Some organics worth buying, experts say

Some say consumers can decrease their risk of pesticide exposure by 80 percent. Other do not believe the chemicals are harmful.

Nonetheless, the Good Housekeeping Institute recommended those buying organic stick to the following produce: peaches, apples, sweet bell peppers, nectarines, strawberries, cherries, grapes, pears and tomatoes, celery, kale, leafy greens and carrots.

Produce with thin skins, like these peaches, don't have the physical barrier to the pesticides that produce with thicker skins have.

The conventional fruits and vegetables shown to have the least amount of pesticide are onions, avocados, pineapple, mango, asparagus, peas, kiwi, eggplant, papaya, watermelon, broccoli and sweet potato.

Some organic produce has a shorter lifespan than conventional produce, so buy less and buy often, experts said.

The type of produce is less important than the amount, the institute's experts said.
