In terms of fat content:
The fat contents of whole milk, low-fat milk and skim milk are 3%, 0.5% ~ 2% and less than 0.5% respectively.
Because of the high fat content, whole milk also has more bile solids content. However, low-fat/skim milk has less fat, lower bile solids and lower calorific value than whole milk.
For the contemporary people who pursue perfect high-protein food and low fat, low-fat and skim milk are more popular. But for the development of children, this is not the case.
According to related research, the human fat of milk contains oleic acid with health care and cancer prevention functions, and also contains conjugated linoleic acid (CLA).
* * * Conjugated linoleic acid can clear the visceral fat index in the body. Compared with human fat, visceral fat index is more harmful to health!
From the level of fat-soluble vitamins:
Whole milk contains a lot of fat-soluble vitamins, such as vitamins D, D, E, K, etc. Due to the separation of human fat, low-fat/skim milk has little or no fat-soluble vitamins.
As we all know, vitamins are very beneficial to health and the digestion of minerals in milk.
A large number of scientific studies have confirmed that vitamin deficiency is closely related to obesity, especially vitamin D deficiency. Vitamin d can reduce the formation of fat.
From the taste level:
The strong taste of milk comes from the body fat in milk. Low-fat/skim milk reduces the fat content, but it also lacks the flavor of milk. Some low-fat skim milk will continue to use some additives in order to better improve the taste.
Generally speaking, from the perspective of children's nutrition and health, it is more strongly recommended to give children full-fat milk.
According to a study in the outpatient department of a hospital in Toronto, Canada, children who drink whole milk are 40% less likely to be overweight or obese than those who drink low-fat milk. In other words, drinking whole milk can make children slimmer.
Children over 2 years old are overweight or have a large family history of obesity, hypertension or heart disease. Generally speaking, children are advised to drink slimming milk with a fat content of about 2% (2%), and children under 2 years old should not drink low-fat/skimmed milk with a fat content of only 1%, because low-fat/skimmed milk does not have the necessary oleic acid.
