Food allergies are quite common these days. At some point of time, you or some of your dear ones would have come across this issue.
What Are Food Allergies And What Causes Them?
When your body's immune system reacts unsuitably when certain food products are consumed, it could result in an allergy. Most of the time, it is one or more substances in the food that actually makes your body response to its intake in an inappropriate manner.
When a food is treated as harmful by the body's immune system, the body begins to create immunoglobulin E antibodies against it. So, every time you eat this particular food, even in the slightest amount, the body's immune system begins to release this chemical to fight it. Creation of these chemicals is what actually results in the signs and symptoms of an allergy.
According to the data provided by the FDA (U.S. Food and Drug Administration), there are specifically eight different types of foods that are responsible for causing about 90 percent of the allergies. Food manufacturers are required to mention in plain words if the packaged food products that they sell contain any of the mentioned eight varieties of substances. As per the Food Allergen Labeling and Consumer Protection Act of 2004, these eight types of food items are eggs, peanuts, milk, soy, fish, wheat, tree nuts and shellfish.
Are You At A Risk For An Allergy Due To A Particular Food?
The following are some of the factors that can increase the chances of you having a food allergy:
• Going by what the Mayo Clinic has to say, toddlers and infants are the ones who are highly prone to food allergies. If your kid shows allergic signs when they consume milk, eggs, wheat or soy, you can be sure that it might reduce over time. However, allergic reactions towards nuts and shellfish last longer.
• If members of your family have hay fever, eczema or asthma, then the chances of you having a food allergy are high.
• If you possess a food allergy or are already allergic to a few substances, then you are at a higher risk of attracting other food allergies as well.
• Most of the time, it has been seen that eczema, asthma and food allergies coexist. Symptoms of a food allergy can get worse if you already suffer from asthma.
• If you have a history of food allergy, that is if you were allergic to a particular food at a young age, you are highly likely to suffer from it at a later stage of your life as well.
