Buy Organic: Apples

Buying organic apples is a good use of your organic food dollars, but don't skip apples if you can't buy them organic – just scrub their skins under running water before eating to reduce pesticide residues. Apples are a good source of fiber – like all fruits and vegetables -- and they're also a great source of immune-boosting vitamin C. A medium-sized apple contains around 95 calories, making them a healthy alternative to other sweet snacks.
