It is a well-known fact that buying organic fruits and vegetables is the healthiest choice. While this is all good, but the who could afford to spend about 10 euros a kilo for avocados on a regular basis? The best you can do is find out which are the “dirtiest”, according to the well-known “Dirty Dozen” list of the Environmental Working Group and make sure these are at least organic, as not all fruit and vegetables absorb the same amount of pesticides.

2. spinach
3. nectarines
4. apples
5. Peaches
6. Pears
7. Cherries
8. grapes
