Schools, restaurants and anyone else serving food are more vulnerable to legal threats over food sensitivities after the Justice Department determined that severe food allergies can be classified as disabilities under federal law. People who suffer from celiac disease don't absorb nutrients well and can get sick from the gluten found in wheat, rye and barley. Celiac is a diagnosed illness that is more severe than gluten sensitivity, which some people self-diagnose. Millions of people are buying gluten free foods because they say they make them feel better, even if they don’t have a wheat allergy. (AP Photo/M.L. Johnson, File)
