How can that be relevant? I mean, this is just the grossest of correlations "Americans have X, and are also exposed to Y, therefore Y causes X"? If anything, it means actually establishing a causal relationship (assuming one existed) would be difficult because the background rate of this disease is so high.

I was responding to the parent commenter’s claim that “gluten intolerance” (quotes theirs) was a “strong warning sign of woo”.

We know that environmental factors contribute to the development of celiac disease, so we should understand the degree to which glyphosate may be one of those.

It's a strong sign of woo because it's very trendy and brought up for all sorts of environmental effects with little actual evidence. Most of those claims must be false.

It’s also true that 12% of Americans are left handed. But that doesn’t mean it’s caused by Roundup.
