Great post! Especially since so much of produce has been sprayed with pesticides.
Important to at least choose organic, especially for the "dirty dozen" list (in the US) - strawberries, spinach, nectarines, apples, peaches, pears, cherries, grapes, celery, tomatoes, sweet bell peppers, potatoes.
There's also a "Clean 15 List" - produce least likely to be contaminated by pesticides...
- sweet corn, avocados, pineapples, cabbage, onions, frozen sweet peas, papayas, asparagus, mangos, eggplant, honeydew, kiwi, cantaloupe, cauliflower, grapefruit
