Anemia occurs when your blood has a lower than normal number of red blood cells.
In order to lower their risk for anemia, women need to get enough of two of the following: iron, folate, vitamin B12, vitamin C, or the nutrients from red meat. Women who were deficient in at least three of those were even more likely to develop anemia.
The research was done at the University of Arizona, with information from more than 90,000 women.
