Why is iron deficiency a problem worldwide? What is the difference between heme-iron and non-heme iron in terms of sources and bioavailability?
A) Iron deficiency is caused by excessive iron intake. Heme-iron is found in plants, while non-heme iron is found in animal products.
B) Iron deficiency is a global issue due to inadequate intake or absorption of iron. Heme-iron is primarily from animal sources and is more readily absorbed than non-heme iron, which comes from plants.
C) Iron deficiency is a rare condition affecting only specific populations. Heme-iron is exclusively found in dairy products, while non-heme iron is found in meat.
D) Iron deficiency is primarily genetic and not influenced by dietary factors. Heme-iron and non-heme iron have similar sources and bioavailability.
