Reap the benefits and enjoy the peace of mind of eating meals free of pesticides and additives by shopping for healthy ingredients when it counts the most. Below is a list of foods that you should always buy organic.

Root Vegetable: Potatoes
Regular potatoes that are grown above ground are sprayed with pesticides, and the soil they’re grown in is treated with fungicide. By buying organic varieties, you avoid both these threats. In case you can’t find organic potatoes, try sweet potatoes; they are usually grown with less pesticides overall. Organic potatoes cost about $1.49 per pound at grocery stores.

Produce: Peppers and Celery
Both veggies react to pesticides in the same way: like a sponge, absorbing the chemicals through the skin. Because of this, you won’t be able to reduce chemical ingestion by washing or peeling them. Always choose the organic variety. Organic peppers and celery cost between $3.99 and $6.99 per pound at grocery stores.

Leafy Greens: Lettuce, Spinach and Collard Greens
Usually these plants are doused in pesticides to ward off insects. Organic growers use methods like non-toxic repellents to keep these vegetables free of pests. Organic greens cost between $2.99 and $5.98 per pound.

Dairy Products: Yogurt, Butter, Cheese and Ice-Cream
It’s important to go organic with these kitchen staples because we eat so much of them, so often. Non-organic dairy products may come from cows fed a diet of genetically altered  corn, soy, and antibiotics. Organic dairy products can be found at grocery stores and usually cost between $2.19 and $4.29.
