If you can't afford to buy all-organic fruits and vegetables, buy the ones that really count. Ideally, thin-skinned fruits like strawberries, grapes and apples should always be organic. Berries absorb pesticides and herbicides like sponges. Apples are cultivated with high levels of pesticides, so scrubbing each apple and peeling it is important. And because grapes have been found to be heavily sprayed as well, immerse them in water, using a special soap spray to clean them. You can even peel each grape for safer eating.
