apple
"An apple a day keeps the doctor away. Among many fruits, apple is the most common and peaceful one, but its nutritional value should not be underestimated. Chinese medicine believes that it can "promote fluid production and moisten the lungs, strengthen the spleen and stimulate appetite"; Nutritional analysis shows that apple contains the most fructose, and contains a variety of organic acids, pectin and trace elements.
Apple pectin belongs to soluble fiber, which can not only promote cholesterol metabolism, effectively reduce cholesterol level, but also promote fat excretion. The French did an experiment in which a group of healthy middle-aged men and women ate two or three apples a day. A month later, their cholesterol levels were measured, and it was found that 80% of people's low-density lipoprotein cholesterol (LDL, also called bad cholesterol) decreased. At the same time, high-density lipoprotein cholesterol (HDL is good cholesterol) has increased. Apple's help to the cardiovascular system can be seen.
Potassium, a trace element contained in apples, can dilate blood vessels, which is beneficial to patients with hypertension. Zinc is also necessary for human body. When lacking, it will lead to disorder of blood sugar metabolism and decline of sexual function.
Eating apples raw can not only get the above benefits, but also regulate the stomach, because it is rich in fiber and helps to excrete. On the other hand, it is good for people with diarrhea to eat it, because malic acid has a astringent effect, but it should be noted that if it is chronic diarrhea with spleen and stomach deficiency and cold, the apples must be wrapped in tin foil and steamed or simmered before eating.
Apples are rich in nutrition and low in calories, so they are very popular with dieters. In dietotherapy, boiling water with apple peel and ginger slices can stop vomiting. Using apples with pears can reduce the coldness of pears and have the effect of strengthening the lungs and moistening the stomach. In autumn syrup, some apples and pears are used, and lily 1 (30g), Dendrobium 5 (15g) and apricot 3 (9g) are added to moisten the lungs and relieve cough.
