Tree Nut Allergy Diet

The only treatment for people with food allergies is to avoid the food. Tree nut allergy is one of
the top 8 food allergies in the United States.

Tree nut allergy can be very dangerous. Tree nut proteins may be in foods that you may not
expect. Read food labels well and remember that products may change ingredients without
warning. Always check and recheck all foods, even the “safe” foods you have bought before.
When you eat in a restaurant, explain the restriction clearly to the manager and wait staff, so the
food is not cooked or cross-contaminated with tree nuts.

The Food Allergen and Consumer Protection Act of 2004 requires that foods must list
ingredients by their common names for the top 8 allergenic foods. The top 8 allergenic foods in
the United States are eggs, milk, soy, wheat, peanut, tree nuts, fish, and shellfish.

These ingredients show that the tree nut protein is present:
ξ Almond, almond paste
ξ Brazil nuts
ξ Cashews
ξ Chestnuts
ξ Hazelnuts (also called
filberts or cobnuts)
ξ Lichee nut
ξ Gianduja (mixture of
chocolate and chopped
nuts in imported
ξ Hickory nuts
ξ Macadamia nuts
ξ Marzipan
ξ Nougat
ξ Artificial nuts
ξ Nut butters (cashew,
almond, pistachio, etc)
ξ Nut Oil
ξ Nut paste
ξ Pecans
ξ Pine nuts (pignolia,
ξ Pistachios
ξ Walnuts
ξ Ginko nut
ξ Nangai nuts
ξ Nutella®
ξ Nut meal or nut meat
ξ Shea nut, also known
as Karite
ξ **Coconut

**Coconut, has not been restricted in the diets of people with tree nut allergy. Yet, in October
of 2006, the FDA began to identify coconut as a tree nut. There have been a small number of
allergic reactions to coconut. Most of these reactions though occurred in people who were not
allergic to other tree nuts. Ask your doctor if you need to avoid coconut.

These ingredients may show that tree nuts are present:
ξ Natural extracts, such as almond extract
ξ Barbeque sauces
ξ Ice creams
ξ Nougat
ξ Chili
ξ Chocolate Candies
ξ Cereals or crackers

ξ Ethnic dishes

Cautions and tips
1. Avoid all foods that are made on equipment shared with other nuts. Avoid foods made in
the same place where food products with tree nuts are made. There is a risk of cross
2. Although an allergy to tree nuts is fairly common, some people are very sensitive. Carry
all medicines, including the Epi-pen, if you are traveling or away from home.
3. People who are allergic to tree nuts are sometimes allergic to peanuts as well. Check
with your doctor to confirm which nuts you need to avoid. See info on cross-reactivity,
4. Seeds and other products are often processed at the same location as peanuts or tree nuts.
If you are unsure and the label doesn’t state this, call the food company for more
information. Some companies have separate facilities for their tree nut foods, but some
do not. Examples include M & M candies or Jelly Belly jellybeans.

Tips to follow to prevent an allergic reaction
ξ Avoid foods that cause a reaction. Sometimes just touching foods can cause a severe
reaction. Parents, caregivers and even siblings need to wash hands after eating to avoid
causing a reaction with food particles.
ξ Read the ingredients lists on food labels to make sure foods that cause allergies are not
present. Read the list even if you have had the product before. Ingredients may change.
ξ If you are traveling, bring along some of your own special foods.
ξ When you eat out, always ask restaurant staff about ingredients in food and how it was
prepared. Some cooking oils can have allergens. When in doubt, do not eat it.
ξ For infants, elemental formulas or formulas with altered protein should prevent food
reactions. Talk about the formula options with your doctor or dietitian. Do not assume
products labeled "hypoallergenic" will not cause a reaction.
ξ When you cook clean counters, utensils and pans that have had tree nuts in or on them.
For some people, even touching something that had nuts on it that was not cleaned well,
will cause a reaction.

Cross reactivity
Cross reactivity is when the proteins in one food are similar to the proteins in another food.
Sometimes the body’s immune system sees both proteins as similar to each other. Tree nuts are
not in the same family as peanuts. About 35% of peanut-allergic toddlers will have or develop a
tree nut allergy.

Sometimes doctors will tell you to avoid all tree nuts if allergic to peanuts. Other times doctors
can figure out which tree nuts a child is allergic to, so they can eat certain nuts, but not others.
There is a high degree of cross reactivity with cashew and pistachio and also between walnut and
pecan. Be sure to check with your doctor to figure out which tree nuts to avoid.
