Take a look at the list below which is labeled the dirty dozen and the clean 15. The dirty dozen are those fruits and vegetables with the highest pesticide loads. The clean 15 are the fruits and vegetables with the lease pesticide residue.

The EWG (Environmental Working Group) has performed in-depth studies to determine what fruits and vegetables have the most pesticides and herbicides and what ones have the least.  

Keep in mind that transformation is a continual process of letting go of what does not serve you and adding food and habits that will benefit you.
