A friend asked me to do some research on the topic of when it most matters to purchase organic fruits and vegetables. The article below is the end result.It is often difficult to justify the extra money for organic produce. When you are standing in the market in front of the strawberries, both organic and non-organic varieties look the same and often smell the same (to our industrialized nostrils). There are certain fruits and vegetables which take larger pesticide hits when grown conventionally.
If given a choice, always spend the extra money to purchase organic on the following items which have the highest levels of pesticides (according to the EWG):
Strawberries
Apples
Peaches
Spinach
Nectarines
Celery
Cherries
Potatoes
Pears
Sweet Bell Peppers
Imported Grapes
Raspberries
The least pesticide contaminated foods, grown conventionally, are:
Sweet Corn
Pineapples
Cauliflower
Mangoes
Avocados
Sweet Peas
Asparagus
Broccoli
Bananas
Onions
Papayas
Kiwis
One of the reasons organic costs more is that its processes are more time-consuming. Organic farming employs the labor-intensive techniques of crop rotation and crop covering (planting coverage plants between the rows), and the use of manure and compost as fertilizer.
According to the EWG, Americans can lower their pesticide exposure by 90 percent by avoiding the 12 most contaminated fruits and vegetables.
A great way to find organics in your area is through CSA (Community Supported Agriculture). Visit the CSA web site -
http://www.csacenter.org/ - and located CSA's in your area of the country.
Another good source is your local farmer's market. Not all produce offered at farmer's markets is organically grown, but a great deal is. To locate one near you:
