before and after bariatric surgery as well. Tissue biopsies will therefore be taken during the surgery, and blood as well as stool samples will be collected and compared for suitable biomarkers before and after the intervention.
The primary objective is to contrast the degree to which increased consumption of dietary fiber vs. fermented food can decrease inflammation, increase microbiota diversity and can impact microbiota production of short-chain fatty acids (SCFA), potential normalizers of metabolic and immune dysfunction, in obese and non-obese adults.
