What are friendly bacteria and what is the benefit of increasing their population?
Bifidobacteria and Lactobacilli are considered friendly intestinal bacteria because they help to digest food and boost the body’s resistance to infection and disease. The primary role of friendly bacteria is to defend the lower intestinal tract from bad bacteria such as E. coli and Clostridia. More good bacteria makes the intestinal environment slightly acidic which is not desirable for the potentially harmful bacteria.
