With the continuous improvement of living standards, milk has become very common in daily life. Every household can drink milk. Milk is also of great benefit to human health.
But some people think that there are preservatives in milk, which are harmful to the human body. So is there a basis for this statement? Which milk is really harmful to the body? Let’s learn about it together now.
Milk is full of preservatives, which is not only toxic but also carcinogen?
Some people believe that milk is full of preservatives, and this understanding is incorrect. Milk has its special sterilization methods, namely pasteurization and ultra-high temperature sterilization.
pasteurization method refers to the use of low temperature (60~85℃) to sterilize milk. The shelf life of sterilized milk in this way is generally 2~7 days; the ultra-high temperature sterilization method is to instantly heat the milk to 135~150℃ for a few seconds, which has a strong sterilization effect. This type of milk generally has a shelf life of more than 6 months.
Under normal temperature conditions, microorganisms in the milk reproduce slowly, and when the temperature exceeds 30℃, a large number of bacteria will be produced, which destroys the nutritional structure of fresh milk and makes it spoiled and deteriorated.

3. Peanut Milk
Some people think that peanut milk is more nutritious, but it is actually wrong. peanut milk is mainly water and white sugar, and the milk content is very low.
Peanut milk cannot be considered as milk, it can only be called a dairy product "beverage". Drinking it frequently will not obtain nutrition and may also affect your health.

Precautions for drinking milk
. It is not recommended to freeze milk
The thawed milk will appear solidified precipitates, the cellulite tastes lighter, abnormal smell appears, the juice is watery, and the nutritional value is reduced.
. Do not drink milk on an empty stomach
When you are on an empty stomach, the human body is in a hungry state, so the demand for energy is also relatively large. At this time, the milk taken will be directly converted into calorie consumption, which leads to the time of milk in the stomach and intestines and is quickly excreted from the body through the intestines, which is not conducive to the body's absorption of nutrients.
. It is best to drink milk in the morning and at night
Milk is best to drink in the morning, because milk is rich in calcium, phosphorus and other substances. If you drink milk in the morning, it can absorb calcium well into the body.
