These foods also inhibit absorption. Vitamin C, found in citrus fruits, cantaloupe, strawberries, leafy greens, broccoli and bell peppers, increases absorption -- so eat these veggies and fruits together with those containing iron. Beans and legumes are veggies rich in iron. A cup of canned white beans contains 8 milligrams, 1/2 cup of lentils contains 3 milligrams and 1/2 cup of kidney beans or chickpeas contains 2 milligrams. A 1/2-cup serving of cooked spinach provides 3 milligrams, while 1/2 cup of tomatoes offers 2 milligrams.
