The Dirty Dozen and Clean Fifteen
The Dirty Dozen and Clean Fifteen

The Environmental Working Group (EWG) releases an annual list of the fruits and vegetables with the highest pesticide residue levels (dirty dozen), along with a list of the cleanest fruits and vegetables (clean fifteen) that contain little to no pesticides for that specific year. The EWG has estimated that consumers can reduce their exposure to toxic pesticides by 80% just by buying these 12 foods organic.

It is important to avoid pesticides because they pose serious health risks, especially to children and adults with health concerns. Pesticide exposure has been shown to cause neurological health effects such as memory loss, loss of coordination, and reduced visual ability; among others. Other health effects include hormone disruption, asthma, allergies, hypersensitivity, and an increased risk of cancer.

Keep in mind that even after being washed or peeled, pesticides were still present on fruits and vegetables tested by the USDA.
