Gluten Free Diet

Avoid Cross-Contamination.  Depending on your gluten sensitivity small traces of gluten might not bother you while an extreme celiac can have a single bread crumb cripple them for a week.  Be smart! consult your doctor and speak with a dietitian.  Some of your favorite foods like ice-cream and ketchup can have traces.  Gluten is used heavily in the food industry as a thickener. So when you go out for a nice dinner with your family or friends ask the waiter to consult the chef about any thickeners that may have gluten.
