Recommendation (2). Eat more vegetables, fruits and potatoes.

Vegetables, fruits and potatoes are 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). Often eat milk, beans or their products.

Milk 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). Eat fish, poultry, eggs and lean meat, and eat less fat and meat oil.

Fish, poultry, eggs and lean 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.
