It can enhance the immune function of the body, not only does not cause cancer, but also has antibacterial and anticancer effects.

Rumor has it that milk causes cancer, mainly because it contains tyrosine and insulin-like growth factor. First there is no direct and strong evidence that tyrosine directly causes cancer. Secondly, regarding insulin-like growth factor, it belongs to a kind of protein which is actually a normal human regulatory factor. Generally speaking, it is not a problem when consumed in moderation, and daily consumption of milk will not lead to too much insulin-like growth factor in the body. After high-temperature treatment, it will lose its activity, and after being consumed, it will enter the intestinal tract, where most of it will be broken down by digestive enzymes and will not affect the human body. Research has also shown that consuming milk containing insulin-like growth factor does not lead to changes in the concentration of the factor in the human blood, nor does it directly cause cancer.

It is good to drink milk in general, whether it is yogurt or plain milk for the body. Because milk contains biochemical substances that can make a person tired and sleepy levotryptophan and trace substances, these substances have a certain sedative-hypnotic effect, especially levotryptophan, which is the brain synthesis of hydroxyl color of the main raw materials.

The temperature of the water used should not be too high. You can't use boiling water to make powdered milk or cook it directly. A more appropriate temperature is 50-60 degrees, too high a temperature will destroy the protein structure of milk and reduce the nutritional value. In addition, you should not use copper containers when heating or preparing milk, because copper containers will react with milk. It is recommended to use glass cups.
