Only a balanced diet can meet the heat energy and all nutrients required by normal physiology of adults, and can be digested, absorbed and utilized reasonably to achieve the purpose of reasonable nutrition and health promotion. According to China Residents' Dietary Pagoda, it is an intuitive and quantitative expression of balanced diet.
The overall balance is to eat everything, not picky eaters, not partial eclipse. As we all know, no single natural food can provide all the nutrients needed by the human body. Therefore, a reasonable diet must consist of a variety of foods in order to achieve a balanced diet. Foods can be divided into five categories according to their ingredients.
The first category is cereals and potatoes, which mainly provide carbohydrates, protein and B vitamins, and are the main sources of dietary energy in China.
The second category is animal foods, such as meat, poultry, eggs, fish and milk, which mainly provide protein, fat, minerals, vitamins A and B and essential fatty acids.
The third category is soybean and its products, which mainly provide protein, fat, cellulose, minerals and B vitamins.
The fourth category is vegetables and fruits, which mainly provide cellulose, minerals, vitamin C and carotene.
The fifth category is pure heat energy food, including animal and vegetable fats, various edible sugars and alcohol, which mainly provide heat energy and essential fatty acids.
