It’s a saying as old as time—an apple a day keeps the doctor away.

Over the years, many have questioned the validity of this well-known statement. Can one piece of fruit be the key to keeping healthy and well?

While the debate may never truly be settled, researchers from the University of Perugia (Italy) found that people who frequently eat fruit often have fewer tumors. Apples are one of the fruits that boast a large amount of dietary fiber and polyphenol compounds that partner with gut microbes to create an environment that may reduce one’s risk of cancer. This environment is predicted to reduce the risk of several specific cancers, including lung, bowel, mouth, digestive tract, and breast tumors, when compared to people who do not consume apples regularly. The vitamin C in apples also acts as an antioxidant to support immune function and fight cancer cell growth. In addition to preventing tumors, apples may also support cancer recovery. The amount of potassium found in apples can positively affect one’s fluid balance and prevent fluid retention, which is a common side effect of chemotherapy. 

Though eating an apple a day may not be the key to never falling ill, the popular fruit may greatly contribute to one’s overall well-being. Luckily, including an apple into one’s diet is easier than ever. In recent years, apples have become an extremely popular tool in the kitchen. They can be used for breakfast, lunch, dinner, dessert, and of course, a snack between meals.
