Why does the whole world say "an apple a day keeps the doctor away"?This is pretty much the most famous proverb in the world. No matter what age you are born in, you have probably heard this phrase.


Its existence indirectly makes apples the most reliable type of fruit in human hearts. People believed it, and the proverb was well-known as a rhythmic, catchy phrase.


Today, people still sing it thousands of times.


And we all know that a sentence, even a lie, can become the truth to a certain extent if it is repeated enough times.


The same goes for "an apple a day keeps the doctor away".


It's just that people's understanding is a bit biased - in fact, this sentence was born in an earlier era.


As early as February 1860, a British magazine recorded the original form of this sentence. It was only a local proverb in Pembrokeshire, England, and its content was somewhat different from today: "Eat an apple on going to bed, and you'll keep the doctor".


Even at the time, no one knew who its specific creator was, but this did not prevent it from further expanding its influence. After that, the phrase praising the efficacy of apples began to spread quietly and widely, and some small changes were constantly made.


But the main idea remains the same, all emphasizing that "eating apples can reduce doctor visits", such as - "eat an apple to sleep, and the doctor will go to the street to ask for bread".


In the ensuing late 19th and early 20th centuries, the phrase still evolved over time, but became noticeably more streamlined:


"An apple a day, no doctor to pay".


It wasn't until 1913 that the current phrase "An Apple a Day Keeps The Doctor Away" evolved.


However, there is no doubt that apples are rich in nutritional value. Apple is rich in nutrients and contains many nutrients such as sugar, acid, vitamins, flavonoids, dietary fiber, pectin, and mineral elements, which are of high value.


But apple seeds are poisonous. The reason why eating apple seeds is easy to induce food poisoning is mainly because apple seeds contain toxins - "cyanide glycosides", which are plant toxins in a clear sense.
