When to Buy Organic
Article first published as Another Reason to Go Organic on Technorati.
The market for organic foods has been growing rapidly. Growing concern about the effects of synthetic pesticides on the environment and health have resulted in 20% annual growth in retail sales of organic foods since 1990 (according to the USDA).
Given that these products typically cost more than the non-organic version and are less available, how do you know which foods are safe and which should be purchased organic?

The Environmental Working Group (EWG) recently released its Shopper’s Guide to Pesticides in Produce - which includes a "Dirty Dozen" list of the fruits and vegetables that are more likely to be contaminated with pesticides as well as a "Clean 15" list of the fruits and vegetables least likely to be contaminated.
EWG recommends buying organic for the "Dirty Dozen":
Apples
Celery
Strawberries
Peaches
Spinach
Nectarines (imported)
Grapes (imported)
Sweet bell peppers
Potatoes
Blueberries (domestic)
Lettuce
Kale/collard greens
The "Clean 15" are:
Onions
Sweet corn
Pineapple
Avocado
Asparagus
Sweet peas
Mangos
Eggplant
Cantaloupe (domestic)
Kiwi
Cabbage
Watermelon
Sweet potatoes
Grapefruit
Mushrooms
The EWG reports that by opting for 5 servings of fruits or vegetables off of the "Clean 15" list instead of the "Dirty Dozen" list can reduce the volume of pesticides ingested by 92%.
Pesticides have been linked to numerous health issues, including birth defects, nerve damage, cancer, and even more for children according to the Environmental Protection Agency. Experts have even linked pesticide consumption in children to ADHD.
