Brief Summary:
A huge body of scientific evidence has suggested that xanthohumol (XAN) consumption, a polyphenol present in beer, has a positive effect on energy metabolism. This compound is known for its antioxidant, anti-inflammatory and anti-cancer properties which confer potential to be used as a food supplement. Nevertheless, XAN lipophilic properties prevent the extensive use of this molecule as a functional food compound. The company TA-XAN S.A.M. (Wiesbaden, Germany) has patented a method to overcome this solubility problem. So, the main aim of this study is to evaluate the effects of XAN consumption on metabolic syndrome progression in individuals recently diagnosed.
