Like the dirty dozen of produce, there is a list of the top cleanest produce you can purchase that is not organic. These are least likely to contain pesticide residue.
Here's the Cleanest:
When organic is not available, here's some tips to protect you from "non-organic" produce:
Buy fresh vegetables and fruits in season.
Trim tops and the very outer portions of celery, lettuce, cabbages, and other leafy vegetables that may contain the bulk of pesticide residues.
Peel and cook when appropriate, even though some nutrients and fiber are lost in the process.
Eat a wide variety of fruits and vegetables. This would limit exposure to any one type of pesticide residue.
Wait until just before preparation to wash or immerse your produce in clean water. When appropriate, scrub with a brush.
Special soaps or washes are not needed and could be harmful to you, depending on their ingredients. Read the label!
