How often can i eat gluten if i have celiac disease?

Never: It would likely be in your best interest to never eat gluten at all. If you have celiac disease, even a tiny amount of gluten can do harm to you. Once your gut is damaged by gluten, healing can take 6 months or more. Casein, the protein in milk, looks similar to the gluten molecule, and cross reactivity can happen. Some people also do best being casein free.

Never: If you want to control the disease you can never have it. Sorry, might be tough but can be done. Make it a habit and you won't even remember missing anything.

Things to ponder: Celiac disease is a quirk of your immune system. Every time you eat gluten, your body makes antibodies to the gluten proteins as if they were germs, those new antibodies attack your gut tissues & maybe some other tissues like your brain, skin, etc. Those antibodies hang around for months to years & you generate new ones every time you eat gluten. This is not a simple allergy that clears.
