Organic food is devinetively not snake oil. As you mentioned,Nutrition wise its exactly the same. However, the Environmental Impact is completely different. Organic farming is much better in terms of biodiversity, soil health. Since organic farming doesn’t include the use of pesticides it doesn’t kills everything else that would live on a field. Also, Theres always parts of the pesticides that stay in the crops and that you eat. I don’t know exactly how bad they are, but considering that(at least in Germany) Parkinson is an accepted work related illness for farmers its sure that they aren’t entirely safe for humans. However, we should take into consideration, that farmers get exposed to much higher doses of pesticides. If someone has some articles regarding this topic feel free to share.
