Balance the supply and consumption of various nutrients, which not only meets the needs of human growth and maintenance of physiological functions, but also promotes health. The basic requirements of a reasonable diet include balanced diet, control of total calories and diversification of diet.
1, balanced diet: The first principle of a reasonable diet is to ensure a balanced intake of various nutrients. Nutrients needed by human body include protein, fat, carbohydrates, vitamins and minerals, etc. These nutrients have their own specific functions and needs in human body. A reasonable diet should include all kinds of foods to provide enough energy and various nutrients, while avoiding excessive intake of some nutrients.
2. Control the total dietary calories: The second basic requirement for a reasonable diet is to control the total dietary calories. The calories needed by the human body should be balanced with the calories consumed by the body to maintain a healthy weight. If you eat too many calories, it will lead to obesity and other health problems. A reasonable diet requires proper control of food intake, and at the same time, attention should be paid to choosing foods with low calorie and high nutrition.
3. Diet diversification: The third basic requirement for a reasonable diet is diet diversification. The nutrients needed by the human body come from different foods, so a reasonable diet should include a variety of foods. Different foods can provide different nutrients and make the diet more colorful.
Benefits of a reasonable diet:
1, Maintain good health: A reasonable diet can provide nutrients needed by the body, such as egg confession, carbohydrates, fats, vitamins and minerals. These nutrients are essential to the normal operation of the body. For example, protein contributes to the repair and growth of the body, carbohydrates provide energy, and vitamins and minerals participate in various biochemical reactions of the body. By reasonably matching these nutrients, we can ensure that the body gets enough nutrition, thus maintaining good health.
2, enhance immunity: a reasonable diet can also enhance the body's immunity. Antioxidants and other nutrients in food can help the body resist diseases and infections. These antioxidants and nutrients can promote the growth and function of immune cells and improve the body's resistance to diseases. Through a reasonable diet, you can enhance your immunity and reduce your chances of getting sick.
3. Prevention of chronic diseases: A reasonable diet can also prevent the occurrence of chronic diseases. Foods high in fat, sugar and salt will increase the risk of chronic diseases such as heart disease, diabetes and hypertension. On the contrary, foods rich in vegetables, fruits, whole grains and healthy fats can help reduce the incidence of these chronic diseases. By avoiding unhealthy food and reasonably matching healthy food, we can prevent the occurrence of chronic diseases and improve the quality of life.
