Although any food can potentially trigger an allergy, 90% of the life-threatening reactions are caused by eight foods: peanuts, eggs, milk, wheat, tree nuts, soy, fish and shellfish. Cow's milk, eggs, wheat and soy are the most common sources of food allergies in children. An early peanut allergy may last a lifetime.
Take action: In highly allergic people even minute amounts of a food allergen – 1/44,000 of a peanut kernel, for instance – can prompt an allergic reaction. Read labels carefully to determine if packaged foods have been produced in a factory where nuts are processed. Avoid the product at all costs.
