Wheat allergies are induced by exposure to wheat proteins such as albumin, gliadin, globulin, and gluten. This can result in itching, intestinal discomfort, and respiratory concerns (17). Although rare, some people may have a reaction to the flour itself. The whole grain contains several different starch molecules that may cause issues for some individuals. Those who suffer from wheat allergies should avoid products that contain wheat flour as well as products that have been processed with wheat flour. You should also exercise caution when eating out at restaurants because many foods are prepared with wheat flour. It is important to know what ingredients they use to ensure that you do not have an adverse reaction to any of them. If you're concerned that you might have a problem with wheat, talk to your doctor about alternatives before you start avoiding food groups. He or she will be able to help determine if there are any specific foods that should be avoided so that you can maintain good health.
