What are the shortcomings of China residents' dietary structure?
First, urban residents consume too much livestock meat and oil, and the consumption of grain is low. The energy supply ratio of fat reaches 35%, exceeding the upper limit of 30% recommended by the World Health Organization. The energy supply ratio of cereals is only 47%, which is obviously lower than the reasonable range of 55%-65%.
Second, the intake of trace elements such as calcium, iron and vitamin A by urban and rural residents is generally insufficient. For example, the average daily intake of calcium per person is 39 1 mg, which is only 4 1% of the recommended intake.
Third, the vegetable intake of urban residents has decreased significantly, and most residents still have not formed the habit of eating fruits regularly. The daily vegetable intake of urban residents decreased from 65438 0.992g to 365438 0.9g to 252g in 2002. In 2002, the daily fruit intake per capita was 45g, slightly higher than that of 1982, but still less than one or two per capita.
The main problem in the quantity of food intake is that the calories consumed greatly exceed the daily metabolism of the body, and the excess calories are converted into fat and stored by the body, so the number of overweight and obese people increases rapidly.
