Toxic Fruit Salad

The problem: Nonorganic fruits can harbor up to 64 different pesticide residues. Summer staples like nectarines, peaches, grapes, and blueberries have some of the highest levels, according to the Environmental Working Group's most recent Shopper's Guide to Pesticides in Produce.

The fix: Even with the pesticides, nonorganic fruit salad is still healthier than the other mayo-laden sides most people tote to picnics. But use as much organic fruit as possible to lower your exposure to pesticides linked to nerve damage, hormone disruption, and other reproductive problems.
