The Clean Fifteen
To quote from Tim Ferris’ amazing book, The Four-Hour Chef, to eat from this list, if the produce is conventionally grown, will cut your pesticide intake by 90%. His book quotes the 2012 list. I have the updated list for 2013 below.
5. Sweet corn
14. Sweetpeas – frozen
15. Sweet potatoes
