1, pure milk: the so-called pure milk, look at the ingredients list, there is only one kind of "raw milk". Pure milk is divided into pasteurized milk and normal temperature milk. Pasteurized milk is what we usually call "fresh milk", and its formula is the same, but its sterilization process is different.

2. Normal temperature milk: it is the milk that is instantly disinfected at the ultra-high temperature of135 ~150℃. All harmful bacteria are killed at high temperature, but beneficial bacteria are also killed. Its shelf life is mostly more than 90 days, and it can be stored at room temperature.

3. Skim milk and low-fat milk: The fat in milk is reduced or completely removed through technology, but its nutritional value is completely unchanged. The fat content of whole milk is about 3%, low-fat milk (semi-skimmed milk) contains fat 1.0- 1.5%, and whole skimmed milk contains fat 0.5%. For obese people and the elderly, it is better to choose low fat and skim.

4. Pure Yogurt: It is yogurt fermented with milk. The nutritional value of this yogurt is the same as that of pure milk, but the lactose in milk is turned into lactic acid by fermentation process, which is a gospel for lactose intolerant people. However, pure yogurt is rare in the market, and it is more flavor yogurt, which does not belong to the category of healthy dairy products.

5, Shuhua milk: It sounds quite tall. In fact, lactase is added to hydrolyze the lactose in milk, which is suitable for friends who usually have a stomachache when drinking milk. Except lactose, protein, fat and calcium in Shuhua milk have no difference in nutrient absorption. If you usually drink milk without any adverse reactions, then you can make a reasonable choice.
