Some 100 trillion bacteria populate the human gut, a number that is 10 times greater than the number of cells in the human body. Because of the sheer size and importance of the gut bacteria, this microbial population can be viewed as a bacterial organ, about the size of your liver and just as important. There are some 400 species of bacteria in the gut including Bacteroides, Lactobacillus, Clostridium, Fusobacterium, Bifidobacterium, Eubacterium, and Peptostreptococcus. Gut bacteria with identified as suitable ingredients in food supplements include Bifidobacterium and Lactobacillus species. It is critical to the maintenance of human health that a balance is preserved between these species.
