How to make the body of bifidobacteria in the elderly to be activated and mass propagation? The first thought of scientists is to take live bacteria to increase flora, but studies have shown that live bacteria can not attach to the human intestinal wall formation of flora, can only survive for a short time; Once the stop taking live bacteria, the advantages of colonic viability is not There is. To this end scientists have developed a special food supply bifidobacteria - bifidus factor. It is a kind of food that is not digested and absorbed by the human body. The human body can directly enter the intestine after taking it, and can selectively stimulate the growth and vitality of Bifidobacteria so as to make large-scale proliferation of Bifidobacteria in itself to resist the intrusion of harmful bacteria , Reduce the incidence of disease. Therefore, "Bifidus factor" is a factor of proliferation of Bifidobacterium, which is praised by many scientists as "the fifth generation of health products".
