An apple a day and no doctor needed: Fact or fiction?

Many people know the familiar expression: “An apple a day and you don’t need a doctor.” Although the expression was first coined in 1913, it is based on a Pembrokeshire proverb that originated in 1866. In fact, Notes and Queries magazine was the first to publish the original quote:

Eat an apple before bed and you won’t let the doctor earn his living

In particular, vitamin C acts as an antioxidant, neutralizing harmful compounds known as free radicals and protecting against disease.
Apples are also a great source of antioxidants like quercetin, caffeic acid, and epicatechin.

The effect of apples on heart health
Studies show that eating more apples may reduce the risk of several chronic diseases, including heart disease. One study of more than 20,000 adults found that eating more white-fleshed fruits and vegetables, including apples, reduced the risk of stroke. This may be due to the presence of flavonoids in apples, which reduce inflammation and protect the heart.

Apples are also rich in soluble fiber, which can help lower blood pressure and cholesterol levels, risk factors for heart disease.

Content of anti-cancer compounds
Apples contain several compounds, including antioxidants and flavonoids, that may prevent cancer formation. According to one review of 41 studies, eating more apples was associated with a reduced risk of lung cancer.

Another study showed similar results, where eating more apples was associated with a lower risk of colorectal cancer. Other studies show that a diet rich in fruits and vegetables may protect against cancers of the stomach, colon, lungs, mouth, and esophagus.

However, more research is needed to evaluate the potential anti-cancer effects of apples and to determine if other factors may be involved.
