A Blind Zone in Childr-Nutrition
This article reveals a mistaken idea in child-raising which deserves correcting. Most parents take it for granted that children should eat more animal foods such as chicken, meat and fish than grain food because the former are far more expensive and the more expensive the food is the more nutritious it is. However, this is, in fact, a mistaken idea which has lead to malnutrition among many city kids. This is indicated in a survey recently made in Shanghai.
What parents don’t know is that carbohydrate in grains, starch and sugar, the main and most inexpensive nutrient for energy supply, is of equal importance in metabolism. The energy it supplies is the main source of calories in human bodies,about 60% of the total amount of calories. If there is a lack of calories provided by carbohydrate, protein and fat will be used up to provide the heat and thus can’t play their original roles in the body. Consequently, it results in a retarded development in the children and even malnutrition.
Apparently, the solution to the problem is to provide kids with a well-balanced food containing protein, carbohydrate and many other nutrients, none of which can be done without.
