Diets High in Iron Are Necessary for Pregnant Women

March 19, 1987|TONI TIPTON

Even with today's interest in health and fitness, there are still those who have not jumped on the health-food bandwagon. But usually when women find out they are pregnant, good nutrition becomes the foremost issue in their lives. The responsibility of nurturing another human being apparently brings out the best eating habits in pregnant women and nursing mothers. They give up smoking, cut back on caffeine and look to foods that provide optimal nutritional benefit.

Increasing iron in the diet is a high nutritional concern during this time. Improving iron supplies during pregnancy, according to Rita Storey, media representative and spokeswoman for the American Dietetic Assn., is a necessity since additional blood will be used in building and nurturing the new life--in the formation of fetal, placental and maternal tissues.

For the mother, it is a requirement because her body will develop a reserve of hemoglobin to stave off anemia during high-volume blood losses, such as when the baby is delivered.

In the body, hemoglobin is the principal component of the red blood cells. It accounts for most of the iron found in the body, and its purpose is to carry oxygen from the lungs to the tissues.

Absorption Rate Varies

The rate at which the body absorbs iron from food varies depending upon the type of iron consumed--heme, derived from meat, fish and poultry in which the iron is part of a protein, and non-heme, present in foods such as milk, eggs and plant products. (Growing children, pregnant women and anemic individuals have a higher rate of absorption than healthy males; therefore, their needs are greater.)

The composition of the rest of the meal and the status of the individual's iron stores are also major influences. Some factors that have an inhibiting effect on the body's absorption of iron are tannins from tea, phytates from cereals (phytate is a phosphorus-containing organic compound that decreases mineral absorption) and antacids.

The Recommended Dietary Allowance for adult males is 10 milligrams, and for females the figure jumps to 18 milligrams. Some good food sources include meat, fish, poultry, and especially liver, whole-grain and enriched cereals, legumes, green leafy vegetables, eggs and dried fruit.

Meat, fish and poultry are considered superior sources because the iron in those foods is easily absorbed, whereas the cereal products and certain vegetables--especially peas and deep green leafy vegetables--have significant amounts but they are not absorbed as readily.

Other Good Sources

Prunes are also an excellent source. Ten pitted prunes contain four milligrams of iron, second only to one slice of beef liver, which contains 7.5 milligrams. One cup of chopped raw spinach offers 1.7 milligrams, one cup of cooked oatmeal has 1.4 milligrams and 10 dried uncooked apricot halves have 1.9 milligrams.

The recipes that follow are designed to supplement an iron-conscious diet. None will exclusively provide the required daily amount.

"It is possible to get this amount (18 milligrams) from food," Storey said, "but probably 99% of the time prenatal supplements are prescribed because it's difficult to get these foods in the diet every day. That's why prenatal counseling by a registered dietitian is so important. . . . Then they (pregnant women) are apprised of what the principal nutrients are."
