A Canadian clinical study analyzed serum samples from 72 male participants in Toronto to assess the levels of per- and polyfluoroalkyl substances (PFAS) in their blood. The study also investigated the impact of an oat fiber supplement on reducing these concentrations. The results showed that men commonly carry detectable levels of various PFAS and that the oat beta-glucan fiber supplement led to a significant reduction in PFAS concentrations, particularly PFOA and PFOS. Higher PFAS levels were associated with elevated liver enzymes, and the study suggested that longer studies are needed to determine the effectiveness of dietary fiber in lowering PFAS body burden.
