Dietary Yeast Trains Immune System to Fight Cancer in Mice

Researchers at Trinity College Dublin and University College Dublin found that a common dietary yeast beta-glucan supplement reprograms early bone marrow immune cells to create trained immunity that strengthens anti-tumor responses against colorectal, skin, and breast cancers in obese mice and can reverse obesity-related immune memory defects after weight loss; since Wellmune is already food-grade, this could accelerate human trials to test dietary supplementation alongside cancer therapies.
