Hidden Pesticides: Which Vegetables Are the Worst Offenders?

15. Dates: A Sweet Treat with a Hidden History

Dates, with their rich, caramel-like sweetness, are a dietary staple in many cultures. However, conventional date palms are frequently treated with pesticides to protect against pests like the carob moth. Since dates are harvested and consumed whole, without any peeling or washing after they're dried, any lingering chemical residues are ingested. The sticky, textured skin can also trap dust and pesticides. For a truly clean snack, look for organic dates or wash them thoroughly before eating.

16. Quince: A Hard Fruit with a Soft Underbelly

The hard, tough skin of a quince might suggest it’s well-protected from chemicals, but this fruit is often heavily sprayed to combat pests like the codling moth. Since quince is typically cooked and not eaten raw, some people assume it's safe. However, the skin is often left on during cooking, and residues can persist. To reduce your exposure, peel the quince before cooking or choose organic varieties, especially if you plan to use it for jams or jellies.
