10. Cucumber
Cucumber can be a refreshing and very low calorie snack, but it has a couple of issues in the conventional production arena that make it dangerous. It’s on the Dirty Dozen list, for one, with up to 35 pesticide residues present that are either hormone disrupters or neurotoxins.
They are also usually coated with a synthetic wax to preserve water content and give that smooth, shiny look that consumers crave. It’s not worth it for the aesthetics, though. That wax is made up of chemical contaminants you really shouldn’t be eating. Buy your cucumbers organic.
