How to eat a healthy and nutritious diet?

Suggestion (1). There are many kinds of food, mainly cereals, and all kinds of food contain different nutrients. No food can supply all the nutrients the human body needs. The daily diet must be properly matched with a variety of foods to meet the human body's demand for various nutrients. Cereal food is the main body of China's traditional diet and the main source of human energy. It provides essential carbohydrates, protein, dietary fiber and B vitamins. Among all kinds of food, cereal is the main food, so pay attention to the collocation of thickness. Recommendation (2). Eat more vegetables, fruits, potatoes, rich in vitamins, minerals, dietary fiber and other bioactive substances. The vitamin content in dark vegetables such as red, yellow and green is higher than that in light vegetables and fruits, while the sugar, organic acids and pectin in fruits are richer than those in vegetables. Diets containing vegetables, fruits and potatoes play an important role in protecting cardiovascular health, enhancing disease resistance and preventing certain cancers. Recommendation (3). Milk that often eats milk, beans or its products contains high calcium, which is the best source of natural calcium and an important source of high-quality protein. Calcium deficiency in the diet of Chinese residents is generally related to the lack of milk and dairy products in the 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 high-quality protein, unsaturated fatty acids, calcium and B vitamins. Eating beans regularly can not only improve the nutritional supply of the diet, but also help prevent the adverse effects caused by eating too much meat. Recommendation (4). Eating proper amount of fish, poultry, eggs and lean meat, and eating less fish, poultry, eggs and lean meat rich in fat and meat are important sources of high-quality protein, fat-soluble vitamins and some minerals. The intake of animal food in quite a few cities and most rural areas in China is insufficient, so the intake of people should be appropriately increased. But residents in some big cities eat too much meat, which is not good for their health. Eat less pork, especially fat and meat oil, and reduce the intake of dietary fat.
