Is it true that an apple a day keeps the doctor away?

You’ve probably heard the saying, “An apple a day keeps the doctor away.”

While the phrase was first used in 1913, it was based on an 1866 Pembrokeshire proverb.

In fact, the original quote was first published in Notes and Queries magazine: “Eat an apple before going to bed, and you’ll keep the doctor from earning his bread.”

Although research suggests that eating more apples is not associated with fewer doctor visits, including apples in your diet can help improve several aspects of your health.

This article investigates whether eating an apple a day can truly help keep the doctor at bay.

Apples have been linked to a number of health benefits that may help promote long-term health.

  • Fiber: 4.5 grams
  • Vitamin C: 9% of the Daily Value (DV)
  • Copper: 5% of the DV
  • Potassium: 4% of the DV

In fact, one study of over 20,000 adults discovered that eating more white-fleshed fruits and vegetables, including apples, was associated with a lower risk of stroke.

This could be due to the presence of flavonoids in apples, which have been shown to reduce inflammation and protect heart health.

Apples are also high in soluble fibre, which may help lower blood pressure and cholesterol levels, two risk factors for heart disease.

Another study found that eating more apples was associated with a lower risk of colorectal cancer.

According to other research, a diet high in fruits and vegetables may protect against cancers of the stomach, colon, lungs, oral cavity, and oesophagus.

More research is needed, however, to assess the potential anticancer effects of apples and determine whether other factors may be at play.
