This type of food mainly provides the body with carbohydrates, protein, minerals, fiber and B vitamins, and is the main source of energy supply for the body. The daily demand of the human body is related to individual energy needs, living habits, labor intensity and other factors, and is also affected by the supply of non-staple food. Under normal circumstances, adults engaged in moderate labor intensity need about 500 grams of grains every day.

(2) Meat and dairy products: including pigs, cattle, sheep, chickens, ducks, geese and other poultry and eggs, as well as fresh milk and various dairy products. It mainly provides protein, fat, inorganic salts, vitamin A and B vitamins to the body. The protein provided by this type of food is mostly high-quality protein.

(3) Soybeans and their products: including various soy products. This type of food mainly provides protein, fat, fiber, inorganic salts and B vitamins.

Vegetables and fruits are essential in a balanced diet, otherwise the body's needs for certain vitamins and minerals will not be met, and the supply of fiber will also be insufficient. It is best for adults to eat 400-500 grams of fruits and vegetables every day.

(5) Pure thermal energy foods: including various animal and vegetable oils and edible alcohol products. This type of food mainly provides energy for the body. Vegetable oil can not only increase the flavor of the food, but also provide the vitamin E and essential fatty acids needed by the body, and promote the absorption of fat-soluble vitamins.

Nutritional research has found that at least 42 kinds of nutrients are needed to maintain human life and health, including various proteins, fats, sugars, cellulose, vitamins, inorganic salts and water. These nutrients must be composed of a variety of different foods in order to achieve the balance of the body's demand for nutrients. Therefore, when we eat every day, including the above five types of foods is the best way to develop a healthy and nutritious body. Basic requirements necessary for eating habits. According to China's current national conditions, we believe that the Chinese people's dietary structure should still maintain the traditional diet of cereals, supplemented by vegetables and fruits, and appropriately increase the intake of beans, animal foods, especially dairy products. . Since various types of food contain different amounts of energy, in addition to maintaining a balanced diet, you must also pay attention to the portions of each type of food taken in order to obtain enough energy to supply the body's needs.
