Vegans can get sufficient iron from plants by eating those high in iron and eating foods like fortified cereals. Iron absorption will increase with the consumption of foods high in vitamin C at the same meal. To optimize iron consumption, grains and beans can be soaked to lessen phytate content. Tannins, antacids and soda should be avoided and calcium supplements should not be taken at mealtime.
Raw food vegans (especially pregnant women or women of childbearing age) may have a harder time getting sufficient iron, especially if on a 100% raw food diet. If you are 80% raw or less, consider supplementing your diet with high iron foods like cooked beans and taking all of the other precautions listed above.
Men and post-menopausal women should be careful not to supplement or eat too many iron-fortified foods unless they have iron deficiency anemia.
