Not all Nut Allergies are Equal

Not all Nut Allergies are Equal

Nuts are quite an amazing food. Packets of energy rich in fat and protein and containing vital vitamins and mineral nutrients, they offer much in every compact serving. Yet as healthy as nuts may be, for many of us, they are simply a pain in the… gut.

Nuts can trigger allergic reactions as well as reactions that are similar to allergies. If your throat swells closed immediately after eating a peanut, you probably have an immediate allergy. As the name implies, immediate allergy is an allergic reaction triggered directly after consumption of a food which is not tolerated.

With a delayed food allergy, hours or days may pass before symptoms appear. For instance, the bloating or diarrhea that you have today could have been triggered by hazelnuts in the nut cake that you ate on the previous day. In this case and cases like it in which you do not have an immediate reaction, the ImuPro blood test – made available in Canada exclusively by FITLabs – will help you determine what is triggering your reaction.

Some types of nuts also play a role in histamine intolerance. The typical symptoms, such as headache, gastrointestinal problems, and skin problems, usually occur a half hour to two hours after eating. If you have this type of intolerance, you should be careful when eating cashews and walnuts.


You should note the following information if you have a nut allergy. It is important to know which processed foods can contain nuts. Be careful with the following items:

  • Trail mixes, snack mixes, muesli
  • Baked goods: nut bread, cake, cookies, fruit bread
  • Fillings in pasta such as tortellini
  • Sliced cheese or meats, salads, pot pies
  • Spreads: nut-nougat creams, vegetarian spreads
  • Sweets: marzipan, nougat, brittles, chocolate, chocolate and muesli bars, pralines, ice cream, pudding
  • Nut oils

Nuts must be declared on all food packaging according to current  regulations. Pay attention to food labels, especially for the words “nut”, “marzipan”, and “nougat”. Also be careful foods that are labeled “may contain...” For non-packaged products, ask the butcher or baker whether the products contain nuts.
