SAN FRANCISCO — An apple's skin is also incredibly nutrient-rich. According to the Academy of Nutrition and Dietetics, apples are loaded with the powerful antioxidant quercetin, which is found predominantly in the skin. Quercetin is a phytochemical with anti-inflammatory and heart-protecting qualities, and may reduce the growth and spread of cancer cells.
Choose apples with the stem intact. Also try smelling them - you should be able to actually smell the freshness.
Apples can stay fresh in your refrigerator for up to three weeks. Keep them in a plastic bag and away from other foods with strong odors.
Consumed whole, apples make for a mess-free and convenient snack. For a more filling option, you can slice them up and dip them into yogurt or your favorite nut butter. Diced apples also make a great topping. Try them with your morning oatmeal or lunchtime salad.
