The Intestinal Microflora

There's a complex ecosystem of bacteria in our intestines and while that system is relatively constant, it's also subject to change. The types and numbers of bacteria are related to factors ranging from personal stress levels (Virkha et al., 1999; Holdeman et al., 1976), antibiotic intake (Bourlioux et al., 2003), aging (Minelli et al., 1993) and, of course, diet (Fernandez F et al., 1985; Roberfroid, 1996; Bourlioux et al., 2003). Recent research suggests that when our intestinal microflora or gut flora is unbalanced, overall well-being can be negatively affected.

Over 400 types of bacteria live in our gastrointestinal tracts. Contrary to popular belief, most of these bacteria are not pathogenic or harmful. A great amount of them are necessary for normal growth and development, while the function of other bacteria remains unknown. This complex microbial ecosystem plays a vital role in the proper development of our immune system and aids in the digestion and absorption of nutrients. Interactions between us and these microorganisms in our bodies (and among the microorganisms themselves) are crucial to our health and well-being.
