Protein allergies you need to know

Protein is an important nutritional component that the body needs. But in some people, protein can actually backfire on the body that triggers allergic reactions. This condition is called protein allergy.

Basically, protein allergy is a food allergy, an allergic reaction that occurs when a person's immune system overreacts to protein from food consumed. Generally, this condition affects the skin, digestive tract, and respiratory tract. Symptoms of protein allergy can appear suddenly after eating certain foods that contain protein. Apart from food, protein allergies can also occur due to skin contact reactions to certain proteins in animals or plants.

Get to know the source of food that causes protein allergies

All foods that contain protein have the potential to cause allergies in some people. However, there are certain types of foods that are very common to cause allergies. Protein allergy problems that often occur are egg allergies, marine food allergies or seafood such as fish and shrimp, and nuts allergies.

Milk allergy

Milk or food and beverage products that contain milk can cause allergies. Milk allergy occurs when the body's immune system considers protein in milk as a dangerous foreign object, causing an allergic reaction. Sometimes milk allergy is considered the same as lactose or milk intolerance, but both conditions are different.

Egg allergy

Egg allergy is one type of protein allergy that occurs in many children compared to adults. This is an abnormal reaction from a person's immune system to the protein found in eggs. Both egg whites or egg yolks both contain proteins that can trigger allergies. Babies who are still breastfed can also experience a protein allergic reaction if their mothers eat eggs.

Fish allergy

Fish allergy is a type of protein allergy that occurs in many adults. This is an abnormal reaction from a person's immune system to proteins found in certain types of fish, both marine fish and freshwater fish. Fish protein allergic reactions can occur when eating or in contact with fish.

Seafood allergy

This is a protein allergic reaction due to the immune system that overreacts to proteins found in certain seafood, such as shrimp, crabs, oysters, lobsters, squid, and octopus. Symptoms can appear immediately or a few minutes after eating seafood which triggers protein allergies. A person who has seafood allergies can experience allergies to all types of seafood, but can also be allergic to only one or several types of seafood.

Peanut allergies

Protein in nuts can also trigger protein allergies. Various types of nuts can cause allergies, including almonds, pistachios, walnuts, cashews, and peanuts.

Factors that increase your risk of having a food allergy

Certain factors put you at greater risk of having a food allergy.


Food allergies are most common in infants. Allergies of milk, soy, wheat, and eggs can recover from time to time. Allergies to nuts and shellfish are more likely to last a lifetime.

Family history

If asthma, eczema, hives, or fever are part of your family background, you are more likely to have food allergies.

Other allergies

If you are allergic to one food or have other types of allergies, you have a greater risk of food allergies.

Asthma and eczema

Asthma and food allergies often occur side by side. Asthma can also make food allergy symptoms worse.

Food allergies in the past

Although food allergies that develop during childhood can subside because you get older, there is still a chance that allergies can recur later.

Symptoms and Treatment of Protein Allergies

Symptoms of protein allergy arising from eating eggs, fish, seafood, milk and nuts are generally the same, ranging from mild to severe. The reactions that occur include hives and red rashes on the skin, watery eyes and itching, swelling on the lips; disorders of the respiratory tract such as nasal congestion and sneezing; and problems with the digestive tract such as nausea, vomiting, stomach cramps, and diarrhea.

In rare cases, protein allergies can cause a medical emergency called anaphylaxis, with symptoms of coughing, dizziness, decreased consciousness, feeling weak, and swelling in the respiratory tract causing shortness of breath.

Here are some steps for handling protein allergies:

  • The right diagnosis by an immunologist is the main key to dealing with protein allergic conditions. The doctor will perform a physical examination and allergy test.
  • The second step that can be done is to avoid allergens. For example, if you experience allergies after eating eggs, then it is recommended not to consume any eggs and foods that contain eggs.
  • Don't forget to always read the packaging labels for food products that you buy, make sure they do not contain protein in foods that can trigger your allergies.
  • For mild allergic reactions, allergy sufferers can take antihistamine drugs to relieve symptoms. For severe allergies and can cause anaphylaxis, this condition needs to be treated immediately in the hospital.


Given the benefits of protein that is very good for the body, protein allergy sufferers are advised to do immunotherapy or desensitization therapy, to train the body to build a tolerance reaction to protein. Consult a doctor about what steps can be taken to overcome protein allergies without having to avoid the protein sources completely.
