If i have celiac, can i still eat what i want once in awhile>?

Avoid gluten always: With celiac disease, exposure of the intestine to any gluten causes inflammation of affected gut lining, with a decrease in absorptive surface of that gut, & resulting malabsorption of food. The best & most enduring fix is to avoid eating any gluten. Serum tissue transglutaminase antibody can help determine how successfully gluten is avoided. Don't compromise your health for taste preference.

Shouldn't : It is best to follow a strict gluten free diet. But patients vary in their responses to small amounts of gluten.
