Winter diets are subject to changes in physiological function and appetite. Therefore, it is very necessary to properly adjust the diet and ensure the nutrition that the human body needs, in order to improve the cold resistance and immunity of the organism.

There are many diets in winter, but the general principle is that it should be used to keep warm and keep dry. Should add more heat food. In winter, body resistance to cold requires a lot of calories. In order to adapt to this feature, dietary supplements should include more calorie-rich nutrients, such as carbohydrates, fats, proteins, etc., to improve the body's ability to withstand low temperatures. In particular, foods rich in protein should be added, and lean meat, chicken, duck, eggs, fish, milk, and soy products should have high protein content.
