What does blood type have to do with friendly bacteria?

Because of this, many of the bacteria in your digestive tract actually use your blood type as a preferred food supply. In fact, blood group specificity is common among intestinal bacteria with almost 1/2 of strains tested showing some blood type A, B, or O specificity. To give you an idea of the magnitude of the blood type influence on intestinal microflora, it has been estimated that someone with blood type B will have up to 50,000X more of some strains of friendly bacteria than either blood type A or O individuals. • Second, some strains of beneficial bacteria actually can have lectin-like hemagglutinin activity directed against your blood type, so avoiding those is a good idea. • Polyflora Blood Type Specific Probiotics also blend ‘prebiotics’ (foods which provi
