This has now been studies and proven link between the two but we know where it might be coming from into our food supply Dr.Seneff glyphosate on wheat. They spray glyphosate [roundup] on wheat crops so they can get a more uniformed harvest. Here is his paper in the US National Institute of Health https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3945755/ and more information https://people.csail.mit.edu/seneff/
I eat pretty gluten free not because I have celiac or any allergies but it just turns out that way because I eat low carb mostly. So, I'm not too worried, worry more about other things I should or shouldn't have done. I wish I never smoked and although I quit 9 years ago...I'm sure the damage is done. My mom died last year from complications of emphysema She was a smoker but also quit when she was around 39-40. She would still be alive in my opinion. Had no other health problems.
Far worse than Glyphosate is 2,4,-D, an herbicide even more widely dispersed globally than Glyphosate, and much longer-lived in the environment. See https://en.wikipedia.org/wiki/2,4-Dichlorophenoxyacetic_acid Frank
