People with food allergies have an allergic reaction* when they come in contact with certain foods. This happens because their immune system overreacts to the proteins in that food. Eight kinds of food cause most food allergies: 1) Cow Milk, 2) Eggs, 3) Peanuts, 4) Wheat , 5) Soy, 6) Fish, 7) Shellfish, 8) Tree nuts.
Signs of a food allergy include:
• A rash, or red, itchy skin
• Stuffy or itchy nose, sneezing, or itchy and teary eyes
• Vomiting, stomach cramps or diarrhea
• Angioedema or swelling
• Hoarseness, throat tightness or a lump in the throat
• Wheezing, chest tightness or trouble breathing
Some people with food allergies can have a serious reaction called anaphylaxis*. It is common for people and even some healthcare providers to misdiagnose the difference between food allergy and food intolerance. Food allergy can result in a life-threatening allergic reaction. On the other hand, a misdiagnosis could mean that you are unnecessarily limiting what you eat.
