A 12-year-old boy from the U.K. is allergic to so many foods that he must exist on a diet of chicken, carrots, grapes, potatoes and apples, according to a report in London's Evening Standard.
Tyler Savage, of Earls Colne in Essex, becomes violently ill every time he eats food containing dairy products or wheat, gluten, eggs, lactose and soy.
Tyler was first diagnosed with a rare condition at age 6 when even a morsel of food would cause him sickness and diarrhea. At first though, doctors were stumped, the boy's mother said.
Lynne Savage, 43, said the family was initially told her son was suffering from a stomach infection. Doctors later suspected his appendix, which was removed in December 2005, but failed to fix the problem.
Finally, in April of this year, Tyler was diagnosed with eosinophilic enteropathy, a rare condition in which the intestines produce too many white blood cells. The boy must be fed through a tube in his stomach.
