1, what are the misunderstandings of diet and health care?
1, blind complement
Make up the wrong direction. Some people realize that they are weak, so they often use tonic drugs such as ginseng wine, Huangqi yam soup and Shenqi essence, thinking that it is beneficial and harmless. Unexpectedly, these things are not available to people with yin deficiency (pale face, nervousness, low fever, night sweats, thirst, red tongue with little coating, insomnia and dreaminess), but they consume yin and body fluids and aggravate symptoms. The above-mentioned tonic, dietotherapy and health-preserving preparations are very effective for people with qi deficiency. These people suffer from asthma, dizziness, spontaneous sweating, loose stools and visceral ptosis (gastroptosis, nephroptosis, uterine ptosis, proctoptosis), and it is symptomatic to use the above tonic. So we should prescribe the right medicine. For another example, some elderly patients with chronic bronchitis often have symptoms of lung yin deficiency (cough without phlegm or sputum is small and thick, sometimes hemoptysis, hot flashes, night sweats, fever in hands and feet, dry mouth and throat). If sweet red ginseng is used, the condition will be aggravated, and American ginseng and Radix Adenophorae should be used to replenish qi, nourish yin and clear heat. For this kind of cough due to yin deficiency, fresh porridge and candied lily should be taken. There are too many benefits. Most elderly people have indigestion and weak spleen and stomach. At this time, if a large number of tonics such as longan meat, prepared rehmannia root and donkey-hide gelatin are used, the digestive function of the spleen and stomach will be weakened, appetite will decrease, and symptoms such as abdominal distension and diarrhea will appear. Therefore, being too tired is also a common problem of tonic. If the elderly do have yin deficiency, it is necessary to use Radix Rehmanniae Preparata, Colla Corii Asini and the like, but also a small amount, not too greasy. It is also a good choice to take a proper amount of rock sugar, Yuzhu soup and yam. Pilose antler can really replenish essence and help yang, and it is a famous yang tonic. If suddenly used in large quantities, it will cause symptoms such as nosebleed, jealousy and dizziness. Therefore, we must master a degree and start from a small amount. Take it for granted Some people think that vitamins are supplements, so it's no harm to eat more. For example, cod liver oil contains vitamin A and vitamin D. When vitamin A is deficient, people will suffer from dry eye and night blindness, and when vitamin D is deficient, it will lead to rickets. But in fact, taking vitamin A from food is enough for physiological needs, and vitamin A deficiency will only appear when they suffer from chronic hepatitis, pancreatitis and diarrhea. At this time, on the one hand, the cause should be treated, on the other hand, vitamin A should be supplemented appropriately. If you take it blindly for a long time, it can cause poisoning, headache, nausea, vomiting, alopecia and itchy skin. If you use vitamin D blindly for a long time, it can cause low fever, irritability, anorexia, hepatomegaly, kidney damage and osteoporosis. Other vitamin drugs should not be blindly taken for granted as tonics. For example, taking a large amount of vitamin C for a long time can cause kidney, ureter and bladder stones. Blind application of vitamin B 1 can cause headache, irritability, arrhythmia, edema and neurasthenia.
2. Abuse of "medicated diet"
In recent years, "medicated diet" has become popular. Once abused, these "medicated diets" are very harmful. It can destroy the normal physiological activities of human body and even cause diseases. Such as ginseng soft candy, velvet antler soft candy, ginseng milk powder and ginseng biscuits. Ginseng can promote the secretion of gonadal hormones, and velvet antler is generally used to treat impotence. If the child eats this so-called "medicated diet" at will, it will make the child precocious, and there will be premature sexual development such as long beard and long pubic hair. There are also some "medicinal foods" (such as some drinks) containing excitatory drugs such as caffeine, which interfere with the biological rhythm of the human body and are harmful to health. Some people make their own "medicated diet". If someone thinks licorice is a good medicine, sweet and delicious, soak licorice in water as tea. This is very dangerous. Taking this "licorice tea" for a long time will produce side effects similar to adrenocortical hormone, which will reduce blood sodium excretion and increase potassium excretion, leading to hypernatremia and calcium deficiency convulsion. What's more, taking licorice for a long time will lead to hypofunction of adrenal cortex. Once there is hypoadrenocortical function, the problem will be more troublesome. Some patients need to take adrenocortical hormones such as prednisone for life to maintain their lives.
3, do not distinguish between appropriate and taboo
In the process of dietotherapy, it is very important to distinguish the food taboos of different people. For example, eating fish, many people think it is suitable for everyone. Actually, it's not. The fish oil contained in fish is mainly eicosapentaenoic acid, which has the effect of inhibiting platelet aggregation and is of great benefit to the prevention and treatment of coronary heart disease and cerebral thrombosis. But it can cause all kinds of spontaneous bleeding, including cerebral hemorrhage, because it reduces platelet aggregation. Research shows that Inuit people eat fish, and almost no one suffers from coronary heart disease and cerebral thrombosis, but cerebral hemorrhage has become an important cause of their death. Therefore, people who have a tendency to cerebral hemorrhage or have a history of cerebral hemorrhage should not blindly eat a lot of fish.
2. What can I eat for health in winter?
1. Winter bamboo shoots: The content of fat, sugar and fiber in winter bamboo shoots is low. Eating regularly can promote intestinal peristalsis, eliminate food accumulation and reduce the absorption and accumulation of fat in gastrointestinal tract. Winter bamboo shoots can be cooked not only with meat, poultry, seafood and other meat raw materials, but also with edible fungi and green leafy vegetables or separately.
2, mushrooms: mushrooms, also known as mushrooms, are edible fungi that people often eat in winter. Lentinus edodes is low in calories and high in protein and vitamins, which can provide various vitamins needed by human body and promote the absorption of calcium in the body. Regular consumption of mushrooms also has a good effect on enhancing immunity and preventing colds.
3. White radish: Radish can be divided into white skin, green skin and red skin. You can eat it raw or cooked. Its vitamin C content is 10 times that of pear, and it also contains interferon inducer, which has antiviral and anticancer effects. Radish is pungent, sweet and cool, and has the effects of resolving food stagnation, resolving phlegm, relieving fever and detoxifying, and is effective for bronchitis and cough.
4. Cabbage: Cabbage is slightly cold, sweet, and has the functions of detoxifying, clearing heat and benefiting the stomach. Anyone who is upset and thirsty, has poor stool and has little urine can often eat cabbage. Cabbage contains more crude fiber, vitamin A, vitamin B and vitamin C, etc. The cellulose in Chinese cabbage can promote intestinal peristalsis, help digestion and prevent dry stool.
5. Garlic: Winter is the most common season for colds. A new study in the UK involved 164 healthy adult participants for 12 weeks. It was found that there were 24 cases of colds in the two groups taking garlic supplements and 64 cases in the two groups taking placebo. The reason is that allicin in garlic can stimulate the growth of white blood cells and enhance the anti-inflammatory ability of human body.
