Why is it that decrease of bifidobacteria in gut is associated with aging and many diseases?
There are two kinds of bacteria in human gut, one is health promoting and the other is harmful to health. Bifidobacteria is health-promoting bacteria. As one gets older, due to the decrease of gastric-intestinal fluid secretion and other factors involved, bifidobacteria in gut will gradually reduce in number. This is especially true in senior citizens. Reduction in bifidobacteria is well known to be associated with aging, reduction in immunity and diseases such as cancer and arthritis. It is believed that mental stress can result in imbalance of endocrine secretion as well as deteriorating health. In the meanwhile, bifidobacteria in gut reduce dramatically, too. The bad bacteria in gut grow more rapidly and lots of toxins are produced due to good one’s reduction. In turn, it reduces immune function in human body and as a result, diseases come along. The experiments with rats indicate that the increase of harmful bacteria will induce colon cancer and liver cancer. Besides, many other di
