Optimization of dietary structure:

A variety of foods should be consumed to complement each other to achieve the purpose of reasonable nutrition and health promotion. A variety of foods should include five major categories: cereals and potatoes, animal foods, beans and their products, vegetables and fruits, and pure energy foods.

2. Eat more vegetables, fruits and potatoes. Vegetables, fruits and potatoes play a very important role in maintaining cardiovascular health, enhancing disease resistance and preventing certain cancers. You should try to choose darker colors such as red, yellow, and green, but fruits cannot completely replace vegetables.

3. Eat appropriate amounts of fish, poultry, eggs, and lean meat, and eat less fatty meat and meat oil. Excessive intake of fat meat and meat oil is a risk factor for obesity and hyperlipidemia. Pork is the main meat of the Chinese people.
