FOOD ALLERGIES ON THE RISE: What is food allergy? How the body responds to it?
Food allergy is a kind of allergy caused due to the reaction of the body against foreign materials found in food products.
The body’s immune system acts against these unhealthy foreign particles causing allergic reactions. So, to trap these foreign particles, the immune system releases chemicals.

- Itching over a specific body part or over whole body
- Redness over skin or body
- Drop in blood pressure
- Fluctuations in heart beat

How to know if you are allergic to a food item?
In most of the cases the symptoms produced by the food items are sufficient to know if you are allergic to it. Sometimes, these symptoms are produced immediately i.e. within minutes and sometimes they take some hours (1-2) to develop. In any case, symptoms are the initial way to know the food allergy(FOOD ALLERGIES ON THE RISE).
Sometimes, symptoms are not sufficient to prove if you are allergic to food item. You can confirm it through skin prick food allergy test. In such test, the food item or liquid is tested in very less amount over the skin which is then slightly pricked. After 15-20 minutes, if redness or bump appears on that area over skin, then, you are considered allergic to that food stuff.
How food allergies are rising?
FOOD ALLERGIES ON THE RISE: As told by the doctors, food allergies are rising among human population. It has been observed from the surveys that food allergies have increased up to 50% among children from 1997 till 2011. There are many reasons behind this scenario. Some are:
- Limited exposures to infectious agents in childhood, as people are being too clean. This makes the immune system develop in that way. When children are exposed to even small amount of germs, they get the allergies as their immune system take small amount of germs as big foreign invaders. This is also termed as hygiene hypothesis.
- Environmental changes: As the environment is becoming warmer day-by-day, it gives to the development of germs more easily. More is the development of germs; easy will be the decomposition of food. This also gives rise to food allergies.
- Overuse of antibiotics related to stomach. This causes the alteration in gastrointestinal tract making the stomach more susceptible to health problems even at small exposure to germs.
These three reasons are the most commonly studied ones. They clear the picture of rise in food allergies very much.
HOW TO TREAT FOOD ALLERGY?
There is no permanent treatment of food allergies. It is just that when you get the allergy, you can take medicine or injection for improving the symptoms.
Some people say that when they start eating food items in very small item to which they are allergic, they develop immunity for such foods. This is the same case which happens in vaccination. But most of the doctors don’t agree with this as this theory does not go with all the human population. Some people develop immunity in such cases and some not. Those people who become unable to develop immunity might face the health consequences. So, they suggest not following the theory.
The best treatment is avoiding the food item you are allergic to. Your life is more important than food.
Or you may supplements such as GRECOBE , which has antioxidants known as polyphenols in the form of chlorogenic acid which might be effective to boost the immune system to fight against various diseases originate due to free radicals.
