Anemia, or iron deficiency, is common in people who have type 1 and type 2 diabetes, research says. Iron overload, or hemochromatosis, is also common among people with type 2 diabetes, according to research, so it’s important to test your levels before changing your diet. If you have iron-deficiency anemia, your healthcare team will advise you to incorporate iron-rich foods into your diet to ensure your iron levels remain within the recommended range. Many foods that contain iron are nutritious in other ways and provide other health benefits while lowering your risk of anemia. One-half cup of beans (fresh, after soaking, or from the can) is considered one serving, according to the U.S. Department of Agriculture (USDA).
