Food allergies are one of those problems that affect many people in the community, and sometimes require medical attention. In fact, they affect around 5% of adults and 8% of children – and that number is rising. While any food can cause an allergic reaction, statistics show that some foods are more likely to cause an allergic reaction than others.

Any food can cause an allergy. However, only a few foods cause at least 90% of allergic reactions to food. The substance that causes an allergic reaction in a food or drink is called an “allergen”. In terms of food, almost all allergens are proteins. For most people, these proteins are not allergens, because their immune system does not react to them. It is the immune system’s reaction to these proteins that causes an allergic reaction. In this article, we will provide useful information to help you better understand the most common foods that are likely to cause allergies.
