Allergy to Food Proteins

Many people experience allergies related to food. Why do food products produce allergies? This article will clarify the matter.

Food Proteins

Food allergies are related to proteins that are found in the food. The protein in the food causes an allergic reaction. Therefore, the protein in the food is recognized as something dangerous by the immune system in the body. This causes a reaction against the food protein. This reaction can manifest in many different ways.

Symptoms of Food Allergy

Skin problems: Skin is usually affected by developing red, bumpy rashes or eczema. Also redness and swelling around the mouth is a symptom.

Gastrointestinal tract: There can be diarrhea, vomiting and nausea.

Respiratory tract: Runny nose, itchy and watery eyes as well as coughing and sneezing can be symptoms of food allergy.

Anaphylaxis: In a severe allergy there can be life threatening respiratory problems.

What Foods are Likely to contain Allergy Trigger Proteins?

There are several foods that can trigger an allergy. There are many different food allergies based on what kind of protein the body is sensitive to. There are foods that are more likely to cause allergies. Some of these are:

Nuts and peanuts
Fruit such as apple
Seafood such as shellfish

Often the protein causing the allergy is not something found from the food product as such but some extra protein that is carried by the product. This is why hay fever, for instance, can be triggered by eating fruit, which is a carrier for pollen particles. In the case of pollen allergy, it is pollen proteins that cause the allergy.


Avoiding the food in question is the only way to prevent symptoms from occurring. Therefore, it is important to carefully examine the ingredients from which the food you consume consists of. Only by doing this can you eliminate the allergy trigger from your diet and avoid food protein allergy.
