In daily life, some false health knowledge has become a superstitious "health motto" for many people through word of mouth. Today, experts from various disciplines at Beijing Ditan Hospital will popularize some common health knowledge misconceptions in daily life. Come and see if you have been "tricked"! Can eating raw fish bile cure diseases? The liver disease department has treated cases of liver and kidney damage caused by poisoning from eating raw fish bile. These patients believe in the folk prescription that "eating raw fish bile can clear heat, detoxify, clear the liver, and improve vision". In fact, the sodium cyprinid sulfate, histamine, hydrogen cyanide, bile acid, and other substances in fish bile can cause damage to human tissues. So eating raw fish bile not only cannot treat diseases, but can also cause poisoning, leading to multiple organ dysfunction and even death. Do patients with gallstones need to be vegetarian? Eating a large amount of high-fat and high cholesterol foods can easily induce gallstones and cholecystitis, so some gallstones patients believe that long-term vegetarianism is a misconception. Long term vegetarianism can lead to a deficiency of fat soluble vitamins in the human body. It can also cause insufficient intake of animal protein and trace elements, and in severe cases can lead to hypoalbuminemia, bleeding, lower limb edema, and even palpitations, fatigue, weight loss, anemia, etc. In addition, fat can promote the secretion of bile, but long-term vegetarianism can easily lead to a decrease in bile secretion and excretion, resulting in the retention, concentration, and accumulation of bile in the gallbladder. The concentrated bile repeatedly stimulates the gallbladder wall, which may actually lead to the formation or aggravation of gallstones. So the most important thing is a balanced diet, and for patients with gallstones, their diet should mainly consist of low-fat and low cholesterol foods. Can holding your breath for 30 seconds test lung health? The ability to hold your breath for 30 seconds is not necessarily related to lung health. Whether the lungs are healthy depends on multiple factors, and few doctors judge a person's lung health solely by holding their breath or climbing stairs. The lungs are composed of many alveoli, and their examination mainly includes the morphology of the lungs and chest expansion, lung function, and pulmonary blood vessels. The health of the lungs generally requires lung function testing. When there are respiratory symptoms or other discomforts, corresponding examinations should be carried out according to the situation, and rumors that lung diseases can be detected by holding your breath for 30 seconds should not be easily believed. Is vegetarianism more beneficial for controlling blood lipids? Simply following a vegetarian diet may lead to insufficient intake of certain B vitamins, which are closely related to the metabolism of fats, carbohydrates, and proteins. B vitamins are mainly found in milk, eggs, animal liver, and fish. Therefore, consuming only vegetarian food may lead to a deficiency of B vitamins, causing disorders in fat metabolism, which may also be one of the factors contributing to blood lipid abnormalities. So if you suffer from high blood lipids, follow the principle of "eating less meat and more vegetables" instead of completely adopting a vegetarian diet, in order to achieve the goal of scientifically lowering blood lipids and maintaining a balanced diet. Pulling out ten strands of white hair? The statement 'the more white hair is pulled out' has no scientific basis. The number of hair follicles in a person is determined at birth, and pulling out hair does not increase the number of follicles or hair volume, nor does it increase white hair. Since that's the case, can you rest assured to pluck out your white hair? Of course not. Doctors do not advocate frequent removal of white hair, especially when there is a lot of white hair, as this cannot reduce the occurrence of white hair and can damage hair follicles, even leading to folliculitis. Recurrent folliculitis may lead to the inability of hair follicles to grow new hair, resulting in "baldness". Is prostatitis a geriatric disease? This is an incorrect statement. Prostatitis is a common disease in the urinary system, especially among men under 50 years old. The young and middle-aged period is a period of vigorous male sexual function, with frequent sexual activity and repeated stimulation of sexual excitement, which can easily lead to repeated congestion of the prostate and induce inflammation. In addition, the young and middle-aged period is the most vigorous period for prostate secretion, providing favorable conditions for the growth and reproduction of bacteria. If personal hygiene is not taken care of, the body's resistance is low, or other nearby areas become infected, pathogens can enter the prostate, leading to acute and chronic inflammation. Will pulmonary nodules necessarily turn into lung cancer? In fact, the vast majority of lung nodules, especially small and micro nodules, are benign and will not develop into lung cancer. Most patients with pulmonary nodules have no symptoms and are incidentally discovered during physical examinations. A study on lung cancer screening conducted abroad showed that among 12029 patients diagnosed with lung nodules during physical examinations, only 144 had malignant nodules, accounting for approximately 1.2%. From the domestic outpatient situation, most patients' pulmonary nodules are also diagnosed as benign. Therefore, when it comes to pulmonary nodules, there is no need to be overly anxious. The most effective and appropriate way to deal with them is to have a professional thoracic surgeon evaluate and diagnose them. Can autumn and winter infusion prevent cerebrovascular disease? Some elderly people are accustomed to administering blood activating and stasis removing drugs during autumn and winter seasons to prevent cerebrovascular disease, but this is actually a misconception. Intravenous infusion not only has no effect on the prevention of cerebrovascular disease, but also has potential infusion reactions due to its direct action in the blood when administered through the bloodstream. The correct prevention of cerebrovascular disease is to develop good lifestyle habits, including regular monitoring of blood pressure, blood lipids, and blood sugar changes, keeping warm, having a reasonable diet, quitting smoking and limiting alcohol consumption, drinking plenty of water, and ensuring fluid balance to reduce the occurrence of cerebrovascular disease. Can drinking more Big Bone Soup after a fracture help with recovery? Is drinking Big Bone Soup beneficial for the recovery and treatment of osteoporosis or fractures? This viewpoint is actually a misconception in daily life. The main content of Da Gu Gu Tang is fat, which cannot directly help us treat osteoporosis and fractures. Its positive effect on recovery and treatment of osteoporosis or fractures is relatively small. In terms of nutrition, for people with weaker physical conditions such as the elderly, drinking more milk, regularly consuming vitamin D and calcium tablets can help increase the calcium content in the body and promote overall health. Is washing healthier? I believe everyone often hears this statement. Some people believe that washing the vagina every day can make it cleaner and prevent vaginitis. In fact, the normal pH value of the vagina is between 3.8 and 4.4. Like the oral cavity of healthy women, there are usually dozens of bacteria breeding in the vagina, but due to the presence of the "guardian" of the vagina, everything is peaceful. The most important "guardian" of the vagina is lactobacilli, which can break down glycogen in vaginal cells into lactic acid, maintaining a certain acidity in the vagina and limiting the proliferation of pathogenic bacteria. In fact, it is good to rinse the external genitalia with clean water regularly. Excessive rinsing can actually damage the vaginal microbiota, disrupt the acidic environment, and make it easier to develop vaginitis. Should kidney disease patients eat low sodium salt? Patients should reduce their sodium intake, so it's better to consume low sodium salt. While this may sound correct, it's actually not true! The reason why 'low sodium salt' has low sodium content is because it contains 30% potassium. Although the intake of sodium has decreased, the potassium content has increased, which can easily lead to hyperkalemia. So although kidney disease patients should consume less sodium, it is best to reduce salt intake from their diet. Does general anesthesia affect intelligence? General anesthesia can affect intelligence This is a traditional and classic misconception, and a question often asked by anesthesiologists. In fact, there is currently no scientific evidence to prove that general anesthesia has an impact on intelligence. Anesthetic drugs, like other medications, undergo a metabolic process. Over time, general anesthesia drugs will be completely excreted from the body through various pathways without causing any residue in the body. With the development of medicine, general anesthesia now tends to use short-lived, reliable, and mild adverse drug drugs, which are quickly cleared by the body after surgery.
