Does an Apple a Day Still Keeps the Doctor Away?
Is it true that an apple a day keeps the doctor away? This well-known proverb is thought to originate from the belief that apples have the most curative power of all the fruits.
This is a simple study done to prove the old saying whether it is true or false.
In some parts of the world, it may be the season for apple production. You may be guessing which apple is sweet and tasty by looking at it. However, you will never know its sweetness unless you will try to peel, smell and eat it.
When you buy apples, what do you see at first?
For sure, most of you will see deep red-colored apple, shiny and with good round shape. Probably, you never chose apple that bears green polka dot mark on it, don't you? Actually, the shade of the leaf remains green, which means that the leaves photosynthesize and send sugar property to the fruit. Thus, red with slightly green-colored apple is sweeter than deep red one. But remember that if the apple will mature continuously, the sugar property will increase, taste sweeter, and its green spots may disappear. After all, it is the color you have to learn to find the sweet apple. Probably, you can look at the bottom of the apple, and if it is yellowish, then it is well-ripened and matured. If it is green color, it's midway to maturing.
Scientifically, an apple's chlorophyll component is high when it is still immatured, and is visible in blue and green color. After the chlorophyll amount decreases in the apple, "carotenoid" with the yellow pigment will increase. This has similar phenomenon to that of banana. It starts from blue or green color and becomes yellow. On the other hand, when the light hits the apple, the red pigment called "anthocyanin" increases and you will have difficulties in verifying the sweetness of it. It's the reason that you should look at the bottom of the apple, if it is yellowish. The bottom of the apple has difficulties in getting light.
When you cut a well-ripened apple, there are parts that look like honey in the middle. This is sugar or glucose. However, it turned out that its taste is not as sweet as expected. If you try to inspect the internal constitution of the apple, 60% are made up by substances called "sorbitol", which is the sweetness of the sugar component. This phenomenon is due to the enzymes surrounding the sweetest part of the apple, which means it is well-ripened.
Well, how about the proverb known, "An apple a day keeps the doctor away"? Is an apple a day really does keep the doctor away? Let's take a quantity of Vitamin C in known fruits. Orange, kiwifruit, pear, and other fruits contain more vitamin C than apple. We tried to let our workers to take two apples a day for about 10 days. And we found out that people, who ate apple, increased the vitamin C quantity in their blood for more than 35%, and their bowel movement became better than before. Not only that, they felt better and physically healthy.
Although vitamin C is not mainly included in the apple, why vitamin C increases inside the body when the apple is eaten? The clear reason is not recognized. But what is thought as one of the reason is "pectin" of the dietary fiber. The pectin expands, absorbing the moisture and stimulates the intestine. As a result, intestinal conditions become good, and will be easier to absorb vitamin C. Also the fact that defecation has become good, after eating apples.
You will notice that when an apple is peeled, the inner part will turn to brown after a while. This means that the pectin is reacting when it meets to oxygen. Also, when you heat it for 110 degrees or more, it is verified that the power which eliminates the active oxygen of the apple pectin rises substantially.
Now, we recommend you to take more apples for your daily cooking, such as apple cake, apple salad, apple jam, and apple bread. It is true that an apple a day keeps the doctor away. Good luck and good health to you and your family.
