How Many Major Food Allergens are There?

An allergic reaction is defined as when the body reacts in a hypersensitive fashion to a specific antigen, that is not just identified by the immune system but provokes an immune response as well.

Some people experience allergic reactions not only from cosmetic products, pollen, dust but from food products as well. These allergic reactions are some of the most common.

The allergens that most frequently cause problems are:


The prevalent allergy is that toward milk. Lactose intolerance occurs when the body has a low amount or complete lack of the enzyme lactase, which breaks down lactose. Commonplace symptoms include stomach pains, gas and diarrhea.

Additionally some people have an intolerance to the proteins found in milk, which leads to bronchospasm, swelling, fever, low blood pressure and other problems.

Eggs are an allergen


Eggs are an allergen because they are composed of different proteins. Some of these can be powerful allergens. In some cases, there are allergies to the egg yolk also. The allergic reaction is usually manifested as asthma, allergic rhinitis, dermatitis and others.


Nut allergies are very common. Some people can get an allergic reaction just by eating 2 to 3 peanuts. It is postulated that this reaction is triggered when immune system proteins bind with those found in peanuts.



Undoubtedly this is the most undesirable allergy. Besides the cocoa as an allergen, the different food additives such as milk, soya, eggs, hazelnut or peanut powder can trigger an allergic reaction also. Allergic symptoms to chocolate include irritation and asthma.


Spices are a typical allergen in children especially. A study has shown that about 50% of all children experience allergic reactions to paprika, cumin, dill, sesame, cinnamon, coriander, mustard and others. Of course a dish is a lot tastier with spices but we must keep in mind which ones and how much to use when there are allergic people in the household. A clever trick is to substitute some of the allergenic spices with others while having the taste remain just as tempting.
