Immune system Quote by Michael Greger
““Another option for athletes who want to sustain their immune function is nutritional yeast. A 2013 study reported that you may more effectively maintain your levels of white blood cells after exercise by consuming a special type of fibre found in baker’s, brewer’s, and nutritional yeast.67 Brewer’s yeast is bitter, but nutritional yeast has a pleasant, cheese-like flavor. It tastes particularly good on popcorn. The study found that after two hours of intense cycling, the number of monocytes (another type of immune system white blood cell) in subjects’ bloodstreams took a dip. But those who were given the equivalent of about three-quarters of a teaspoon of nutritional yeast before they exercised ended up with even higher levels of monocytes than when they started working out.68””
