Norway, a Nordic country located in Scandinavia, has a population of just over 4 million, and its life expectancy and overall national health level have always been among the best in the world. Norway has produced many world-famous scientists, artists, writers and sports stars. The reason why the Norwegian nation won these honors is inseparable from the Norwegian nation's "eating by the sea" ... It is reported that wild cod liver oil has become a "side nutritionist" for Norwegians, especially infants and pregnant women, whether in cities or villages, schools or dining tables.

Commentator: Professor Zhang Jun, School of Life Sciences, Fudan University.

This is a typical far-fetched, seemingly science is actually an idealist thing.

From the biological point of view, whether people are smart or not, or their development in science, art and sports is the result of comprehensive factors. Eating nutrients alone is by no means effective, let alone eating this cod liver oil. If so, there are many places near the sea in our country, and there are even many island countries in the world.

In addition, personal growth or the overall national quality of a country is also a comprehensive factor, which is not only a biological problem, but also involves a series of complex factors such as social environment and historical tradition. In addition, the formation of a scientist or artist is inseparable from subjective factors such as personal efforts and struggles.

The 0. 1 nano technology of nano washing machine does not exist.

Not long ago, a company announced the launch of the country's first washing machine using nanotechnology, which means that nanotechnology has made a substantial breakthrough in the application of household appliances technology. They said, "After ordinary materials are made into nano-scale, their physical and chemical properties will change abnormally and become nano-materials. This material has special functions such as self-cleaning, anti-scaling and anti-friction. The composite outer barrel of the nano washing machine can effectively inhibit the growth of bacteria, clean the outer barrel at any time, and maintain the washing state of' clear water' after long-term use. "

Commentator: Guo Jingkun, Academician of China Academy of Sciences.

At present, the nano-plate in the stock market, the nano-propaganda in the society is too hot, but the real substantive things can't be taken out, and some even say that the nano washing machine is launched, which makes people laugh and cry. This is not conducive to the healthy development of the industrialization of ultra-fine nanotechnology in China.

Hua, Professor of Physics Department of Fudan University.

There are two necessary conditions for the application of nanotechnology. Firstly, all the material particles are less than 100 nm. Secondly, the macro improvement of materials is based on the change of particle size. In addition, the research scope of nanotechnology is 1 to 100 nm, and 0. 1 nm is the size of a single hydrogen atom, so the so-called "nanotechnology" of 0. 1 nm level does not exist.

An oxygen supplement health care product is alarmist, and its credibility is not enough.

Watch out for lack of oxygen! We are troubled by fatigue, irritability, insomnia, loss of appetite, listlessness, headache, dizziness, memory loss, and decreased work and study efficiency. Do you know what caused this situation? Science has finally revealed this phenomenon-lack of oxygen is the culprit! Because our brain is short of oxygen, our heart is short of oxygen, our body is short of oxygen, and our living space is short of oxygen, which makes our health worse ... It can fully meet the overall demand of human body for oxygen, enhance the oxygen-carrying capacity of blood, greatly improve your immune function, and make you energetic and never tired every day!

Commentator: Hong Xiao, master of Shanghai Institute of Pharmacology, China Academy of Sciences, editor-in-chief of Family Medicine.

Healthy people don't lack oxygen. As long as healthy people are not anemic and have low hemoglobin, they will not be deprived of oxygen. The advertisement is very exaggerated, as if everyone is short of oxygen and alarmist.

Too much oxygen can also lead to oxygen poisoning. When oxygen is absorbed too much, free oxygen ions and hydrogen peroxide in the body increase, which are harmful to the physiological function of the human body in many ways.

If all the symptoms and pathological changes are attributed to lack of oxygen, it is enough to supplement oxygen. What do you need doctors and drugs for?

Advertising also avoids the fundamental question in scientific principles, that is, what is the mechanism of action? Is it to supplement oxygen or promote the body to absorb oxygen? Or increase hemoglobin?

A weight-loss product, a special weight-loss drug, hasn't come out yet.

The latest health care product XXX can make you lose weight without burning fat, because it prevents the fat in the food we eat from being absorbed by the stomach and entering the body. So you don't need to get rid of them with the above troubles. It has strong oil absorption characteristics. In the acidic environment of gastrointestinal tract, the fat and cholesterol in food are sucked into a big ball, which makes the gastrointestinal tract unable to absorb, and the fat eaten is excreted with food residue. After taking it, the body can't absorb fat from food, which leads to "fat deficiency" in the body. The body can only use the fat originally stored in the body to lose weight quickly. It only prevents fat absorption and has no effect on other nutrients. Good things in food, such as protein, vitamins and calcium, are still absorbed, which makes you have a strong body and bones.

Really effective diet pills have not yet come out.

At present, there are mainly dextroamphetamine, fluamphetamine, diethylamine benzophenone and various traditional Chinese medicine preparations on the market. The main mechanisms of these diet pills are: inhibiting the appetite center of human hypothalamus, reducing appetite and not wanting to eat, thus reducing calorie intake; Stimulate metabolism, increase the oxygen consumption of the body, increase the metabolism of fat and sugar in the body, thus reducing the accumulation of fat; Stimulate the intestine, thus accelerating the excretion of intestinal contents.

But in fact, a person's obesity is the result of accumulation over time, and it is impossible to lose weight overnight. What is more noteworthy is that the chemicals in drugs can also cause toxic and side effects and even mental dependence.

A skin care product DNA can't be supplemented casually.

Combined with biologists, dermatologists and cosmetics authorities, we extracted high-precision and high-activity sheep placenta anti-aging factors from the fetus and placenta of ××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××

DNA is a biological genetic material. If human skin is supplemented with goat DNA, then people will grow wool. DNA is a bioactive substance, and its biological activity must be guaranteed to realize expression. But its vitality is limited, and it is impossible to survive for such a long time, nor can it be as long as its shelf life. Moreover, if there were DNA factors in it, then this cosmetic would have gone bad and smelly long ago.

