Every heard the old saying, “An apple a day keeps the doctor away”? It is true! Apples have a lot of nutritional value!
A medium sized apple has only 80 calories (卡). What a great snack choice! Not only is an apple low in calories, they contain absolutely no fat. Thus, eating apples as snacks, as opposed to chips or cakes, will help reduce the risk of cancer.
On top of reducing the risk of cancer, the low sodium (钠) amounts in apples also help reduce high blood pressure and heart disease. They are cholesterol (胆固醇) free. They are also rich in vitamin A, which helps strengthen vision (视力) along with bone and tooth development.
Now that we know the nutritional facts, let’s take a look at some of the fun facts—That’s right! Apples can be fun, as well as healthy!
If an apple is fresh, it will float on water. Twenty-five percent of an apple is air, thus allowing it to float. Can you imagine bobbing (上下浮动) for apples that sink?
And, did you know that an apple is covered with a natural layer of wax (蜡)? That’s what the peeling (剥下的皮) is. It protects the apple’s high water content, keeping the apple fresh.
Apples are a very important part of a healthy diet, but keep in mind they can be fun. And always remember, if an apple sinks in water, pick another one to bob for!
