(ABCNEWS.GO) — Tyler Trovato loves his peanut butter and jelly sandwiches with a glass of milk, but if he diverges from that and only a handful of other foods, the 6-year-old goes into a fit of vomiting and lethargy so severe that he has to go to the emergency room.

The St. James, N.Y., first-grader is allergic to just about everything else — chicken, turkey, rice, sweet potatoes and bananas, among others. As an infant, he was even allergic to his mother’s breast milk and she was a vegetarian.

Since he was 18 months old he has to be hospitalized before he can try a new food.
