        1. Let's start with a simple fact: GLYPHOSATE IS NOT A CARCINOGEN

        If you want to be accurate, it is a "probable carcinogen" Even this classification is disputed, but it is factually inaccurate to say that glyphosate is a "controversial carcinogen" in the headline

        This is a vitally important point. There is NO EVIDENCE that glyphosate causes cancer in people who eat fruit/vegetables grown using glyphosate

        There is evidence from animal models that high doses of glyphosate over long periods of time - what you would see in farmers handling the stuff every day for decades - MAY cause cancer

        I cannot stress this enough. Animal models are great, but there is limited applicability when it comes to actual people

        Studies in actual people have not shown a link between glyphosate and cancer. The largest study ever done on the subject, which followed 55,000 people for over a decade, found no link whatsoeverpic.twitter.com/kAPFuNMgXn

        There *may* be a small increase in risk for people who are exposed to enormous amounts for decades (like farmers), but that is a) not demonstrable and b) not applicable to most people

        I mean, honestly, this is a no-brainer. Convincing a jury in California does not mean much in terms of 'truth'

        There is a lot of utility for epidemiologists/public health in determining which products definitely do and do not cause cancer, but for your average person the IARC classification of "probable carcinogen" for glyphosate is worthless

        Glyphosate being a "probable carcinogen" simply means that animal models have shown some association, but human studies have not Which is exactly the point

        Moreover, "probable carcinogen" does not give you any idea of the magnitude of the risk. To see the doses that they use in animal trials, you'd have to drink the stuff for years

        6. EVEN THE ANIMAL STUDIES THAT SHOW GLYPHOSATE IS CARCINOGENIC DON'T ACTUALLY SHOW THAT AT ALL

        There have been a number of animal studies into glyphosate over the years. Thus far, the evidence has been spotty and very inconclusive The IARC decision, for example, was based on only a handful of positive studies

        Of the dozen or so animal studies into glyphosate, about half have shown no association, and a further quarter have shown only a very weak association Not exactly damning

        So, to recap: 1. Glyphosate is not a carcinogen 2. It is a "probable carcinogen" 3. But only at industrial exposures 4. This evidence is weak and spotty in animals 5. And non-existent in humans 6. GLYPHOSATE ALMOST CERTAINLY DOES NOT CAUSE CANCER /end thread
