Milk is one of the oldest natural dairy products. Milk can reduce the pressure of esophageal sphincter, thus increasing the reflux of gastric or intestinal juice.

Milk and its products are one of the important sources of protein, calcium, phosphorus, vitamin A, vitamin D and vitamin B2 in the diet. It contains complete nutrients, with high nutritional value and easy digestion and absorption. It is most suitable for patients, young children, and the elderly.

Milk is rich in nutrition, but do not drink raw milk. There are a large number of bacteria and even viruses in raw milk. All major dairy products factories carry out anti-virus and sterilization through instantaneous ultra-high temperature, and the quality can be guaranteed.

Some people like to drink milk on an empty stomach in the morning. In fact, this is unscientific. When eating on an empty stomach, the stomach peristalsis faster, and the nutrients in the milk are discharged into the large intestine before digestion and absorption, resulting in the loss and waste of many nutrients. Therefore, it is best to drink milk after eating steamed bread, biscuits, bread, and other foods before drinking milk, so that the nutrients in the milk can play a full role, which is conducive to digestion and absorption.

When drinking milk, it is recommended to drink slowly, which will make the protein in the milk fully contact with the stomach acid in the body and form a small clot, which is conducive to digestion and absorption. At the same time, it is not recommended to drink frozen milk, because after the milk is frozen, the separated taste of fat and protein in the milk will obviously weaken, and the nutrients will not be easily absorbed. It is recommended to heat it to below 75 ℃. It is also unscientific to drink the boxed liquid milk after boiling.
