Because although milk contains protein needed by human body, it also contains a lot of fat. Drinking too much will affect the weight loss effect. But skim milk can, because you eat less during weight loss, so your body needs not only vitamins, but also some energy. Skim milk is a good choice, which can not only supplement the nutrients needed by the human body, but also will not affect the effect of losing weight.
Skim milk removes part of the fat in normal milk, so that the fat content is below 0.5%, which is less than 1/7 of ordinary milk. Skim milk here refers to whole milk, which is relative to whole milk, and there is low-fat milk in the middle. The production of this kind of milk meets the nutritional needs of modern people to pursue "high protein and low fat".
At the same time, the original "fragrant and strong" taste of milk has disappeared. In fact, people have a deep misunderstanding about "whole milk". Compared with animal offal, cream products and other foods, the fat content of whole milk is not surprising, it only contains 3.7% ~ 5%, unless it is a special group with diabetes and hyperlipidemia, it does not need special attention.
