With a peanut or tree nut allergy, even a tiny amount ingested or inhaled could cause an allergic reaction. Some of the places you find nuts, like nut butters and nut breads, are not surprising. Others -- like sauces and gravies -- may be.
Once you know what to look for, you can check labels carefully before you buy or use a product.

4 Tips for Avoiding Nuts
Beware of cross-contact. Foods that don't contain peanuts or tree nuts can get contaminated if they are prepared in the same place or using the same equipment. Foods sold in the U.S. must say this on the label. Cross-contamination also occurs in ice cream parlors because of shared scoopers and other equipment, as well as in many ethnic restaurants where a wide variety of ingredients are used.
Check the label each time you buy a product. Manufacturers sometimes change recipes, and a trigger food may be added to the new one.
Look for peanuts outside the kitchen. In addition to foods, nuts can be in lotions, shampoos, and pet food. Check labels before you buy or use them.
Carry an epinephrine autoinjector. Carry two with you at all times and know how to inject it. For some people, an allergic reaction to nuts can quickly become life-threatening, so always be prepared. Brands includeEpiPen, Emerade, Twinject, Adrenaclick, Anapen, Jext, Allerject, and Auvi-Q.
