I think, comparatively speaking, the role of apple is greater. Apple is rich in carbohydrates, organic acids, cellulose, vitamins, minerals, polyphenols and flavonoids, and is called "all-round healthy fruit" by scientists. Apple's health function: lowering blood fat: eating two apples a day lowers blood pressure: polyphenols and flavonoids contained in apples can effectively prevent cardiovascular and cerebrovascular diseases. Prevention of cancer: Polyphenols in apples can inhibit the proliferation of cancer cells. Flavonoids contained in apples are highly effective antioxidants, not only the best vascular cleaner, but also the bane of cancer. Antioxidant effect: Red apples are better than yellow apples and green apples. Strengthening bones: apples contain mineral elements boron and manganese that can strengthen bones. These substances can effectively prevent calcium loss. 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 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. What are the benefits of eating apples? Top ten reasons to eat 1 apple every day: 1 moderate apples contain only 60 ~ 100 kcal of calories, and do not contain fat or sodium. Reason 2: It contains 5 grams of fiber and 20 grams of carbohydrates, which is just suitable for making a dessert. Reason 3: Apple's fiber, pectin, antioxidants and other ingredients can reduce bad cholesterol and increase good cholesterol content.

Reason 6: Tannic acid in apples can protect teeth from tooth decay and gingivitis, and can prevent urinary system infection. Reason 7: Eating 1 apple a day (preferably with skin) can also prevent stroke. Special reminder: Because apples may use a lot of pesticides in the planting process, if citizens do not carefully clean apples when eating them, fertilizers and pesticides stranded on the skins of apples may lead to diseases such as leukemia. Therefore, if you can't guarantee the "naturalness" of apples, it is best to wash and peel them before eating. Reason 8: The vitamins and antioxidants contained in apples can prevent aging. Reason 9: Some effective substances and vitamin C contained in apples can play an anti-cancer role. Reason 10: Apple is rich in folic acid, which is the main component of vitamin B and helps to prevent heart disease. Apples contain much more calcium than ordinary fruits, which helps to metabolize excess salt in the body. 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. Apples have high nutritional value, but we should pay attention to chewing slowly. If an apple can be eaten within 15 minutes, the organic acids and fruit acids in the apple can kill bacteria in the mouth. So eating apples slowly is more conducive to human health. Apple is sweet and crisp, bright in color and rich in sugar, vitamins and minerals. Recently, they have become a sacred product to lose weight. I heard that people who are busy outside often can't eat normally for three meals, so they can take chocolate or candy with them to satisfy their hunger in case they are hungry. Now apples can even replace chocolate and become the best choice for health and temporary filling. As the saying goes, "An apple a day keeps the doctor away!" Why are apples so popular with people who love beauty and pay attention to health? It turns out that apples are rich in soluble colloidal fiber, which can prevent the body from absorbing fat. According to research, eating apples can reduce body fat by about 43%. The gum in apples can absorb a lot of water, soften the digested residue and prevent constipation. If we can keep the digestive system and excretory system unblocked, it will be of great help to the beauty and luster of the skin and the normal operation of the body. Especially the hectic life of modern people, constipation and other digestive diseases have become a common problem. In Huatuo's fruit and vegetable recipes, eating apples can reduce liver fire, stomach fire and large intestine fire, which has a great effect on human excretion and detoxification. Because the cellulose in apples can help maintain the blood sugar level in the body, you won't feel hungry after eating apples, which has the function of preventing and restoring fatigue. At the moment when there are many delicious foods and complicated affairs, it is a great enjoyment for tourists to eat sweet and delicious apple puree or chew a crisp and refreshing apple. "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 the blood of the subjects 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 chances of getting lung cancer can be reduced by 46, and the chances of getting other cancers can 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.
