"An apple a day" is a well-known health slogan. Indeed, apples are rich in sugars, organic acids, cellulose, vitamins, minerals, polyphenols and flavonoids, and are called "all-round healthy fruits" by scientists. So, what health care function makes it win such a good reputation? Hypolipidemic: The human experiment of Japan Fruit Research Institute showed that after eating two apples a day, the triglyceride level in subjects' blood decreased by 265,438+0% after three weeks, and the high triglyceride level was the chief culprit of arteriosclerosis. After apple pectin enters the human body, it can combine with bile acids, absorb excess cholesterol and triglycerides like a sponge, and then excrete it. At the same time, the acetic acid decomposed by apple is beneficial to the catabolism of these two substances. In addition, vitamins, fructose and magnesium in apples can also reduce their content. Lowering blood pressure: Excessive sodium is an important factor causing hypertension and stroke. Apples contain enough potassium, which can be combined with excess sodium in the body and excreted, thus lowering blood pressure. At the same time, potassium ion can effectively protect blood vessels and reduce the incidence of hypertension and stroke. Dr Susan Arlich, a famous British pharmacologist, found that polyphenols and flavonoids contained in apples can effectively prevent cardiovascular and cerebrovascular diseases. Prevention of cancer: A study by Hirosaki University in Japan confirmed that polyphenols in apples can inhibit the proliferation of cancer cells. A study in Finland is even more exciting: flavonoids contained in apples are an efficient antioxidant, not only the best vascular cleaner, but also the bane of cancer. If people eat more apples, the risk of lung cancer can be reduced by 46%, and the risk of other cancers can also be reduced by 20%. The latest research by the French National Institute of Health Medicine also tells us that proanthocyanidins in apples can prevent colon cancer. Antioxidant effect: The research team of Cornell University in the United States soaked the brain cells of mice in a liquid containing quercetin and vitamin C, and found that the antioxidant capacity of brain cells was significantly enhanced. Compared with other fruits and vegetables, quercetin in apples is the best, and red apples are better than yellow apples and green apples. Therefore, apples are the best food for patients with Alzheimer's disease and Parkinson's disease. Strengthening bones: apples contain mineral elements boron and manganese that can strengthen bones. A study in the United States found that boron can greatly increase the concentration of estrogen and other compounds in the blood, which can effectively prevent calcium loss. Medical experts believe that if menopausal women can consume 3 grams of boron every day, their calcium loss rate can be reduced by 46%, and menopausal women eat more apples, which is beneficial to the absorption and utilization of calcium and the prevention and treatment of osteoporosis. Maintain acid-base balance: 70% of diseases occur in people with acidic constitution, and apples are alkaline foods. Eating apples can quickly neutralize excessive acidic substances in the body (including acid produced by exercise and acidic metabolites produced by acidic foods such as fish, meat and eggs), and enhance physical strength and disease resistance. Lose weight: apples will increase satiety, and eating before meals can reduce food intake and achieve the purpose of losing weight. As for whether to peel the apple, people have different opinions. Without peeling, it is possible to eat pesticide peeling. The most nutritious part of apple is the skin, and most of the fiber is also in the skin. Apples are rich in nutrition and contain many vitamins and acids. 1 Apple contains more than 30mg of flavonoids, 15% of carbohydrates and pectin, as well as vitamins A, C, E, K and antioxidants. 1 apple (154g) dietary fiber 5g, potassium 170mg, calcium 10mg, carbohydrate 22g, phosphorus 10mg, Vc7.8g, VB 7.8g .. Apple contains much more calcium than ordinary fruits. Malic acid can metabolize calories and prevent obesity in the lower body. As for soluble fiber pectin, it can solve constipation. Pectin can also promote the excretion of lead, mercury and manganese in gastrointestinal tract, regulate the blood sugar level of human body and prevent the sudden rise and fall of blood sugar. German scientists have found that pectin in apples can lower cholesterol. After a long-term investigation, Dutch scholars found that people who eat 1 apple every day have increased bile excretion and bile acid concentration, which is helpful for the liver to excrete more cholesterol. Polyphenols and flavonoids contained in apples are natural chemical antioxidants, which can remove the metabolic "garbage" in the body in time. Eating ripe apples can cure constipation. Eating chopped raw apples can prevent mild diarrhea with pectin. Malic acid can stabilize blood sugar and prevent senile diabetes, so diabetics should eat sour apples. Apple contains sugar, lithium and bromine, which is an effective sedative and hypnotic without side effects. Apples contain zinc and magnesium, so eating apples often can enhance memory and promote children's development. Because some elements in apples can eliminate lead and mercury harmful to health, European scientists call apples anticancer drugs. Eating apples should be chewed slowly, which is not only conducive to digestion, but also conducive to oral hygiene and reduce human diseases. According to botanists' experiments, if an apple takes 15 minutes to finish, the organic acids and fruit acids in the apple can kill 99% bacteria in the mouth. So eating apples slowly is very beneficial to human health. Different ways of eating will produce different effects. 1, it's best to eat raw without skin, and dip in some sugar if the sweetness is not enough. It can relieve symptoms of yin deficiency and heat deficiency caused by upper respiratory tract infection, such as dry throat, hoarseness, dry cough with little phlegm, constipation, short drowning, sore and toxic attack, polydipsia, etc. 2, cooked food can be cooked after peeling, or cooked with jujube, radish, mung bean, etc. Eating and drinking, treating diseases and keeping in good health have better effects; Buy some pears, unscrew the cover around Baer Er, take out the seeds, pour in honey, then cover them, steam them on a plate, and eat one in the morning and one in the evening, which has a certain curative effect on tracheitis.

Steamed pear with rock sugar is a traditional food supplement in China, which can nourish yin and moisten the lungs, relieve cough and resolve phlegm, and has a good moisturizing and protective effect on the throat. There are also several medicated diets about pears: 1, hypotensive: 1 pear and 1 tomato, peeled and cooked in a pot, and eaten/kloc-0 times a day for 20 days, which can nourish yin and clear heat, and has the effect of preventing and treating early hypertension. 2, liver protection: use 1 pear, wash and slice, use 3 pieces of willow branches to decoct with water, drink soup and eat pears, once a day 1 time, can cure infectious hepatitis.

Although pear is a good fruit, it should not be eaten too much at a time because of its cold nature, so as not to affect the spleen and stomach. Therefore, people with cold cough, abdominal pain and spleen deficiency in loose stool should be careful to eat. Banana is a cool fruit. Eating too much will damage gastrointestinal function, especially for people with deficiency and cold. For example, bananas are rich in potassium salt, but if nephritis patients eat too much, it will aggravate their condition. Banana: Banana contains a lot of cellulose and iron, which has the function of relaxing bowels and enriching blood. Mother loves to stay in bed, has poor gastrointestinal peristalsis and is often constipated. In addition, postpartum blood loss is more, and blood needs to be supplemented, and iron is one of the main raw materials for hematopoiesis, so eating more bananas can prevent postpartum constipation and postpartum anemia. Although there are some restrictions on eating bananas, their rich nutrition also has great therapeutic value. The following is the diet method of bananas for your reference: 1. Treatment of gastric ulcer: eat a banana before meals every day, and continue to eat it will have a good effect. Second, prevention and treatment of arteriosclerosis and hyperlipidemia: use brewed tea, mix it with mashed banana paste, add a little sugar, drink a cup after three meals a day, and eat it regularly.
