Eight popular dietotherapy methods in the world; Nowadays, people are increasingly advocating healthy and natural treatments, such as treating diseases through diet. Here are the eight most popular dietotherapy methods in the world. Dietotherapy is only useful if it is adhered to for a long time. Recently, patients often ask me, does the so-called "dietotherapy" work? The streets are full of restaurants under the banner of "medicated diet"; Newspapers, the Internet, and TV also publicize every day that eating this kind of food can fight cancer, and eating that kind of food can supplement vitamins. We often follow the map devoutly, but no one can tell whether it has any effect after eating it. 1. Black tea to prevent influenza Japanese scientists soak the virus-infected area with black tea solution with a lighter concentration than ordinary black tea water for 5 seconds, and the virus will lose its infectivity. To this end, the researchers suggest that in the high-incidence season of influenza, people often drink black tea or insist on gargling with black tea water to prevent influenza. 2. Prevention and treatment of diabetes with vitamin B6 It has been reported in France, Italy and Japan that diabetic patients with vitamin B6 below normal value will be given 1 mg of vitamin B6 every day, and symptoms such as numbness and pain in limbs will be alleviated or disappeared after 6 weeks. Eating more foods rich in vitamin B6, such as brown rice, flour, eggs, cabbage and dried yeast, is also effective in preventing and treating diabetes. 3. A recent survey by American scholars found that 31.7% of smokers who suffer from chronic bronchitis never drink milk, while less than 2% of smokers who drink milk every day suffer from bronchitis. A large amount of vitamin A contained in milk can protect bronchi and bronchial walls and reduce the risk of inflammation. Although milk has many benefits, be careful! 4. Royal jelly prevents arthritis. After studying 2 arthritis patients, British scientists have come to a new conclusion: arthritis patients who take royal jelly once a day can reduce their pain by as much as 5% and improve their joint flexibility by 17%. 5. Prevention and treatment of urinary tract infection with orange juice American obstetricians and gynecologists believe that people who are prone to urinary tract infection drink 3 ml of orange juice every day, which is better than drinking water alone. 6. Prevention and treatment of prostate disease with pumpkin seeds A scientific research paper recently published by American researchers pointed out that eating a handful of pumpkin seeds (about 5 grams) every day can treat prostate hypertrophy and obviously improve the third stage of the disease. Because the active ingredients in pumpkin seeds can eliminate the initial swelling of prostate and prevent prostate cancer. 7. Prevention and treatment of colon cancer with starchy foods According to the research of Cambridge University in England, the incidence of colon cancer in Australia is four times that in China, and the main reason is that Australians eat less starch. Experts pointed out that butyrate in starch-rich foods such as bananas, potatoes and peas can directly inhibit the proliferation of bacteria in large intestine and is a powerful inhibitory substance for the growth of cancer cells. 8. Spinach prevents retinal degeneration. A recent study by Harvard University in the United States shows that eating spinach 2 to 4 times a week can reduce the risk of retinal degeneration. It is said that the key of spinach's vision protection is carotenoid, which exists in green leafy vegetables and can prevent sunlight from damaging retina.
