Researchers from the University of Arizona studied more than 90,000 post-menopausal women. They found that women ran a 21 percent greater risk of persistent anemia if they didn't get enough of two of the following: iron, folate, vitamin B-12, vitamin C, or the nutrients from red meat.
Women deficient in three of those nutrients were 44 percent more likely to develop anemia. However, the study did not state that a better diet can reduce risk of anemia.