In addition, the skin can't easily absorb nutrients because the skin has a protective layer. If this cosmetic can easily penetrate the stratum corneum and enter the dermis, then people's hands will not be the source of all diseases.

In this advertisement, some concepts, such as "supplementing DNA, correcting variation, and restoring the growth of synthetic tissues and cells in protein to normal", have also been deliberately changed and blurred, but it is not clear who to supplement and who to supplement.

Calcium supplement products Not everyone is short of calcium.

If you are strong, you don't need calcium supplements. For young people, because of good physical adjustment, they can hardly feel the loss of calcium, but with the growth of age, the harm of calcium deficiency appears. If you think of supplementing calcium at this time, it will be too late. Strong only covers up the symptoms of calcium deficiency, and when it accumulates to a certain extent, obvious symptoms appear.

The daily diet is enough to provide the calcium needed by the human body. People in China mainly eat cereals and eat less dairy products rich in calcium. The biggest disadvantage of this dietary structure is insufficient calcium supply. In addition, oxalic acid and phytic acid in grains will also interfere with the absorption and utilization of calcium. Therefore, in addition to improving the dietary structure, the most important thing for China people is to choose a good calcium supplement and often make calcium supplements consciously.

Commentator: Gao, Professor, Department of Clinical Pharmacology, China Medical University.

In fact, not everyone is short of calcium. People's normal diet contains enough calcium and generally do not need calcium supplementation. Most people who need calcium supplement refer to certain specific groups, such as some elderly people, infants or some patients who can't eat normally or have malabsorption.

Calcium should not be abused, nor should it be increased in dosage or taken for a long time. Calcium is a substance with strong physiological function. The increase or decrease of calcium ions in human tissues will cause different physiological changes. Excessive calcium intake will reduce children's immunity, make them susceptible to diseases, and more seriously, there will be a risk of hypercalcemia.

A snoring treatment program does not require treatment at all.

About 30% people in the world snore when they sleep. Most people think that snoring is a sign of deep sleep, but it is not. Modern medical research believes that snoring is an abnormal state in human body, which is called "sleep apnea syndrome" in medicine. Because snorers frequently pause every night, the brain is seriously deprived of oxygen over time, forming hypoxemia. Especially middle-aged and elderly snorers, sleep and breathing are repeatedly suspended at night, and cerebral blood hypoxia is serious, which is easy to cause hypoxemia, cerebral hypoxia, cor pulmonale, sudden cerebral hemorrhage, induced hypertension, arrhythmia, coronary heart disease, right ventricular hypertrophy, angina pectoris, myocardial infarction, enuresis, stroke and other accidents. People who snore heavily have more and more apnea time, even from "pause" to "stop forever", and suddenly die in sleep.

Commentator: Bian Youzhen, secretary-general and chief pharmacist of Shanghai Pharmaceutical Society.

This is because the manufacturers deliberately exaggerate the danger of snoring in order to promote their products.

Snoring is a normal physiological phenomenon, which is different from "sleep apnea syndrome". Snoring is neither terrible nor terrible.

The reasons why people snore during sleep are very complicated. Some people snore because of the relaxation of nasal muscles after entering middle-aged and elderly people with age, which leads to certain inhibition of air in and out. Some are hereditary, and some people snore at a young age because of the structural problems of the nasal cavity. There is also snoring when people are tired, which is caused by some changes in the respiratory system at this time. In addition, people will snore because of their sleeping position.

Snoring is a completely normal physiological phenomenon, which is harmless and does not reach the level of drug treatment.

A STD treatment device, two things are said to be the same thing.

Introduce high-tech complete sets of treatment equipment, male and female urologists sit in the clinic, select a series of new drugs with high efficiency for sterilization and antivirus, and standardize the treatment of gonococcal urethritis, nongonococcal urethritis, chlamydia, mycoplasma, viral condyloma, acute and chronic prostatic hypertrophy and laser circumcision. Gynecology: cervicitis, candidiasis, fungal vaginitis, genital herpes, trichomoniasis, increased leucorrhea with peculiar smell, cervical erosion, and difficult diseases of male and female genitourinary system.

Using a large-scale laser therapy machine combined with high-efficiency antiviral immune preparation, adding anti-cancer elements combined with drugs, especially without cross-resistance, laser treatment was carried out on various "condyloma acuminatum", which completely eliminated the virus in the body, inhibited DNA replication, cut off the root cause, and achieved the goal of treating both the symptoms and root causes.

Commentator: Wang Quanpei, medical expert of National STD Control Center.

Sexually transmitted diseases and urinary tract infections are two different things. Urinary system infection is an infectious disease of urinary system caused by conjugated bacilli, Escherichia coli, Staphylococcus and Proteus. Sexually transmitted diseases include syphilis, gonorrhea, nongonococcal urethritis, condyloma acuminatum, genital infection, chancre and AIDS.

There is no name "condyloma acuminatum" in medicine. There are two kinds of diseases related to condyloma acuminatum, condyloma acuminatum and condyloma planum, which are completely different sexually transmitted diseases. Condyloma acuminatum is mainly removed by surgery, freezing and laser, while verruca plana is mainly treated with penicillin for syphilis. After syphilis is cured, condyloma acuminatum naturally disappears, and it will be very dangerous if all of them are treated with laser.

Herpes imperfecta is a sexually transmitted disease. People often say that herpes refers to herpes simplex and herpes zoster. Herpes zoster is herpes that grows around the nose and mouth, not sexually transmitted diseases. Only genital herpes, which grows in genitals, anus and other parts, belongs to the category of diseases.
