How do we get more people to increa their consumption of iron-rich foods? Many nutritionists 21 the increa of a number of foods. This may help, but I contend that we should also intensify our 22 in nutrition education among our young people. I simply do not buy the argument that it is 23 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 24 . As for specific actions, I suggest that blood should be checked as a 25 part of a youngster"s yearly physical examination.
It should contain at least 11 grams iron 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 26 an easily absorbed iron supplement. Adolescents—and everyone el—should cut out highly procesd foods and drinks, which may be 27 in iron and other nutrients. Read the labels for iron content. Especially make sure that all 28 products are made with enriched flour or whole grains.
Try adding liver (chicken, beef or any other variety) to the weekly 29 . Finally, even when you are trying to lo weight, always eat a nsible, well-balanced diet made up of a variety of flesh or very 30 procesd foods. This way, you stand a good chance of getting not only enough iron, but also adequate amounts of all the other esntial nutrients.
