Q: What are probiotics? Should I be taking them?
A: Probiotics are a living bacterial supplement
that supports health by improving microbial balance in
the intestines. Our intestines support as many as 400
different types of bacteria. Some of these bacteria are
helpful while some are harmful. In healthy individuals
the intestinal microflora are comprised mostly of helpful
bacteria. Probiotic supplements and foods add beneficial
bacteria to the intestinal mix and therefore help maintain
a healthy balance.
Most people will benefit from taking a probiotic supplement.
It’s a good measure of prevention against disorders
of the intestines that are related to bad bacteria likes
E.coli and Salmonella. Beneficial bacteria counter pathogens
in three ways. First, the intestines have a limited amount
of food and space for bacterial growth. Supplemental probiotics
increase the competition. Second, probiotic bacteria produce
short chain fatty acids that lower the colon pH to a range
in which pathogens can’t thrive. Third, they produce
anti-microbial compounds that kill pathogens. Thus probiotics
reduce the risk of food borne infections.
In the long run probiotics can lower cancer risks because
pathogenic bacteria produce carcinogenic metabolites.
When a healthy bacterial balance is present, pathogens
are reduced and the long-term exposure to carcinogens
is minimized. Probiotic bacteria also create b-vitamins
while helping our bodies digest food and absorb minerals
and ins.
As for whether or not you should take them I would say
the benefits of having a healthy balance of beneficial
bacteria are well worth it. Consuming live cultured foods,
like yogurt and miso, or taking a regular supplement will
do wonders for your colon health. |
