Survey data suggest at least 1 in 10 U.S. adults are food allergic and nearly 1 in 5 believe they have a food allergy. Food allergies are expensive and potentially life-threatening conditions.
In this nationally representative survey study of more than 40,000 U.S. adults, nearly half of food-allergic adults developed allergies during adulthood, many reported being allergic to multiple foods, and 38 percent reported at least one food allergy-related emergency department visit in their lifetime. Shellfish allergy was the most common, followed by milk, peanut, tree nut and fin fish. Self-reported food allergies by study participants weren't confirmed by diagnosis.
