Milk can be heated, but not boiled. The reason is that some vitamins will be destroyed after boiling, and the calcium in milk will also be converted into calcium phosphate to precipitate, which will affect the body's absorption.
Milk is rich in calcium, so there is no need to supplement calcium. "Calcium-added milk" and "high calcium milk" are unnecessary. Excessive calcium will combine with casein in milk to form clots, which will reduce the nutritional components.
Don't just drink milk for breakfast. Because drinking milk on an empty stomach will accelerate gastrointestinal peristalsis and cause malabsorption. The principle of balanced diet requires that it is best to eat a variety of foods at the same time. If you can eat bread, cake and other foods before drinking milk for breakfast, it will be beneficial to the nutritional balance.
Don't eat chocolate when drinking milk. The reason is that oxalic acid in chocolate will combine with calcium in milk to form calcium oxalate, which makes calcium not fully utilized.
It is not advisable to take medicine with milk instead of water, because milk can react with many drugs, reduce the efficacy and even produce new toxic substances.

Milk is milk and has high nutritional value. Studies show that every100g of milk contains 3.5g of protein, 4.0g of fat, 5g of carbohydrate, 93mg of calcium120mg of phosphorus, 0.2mg of iron, 0.04mg of thiamine, 0.13mg of riboflavin, 0.2mg of nicotinic acid, and 0.2mg of vitamin A42. The content of lysine in milk protein is second only to that of eggs. All carbohydrates are low-sweetness lactose, which can promote gastric juice secretion and gastrointestinal peristalsis, and can be converted into lactic acid in the intestine to inhibit the growth of spoilage bacteria.

Milk is nutritious and delicious, but it is not suitable for everyone. The following personnel should pay special attention to:
Regular exposure to lead
Lactose in milk will promote the absorption and accumulation of lead in human body, which will easily lead to lead poisoning. Therefore, people who are often exposed to lead should not drink ordinary milk. It is suggested to drink yogurt instead, because there is very little lactose in yogurt and most of it becomes lactic acid.
Patients with milk allergy
People who are allergic to drinking milk may have symptoms such as abdominal pain and diarrhea after drinking milk, and those who are seriously allergic may also induce diseases such as rhinitis, asthma or urticaria.
Patients with reflux esophagitis
Milk can reduce the pressure of lower esophageal sphincter, thus increasing the reflux of gastric juice or intestinal juice, so patients with reflux esophagitis should not drink it, otherwise it may aggravate the condition.
Abdominal cavity and gastrectomy
People who have undergone abdominal or gastric resection have been affected by the decrease of lactic acid enzyme in their bodies. Once they drink milk, lactose will not decompose and ferment in the body, and then produce water, lactic acid and a lot of carbon dioxide, which will lead to bloating.
Abdominal pain and diarrhea patients
People who usually have abdominal pain, diarrhea, bloating and other symptoms will get worse after drinking milk.
Patients with irritable bowel syndrome
Irritable bowel syndrome (IBS) is a common intestinal functional disease, which is characterized by the motor function of intestinal muscles and the secretion of mucus by intestinal mucosa, resulting in abnormal irritating physiological reactions, and it is easy to cause allergies after drinking milk.
