The Most Common Food Allergies
(The Top 8)

The most common food allergies are dairy, egg, wheat, soy, peanuts, tree nuts, fish and shellfish, though, allergic reactions can be caused by virtually any food.

These foods are often referred to as "The Top 8" or "The Big 8" because  they are the cause of 90% of all food allergic reactions.

Because they are the most common food allergens, food manufacturers regulated by the U.S. FDA must clearly state if a food contains these foods or ingredients derived from them.

How to Avoid Your Allergens

Common food allergies

Read Labels

The Food Allergen Labeling Consumer Protection Act  of 2004 (otherwise known as FALCPA) requires that foods regulated by the U.S. Food and Drug Administration clearly indicate if a product contains any of the top 8 allergens.

This can be done in two ways.  The first way is shown below.  The allergen is stated in plain English next to the ingredient that contains that allergen...

Ingredients: Enriched flour (wheat flour, malted barley, niacin, reduced iron, thiamin mononitrate, riboflavin, folic acid), sugar, partially hydrogenated soybean oil, and/or cottonseed oil, high fructose corn syrup, whey (milk)eggs, vanilla, natural and artificial flavoring) salt, leavening (sodium acid pyrophosphate, monocalcium phosphate), lecithin (soy), mono-and diglycerides (emulsifier)

The other way is to list the allergens at the end of the ingredient list like this...

Contains Wheat, Milk, Egg, and Soy

Also, ingredient lists should list specific types of tree nuts (i.e. almonds, cashews, etc.), fish (i.e. flounder, cod, etc.) and crustacean shellfish (i.e. shrimp, crab, etc.)


What about those "May Contain..." statements?

These "advisory statements" are not required by the FDA, however, they should not be ignored.

In December 2010, the National Institute of Allergy and Infectious Diseases put out a summary of the expert panel's Guidelines for the Diagnosis and Management of Food Allergy in the United States.  

In the guidelines, the expert panel recommends avoiding foods containing advisory statements.

Some Foods Are Exempt from FALCPA

  • Foods that are exempt from the FALCPA law include:
  • Raw agricultural commodities (such as fresh fruits and vegetables)
  • Highly refined oils derived from the top food allergens
  • Any ingredient derived from highly refined oil

Note that expeller pressed and cold pressed oils are not exempt as they could still contain allergen proteins.

Read Labels Every Time!

It might seem like an inconvenience to read labels every single time but it is very important in the management of food allergies.

That's because ingredients can change and packaging can stay the same.  

Also, the appearance of "safe" foods and that of allergenic foods can be very similar.  

Take a look at the tortilla packages to the right.  They look very similar but one is gluten free and the other is low carb.  Careful label reading is the key to accidental exposure to allergens.

And if there isn't a label, the food should be avoided.

Avoid Cross Contamination

You are probably familiar with the term "cross-contamination" which is one of the causes of food borne illness (food poisoning). To prevent food poisoning, cooks are advised to keep raw foods, especially meats, away from cooked and ready-to-eat foods. This is because pathogens from raw foods can be moved to the cooked foods and ultimately make the person eating it sick.

Why the food safety 101 lesson? Well, the same care must be taken when preparing foods for people with food allergies. Just think of the allergen as the "raw food" or an even more vivid picture, a nice, big, raw chicken breast in all of its salmonella covered glory. Not something you want touching the rest of your food!

Here are some tips for avoiding cross-contamination when eating with food allergies:

Wash all utensils with soap and water before and after handling food allergen(s).  This includes pots, pans, knives, stirring spoons, cutting boards, etc. Many people may think it is good enough to just "wipe off" utensils.  Unfortunately, this is a very common mistake.  If you're trying to explain it someone and they're not getting it, use the raw chicken analogy. 

Wash all surfaces where foods containing food allergen(s) were prepared with soap and water

This one goes right along with the utensils. Again, treat the allergen(s) the way you would raw foods to avoid cross-contamination.

Wash hands often

You  really can't go wrong with good hand washing habits.

Avoid the allergen altogether

This will depend on a few factors.  If an allergen causes a serious reaction, you might decide to ban it from your house altogether.  Both of my sons are allergic to eggs (one of them anaphylactic) so we usually don't have eggs in our house.  Very rarely we will have them but they are handled with care.  We clean utensils, bowls and pans very well after cooking them and are careful about what we touch and cleaning surfaces that might have come into contact with them.  That works for us.  You have to figure out what works for you.

Contact Food Manufacturers

Even though FALCPA requires that the most common food allergens (the top 8) are clearly identified on food labels, there are still times when the label doesn't tell the whole story.

Cross-contamination during production of a food is one reason to contact the manufacturer of a food.   Many foods come in different varieties (plain, cheesy, buttered, nutty, etc). You might purchase the plain one thinking they are safe because the label doesn't list any of your allergens but they might be made on the same line as the variety containing the allergens you're avoiding.

Some companies do this and have very strict rules about cleaning the line in between different products and even testing the line to be sure it doesn't contain allergens. Others may not take such care.

Companies are not required to make "advisory statements" such as "may contain traces of...", if a food is manufactured near common food allergens.  Therefore, you will need to determine what degree of risk you are comfortable with when purchasing foods.


Find Your Comfort Zone

As you gather information and gain experience managing the food allergies that you are dealing with, you will gradually become more and more comfortable (really!).

One way to do this is to get some support.  You can find support groups online and local groups in your area.  The main thing is that you have others with similar challenges that you can bounce questions off of and share your experiences with as well.

Even if you don't have one of the most common food allergies (maybe you're allergic to corn or sesame), you can find others who are dealing with the same thing.  Support is a key piece in the food allergy puzzle.

Your comfort zone will probably change as time goes on. It will dictate many things in your everyday life including:

  • Whether you contact food manufacturers about cross contamination possibilities
  • Whether you have foods containing your food allergens
  • Whether you go to a family gathering where foods containing your allergens will be (this may sound extreme but some food allergies are just that serious).

Above all, always remember to trust your instincts. Don't let anybody make you feel as though you are making a big deal out of nothing. Food allergies can be very serious and you know what you need to do to keep yourself or your child healthy. Find your comfort zone and trust it!
