The treatment can only commence after confirming the type of food allergy.

There are four types of food allergy. Let us get discuss about the all types of food allergy here:

The classic food allergy

This type of food allergy can be caused by fish or peanut consumed. The affected person will have immediate swelling of the throat. The affected person must be administered adrenalin injection without wasting any time to revert him back to the normalcy. This kind of classic food allergy can also be brought about by the fruits such as apple, peach, tomato, and celery.

Food intolerance

This is another type of food allergy. This type of allergy is caused by enzyme deficiency and other mechanisms that bring about reactions that are similar to allergic reactions. Here the immune system of the body is not at all involved. This type of allergic reaction may be due to malabsobtion, or reactions of adverse nature created for the naturals chemicals present in the food or due to the coloring and preservative agents present in the food.

Food toxicity

This type pf food allergy is caused by food that contain bacterial toxin or poisoned food. At times toxin [chemical] can also present in the food items for example alkaloids in potatoes. The allergic reactions are as follows. There will be itching and reddening all over the body. The pulse can be rapid.

Food aversion

This is more of psychological than physical. The person believes strongly that particular food items are allergic to him/her. The allergic reaction usually will be vomiting.

As soon as the allergic reactions are noticed the person must be rushed to the near by hospital. The doctor must be briefed about the food that was consumed by the person. This will help the doctor to identify the type of food allergy, thus helping him to choose the right treatment.

Few examples of allergic foods tree nuts such as hazelnut, Brazil nut, walnuts, almonds, cashew, pistachio etc can lead to allergy. Apple, peach, strawberry can cause allergic reactions in case of fruits. In case of vegetables tomatoes, potatoes, parsley and celery can cause food allergy.

As per general observation as much as 15% of the people must have suffered from some sort of food allergy at least one time in their life time. Some people, when they know that they are allergic to some food item, instead of reporting it to the doctor and get cured, they just try to avoid the food from consuming. This is very wrong practice.
