1. Drinking too much milk will lead to excessive intake of protein, which is harmful to health;

Professor Fan Zhihong from the College of Food Science of China Agricultural University pointed out: This statement is based on a survey of westerners. First of all, the diet structure of westerners is characterized by high protein and fat, and contains a lot of milk, cheese, ice cream and so on. However, China people's intake of protein is generally insufficient. Professor Fan told reporters that the content of protein in milk is 3%, which is far lower than that of meat and other foods, and even lower than that of bean products (water tofu 5%, dried tofu 20%). Judging from the dietary structure, the proportion of protein that milk can provide to human body is very small, and it can only play a supplementary role. So "protein's excessive sticking can't hit the nipple".

2. Milk is acidic and will dissolve calcium, which may eventually lead to osteoporosis:

There are tens of millions of middle-aged and elderly osteoporosis patients in China. Professor Fan said that most of them used to drink little or no milk. In fact, milk is rich in metal elements such as calcium, magnesium and potassium, and it is generally weakly alkaline-according to estimates by authoritative departments,100g milk contains about potassium120mg-130mg and calcium1140mg. Because the investigation shows that milk is weakly alkaline, it will not decompose calcium in bones, leading to osteoporosis. In fact, most osteoporosis patients in China live in rural areas where milk consumption is low.

3. Drinking more milk will increase the probability of diabetes or skin allergies;

Regarding diabetes, skin allergies and other issues, Professor Fan pointed out that the survey pointed out that if babies received milk protein six months ago, the chances of developing diabetes in adulthood would increase; Feeding milk to children aged 4-6 months may increase the incidence of skin allergies. Therefore, she said, we should advocate drinking breast milk when children are nursing, and drink less milk. But for children after 6 months, especially adults, drinking milk has nothing to do with the incidence of diabetes and allergies.

4. Drinking more milk will increase the incidence of cancers such as breast cancer;

"Carcinogenicity of milk" has attracted the attention of many researchers in recent years. This is a research report based on the Ottawa meeting of the World Breast Cancer Association. The report says that after injecting growth hormone into cows, a growth hormone called IGF-I will appear in their milk, which will cause cancers such as breast cancer. Professor Fan said: "This kind of nonstandard milk contains growth hormone, which will eventually lead to cancer, which is equivalent to eating pork with lean meat." To solve this problem, it is necessary to require milk producers to strictly control feeding conditions, and it cannot be said that milk is carcinogenic. In fact, milk contains a lot of substances similar to linoleic acid, which have inhibitory effects on many cancers, especially colon cancer.

5. Drinking more milk can cause vascular diseases:

Drinking too much milk at a time can easily lead to arteriosclerosis and induce vascular diseases. A French research institute did a scientific research for 10 years. Casein in milk can produce a molecule which is very dangerous to blood vessels-homocysteine. Homocystine molecules destroy the elastic tissue of blood vessels, making lipids, especially cholesterol, very easy to precipitate on the wall of blood vessels, leading to the gradual blockage of blood vessels and eventually accelerating vascular sclerosis.

6, drinking more milk is prone to cataracts:

Old people who drink too much milk are prone to cataracts. Because fresh milk contains more lactose. Lactose is hydrolyzed into galactose under the action of enzymes. Too much lactose absorbed in the blood will accumulate in the lens of the eye, which will affect the normal metabolism of the lens and denature the crystallin, thus losing its light transmittance and forming senile cataract.

What are the benefits of drinking milk?

1, promoting fetal development

It can be said that milk is a nearly perfect food, and all kinds of nutrients needed by human body can be obtained from milk, so milk is the food closest to the natural needs of human body. Especially for pregnant women, they need a lot of nutrition during pregnancy, which can be obtained from milk. Drinking a glass of milk every day can also promote the development of the fetus.

2, rich in calcium and phosphorus

Milk is rich in nutrition, among which trace elements such as calcium and phosphorus are the most abundant, and the proportion is appropriate, which is very beneficial to human digestion and absorption. Drinking milk regularly can not only promote the healthy growth of teenagers, but also be a good health care product for the elderly to prolong life. The nutritional characteristics of milk can meet the needs of the elderly, so the elderly may wish to drink more milk when they are in health care.

Step 3 lower cholesterol

People with high cholesterol can also drink more milk in their daily life, because milk contains some ingredients that can effectively inhibit the liver from producing cholesterol, which is very healthy for patients with high cholesterol. In addition, some patients with cardiovascular diseases should drink more milk at ordinary times, and milk is called the "natural enemy" of hypertension. Drinking milk regularly can lower blood pressure, thus reducing the incidence of stroke. Moreover, through research, it is found that drinking milk regularly by the elderly can effectively reduce the chance of heart attack and prevent stroke.

Step 4 protect the digestive system

From the benefits of drinking milk, it can also protect the digestive system and effectively promote the healing of ulcer lesions. Experts pointed out that some substances contained in milk can neutralize gastric acid and strengthen the function of the stomach, especially in the recovery and treatment of gastritis. Therefore, patients with atrophic gastritis and duodenal ulcer should drink more milk in their daily life.

Extended data

Milk is a well-known nutritious beverage with good health care and medical value. Milk is a completely protein food, which plays an important role in the formation and development of brain marrow and nerves. The cholesterol content of milk fat is lower than that of meat and eggs, which has the function of lowering cholesterol in the body.

Milk can neutralize gastric acid and prevent gastric acid from stimulating ulcer surface, so taking milk has a good therapeutic effect on digestive tract ulcers, especially gastric and duodenal ulcers. Frozen milk can constrict blood vessels and stop bleeding from peptic ulcer. "Yogurt" made of milk can protect human body from and reduce the invasion of toxic substances, stimulate the secretion of gastric juice and enhance gastrointestinal digestion. It is most suitable for patients with liver diseases, gastrointestinal diseases, the weak and infants.

It is also reported that the choline content in yogurt is particularly high, which can regulate the concentration of cholesterol in the body. At the same time, because yogurt contains orotic acid, it can inhibit the liver from producing cholesterol and reduce the adhesion of cholesterol on the blood vessel wall, thus reducing the total cholesterol content in the blood. Therefore, people suffering from cardiovascular diseases, taking yogurt is very beneficial.
