Fruits, Vegetables, Grains, Nuts, Meat, Poultry, and Fish
Eating a healthy diet is always a wise idea -- especially during pregnancy. It's also a good idea during pregnancy to take a prenatal vitamin to help cover any nutritional gaps in the mother's diet. Prenatal vitamins contain many vitamins and minerals. Their folic acid, iron, iodine, and calcium are especially important.  Iron helps produce hemoglobin, the protein in red blood cells that carries oxygen to your body's tissues. There are two kinds of iron: heme iron is found in red meats, fish and poultry, and is better-absorbed than non-heme iron, which is found in enriched cereals, leafy veggies and raisins. It's found in everything from raisins to red meat, such as liver. Other good sources of iron are fish, eggs, beans and leafy green vegetables, like spinach and lettuce. Eating breakfast is a great way to fill up on iron-try an iron-enriched cereal, such as bran flakes, and add raisins for sweetness and flavor. A multivitamin is a preparation intended to be a dietary supplement with vitamins, dietary minerals, and other nutritional elements. Such preparations are available in the form of tablets, capsules, pastilles, powders, liquids, and injectable formulations.  Dietary iron has two main forms: heme and nonheme [ 1 ]. Plants and iron-fortified foods contain nonheme iron only, whereas meat, seafood, and poultry contain both heme and nonheme iron [ 2 ]. Heme iron, which is formed when iron combines with protoporphyrin IX, contributes about 10% to 15% of total iron intakes in western populations [ 3-5 ]. Iron is an essential component of hemoglobin, an erythrocyte protein that transfers oxygen from the lungs to the tissues [ 1 ]. As a component of myoglobin, a protein that provides oxygen to muscles, iron supports metabolism [ 2 ]. Plant and meat foods can be a good source of iron. Iron from meat (heme iron) is more easily absorbed than iron from plants (nonheme iron). Iron is absorbed in our intestines; absorption is greatly improved by taking vitamin C. Some foods, for example dark leafy greens, contain both iron and vitamin C. Eating meat boosts iron absorption when we eat leaves and vegetables.  Unlike calcium, which is already found in your body, iron can only be obtained from food. It's found in everything from raisins to red meat, such as liver. Other good sources of iron are fish, eggs, beans and leafy green vegetables, like spinach and lettuce. Eating breakfast is a great way to fill up on iron-try an iron-enriched cereal, such as bran flakes, and add raisins for sweetness and flavor. Iron is a mineral that is naturally present in many foods, added to some food products, and available as a dietary supplement. Iron is an essential component of hemoglobin, an erythrocyte protein that transfers oxygen from the lungs to the tissues [ 1 ]. As a component of myoglobin, a protein that provides oxygen to muscles, iron supports metabolism [ 2 ]. Iron is an essential nutrient because it is a central part of hemoglobin, which carries oxygen in the blood. Iron deficiency anemia is a worldwide health problem that is especially common in young women and in children. Iron is found in food in two forms, heme and non-heme iron. Heme iron, which makes up 40 percent of the iron in meat, poultry, and fish, is well absorbed. Non-heme iron, 60 percent of the iron in animal tissue and all the iron in plants (fruits, vegetables, grains, nuts) is less well absorbed. Because vegan diets only contain non-heme iron, vegans should be especially aware of foods that are high in iron and techniques that can promote iron absorption.
