What are the main contents of China residents' nutritional dietary guidelines?

With the improvement of people's living standards, promoting health with dietary nutrition has become the goal people pursue. This requires the knowledge of reasonable nutrition and the requirement of balanced diet. Entrusted by the Ministry of Health, China Nutrition Society revised and formulated the Dietary Guide for China Residents. It is some guiding opinions put forward by nutrition workers to sum up the principles of nutrition, aiming at helping people choose and match food reasonably, so as to achieve the purpose of reasonable nutrition, reducing diseases and promoting health. The Dietary Guide for China Residents has eight contents: 1. All kinds of foods are mainly cereals, and each food contains different nutrients. No food can supply all the nutrients needed by the human body, so the daily diet must be properly matched with various foods to meet the human body's needs for various nutrients. Cereal food is the main body of China's traditional diet and the main source of human energy. It can also provide carbohydrates, protein, dietary fiber and B vitamins. We should pay attention to fine lines. 2. Eat more vegetables, fruits and potatoes. Vegetables, fruits and potatoes are rich in vitamins, minerals and dietary fiber, which play an important role in protecting cardiovascular health, enhancing disease resistance and preventing some cancers. 3, often eat milk, beans or their products. Milk contains high calcium, which is an important source of calcium and high-quality protein. China residents are generally short of calcium, which is related to the lack of milk in their diet. Eating milk regularly can improve the bone density of children and adolescents and slow down the bone loss of the elderly. Beans are rich in nutrients, including high-quality protein, unsaturated fatty acids, calcium and B vitamins, which can not only improve the supply of dietary nutrients, but also avoid the adverse effects caused by eating too much meat. 4. Eat proper amount of fish, poultry, eggs and lean meat, and eat less fat and meat-oily fish, poultry, eggs and lean meat are important sources of high-quality protein, fat-soluble vitamins and some minerals. Diet should contain appropriate amounts. The intake of animal food in some cities and most rural areas in China is insufficient, so the intake should be increased appropriately. However, residents in some big cities eat too much meat, which is also harmful to their health. It is necessary to reduce it appropriately, especially pork and meat oil. 5, food intake and physical activity should be balanced, and maintain a suitable weight. Food intake and physical activity are two main factors to control weight. Excessive food intake and insufficient activity will lead to obesity, and vice versa, which is not a healthy performance. Therefore, it is necessary to keep the balance between food intake and energy consumption and keep the weight within a suitable range. 6. Eat light and salty food, not too greasy and salty, and eat less fried and smoked food. The salt intake per person per day should not exceed 6 grams. Eat less sodium-containing foods such as pickles and monosodium glutamate. Eating more salt will increase the risk of hypertension. 7. If you drink alcohol, it should be limited to liquor, which contains no other nutrients except energy. Excessive drinking will reduce appetite, cause multiple nutritional deficiencies, damage the liver, and increase the risk of hypertension and stroke. If you want to drink, you can drink a small amount of low-alcohol wine. 8. When eating clean and hygienic foods that are not easy to deteriorate, you should choose foods that have good appearance and meet the hygiene requirements. Pay attention to the sanitary conditions when eating, including the environment, tableware and the sanitary conditions of the producers. The above guidelines are applicable to healthy adults and children over 2 years old. On this basis, there are "dietary guidelines for different groups of people" for specific groups such as infants, preschool children, school-age children, teenagers, pregnant women, nursing mothers and the elderly.
