Their "organic food score" was based on the responses to whether people ate 16 types of organic food There is a significant issue with bias herepic.twitter.com/hobNrXKgDh

Thirdly, the absolute risk is tiny The "high organic" group ate MORE THAN 20x the organics of the "low organic" group, and they only saw a 0.6% reduction in risk That's a huge expenditure for a minuscule benefit, even if this study is correct
Finally, there's a good chance that these results are meaningless. The more factors the authors controlled for, the smaller the statistical difference There's a good chance that if you could control for everything, the result would disappear entirely
This study probably means very little to your life. Eating organic is ~probably~ better for the environment, but that's about it I've written about this beforehttps://medium.com/@gidmk/organic-food-isnt-better-for-your-health-93a35584639d …
Also, this isn't a criticism of the study, the actual research was pretty cool. I would say that the authors were a bit optimistic in their conclusion, but otherwise it was interesting epidemiological researchpic.twitter.com/LxIlXpe98s
Something I missed earlier - it's also worth noting that in most of the interesting subgroups the association totally disappearedpic.twitter.com/Iv2pvCDg2u
What this means is that organics are likely only useful in reducing the cancer risk of elderly women, which to me points to the results being likely down to statistical noise
If the effect disappears when you don't look at a single group of cancers - postmenopausal breast cancer - then it's more than likely it's not there at all
Also worth noting that the results are probably not generalizable, considering that this sample was heavily weighted towards highly-educated French women
Would be interesting if the study had looked at pesticides (including looking at different types - where's glyphosate in all this?), as well as other conditions and chronic diseases.
There are plenty of studies on each individual pesticide though, and dietary intake is virtually impossible to calculate based on questionnaires
