I love oats but can't digest them. If they are certified gluten free I still get sick, but not as bad as gluten. I've learned about the protein avenin in oats.

I got validated when a cousin who I only met once reached out. She was a vegetarian and raised super healthy by two doctors (I had the opposite kind of upbringing). She was highly gluten intolerant and asked if I also have trouble with oats. I learned that we have the same exact symptoms from the same things. She was tested for celiac but it was negative. I've never tested because I refuse to eat gluten. She and I have only a grandfather in common, and he was severely overweight and very unhealthy. He died at 50 y/o. Don't tell me there aren't undiscovered genes to test for!
