While the variety of foods people can be allergic to is vast, some food allergies are more common than others across the globe. In this video, Allergist Dr. Katie Marks-Cogan outlines the eight food groups that make up 90% of all food allergies, and gives an insight into which other foods might soon be added to this list.
While about 160 foods have been reported to cause a food allergy, there are eight main food groups that make up 90% of all food allergies. The eight most common food allergens are milk, egg, peanuts, tree nuts, wheat, soy, fish, and shellfish. The FDA requires that any food that contains one of these eight allergens must be labeled as such. Sesame is actually the ninth most common and will likely be added to this list soon since it's becoming more prevalent.
