Watermelon juice is sweet and delicious, and its pulp contains glucose, fructose, sucrose, vitamins, various amino acids, malic acid, pectin, glucoside, etc., which are all essential nutrients for human body. Watermelon can prevent heatstroke and refresh oneself for many reasons. First of all, people can get more water by eating watermelon than by eating other melons. Secondly, although watermelon does not contain more inorganic salts than other melons and fruits, people eat more watermelon in summer and get more inorganic salts, which is of great benefit to supplement the salt lost due to sweating. Especially for patients with anorexia due to fever, watermelon can not only supplement nutrition, but also cool and quench thirst and stimulate appetite. All thermal diseases, eating watermelon has a certain effect. Therefore, since ancient times, there has been a saying among the people that "half a melon in summer keeps the medicine away". The ancient Zhang Lu said that watermelon "can induce pericardial heat and excrete it in the small intestine and bladder; It can relieve the thirst of sun Yangming and fever, so it is called' natural white tiger soup'. At the same time, the medicinal effects of "Compendium of Materia Medica" on watermelon are summarized as follows: "Eliminate vexation and quench thirst, relieve summer heat and treat laryngitis; Broaden the middle and lower the qi, benefit the small, treat blood dysentery, relieve alcohol poisoning, and treat mouth sores. "Modern medical research on the therapeutic mechanism of watermelon shows that watermelon contains citrulline and arginine, which has a good diuretic effect, and folic acid also has hematopoietic function in the human body, which has a certain curative effect on blood diseases such as anemia. In addition, watermelon contains a lot of pectin and cellulose, which is beneficial to food digestion and has a good curative effect on digestive system diseases and constipation. It can also eliminate obesity and overnutrition. Watermelon pulp juice contains protease, which can transform insoluble protein into soluble protein. A small amount of salt is beneficial to the treatment of nephritis. Watermelon Cui Yi (melon peel) has a better diuretic effect than pulp juice, and can be used to relieve summer heat, moisten intestines, neutralize and quench thirst. It is an important medicine for intestine, stomach and spleen, and also has the function of lowering blood pressure and relieving acute cystitis.

Europeans say, "An apple a day keeps the doctor away. "The American Reader's Digest ranked the ten most healthful fruits, and Apple ranked first. First, the magical "apple phenol": Apple contains a kind of polyphenol, which is easily soluble in water and thus easily absorbed by the human body. The "apple phenol" in high-quality red Fuji is higher than that in ordinary apples 10%-20%. This magical "apple phenol" has seven functions: first, it resists oxidation and keeps food fresh; The second is to eliminate odor, which can remove fishy smell and bad breath; The third is to prevent tooth decay; Fourth, it can inhibit the production of melanin and enzymes; Fifth, it can inhibit the occurrence of reactive oxygen species and prevent various lifestyle diseases caused by reactive oxygen species; Sixth, it can inhibit the rise of blood pressure and prevent hypertension; Seventh, it can inhibit allergic reaction and has certain antiallergic effect. Second, slimming and detoxification: Fuji apples contain more "pectin" than ordinary apples, which is a kind of water-soluble dietary fiber, which can reduce the number of bad bacteria in the intestine and help beneficial bacteria to multiply, thus improving the flora in the intestine. The once popular "Apple Diet" is used to make people feel full and regulate the intestines, so as to achieve the effect of losing weight. Now many Americans regard apples as a necessity to lose weight. They go on a diet one day a week and eat only apples. This day is called "Apple Day". Beauty beauty: Fuji apples are rich in vitamins. Among all fruits containing vitamin C, the content of apples is the highest-about 100g Fuji apples contain vitamin C 10mg ... Vitamin C can effectively inhibit the formation of skin melanin, help eliminate skin spots, increase heme and delay skin aging. American researchers have also proved that "taking vitamin C directly from fresh fruits is more effective than taking oral drugs". Eating a red Fuji every day can meet most of the vitamin C that the human body needs every day. Decompression and oxygen supplement: Modern people ingest too much protein in their daily diet, and these protein are broken down into amino acids, which makes most people's body fluids "acidic". Acidic body fluids will continue to accumulate in the body, making people feel tired and weak. Among fruits, apples contain the most complete nutrition, including polysaccharide, potassium ion, pectin, tartaric acid, citric acid and so on. It can neutralize acid radicals in acidic body fluids, reduce the acidity in body fluids, and thus relieve fatigue. And its rich zinc content is the component of many important enzymes in human body, which can eliminate fatigue and enhance memory. V. Health and cancer prevention: A research report published by Finnish researcher 1999 10 shows that flavonoids contained in apples are effective substances to reduce the incidence of cancer. People who eat apples regularly have a 46% reduction in the incidence of lung cancer and a 20% reduction in the incidence of other cancers. A research report in Nature, sponsored by new york Apple R&D Project and new york Apple Association, also shows that eating an apple a day can effectively prevent cancer. 6. "General practitioner": As early as in ancient Egypt, people regarded apples not only as a food, but also as a medicinal material. Canadian research shows that apple juice has a powerful killing effect on infectious viruses in test tubes, and people who eat more apples are far less likely to catch a cold than those who don't eat or eat less. Therefore, some scientists and doctors call apples "all-round healthy fruits" or "general practitioners". @ @ @ @ @ @ @ @ As a fruit, papaya is actually papaya, also known as pumpkin, pumpkin and Xanthoceras sorbifolia.
