Through immune system support, brewer’s yeast can stop Clostridium difficile, a type of bacterium, from invading the body. It can also prevent E. coli and salmonella from making people ill. In those who contract salmonella, brewer’s yeast helps improve liver function, enabling the body to more quickly and effectively remove the infection from the bloodstream. Researchers have studied this phenomenon and discovered that brewer’s yeast acts both on a systemic and local level to help boost the immune system and heal the infection.
