Explain the difference between a food allergy and a food intolerance. Give examples of each
What will be an ideal response?
Answer: A food allergy is an immune hypersensitivity—an overreaction by the immune system—to a protein in a food. It can produce discomfort such as a rash or abdominal cramps, or more serious symptoms, such as impaired breathing or even life-threatening, body-wide inflammation and cardiovascular problems known as anaphylaxis. Common food allergens are milk, peanuts, eggs, wheat, soy, tree nuts, fish, and shellfish.
Food intolerance is not due to an immune hypersensitivity. Rather, it reflects the body's inability to digest some component of a food. Although it may produce physical symptoms such as bloating, abdominal cramps, and diarrhea, they tend to be temporary and resolve as soon as the food has passed through the gastrointestinal tract. The most common food intolerance is to the lactose disaccharide in milk. Many people believe that they have an intolerance to gluten, a protein found in wheat, rye, and barley. Gluten intolerance is not the same as celiac disease, which is a serious autoimmune disorder in which an affected person's immune system produces an inflammatory response in the small intestine whenever the person consumes gluten. The immune response degrades the lining of the small intestine, reducing nutrient absorption, and leading to weight loss, pain, and other signs and symptoms.
