Therefore, the protein in milk is high-quality protein, and its content is higher than that of human milk.

　　The fat in milk is about 3.4∽3.8%, of which oleic acid accounts for 33%. Therefore, the fat in milk has a low melting point, small particles, and is in a highly dispersed colloidal state, which is easy to digest and absorb.

　　Yogurt is fermented with lactic acid bacteria. Lactic acid lowers the pH of the intestine, inhibits the growth of E. coli, and has antidiarrheal and antiviral effects. Yogurt can provide the body with immunity, stimulate the body to produce γ-interferon, increase the activity of natural killer cells, promote the production of antibodies, and inhibit or kill tumor cells. Whole milk also has a similar effect. American scientists recently proposed that drinking more whole milk can help prevent cancer , especially in milk fat

　　Contains a small amount of special fatty acids (CLA fatty acids), which can prevent blood cancer, breast cancer, colorectal cancer, ovarian cancer and prostate cancer.
