Friendly Bacteria Fight Colds and Flu

Infants are less likely to suffer from respiratory infections when they are given probiotics, or friendly bacteria, according to a study funded by the British Hournal of Nutrition.  In another study, in Italy, researchers found that adults' resistance to flu bugs improves with probiotics.

Both studies used a specific strain of friendly bacteria, B. Lactis, BB - 12, and the adult study also used L. Casei 431.  Each of these strains is found as an ingredient in various probiotics products.
