Its basic requirements are as follows:

First, provide all-round, sufficient and appropriate proportions of nutrients. China Nutrition Society divides human food into five categories: the first category is cereals and potatoes, cereals include rice, flour and miscellaneous grains, and potatoes include potatoes, cassava and sweet potatoes. The second category is animal food, including meat, poultry, fish, milk, eggs and so on. The third category is beans and nuts, including soybeans, other dried beans and nuts such as peanuts, walnuts and almonds. The fourth category is vegetables, fruits and fungi. The fifth category is pure energy substances, including animal and vegetable oils, starch, edible sugar and wine. It is suggested that the daily diet should include the above five kinds of food, with 2 ~ 4 kinds of food in each kind, and at least 10 ~ 20 kinds should be eaten every day, with more than 30 kinds being the best.

Second, ensure food safety. Food must not contain all kinds of harmful factors harmful to human body, and food should be kept fresh and hygienic to ensure the safety of residents. Once food is polluted or deteriorated by harmful substances, the nutrients in food will be destroyed, which will not only fail to meet the nutritional needs of the body, but also cause acute and chronic poisoning and even cancer.

Third, scientific cooking and processing. The scientific processing and cooking of food aims at eliminating anti-nutritional factors and harmful microorganisms in food, improving the digestibility of food, changing the sensory characteristics of food and promoting appetite.

According to the physiological conditions, labor intensity and working environment of different groups of people, the dining system should be arranged reasonably. Reasonable dining system is helpful to promote appetite and normal secretion of digestive juice, so that food can be fully digested, absorbed and utilized. Adults should adopt the system of three meals a day and develop good eating habits such as not picky eaters, partial eclipse and overeating.
