[-1:-3.00]While active, child-bearing age women
[-1:-4.00]are most likely to have low iron stores,he notes,
[-1:-5.00]"Men are not safe,
[-1:-6.00]especially if they don't eat meat and have a high level of physical activity."
[-1:-7.00](An estimated 15 percent of male long distance runners have low iron stores.)
[-1:-8.00]Beard and other experts say
[-1:-9.00]it's advisable for people in these groups
[-1:10.00]to have a yearly blood test to check blood iron reserves.
[-1:11.00]10  If iron levels are low,
[-1:12.00]talk with a physician to see if the deficiency should be corrected
[-1:13.00]by modifying your diet or by taking supplements.
[-1:14.00]In general, it's better to undo the problem
[-1:15.00]by adding more iron-rich foods to the diet,
[-1:16.00]because iron supplements can have serious shortcomings.
[-1:17.00]Supplements may produce a feeling of wanting to throw up,
[-1:18.00]and may be poisonous in some cases.
[-1:19.00]The best sources of iron,
[-1:20.00]and the only sources of the form of iron most readily absorbed by the body,
[-1:21.00]are meat, chicken, and fish.
[-1:22.00]Good sources of other forms of iron include dates,
[-1:23.00]beans, and some leafy green vegetables.
[-1:24.00]11  "Select breads and cereals with the words 'iron-added' on the label,"
[-1:25.00]writes sports diet expert Nancy Clark.
[-1:26.00]"This added iron supplements the small amount that naturally occurs in grains.
[-1:27.00]Eat these foods with plentiful Vitamin C
[-1:28.00](for example, drink orange juice with cereal
[-1:29.00]or put a tomato on a sandwich) to enhance the amount of iron absorbed."
[-1:30.00]Clark also recommends cooking in iron pans,
[-1:31.00]as food can derive iron from the pan during the cooking process.
[-1:32.00]"The iron content of tomato sauce
[-1:33.00]cooked in an iron pot for three hours showed a striking increase,
[-1:34.00]the level going up nearly 30 times," she writes.
[-1:35.00]And people who are likely to have low iron
[-1:36.00]should avoid drinking coffee or tea with meals,she says,
[-1:37.00]since substances in these drinks
[-1:38.00]can interfere with iron being absorbed into the body.
[-1:39.00]12  "Active women need to be a lot more careful about their food choices,"
[-1:40.00]sums up Purdue's Lyle.
[-1:41.00]"If you pay attention to warning signs before iron reserves are gone,
[-1:42.00]you can remedy the deficiency before it really becomes a problem."
