Modern research has confirmed that milk is rich in minerals, such as phosphorus, calcium, zinc, iron, copper, manganese and molybdenum. Most importantly, milk is the main source of calcium needed by human body, and the proportion of calcium and phosphorus in it is very suitable, which is beneficial to human body's absorption of calcium and is one of the best sources of calcium for human beings.

1 liter of fresh milk contains about 1250 mg of active calcium, which ranks first among all foods, and is almost10/0 times that of rice, 75 times that of lean beef and10/0 times that of lean pork. Middle-aged women before and after menopause often drink milk to slow down bone loss.

Unfavorable crowd

1, people who are often exposed to lead in work and life should not drink milk, because lactose in milk can promote lead to absorb savings in the human body, which is more likely to cause lead poisoning. You can drink yogurt instead, because there is very little lactose in yogurt, and most of it has become lactic acid.

2, lactose intolerance. Some people lack lactase in their bodies, so the lactose in the milk ingested in the human body cannot be converted into galactose and glucose for absorption and utilization by the small intestine, but directly enters the large intestine, which increases the osmotic pressure of the intestinal cavity and causes the large intestine mucosa to inhale a lot of water.

In addition, lactose can be fermented by bacteria in the intestine to produce lactic acid, which can stimulate the large intestine and cause abdominal distension, abdominal pain, exhaust and diarrhea. Lactose intolerant people should decide whether to drink or not according to their own physical conditions, otherwise it will cause abdominal distension and diarrhea.

3. People who are allergic to milk. Some people will have symptoms such as abdominal pain and diarrhea due to allergies after drinking milk, and some people with severe allergies may even have rhinitis, asthma or urticaria.
