What Should You Buy Organic?

Of the 43 different fruit and vegetable categories tested, these 12 fruits and vegetables had the highest pesticide load, making them the most important to buy or grow organic:

Peaches

Apples

Sweet bell peppers

Celery

Nectarines

Strawberries

Cherries

Lettuce

Grapes (imported)

Pears

Spinach

Potatoes

Strawberries were found to be highly toxic due to a poisonous blend of pesticides in a previous 2007 EU study as well. But be VERY careful as the list above is for fruits and vegetables. Non-organic meats have higher concentrations of pesticides than all of the fruits and vegetables. The highest concentration of pesticides is in non-organic butter. So if you can only buy one organic food item it should be butter. Next priority would be meats and once those are addressed, you will want to focus on the fruit and vegetable list above.
