There are several different kinds of allergy, but perhaps the most common is Food allergy. As its name suggests, this type of allergy is triggered when a reaction occurs after contact with a particular food to which you are sensitized. ‘Sensitized’ means that you have taken this food before.

As the food enters the body, your immune system – your body’s natural defense – sees the food substance as harmful foreign substance and mounts an attack against the protein. It produces a specific type of antibodies called IgE to “fight off” the proteins. This action of your own body’s immune system is what triggers an allergic response.


The symptoms of food allergy could range from mildly inconvenient to uncomfortable to complete collapse of the body, a condition known as anaphylaxis. Many people have died or have been brought to emergency rooms as a result of anaphylaxis brought about by violent allergic reactions to certain types of food.

Common signs of food allergy include the following:

• Tingling sensation in the mouth

• Swelling of the tongue and the throat

• Difficulty breathing

• Hives

• Vomiting

• Abdominal cramps

• Diarrhoea

• Drop in blood pressure

• Loss of consciousness

• Death (extreme cases)

Typically, these symptoms appear within minutes or two hours after the person has eaten the food he or she is allergic to.

The response can range from mild or moderate to severe, including symptoms like swelling of the face and tongue, rash called “hives” (like nettle rash), breathing difficulties, runny nose and eyes, swelling of the throat, abdominal pain and bowel disturbances, nausea and vomiting and could to life-threatening collapse (anaphylaxis).

Below are some practical tips to help you manage food allergy:

You may also consult your dietician and discuss or ask for any advice/help about special dietary alternatives or recipes that won’t trigger your allergy. Also, try your local libraries for recipes or contact allergy specialists for more information on sensitivities or recipes.

If you are eating out, telephone the host or chef in advance and explain your needs. See if they will allow you to supply your own food. If not, perhaps they can adapt the menu for you. Always make it a point to discuss everything beforehand so you won’t get tempted to eat anything you shouldn’t.

Take extra supplies

Whenever you go out. You might take longer than you originally planned so carrying a spare packed lunch or goodies with you can be a big help not only to stave off your hunger but also to keep you away from restaurants selling foods that may trigger your food allergy.

Avoidance Method

Having food allergies doesn’t mean that you ought to stop eating foods that you are otherwise not allergic to. Just because you think you’re allergic to something doesn’t mean that you really are allergic. Taking food out of your diet could result in an unbalanced diet, which could lead to other health problems. In addition, you may reach a point where you become frustrated because you think that everything you eat causes food allergies.

By avoidance, we don’t mean complete avoidance of foods. Try to keep a food diary where you make a list of all the foods that you’ve eaten for the day and whether or not you suffered any allergies as a result. The information you garner from your list could help you determine exactly what foods trigger what, and could also give your doctor important information about your food allergies.
