Yogurt is rich in probiotics. Probiotics refer to a kind of intestinal physiological bacteria beneficial to human life and health, such as Bifidobacterium, Lactobacillus acidophilus, Lactobacillus casei and other lactic acid bacteria. At present, there are many kinds of yogurt products on the market, including solidified yogurt, stirred yogurt and juice yogurt with different juices, which are sweet and sour and suitable for different tastes. No matter what kind of yogurt it is, it is characterized by containing lactic acid bacteria. These lactic acid bacteria will secrete substances beneficial to human health when they propagate in human intestine, so yogurt has more benefits to human body: First, it can decompose lactose and protein in milk, making it easier for human body to digest and absorb; Second, yogurt can promote the secretion of gastric juice, increase appetite and strengthen digestion; Third, lactic acid bacteria can reduce the production of some carcinogens, so they have anti-cancer effects; Fourth, it can inhibit the reproduction of spoilage bacteria in the intestine, weaken the toxins produced by spoilage bacteria in the intestine, maintain the normal flora balance in the intestine, and adjust the beneficial flora in the intestine to a normal level.
Lactic acid bacteria are intestinal scavengers, which can settle in the intestine, make beneficial changes in the composition of intestinal flora, promote the secretion of digestive enzymes in the body and intestinal peristalsis, remove intestinal garbage and inhibit the reproduction of spoilage bacteria.
