Apples are one of the most popular fruits in the world. They taste great and are very healthy. You might have heard the saying, “An apple a day keeps the doctor away.” But did you know that apples can also help you stay awake?
When we feel sleepy, many of us turn to tea or coffee. These drinks help us stay awake because they contain caffeine. However, apples don't have caffeine. So, how do they keep us awake? Apples contain(含有) natural sugar. An apple has about 13 grams(克) of natural sugar. This sugar helps our blood(血液) move faster and makes us feel more awake(清醒的).
A study shows that caffeine only keeps us awake for a short time. Drinking too much coffee can even be bad for our health. On the other hand, apples can keep us awake for a longer time. They give us energy slowly and steadily. This makes apples a healthier choice.
So, the next time you feel sleepy, try eating an apple instead of drinking coffee. Apples are not only delicious but also good for your health.
