Food Allergies - Reasons, Symptoms, Precautions, and Treatment
Many people are fond of eating but some are compelled to avoid some of the foods. Because they have allergies to some of the foods and drinks. The number of such people in recent years has increased. They think they have allergies to some of the foods and drinks or their stomachs can't bear them. But it has been revealed in research that in fact, only a few people have allergies.
Why allergy to some of the food?
A report has been published in one of the medical magazines of America in which it has been told that the experts have different opinions about allergies to foods and drinks. But most of them have consenses allergies begin due to the immunity system. Allergies from foods or drinks are due to proteins present in them. The immunity system understands that this protein is harmful to the body. So, when this protein enters a body, the immunity system of the body makes an antibody (a kind of protein) which is called Immunoglobulin E.
This antibody fights against the protein that enters the body. When a person eats the food again that contains the said protein, then this antibody makes some chemicals that contain a chemical called Histamine. Normally Histamine plays a very useful role in the immunity system. Therefore, the experts are unable to understand how Immunoglobulin E and the making of Histamine become the reason for revealing the symptoms of allergy. This information shows that eating the food for the first time may not cause an allergy but eating the same food again causes an allergy.
Why stomach can't digest some of the foods?
As some people have allergies to some of the foods and drinks, just like some people's stomachs can't tolerate some of the foods and drinks. This problem belongs to the digestive system, not the immunity system. Therefore, no antibodies are made. In fact, the deficiency of an enzyme (a chemical substance) may be the reason, or then the presence of some of the specific chemical substances in the food can't be easily absorbed in the stomach. For instance, some people can't digest the sugar present in the milk because their stomachs don't produce the enzymes that are necessary to digest the sugar present in the milk and its products.

Allergy can occur to a person of any age. It has been revealed in research that if parents have an allergy to any food or drink, the allergy can be found in children from the same food or drink also. But it has been also noticed when a lot of children grew up, they don't have an allergy to that food or drink. When the stomach can't digest anything, its symptoms are less dangerous as compared to that of allergy. The following can be the symptoms of it:-

Treatment
If you think that you have an allergy to a food or drink or your stomach is unable to bear it, consult any expert doctor. If you avoid some of the food without consultation with a doctor, it can be harmful to you. Because your stomach will not get some of the important vitamins and proteins.
For people who have severe allergies to some foods or drinks, there is no special treatment available for them except to utterly avoid those foods and drinks that caused allergies to them. But the people who don't have a severe allergy or their stomachs can digest a small amount of food, they can eat a slight quantity of that food. In some situations, a person has to completely avoid the food that his stomach can digest.
