Quizplus · Accepted Answer

Iron-deficiency anemia is the most common type of nutritional anemia worldwide. It is caused by inadequate intake or poor absorption of dietary iron, which leads to decreased levels of hemoglobin and red blood cells. Megaloblastic anemias due to folate or vitamin B12 deficiency and pernicious anemia due to lack of vitamin B12 absorption are also nutritional anemias, but they are less common than iron-deficiency anemia.
