why poor nutrition cause anemia?

Answer 1

The most commonly perceived anemia is due to deficiency of hemoglobin. It is an iron-containing protein. When there is protein and iron deficiency in the diet, it will cause anemia. To add to this I must say that red cell proliferation would be required to have enough RBC loaded with hemoglobin. For cell proliferation you need among other things folic acid, one of the B group of vitamins. So, if the diet is poor in protein, iron and vitamin B, then you will have anemia.

Answer 2

Actually, there are many different types of anemia, and many can be caused by poor nutrition. For instance, a lack of folic acid in the diet can cause anemia because folic acid is required to build purine bases necessary to make DNA and RNA. When the body cannot make DNA and RNA, dividing cells (such as blood cells) cannot form correctly and the person will not have correct numbers of circulating red blood cells (by the way, this will affect the immune system as well). Folic acid is found in green veggies, although it is also added to flour now (called fortified flour) since so many Americans do not eat enough green veggies. Vitamin B deficiencies also can lead to anemia, often caused by feeding babies goats milk instead of human breast milk or formula.

Answer 3

Anemia is, by definition, a lack of iron in the blood. So poor nutrition, eating foods that are low in iron, will cause anemia.

Answer 4

I'm not exactly sure about nutrition but I had anemia due to internal bleeding, was on iron pills for almost a year.
