Apples are an excellent source of fiber. The kind of fiber that apples contain is a soluble fiber called pectin, which is a form of fiber that has cholesterol reduction properties. Apples contain vitamin C and flavonoids. Plants produce flavonoids to protect themselves against infection with bacteria and fungi, and to prevent too much oxidation, which can damage cell structure. Scientists think that humans who eat flavonids may benefit from these properties, and particularly the anti-oxidant properties.
Bruised apples can decay relatively quickly.
You should store apples in the refrigerator where they will last up to 10 times longer than if they were stored at room temperature. You should not store apples in a plastic bag - plastic bags cause them to ripen and rot too fast. Finally, apples absorb odors easily so store them away from foods with strong odors. However, be aware that apple cider contains mostly water. The acidity in apple and orange juice does not prevent bacteria from growing in numbers large enough to make people sick.
