Welcome to the forum, @RDB7918393! For some folks, gluten reactions are delayed but I would not think symptoms delayed  of a week or more out would be due to a gluten reaction. Twenty four hours or so but not 7-14 days. I would suspect something else is going on. Eating out is well-known to be the number one sabotaging activity of the gluten-free life style. 

I was diagnosed with Celiac about 10 months ago after having on and off morning stomach cramping and loose stool that only occurred like once a month. So I don’t get immediate reactions…more if build up reactions. I do my best to be gluten free but hard when on vacation and going to restaurants to fully trust cross contamination problems. I find that if I’m cross contaminated, I don’t get a reaction til about a week or two after. The reaction is stomach cramping morning only with flaky stool. Does anyone else have such a delayed reaction like a week or two after being glutened? Or should I go for more testing to see what’s going on.

Good morning, I saw that a lot of people were asking wether Polly-O products are gluten free. I just called them and all their cheeses are gluten free! Just wanted to let anyone know.    if you still want you can give them a call.

Thank you very much Scott I am glad that there is a light at the end of this tunnel. I am just very impatient and I want to heal asap.

But, I am so grateful that I found a site like your that can help me and put my mind at ease in all of this. An you started this and you are ghelping alot of us get through this little by little. I thank you for starting this. Is there a cure coming that you know of? I am in Canada and there is nothing here.   Sophia    

Your approach is spot-on—trusting reliable sources like Mayo Clinic and sticking to a gluten-free diet that works for you is the best way to navigate all the noise out there. The claim that rice and corn contain forms of gluten harmful to celiacs is indeed a misconception. While these grains do contain proteins that may technically be referred to as "glutens" in a broader scientific sense, they are structurally and functionally different from the gliadin found in wheat, which is the specific protein harmful to those with celiac disease. Scientific research overwhelmingly supports the safety of non-contaminated rice and corn for celiacs unless there’s a separate sensitivity or allergy involved. Some opinion pieces or alternative health sources may blur the lines by conflating these proteins, which can cause unnecessary worry. You're absolutely correct to focus on the distinction between scientifically validated information and anecdotal claims. It's also important to note that some people with celiac disease may develop sensitivities to other grains over time, but this is individual and not a universal rule. If you’re asymptomatic and thriving on a diet that includes certified gluten-free products with rice and corn, there’s no reason to change what’s clearly working for you. The internet is a breeding ground for well-meaning but misguided advice, and it’s easy to feel overwhelmed. Your instinct to validate claims through reliable research is exactly the right way to go. Keep enjoying your gluten-free meals, stick with trusted certifications, and don’t feel pressured to adopt restrictive diets that aren’t backed by science or tailored to your specific needs. Happy New Year to you too!
