buying organic (and local!) produce is extremely important to me. sometimes though, my wallet just won't allow for it. knowing which items are most and least important to purchase organic has been a tremendous help to me (and our bank account!), so i thought you might be able to use the info as well. here's a simple guide to what you should always buy organic, and what other items are naturally low in pesticides (usually due to their thick skins).
THE WORST for pesticides (buy these organic):
spinach, peaches, strawberries, apples, blueberries, kale/collard greens, potatoes, bell peppers, celery and grapes.
always try to buy these organic, as their thinner skins allow for the most amount of pesticides to reside within.
THE BEST (lowest in pesticides):
onions, sweet corn, sweet peas, asparagus, cabbage, eggplant, pineapple, sweet potato, melons and avocado.
when you're in a money pinch, you can always rest assure that these veggies and fruits have the lowest amount of pesticides.
