We all know that it is best to avoid pesticides, but it is not always possible. Fortunately, there are some commercially grown fruits and veggies that tend to have lower amounts of chemicals adhering to their surface. The more you consume from the "Clean" list, and the fewer you consume from the "Dirty" list, the lower your toxic load will be. Here are the lists:
DIRTY DOZEN - buy these organic:
celery, peaches, strawberries, apples, blueberries, nectarines, bell peppers, spinach, kale, cherries, potatoes, imported grapes
CLEAN 15 - lowest in pesticides:
onions, avocadoes, sweet corn, pineapple, mangos, sweet peas, asparagus, kiwi, cabbage, dggplant, cantaloupe, watermelon, grapefruit, sweet potato, honeydew melon.
It's best to buy organic, pesticide, sustainable agriculture, or biodynamic whenever possible. But, it's also good to know what the best choices are when those aren't available.
