It's one of the most recognizable expressions around: "An apple a day keeps the doctor away." But besides the fact that it rhymes, which makes it fun to say and easy to recall, does it really have any value? Could the common apple honestly help a person to maintain perfect health?
Vitamin C -- Vitamin C boosts immunity, which helps maintain overall health.
Phytonutrients -- Apples are rich in a variety of phytonutrients, including vitamins A and E and beta carotene.
Apples also act as a toothbrush, cleaning teeth and killing bacteria in the mouth, which may reduce the risk of tooth decay. They're also low in calorie density, one of the trademarks of a healthy food. When a food is low in calorie density you can eat good size portions of the food for relatively few calories.
An apple a day can reduce the risk of diabetes, high blood pressure and many types of cancer. But would you be able to avoid the doctor entirely just by eating a bunch of the forbidden fruit? Not likely. Various studies show health benefits when participants eat an apple between three and five times a week, but all ailments cannot be cured by diet alone.
