Speaking of its origin, it can be traced back to the United States in the last century. At that time, the United States promulgated the prohibition of alcohol, which basically hit the manufacturers who used apples as raw materials for brewing, and thus produced a series of butterfly effects, and apple orchards all over the United States were also hit hard. In order to increase the sales of apples and recover the losses, a witty orchard owner linked apples with medical staff and hung up the slogan "An apple a day keeps the doctor away", which also made later apples a safe fruit in the United States. There are not a few people who still believe this sentence.

There is no doubt that eating apples is good. The nutrients in apples contain many minerals, such as copper, zinc, potassium and iodine. There are many kinds of vitamins, such as vitamin A, carotene, vitamin C, vitamin E and so on. Protein, fat and carbohydrates also exist, so the benefits of eating apples need not be said. Apples are warm, sweet and sour, and almost all women and children can eat them. There is nothing to avoid. Many doctors regard apples as "the first medicine for a gentleman".

Nowadays, under the tide of weight loss, apples are also used to lose weight, and the "three-day weight loss method" is circulating. It is nothing more than using three apples a day instead of three meals a day to control the intake of staple food and lose weight. Seemingly fresh, it is actually a cliche, which belongs to the derivative practice of dieting and losing weight, and is also the biggest misunderstanding of "an apple a day keeps the doctor away".

Because there is dietary fiber in apples, it can lubricate the intestines and decompose fat. Eating apples is good for losing weight, but it can't be used as a staple food. As a fruit, apples have limited nutrients. Although it contains protein, fat and other substances, it is not enough to maintain the body's energy and nutritional needs. Really take an apple a day and three apples a day as a magic weapon to lose weight, and if you don't eat any other food, it may be more direct than losing weight in the long run.
