About this study

Plant (poly)phenols is what we call a large number of substances that are produced by plants as secondary plant metabolites, which means substances that are not used for their growth and development but are necessary for them to survive. (Poly)phenols are divided in two major groups, flavonoids, and non-flavonoids, and each group contains a varied set of subgroups and substances. They are widely spread in fruit and vegetables that are part of the human diet, and, in general, studies have attributed many biological effects to the ingestion of (poly)phenols, especially in the prevention of non-communicable diseases. For this reason, research aims to understand their role in the health benefits of a diet that is rich in fruits and vegetables. When ingested, (poly)phenols are digested by both the human organism and the gut microbiota and are broken down into several smaller substances (catabolites) that are called low-molecular weight (poly)phenols (LMWP). Most of the absorbed (poly)phenols that reach our bloodstream and organs are LMWP. For the proposed study, 30 healthy adults will be recruited and, if considered able to participate, will follow a standardized diet that is restricted in (poly)phenol intake and will be randomly divided into two groups: one will receive a known source of (poly)phenols (coffee) and the other will receive water, keeping the restriction of (poly)phenol from the diet. The duration of one phase is 4 days + 12 hours, during which urine, feces, and sal…
