Buy organic whenever possible. If you can’t afford or find organic foods, no problem. Just wash your fruits and vegetables very well. Go to foodnews.org and find out which produce contains the most pesticides and make yourself an organic produce priority list. Only buy organic of those in the dirty dozen (peaches top this list) and accept conventional of those in the cleanest dozen, such as onions. If you can’t get fresh produce, frozen is the next best thing. Avoid canned and packaged fruits and vegetables as the preservatives are usually going to work against you.
