what nutrients contain iron
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.ron is an essential nutrient because it is a central part of hemoglobin, which carries oxygen in the blood.
