Top 10 Types of Food Allergies

Article by ,

Food, when on one hand is very essential for our body, on the other hand can become a grave problem. There are hundreds of foods out there which your body is sensitive to. We call this “Food allergy”. A person at times, after a particular ingredient, shows abnormal reactions like rashes, swelling, itchiness, sores etc. This is nothing but an immunogenic response given by your body. It happens when, the body’s self-defense system, is overly active and it starts considering a particular food element as a foreign particle. The antibodies which are produced in this battle are the reason behind those allergic symptoms. It is hard to predict as to which food can sensitize you. It is only after the symptoms, that you know that you are allergic. The list of foods that can give rise to allergic reactions is pretty long. But there are a few elements which are responsible for almost 80% of  Food Allergy cases. Depending on this, the following are the top 10 types of food allergies.

10. Sesame allergy


In the recent times, the number of patients reporting sesame allergy has increased markedly. It is because sesame has now gained a wide acceptance throughout the globe. Sesame is used for its exotic flavor. It is used to garnish various cuisines. Sesame oil is also widely used in salads and continental foods. Sesame allergy can be very serious if untreated as it can give rise to an anaphylactic shock as well. Allergic people should avoid the use of the seeds as well the compressed oil of the seeds.

9. Celiac disease or gluten intolerance


Gluten is a constituent of a wide variety of foodstuffs. It is largely found in cereals like barley, oats, rye etc. It is basically a mixture of several proteins. This is actually a chronic disease and eventually the stomach lining degrades completely. Due to this the body is not able to absorb nutrients and consequently becomes malnourished. It has been estimated that 1 out of every 300 people in US and UK suffer from celiac disease. The only way to treat this is to avoid gluten containing edibles. There is no other cure for this.

8. Soy allergy


Soy is one of the most common allergens in US. It has been seen that it affects children more. Soy allergy is rarely found in adults. Around 0.4% children in America report soy allergy and 50% of these grow out of it by the time they reach 7 years of age. Soy is a very widely used in packaged foods. Breakfast cereals, ice creams, drinks, processed meat etc. all contain soy. The symptoms include, stomach cramps, vomiting, diarrhea and breathing problems.

7. Wheat allergy


This is another type of allergy which largely affects the children. About 0.4% children in America alone suffer from this. But most of them, almost 80%, grow out of it by the time they are 6 years of age. Wheat contains a constituent which is called gliadin. This is thought to be the reason for causing allergies. This gliadin is also found in gluten. This is the reason that people who are allergic to wheat are asked to avoid gluten containing edibles as well. People having wheat allergy should also avoid beer, Kamet, crab meat as they contain similar proteins to wheat.

 6. Fish allergy


Another common type of allergy is “fish allergy”. It has been reported that around 0.4% of adults and 0.1% of children in USA suffer from fish allergy.

It may happen that the child is allergic to just the egg white or just the egg yolk or to both. The problematic constituents in the egg are ovalbumin, ovomucoid, and conalbumin. Some of these can be destroyed by cooking but some still remain. Some children might react to cooked eggs as well. People allergic to turkey, chicken might also show egg allergy.
