The EWG (environmental working group) cleverly calls the 12 fruits and vegetables listed below the "dirty dozen" due to their high levels of pesticides, when compared to other produce. If possible, purchase the following organic produce.

1. Apples
2. Celery
3. Strawberries
4. Peaches
5. Spinach
6. Nectarines
7. Grapes
8. Sweet bell peppers
9. Potatoes
10. Blueberries
11. Lettuce
12. Kale/collard greens

The clean 15

This next group of 15 produce are known by the EWG as the "clean 15". They are the lowest in toxic pesticides, so if you're going to buy non-organic produce, these would be the ones to buy.

1. Onions
2. Sweet corn
3. Pineapples
4. Avocado
5. Asparagus
6. Sweet peas
7. Mangoes
8. Eggplant
9. Cantaloupe
10. Kiwi
11. Cabbage
12. Watermelon
13. Sweet potatoes
14. Grapefruit
15. Mushrooms

Consuming foods from the clean 15 will lower your pesticide exposure a whopping 92% when compared with the dirty dozen. By choosing five fruits and vegetables a day from the clean 15 list you'll consume fewer than two pesticides per day, whereas consuming five fruits and vegetables a day from the dirty dozen will cause you to ingest as many as 14 different pesticides every day.
