The New Dirty Dozen Is Out: 4 Things To Do If You're Worried About Pesticides In Your Food

At the start of each spring, the latest Dirty Dozen and Clean 15 come out to shake up grocery lists everywhere.

Compiled by the Environmental Working Group, these lists use the latest USDA data to name the fruits and vegetables that tend to have the most and least pesticide residue (after they've been given a good washing, to reflect how people actually eat them at home). After analyzing data on 46,569 samples of nonorganic fruits and veggies, the watchdog group announced that carrots have knocked off cantaloupe for a spot on the Clean 15 list, while blueberries and green beans are the latest adds to the Dirty Dozen.

Blueberry lovers are up in arms, but why does pesticide residue really matter, anyway? While chemical pesticides effectively protect crops from pests, weeds, and mold (we would have far fewer produce options, and they would be far more expensive, without pesticides), they do have their downsides. The use of chemical pesticides on farms can harm surrounding biodiversity1, pollute nearby waterways2, and harm soil strength and microbial diversity3. The consistent use of some pesticides can also threaten farmworker health4.

From a shopper's perspective, eating a nutritious diet that's low in pesticide residues has been associated with some tasty health outcomes. In newly published research5 that monitored the health of more than 150,000 people for over 20 years, those who ate a diet rich in low-pesticide fruits and vegetables had a 36% lower mortality risk than those who ate hardly any fruit or veg—while eating a diet rich in higher pesticide produce did not seem to have any impact on mortality.

If your grocery budget allows you to buy all organic produce, by all means, do. But if record-high food prices have you looking for opportunities to save, the Clean 15 list is a solid place to start.

Avocados, sweet corn, pineapples, and onions are a few of the ingredients that tend to have very few detectable pesticides, so you can get away with buying them conventional and just giving them a good rinse when you get home. Note that most of the produce on the Clean 15 list is covered in a tough outer peel, husk, or shell that protects the inner edible part from pesticides; makes sense! This is an easy thing to remember the next time you're shopping and don't have the list handy.

If pesticides are a concern for you, you'll want to shell out for organic versions of strawberries, spinach, kale, peaches, pears, and other produce that made this year's Dirty Dozen list. Ideally, you'll also buy these items from local (within 400 miles or so) farms while they're in season, to reduce their time in transit.

Fruit and vegetable supplements make it easy to sneak more plant-based nutrition into your meals. Typically made from plants that have been dried for a powder or capsule, they can help you fit a wider array of nutrients and phytonutrients into your diet.

Finally, peeling your produce can help you avoid any lingering pesticide residue. But remember that all parts of a plant, including the peels, have something to offer. And sometimes, the outer layer is actually the most nutritious (did you know 30-40% of a potato's fiber is found in its skin?).
