TEXT B How do we get more young people to increase their consumption of iron-rich foods Many nutritionists are advocating the fortification of a number of foods. This may help, but I contend that we should also intensify our efforts in nutrition education among our young people. I simply do not buy the argument that it is futile to try to change eating habits. Once an intelligent person—and this includes adolescents—understands the need for a healthy diet, I think he or she will act accordingly. As for specific actions, I suggest that blood hemoglobin should be checked as a routine part of a youngster’s yearly physical checkup. It should contain at least 11 grams per 100 milliliters of blood for a girl and at least 12 grams for a boy. If it is any lower, the physician probably will prescribe an easily absorbed iron supplement. Adolescents—and everyone else—should cut out highly processed foods and drinks, which may be low in iron and other nutrients. Read the labels for iron content. Especially make sure that all bakery products are made with enriched flour or whole grains. Try adding liver, chicken, beef, veal or any other variety to the weekly menu. Finally, even when you are trying to lose weight, always eat a sensible, well-balanced diet made up of a variety of fresh or very lightly processed foods. In this way, you stand a good chance of getting not only enough iron, but also adequate amounts of all the other essential nutrients. The passage is mainly about ______.

A. the importance of diet
B. the need of iron
C. adolescents eating habits
D. blood hemoglobin
