If your kids eat a lot of produce, you may want to buy organic. A new study found a possible link between ADHD and pesticide levels.
A study in the journal Pediatrics found that kids with higher than average levels of organophosphate pesticides in their urine were twice as likely to have attention deficit hyperactivity disorder (ADHD). However, researchers tested only one urine sample per child, which means they were unable to tell whether a child’s pesticide levels remained constant over long periods of time. While more research is needed to confirm whether pesticides may truly be associated with ADHD, you can lower your children’s exposure to pesticides by choosing organic or locally grown produce. While not organic, fruit and vegetables sold at farmers’ markets tend to contain much lower levels of pesticides than commercially grown produce. Foods with the highest pesticide content include celery, peaches, strawberries, blueberries, peppers, spinach, kale, potatoes, cherries and imported grapes.
