It
is important to eat a well-balanced, whole food diet in order to maintain healthy
colonies of microbial flora. This is due to the varied nutritional requirements
of each genus of microbe. If we think in terms of our own nutritional
requirements and the consequences of not eating right, we can begin to
understand microbial requirements.
For
instance, if I ate a diet that was devoid of vitamin C, I would become more susceptible
to colds, my gums would begin to bleed, I would bruise more easily, and I would eventually develop scurvy. Why?
Because vitamin C is an antioxidant, and it is a source of collagen. So I would
become unhealthy with a lack of vitamin C. My microbes become unhealthy without
prebiotics. Consider prebiotics as microbe food.
Prebiotics
of various types are found as natural components in milk, honey, fruits, and
vegetables, such as onion, garlic, artichoke, banana, and barley. Asparagus, beets, chicory, tomato, and rye are sources of
fructooligosaccharides (FOS).
FOS
do not breakdown during digestion. They are instead metabolized or eaten by
beneficial microbes and they create short chain fatty acids. Having FOS in your
diet has also been shown to increase mineral absorption, and to decrease serum
cholesterol and triacylglycerol.
Some
microbes, like Lactobacillus acidophilus have been studied extensively. This
probiotic, which is commonly found in yogurt, has been found to help regulate
both diarrhea and constipation, IBS, allergies, eczema, allergies, and it
appears to improve immune function. But it needs prebiotics to do these
wonderful things. It eats FOS and Isomaltulose.
Isomaltulose
is a new candidate as a prebiotic. It naturally occurs in honey, sugarcane
juice, and its products such as food-grade molasses. It
is not found in refined sugar.
Galactooligosaccharides (GOS) and raffinose oligosaccharides are also prebiotics. GOS are
found naturally in human and bovine milk. Seeds of legumes, lentils, peas,
beans, chickpeas, and mustard are rich in raffinose oligosaccharides.
