“An apple a day keeps the doctor away” is a type of idiom in the English language meaning that eating an apple can keep you healthy and help to prevent illnesses. Unlike many sayings, this phrase can be interpreted literally in some cases. Apples are one of the healthiest foods available and regular consumption is linked to a reduced risk of a variety of illnesses. It is thought that the idiom originated from Wales during the 1860s, but, in Rustic Speech and Folk-lore, Elizabeth Wright first used the modern version of the phrase in 1913, which added to its fame. It was then widely circulated throughout the 20^th and still remains popular in the 21^st century.

Idioms add color to the English language, but these sayings are generally not meant to be taken literally though they do tend to have double-meanings. “An apple a day keeps the doctor away” originally implied that keeping healthy will require less frequent visits from a physician. Taken literally, just eating an apple every day won’t keep a person from ever needing to see a doctor. What the idiom does imply is that eating well will keep a person healthier. Other types of idioms have been widely circulated and used in everyday language, such as “nest egg”, “fed up,” and “a piece of cake.”

There are lessons to be learned from the phrase “An apple a day keeps the doctor away.” All apples contain antioxidants, vitamins, and minerals, as well as fiber. Apples also contain vitamin C, which is essential for boosting the immune system, helping the body treat wounds, and maintaining muscles. This type of vitamin is also known for its antioxidant properties, which might help to prevent free radicals from building up in the body that can destroy healthy cells and lead to cancer or other chronic diseases.

The nutritional value of the fruit may be enough to claim that an apple a day keeps the doctor away. The fruit is linked to an increased level of high-density lipoproteins (HDL) cholesterol. This type of cholesterol prevents the build-up of plaque in the arteries. Apples can also decrease low-density lipoproteins (LDL) cholesterol, which is infamous for clogging the arteries and leading to heart disease.

While this idiom is sometimes used by some parents to get their children to eat healthier, it is unlikely that eating an apple every day is enough to literally keep the doctor away. Eating daily sources of fruits can be enough to keep a person healthy, which is what the saying implies. It is unlikely that a person will never need to visit a doctor, but adopting a healthier lifestyle might reduce the number of visits needed.
