    Soy Allergies: Spotting Problems on Food Labels

    Soy can show up in lots of foods, so if you're allergic to it, look at the package carefully. All packaged foods have to show on the label that they contain milk, eggs, fish, shellfish, tree nuts, peanuts, wheat, or soybeans.

    If the label says "Contains: Soy," it's a no-brainer: don't add it to your shopping cart! But also look at the ingredients list. There are lots of different ways to say "soy."

    Allergy Tips: Your Outdoor Exercise Checklist

    If you have allergies, you might feel like outdoor exercise detracts from your health more than it adds. Exercise is supposed to make you feel good. But if a quick jog or a bike ride leaves you wheezing, sneezing, and feeling miserable for hours afterwards, how healthy can it be? But all of us -- allergic or not -- need to exercise regularly for our overall health. And the good news is that you can, even if you're exposed to outdoor allergens. "People with allergies and asthma should be able to...

    You'll find it in a lot of foods. Be on the lookout for these:

    • Baked goods, which may use soybean flour
    • Vegetable oil
    • Vitamin E
    • Meat products, such as sausages and hamburgers

    • Low-fat peanut butter
    • Salad dressings, mayonnaise, gravy, and sauces

    How to Choose Safe Foods

    Stick with packaged and labeled foods. Foods from salad bars, deli counters, and bakeries are more likely to have something made from soy.

    Read food labels every time you buy a product. Food manufacturers often change ingredients. Something that's one of your favorites could suddenly have soy in it. So be on your guard.

    Be careful about ingredients that you're not familiar with. Follow a simple rule: When in doubt, look it up. You can email the maker of the product if you're still not sure about something.

    Watch out for different types of a product. Low-fat or reduced-calorie versions of familiar foods may have different ingredients. Sizing (like snack-sized packs) or packaging (a can vs. a carton) can also affect what's inside. Some products may have different ingredients in different parts of the country.
