Which of these typically containers higher toxin levels when conventionally farmed?

  1. Grapes
  2. Avocados
  3. Kale
  4. Asparagus

Answer: c. Kale

Kale, and hot peppers are often treated with unusually toxic chemicals. Though other items on EWG’s ‘Dirty Dozen List’ have a wider variety of chemicals or higher concentrations, it is worth noting that leafy greens often contain exceptionally toxic insecticides and weed killers that are no longer used on other produce.
