Polly,
I should have seen that one coming.
As you are well aware, I'd love to see more substantial scientific/medical proof, but I have to agree with you that the stuff has become absolutely ubiquitous and that's worrisome.
I'm not Monsanto's biggest fan by any means, but if anyone is out to make a case against the product that is meaningful, I don't understand why researchers can't find a more substantial clue than a change in an enzyme produced by a species of gut bacteria. Statistically, it would probably be impossible to find any chemical in existence that does not cause an enzyme change of some type in some species of gut bacteria. But so what? That's really not substantial evidence of anything incriminating. It's just evidence that it's possible to find physiological changes in bacterial species exposed to various chemicals (in vivo or not). I would truly love to see some real evidence of something substantial before many more generations go by. Roundup has been on the market for over 42 years now. How much time do researchers need? Surely Monsanto doesn't have the market cornered on qualified researchers.
As for the WHO, they see the cause of cancer everywhere they look.
First they blame meat. They blame glyphosate. And I notice on their latest blog, they even blame ageing as "a fundamental factor for the development of cancer".
So I reckon we old codgers bring it on ourselves by the mere act of becoming old codgers.
Seriously though, when colon cancer rates are increasing in younger people, it's pretty obvious that something may be going terribly wrong with our food production and/or processing industry. And I'm not just talking about the domestic industry — I'm talking about world-wide food trade. I believe that another overlooked issue here is the fact that the timing of this trend correlates with a huge expansion in world trade. When I was a kid, probably 90 to 95 % of the food I ate was locally sourced, and the rest came from other areas of this country. My gut biome had no trouble recognizing any of the food that passed through my gut because for many, many generations it had evolved with it.
When we chow down these days, there's no telling where most of the food we are consuming actually originated. We have no idea where or how it was produced and processed. We don't even know who inspected and approved it for import. But the big issue here is that our gut biome most definitely does not match the gut biome of any of the indigenous people of any of those countries.
And that's another serious concern, IMO.
Remember all the old jokes about Montezuma's revenge for anyone who traveled from the U. S. to Mexico? There's a reason why that happened — gut biome mismatch.
