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.
