The Most Chemically Treated Fruits and Veggies You Should Really Avoid

13. Blueberries: A Superfood with a Sour Side

Blueberries, a superstar of the health world, are paradoxically a common source of pesticide residue. Their small size and delicate nature make them difficult to wash thoroughly, and conventional growers often spray them with a variety of insecticides and fungicides to protect the crop. While their antioxidant power is undeniable, the potential for chemical residue can be a cause for concern. Choosing organic blueberries, or buying from local growers who use minimal pesticides, is an easy way to ensure that this healthy superfood is truly clean.

14. Kale and Collard Greens: Superfoods with a Chemical Catch

Kale and collard greens, hailed as superfoods for their dense nutrient profiles, are also notorious for pesticide residues. These cruciferous vegetables are prone to pests like aphids and caterpillars, leading to heavy pesticide use. The Environmental Working Group (EWG) reports that kale often contains residues of multiple pesticides, including Dacthal, which is banned in Europe due to its potential health risks. Despite this, the antioxidant properties and fiber content of these greens make them valuable dietary components. To enjoy their benefits safely, consumers can opt for organic varieties or grow their own in pesticide-free environments.
