Knowing which foods trigger food allergies and avoiding those foods is the best way to prevent allergic reactions. Unfortunately, food allergens are often "hidden" in sauces, ice creams, baked goods, and other items. If you have food allergies, read food labels carefully. Be aware of other names for food allergens, such as "caseinate" for milk or "albumin" for eggs. Many people think that seeing "nondairy" on a label means there is no milk in the product. This is not necessarily true.

Sometimes products are recalled when food ingredients are missing from food labels. For a list of recalled products, see the U.S. Food and Drug Administration's Recalls, Market Withdrawals, and Safety Alerts page at www.fda.gov/opacom/7alerts.html.

Eating out can be dangerous for people with severe food allergies. Here are some tips:

• Bring safe substitutes from home. For example, bring soy milk to have with cereal.
• Be aware of possible cross-contamination. For example, an ice cream scoop may have been used for Rocky Road ice cream, which contains peanuts, and then used for your vanilla ice cream.
• Alert the wait staff to the possibility of a severe food reaction. Carefully question them about ingredients. If they are not sure, ask to speak to kitchen staff.
• Always wear medical alert jewelry that lists your food allergies. Medical alert jewelry can be ordered through most pharmacies or on the Internet.

If you or your child has ever had a severe allergic reaction, always carry an allergy kit that contains a syringe of epinephrine and antihistamine tablets. Give the epinephrine shot as soon as you or your child feels a reaction starting. Then take the antihistamine. For more information about the shot, see:

Allergies: Giving yourself an epinephrine shot.

If you are traveling to another country, learn the words for the foods that trigger your allergy so that you can ask in restaurants and read food labels. Call airlines, tour operators, and restaurants ahead of time to explain your food allergy and request safe meals. Prepare your own food when possible. Discuss your travel plans with your doctor.
