Some recent study also found that mucilaginous fiber binds with PFAS the same way that it binds with cholesterol to keep the body from absorbing it. PFAS already in your system is believed to be reintroduced to your digestive system through bile excretion, some binds with the fiber and leaves your system, the rest is absorbed.

If you don’t eat a lot of food with mucilage, the main ingredient in Metamucil has mucilaginous fiber, as the name suggests.

The study author in the interview I read emphasized it wasn’t like ‘take fiber for a few months and PFAS is all gone,’ she and her husband just incorporated a mucilage supplement into their diets because of how prevalent it is in the environment.
