Most of the sugar contained in milk is lactose, but some people lack of lactase in their digestive juice, so it will greatly affect the digestion, absorption and utilization of lactose by the body. If these people drink milk, it may cause stomach discomfort or even diarrhea, known as "lactose intolerance". In such a case, they should choose yogurt instead of milk.

This is because yogurt contains lactic acid bacteria, so the lactose in milk can be fermented and transformed into lactic acid. As a result, people with "lactose intolerance" will not suffer from diarrhea after drinking yogurt, which just solve the dangers that may arise when they drink milk. Then, what kind people should drink yogurt instead of milk?

First, people who are taking antibiotics
Antibiotics play an important role in the control of pathogenic bacteria, but at the same time, it also suppresses the non-pathogenic bacteria, which may lead to a variety of symptoms such as loss of appetite, nausea, vomiting, dizziness, and so on. While yogurt contains a kind of active mycobacterium, which can regulate the imbalance of gastrointestinal flora.

Second, atherosclerosis and hypertension patients
Some nutrition experts have found that yogurt contains a kind of "milk factor", which has the effect of reducing the serum cholesterol in human body. According to the experiment, if one drinks 720 grams of yogurt every day, after a week, the serum cholesterol in his body can be decreased significantly.

Third, cancer patients
During the fermentation process of lactobacillus contained in yogurt, it will produce acetic acid, lactic acid and formic acid, which can block the formation of carcinogenic nitrosamines, so as to play a role in cancer prevention. In some European countries, people believe that "drinking a cup of yogurt every day can make women away from breast cancer".

Fourth, old and weak people
The lactic acid bacteria in yogurt can break down the lactose in milk and form lactic acid, so as to inhibit the growth and reproduction of spoilage. Yogurt not only contains a large number of protein and vitamin A itself, but can also synthesize various kinds of essential nutrients needed by human body, such as vitamins B, folic acid and vitamin E. As a result, it is very beneficial to those old and weak people.

Fifth, osteoporosis patients
Yogurt contains plenty of calcium lactate, which can be easily absorbed by the body. This provides the patients with enough calcium, which plays an important role in the prevention and treatment of osteoporosis.
