Posted this above, but will repost here because it's relevant.

There are numerous studies that show glyphosate binds with aluminum and other metals, having negative impacts on public health.

Anything that reaches the gut intact disrupts (ie: manipulates, interacts with, alters, stimulates or suppresses, selects) the gut biome. I'm not pushing back on you except to say that as a mechanistic axiomatic claim of harm, it's missing most of the evidence. You could be right, but you could also be wrong; what you've said so far can't possibly be dispositive.

Roundup also contains a very strong surfactant and we know that those totally fuck up your GI as well.

AFAIK the preponderance of the evidence is that most "gluten sensitivity" is actually just a FODMAP sensitivity, which also interacts with the gut biome.

I will never understand this bizarre obsession with gut flora. We don't know what is normal, what is a beneficial ratio or when a change happens if that is good or bad thing. No one besides the people who study these things should be much attention to gut microbiomes. We just don't have enough information to let this be an influence on decision making.

Changing your diet disrupts the gut biome. When I started eating bran flakes it massively disrupted my gut biome. Should I be alarmed? Or are you slipping a double standard in there, perhaps from the naturalistic fallacy?

People who have gluten allergies have a legitimate disease, typically celiac disease.

Being tired after eating bread or whatever is not a gluten allergy, that's just how food works. A lot of people claim to have gluten allergies but no, you would know for sure if you had a gluten allergy.
