“Avoid waxed foods. You can tell if something is waxed by smelling the stem; if it does not smell like the food, then it’s likely waxed. the problem with wax is that it locks in pesticides that can be found on fruits like apples, pears, and nectarines. Other big pesticide offenders include berries, potatoes, peppers, spinach, lettuce, and celery.

Here are the fruits and vegetables with the highest and lowest pesticide contents, if you’re not going to go organic:
Highest: Peaches, apples, bell peppers, celery, nectarines, strawberries, cherries, kale, lettuce, imported grapes.
Lowest: Onions, avocadoes, sweet corn, pineapples, mangoes, asparagus, sweet peas, kiwis, cabbage, eggplants.” -From the authors of the “You” series; Drs. Roizen & Oz
