If #2, can you please supply these studies in the comments. I do realize there is a difference between thick-skinned and thin-skinned produce and the use of systemic vs. non-systemic pesticides nor do I wish to belittle your harm-reduction or avoidance strategies, I'm just curious.
Because the pesticides, preservatives, etc. might have a harmful effect, and while organic is often more expensive, it's not prohibitively more expensive. So it's more of a "playing it safe" kind of thing rather than a "scientifically proven" kind of thing for me. Also, I like buying local when possible, at the farmer's market, and more of that tends to be organic.
Cause I saw an ape throwing the banana shell of a conventional banana away while eating an organic one without even peeling it.
I have found that it tends to taste better, especially with regard to fruits and vegetables. Organic pears remind me of the pears I used to get at a local, organic-in-practice-not-name (before certification was common, but it was owned by hippie-types) orchard when I was a child; I have never found a conventionally grown pear that tasted quite as good.
There is also the pesticide issue...it skeeves me out, and it seems that if I can afford to buy plants not coated in those chemicals and cut down on potential risk, why wouldn't I? There is no real downside if you can afford it. Plus, I like to wander farmers' markets and support local farms. It makes for a good Saturday morning with the husband.
I also raise my own organic fruits and veg. It's not very difficult, and I'm squicked out by the idea of spraying conventional pesticides on my "babies." They do great without.
I buy organic roots (carrots, parsnips, potatos) because they always taste better. The rest I buy local and wash well before eating/cooking. Sometimes it's organic, sometimes not. In switzerland the regulations for what passes as "organic" are stricter than in the US, and also just in general stricter for conventionally grown produce, so I don't stress too much about it. If your motive is the environment then it's way more sustainable to buy local fresh than organic transported from South America or whatever.
