If you didn’t grow up with a food allergy, you’re not off the hook. They can spring up without warning at any time of life.

Food allergy doesn’t rank high on the list of later-life maladies. Only 4% of adults are allergic to a food, and even those who begin life with the most common food allergies — to milk, eggs, wheat, and soy — are likely to outgrow them by the time they enter kindergarten.
