Phytochemicals, Molecular Mechanisms and Health (PHYTOBIOMOL)

Description

Objetives

The aim of the group is studying the molecular mechanism of action of food phytochemicals, mainly phenolic compounds and their metabolites, and the potential effect on health and in the prevention of highly prevalent chronic diseases related to oxidative stress and inflammation. The interest of the group also includes the study of the benefits of these compounds on the intestinal microbiome and on the metabolome. These investigations are developed as a holystic approach to evaluate the biological actions and the molecular mechanisms of action of the components by using celullar in vitro studies and preclinical animal models, as well as human clinical trials to verify the real effect of food intake on human health.
