The old saying goes: an apple a day keeps the doctor away. Have you ever wondered what gives this fruit such a popular and healthy reputation? Apples are packed with vitamins, minerals, and fiber and are a good quick source of energy. Additionally, apples consist of about 85% water, making them a thirst-quenching, portable snack. Apples come in many different sizes, shapes, and colors, but an average medium-sized apple contains only about 95 calories.
A medium-sized apple provides 4 grams of dietary fiber. Interestingly, nearly half the fiber, both soluble and insoluble, is found in the peel. Pectin, a kind of soluble fiber found in an apple peel, has been shown to help prevent cholesterol buildup in the arterial wall, reducing the risk of heart disease. The insoluble fiber in apples aids in the smooth transit of food through the digestive system, which promotes gut health and regularity.
Apples are a rich source of flavonoids and phenolics—types of phytonutrients found in plants. Both flavonoids and phenolics have been shown to protect against chronic diseases such as cancer and heart disease. Apples have the second-highest antioxidant levels found in common fruits after berries. The antioxidants, which are found in the pigments of the apple peel, may help reduce oxidative stress to the cells, prevent chronic diseases, and slow the aging process. Several studies have shown that apples not only decrease the risk of chronic diseases, but they are also associated with lowering the risk of Type 2 diabetes.
How to Store Apples
Apples ripen 8 to 10 times faster when stored at room temperature than when refrigerated. To increase the usable life of apples, store them in plastic bags with holes in the produce drawer of your refrigerator. Apples should be stored away from other produce since they give off ethylene gas, which promotes the ripening of other produce.
