It is beneficial to change the composition of intestinal flora, improve the gastrointestinal function of human body, restore the balance of intestinal flora, form an antibacterial biological barrier and maintain human health. Lactic acid bacteria metabolize in the intestine to produce lactic acid, which can inhibit the growth and reproduction of harmful bacteria, stimulate intestinal movement, increase the water content of feces, moisten the intestines and relax the bowels, and also have obvious therapeutic effects on ulcers, diarrhea and constipation. Inhibit the reproduction of spoilage bacteria, remove toxins produced by spoilage bacteria, and remove intestinal garbage. It can inhibit spoilage bacteria such as Listeria, Staphylococcus, and famous wine bacteria, and inhibit and eliminate gram-negative bacteria, catalase-positive bacteria, Escherichia coli, Salmonella, etc. Inhibit cholesterol absorption and lower blood pressure with low fat. Lactic acid bacteria can reduce the absorption of cholesterol in the intestine, convert some cholesterol into cholate and excrete it.

Immune regulation, improve human immunity and resistance. Active lactic acid bacteria inhibit spoilage bacteria and pathogens harmful to human body by proliferation in human body, and their metabolism produces lactic acid and effective metabolites (antibacterial substances, vitamins, etc. ), and lactic acid bacteria themselves can also improve immunity. Anti-tumor and cancer prevention effects. Lactic acid bacteria can absorb 98% of carcinogenic nitrosamines in the intestine and reduce the occurrence of intestinal cancer. Lactic acid bacteria can also stimulate intestinal mucosal lymph nodes, increase the activity of immune cells and macrophages, and set obstacles for the invasion and reproduction of pathogenic bacteria. Improve SOD activity, eliminate human free radicals, and have anti-aging and longevity effects. Effectively prevent female genitourinary system bacterial infection. Control the level of human endotoxin, protect the liver and improve the detoxification and detoxification function of the liver.

Lactic acid bacteria beverage, with water as the main component, followed by sugar, less milk content, beverage, plus food additives. In addition, only "active lactic acid bacteria drinks" contain live lactic acid bacteria, but other types of lactic acid bacteria drinks do not.

The main raw materials of yogurt are milk (or milk powder), lactic acid bacteria starter and sugar. Generally, there is no water and few food additives. The content of protein is over 2.5%, which is equivalent to 2.8% of pure milk and much higher than 0.7% of lactic acid bacteria beverage. Yogurt also contains a large number of live lactic acid bacteria, which is beneficial to intestinal health after long-term drinking. Lactic acid bacteria drinks only contain active lactic acid bacteria when stored at low temperature. In addition, the contents of calcium and vitamins in yogurt are much higher than those in lactic acid bacteria drinks and milk, among which lactic acid can also promote the absorption of calcium and is one of the good sources of calcium supplementation. Therefore, yogurt is suitable for drinking every day. Lactic acid bacteria are not suitable for drinking every day because of their high energy and low nutrient density.
