The endocrine system is a collection of glands and organs that produce and regulate hormones in the bloodstream to control many functions of the body. This system overlaps with the nervous system and exocrine system, and its responsibilities include metabolism, growth and sexual development.
Dried beans and dark green leafy vegetables are especially good sources of iron, even better on a per calorie basis than meat. Iron absorption is increased markedly by eating foods containing vitamin C along with foods containing iron. Vegetarians do not have a higher incidence of iron deficiency than do meat eaters.ortunately, many vegetables, such as broccoli and bok choy, which are high in iron, are also high in vitamin C so that the iron in these foods is very well absorbed. Commonly eaten combinations, such as beans and tomato sauce or stir-fried tofu and broccoli, also result in generous levels of iron absorption.
The best way to prevent it is to eat plenty of whole grains and legumes, along with good sources of vitamin C at meals (citrus fruits, strawberries, peppers, broccoli, leafy greens, cauliflower, cabbage). Vitamin C dramatically improves iron absorption.
