food allergies are autoimmune responses to which specific type of nutrient
Food allergy Common foods involved include cow's milk, peanuts, eggs, shellfish, fish, tree nuts, soy, wheat, rice, and fruit.[1][2][4] The common allergies vary depending on the country.[1] Risk factors include a family history of allergies, vitamin D deficiency, obesity, and high levels of cleanliness.[1][2] Allergies occur when immunoglobulin E (IgE), part of the body's immune system, binds to food molecules.[1] A protein in the food is usually the problem.[2] This triggers the release of inflammatory chemicals such as histamine.[1] Diagnosis is usually based on a medical history, elimination diet, skin prick test, blood tests for food-specific IgE antibodies, or oral food challenge.[1][2]
