Bananas are not on the Dirty Dozen list although they do contain some pesticides if they are not the organic variety of bananas.
Bananas instead are on the EWG's Clean Fifteen list, that highlights produce that has the lowest pesticide residues, which is due to the thick skin that protects the bananas from the pesticide residues.
The Dirty Dozen is a list of fruits and vegetables that have the highest pesticide residues when they are conventionally grown.
The Dirty Dozen list of fruits and vegetables with the highest pesticide residues is compiled annually by the EWG also called the Environmental Working Group.
The fruits and vegetables on the Dirty Dozen list are items that you should ideally prioritize buying organic to minimize your exposure to pesticides.
Examples of fruits and vegetables that are on the Dirty Dozen list include.
Potatoes, Blueberries, Blackberries, Apples, Pears, Nectarines, Cherries, Peaches, Grapes, mustard greens, collard greens, kale, Spinach and Strawberries.
However these foods still are nutritious and healthy to eat and you can often wash off the pesticide residue from the outside through use of water and some baking soda.
You should still eat these fruits and vegetables but if possible opt for the organic variety although if you cannot get the organic variety you can still safely eat these vegetables and fruits.
