What are the concerns of iron nutrition in vegetarians?
What will be an ideal response?
Overall, about 18 percent of dietary iron is absorbed from mixed diets and only about 10 percent from vegetarian diets. Vegetarian diets do not have the benefit of easy-to-absorb heme iron or the help of the MFP factor in enhancing absorption.
Vegetarians need 1.8 times as much iron to make up for the low bioavailability typical of their diets. Good vegetarian sources of iron include soy foods (such as soybeans and tofu), legumes (such as lentils and kidney beans), nuts (such as cashews and almonds), seeds (such as pumpkin seeds and sunflower seeds), cereals (such as cream of wheat and oatmeal), dried fruit (such as apricots and raisins), vegetables (such as mushrooms and potatoes), and blackstrap molasses.
