Urgent! ..... Talk about the advantages and disadvantages of China's diet structure. Great, please help me!

The current dietary structure of China people is not only determined by the current economic living standard, the balance between population and agricultural resources, but also the accumulation of people's dietary life experience for thousands of years. With the development of social production, people's living standards have been generally improved, but the problems of undernutrition and overnutrition caused by the evolution of dietary structure have become increasingly prominent, that is, "malnutrition and overnutrition coexist, and poverty and prosperity coexist". But on the whole, the dietary structure in China still belongs to the dietary type with plant food as the main food and animal food as the supplement.

(1) Advantages

① The dietary structure is dominated by plant foods, among which cereals account for a large proportion. Because of the high carbohydrate content in cereals, carbohydrates are the most economical and main source of heat energy.

The intake of vegetables and coarse grains makes people consume a lot of dietary fiber, so the incidence of digestive system diseases and intestinal cancer is extremely low.

(2) Disadvantages

① The low content of animal food and legume food makes the supply of a few minerals and vitamins insufficient, such as calcium, iron, riboflavin and vitamin A; Although the supply of heat energy and protein basically meets the demand, the utilization rate of protein is not ideal.

② Lack of lean beef, lean mutton, fish and other animal foods leads to insufficient intake of high-quality protein.

② The salt intake is too high, and some unscientific and uncivilized eating habits still exist. The average daily salt intake of Chinese residents is 13.5g, which is far from the standard that the average daily salt intake per person is less than 6g proposed by the World Health Organization in the Recommendations for Prevention and Treatment of Hypertension and Coronary Heart Disease.
