All about food allergies

There is a lot to say on this subject so let’s start with what is what and why is this happening to us.  

Food allergy is an abnormally strong immune system reaction to proteins in our food. It is a form of food hypersensitivity. Can occur instantly, within seconds or in a few hours.  It is not food poisoning.

Food intolerance is when the reaction happens later and it lasts longer and it’s just uncomfortable. It happens when your body has difficulty digesting. 

Allergens- the substance (antigen) that leads to the response of the immune system. They are the allergy triggers . 

Histamine- an organic substance that is responsible for starting the process of getting rid of the allergens from your body. They make you sneeze, itch, have a runny nose or tear up. The amount that you need varies from person to person. 

Cross-reactivity is when the proteins of different allergens are so similar that the body can not distinguish between them.


  1. Hereditary- runs in the family 
  2. Sensibilization – prolonged exposure to allergens

In The Netherlands there are 14 allergens that are required by law. I am amusing those because I found them to be the main categories that are creating problems, food wise. Other allergens are pet or pollen, but we are not discussing them. 

In children you can mostly see an allergic reaction to: milk, eggs, fish and nuts.

In adults you can see reactions to: nuts, fish, gluten and soy. A high number of adults that are lactose intolerant.

In really unlucky people they can have an allergy to almost all the ingredients and for that I am sorry. 


They vary as well.

 The face, lips, tongue or eyelids can swell or itch. (O.A.S= oral allergy syndrome)

You can have a stuffy nose, shortness of breath. 

You can experience a rash, vomiting or diarrhea. 

In severe cases people need an adrenaline injection because they enter an anaphylactic shock that if not treated can cause death. 

Dealing with allergens 

Prepare your food carefully and be mindful of cross- contamination. 

Communicate your food and dietary restrictions. 

You will find here info about:

Gluten allergy 

Gluten sensitivity is a common intestinal condition. Having a coeliac disease is not an allergic condition.

Found in: grains, wheat, barley, rye, oats, spelt, kamut.

Possible cross-reactivity with: milk, corn, rice, yeast 

Symptoms of the allergy: bloated belly, abdominal pain, vomiting, less appetite, persistent diarrhea, stinky greasy stool. 

Egg allergy

Some people can eat cooked eggs because the proteins are broken during the cooking process but that doesn’t mean that your allergy is gone. 

Possible cross-reactivity with: other egg types, meat. 

Symptoms of the allergy: audible breathing, asthma like symptoms, abdominal pain, vomiting, cramps, diarrhea or constipation. Can induce an anaphylactic shock. 

Fish allergy 

The protein from fish that is causing all those nasty symptoms is very heat stable so cooking it will not help.

Possible cross-reactivity with: other fish species. No cross-reaction with crustaceans, squid, snails or caviar. 

Symptoms of the allergy : gastrointestinal complaints, respiratory problems, skin rashes, an anaphylaxis shock may occur, angioedema( a swelling or accumulation of fluid that occurs in a short period of time, mostly encountered in face, tongue, intestines or throat).

Peanut allergy

Also known as earth nut, groundnut, oil nut or monkey nut. That is actually not a nut, it is a bean. 

This is a life threatening allergy. The reaction to this can be so strong and quick, if a quick action is not taken it may end in death. And who wants to tell close ones that their dear relative died from a peanut.

Possible cross-reactivity with: soy, peas, lentils, lupin, beans, birch pollen. 

Symptoms of the allergy: most commonly they involve skin complaints. You can also hear about angioedema or respiratory problems.

Nuts allergy 

Reacts to hazelnuts, walnuts, cashew nuts, pistachios, macadamia nuts, pecan nuts or seeds such as almonds. Now this is a long list of things that you can’t have. 

Possible cross-reactivity with: other nuts and birch pollen.

Symptoms of the allergy: to itch around the mouth.

Soy allergy 

It is a common food allergy.

Possible cross-reactivitywith: other nuts and peanuts.

Milk allergy 

Most common is the allergy to cow’s milk but this doesn’t mean lactose intolerance. To be lactose intolerant it means that you can tolerate the proteins but can’t digest the lactose properly. 

Possible cross-reactivity with: other types of milk. 

Symptoms of the allergy. hives, itching or tingling feeling around the mouth, swelling of the lips, tongue or throat, shortness of breath, vomiting. 

Crustaceans allergy

Includes crab, shrimp or river lobster. It usually takes around one hour to make an appearance.

Contact, inhalation of steam during preparation or contaminated oil can cause a reaction.

Possible cross-reactivity with:birch and or mugwort pollen 

Symptoms of the allergy: gastrointestinal complaints,  O.A.S= oral allergy syndrome.

Mustard allergy

Sesame seeds  allergy 

It is also categorized as a severe allergy.
