Apple belongs to rose family and is a kind of fruit that is the most widely grown in the whole world and has the largest production output as well as is delicious with slight sweetness and sour and has abundant nutrition, including various saccharides, lots of microelements, some vitamins, carotene and so on substances in every hundred grams. A kind of American widespread statement goes ‘‘ Eat an apple a meal, let doctor go away.’’ This means that apple is very beneficial for human body, though this sentence is kind of an exaggeration. Today let me inform you of the functions of apple as follows.
Reduce cholesterol content. A French scientific research personnel has gotten a conclusion that eating apple can reduce cholesterol content in the blood and increase the choleresis and the function of bile acid to avoid cholesterol precipitating in the bile to form gallstones through the experiment. Besides, some people have found that the cholesterol content of more than 50% of these people who often eat apple is 10% lower than these people who do not eat apple through the test.
Facilitate feces excretion and check diarrhea. On the one hand, cellulose contained in the apple can soften the faeces within large intestine and abundant organic acids contained in the apple can stimulate gastrointestinal motility and facilitate feces unobstructed. On the other hand, pectin contained in the apple can suppress abnormal peristalsis of intestinal tract and slow down digestion activity to reach the purpose of suppressing laxativeness.
Lower blood pressure. More potassium contained in the apple can combine with redundant sodium salt in the body to make redundant sodium salt excreted to the outside of the body. When people ingest too much sodium salt, they can eat some apples and this is beneficial to balance body electrolyte.
In addition to the above points, phosphorus and iron and so on elements contained in the apple can be easily absorbed by intestinal wall and has the effects of supplementing the brain and nourishing the blood, making people tranquillity and sleeping peacefully. In the meantime, the fragrance of apple is the good medicine of treating depression and sense of repression.
