One of my biggest hurdles is that I cant always afford to buy organic. I dont buy organic just to protect the earth I do it mostly because I do not want to subject my family to pesticides and preservatives. Here is some information about the dirty dozen from Sara Snow. If you cant afford to buy all your produce organic at least try to buy these:
There have been a couple of studies done on fruits and vegetables to determine which are the cleanest (without pesticide and chemical residues) and which fall the other way. The Environmental Working Group did one such study and it resulted in a list they call the Dirty Dozen. It makes sense to buy organic for the items that fall into their dirty category; and that you might be able to save some money by sticking with conventional varieties of their cleanest twelve. According to the EWG list the following fruits and vegetables are the dirtiest twelve: peaches, apples, sweet bell peppers, celery, nectarines, strawberries, cherries, pears, imported grapes, spinach, lettuce and potatoes. On the other hand, onions, avocado, frozen sweet corn, pineapples, mango, asparagus, frozen sweet peas, kiwi, bananas, cabbage, broccoli and papaya are the cleanest.
