Always Buy Organic: kale. America's favorite new superfood happens to be hard to grow, despite its hearty and robust nature. Kale attracts different types of crop-damaging insects, so many farmers use heavy amounts of pesticide to control infestations, which can lead to a large concentration of chemicals on your kale salad. If you want to enjoy the health benefits of dark, leafy kale, look for organic or triple wash conventional varieties.
