Reader Mr. Zhuo 2019-12-8 on "Is it effective to strengthen bone strength? 》's response column describes his experience in taking bone-burning strength. He said: "…There has been normal until now. This is my own experience, but seeing the results of these research published by the professor, it proved that bone strength is invalid, and I was very worried, so I would like to ask the professor to wonder whether there are other coincidences or factors that lead to the effectiveness of bone strength for me?"
Reader Chih-Hao Hsu 2018-12-25, in the response column of "Vitamin D Poisoning, Dog Feed Recall" He said: "Personal experience is that taking vitamin D can reduce the chance of colds and flu. Even if you take it when you are sick, the process will be much shorter, and there will be almost no symptoms of chronic coughing and other infectious diseases."
Reader LoLo 2018-1-31 In "Vitamin D fights cancer, treats cancer? 》's response column describes her experience taking comprehensive vitamins. She said, "About twenty years ago, my left sun acupoint grew a big bubble rash; then my left face often had nerve pain; I may have had an aftermath of the trigeminal nerve when I had a bubble rash; it's really a miracle, combined with certain elements in vitamins, my trigeminal nerve was repaired;"
Ms Zhao Lei, a reporter from Southern People Weekly in Mainland, visited me on May 8, 2019. One of the questions was: "What I am most confused about is that some interviewees mentioned that after taking cranberry capsules, the urinary tract infection quickly recovered and did not recur. Some interviewees said that after taking propolis gel, the allergy on their face that had not been cured suddenly recovered. Or they took grape seed capsules and felt really white, or they took vitamin C for a long time. The average number of illnesses per year was indeed significantly reduced. I checked a lot of information and found that the effects of these health care products were refuted by some doctors at home and abroad one by one. Have you encountered situations where the use of the users and the doctor's arguments and statements were contradictory? What could be the cause?"
Reader King On 2020-1-5, Wind used the website's "Contact Me" to inquire: I would like to ask if Hellenic spiral bacteria need to be treated? I used three-in-one drug six or seven years ago, and it seemed that the number of Hellenic bacteria was reduced and all eliminated. I recently read your book and said that probiotics are mentioned. I want to say that I should not eat them. After not taking them, my stomach starts to feel uncomfortable again. I often feel restless and feel too secreted of gastric acid. I often feel hungry when I sleep at night, and even feel a little pain. I would like to ask Professor Lin whether probiotics can inhibit and reduce Helicobacteria spiral bacteria? (Note: This reader heard from my advice and went to see a doctor. The blood test said that there was no Helicobacteria infection. From this, he felt that the stomach was uncomfortable without taking probiotics, which was a heart effect. In fact, many people have become ill of health products, and they feel that if they don’t eat them, they will not be able to treat them.
The examples mentioned above are patients' own experiences, and in addition you must have heard that some doctors say that patients will recover from their recommended health products (such as vitamin D). So, why do my articles say that health products are not effective?
If you want to answer this question in a complete way, it requires a long discussion and will be difficult to understand. So I will only choose the easiest answer to explain.
First of all, the biggest difference between health products and medicines is that the former is not proven to be effective, while the latter is. Therefore, the law stipulates that if manufacturers say their health products are effective, they will be punished. In fact, in order to avoid being punished, many manufacturers will write such disclaimer in vague small fonts below the company’s page: “These statements have not been evaluated by the U.S. Food and Drug Administration. This product is not intended to be used for diagnosis, treatment, cure or prevent any disease (most people will never notice). In this way, they can promote in other places such as anonymity, alias, or evidence, in other places (such as content farms, faces) that their products can cure all diseases.
A product must pass a clinical trial to prove that it is effective, and at least two trial subjects must be included in the test: the person in the "Test Group" is The product is taken, and the person in the "Control" is taking the consolation agent. After taking the product or consolation agent for a period of time, they need to determine whether their symptoms have improved through a series of tests. If the "Test" improves far higher than the "Test" standard (meets the standard of "Intentionality" in the scientific sense), the product can be said to be proven to be effective.
There are many clinical trials that appear The effect of consolation agents, that is, even though the person in the "Control" takes the consolation agent, he also has improved symptoms. This will make the difference in the degree of improvement between the "Test" and "Control" not meet the standard of the "Intentionality" in the study. In this way, this product cannot be proven to be effective.
"Control Effect" is a constant debate in the medical community. Some students believe that the "Control Effect" is fundamental It doesn't exist, but it's just that people who appear without the test are wrong. But no matter what, many products are declared to be failed (that is, they cannot be proven to be effective).
Since "Consolation Effect" will appear in clinical trials, of course it may appear when individuals take a health product. Therefore, the examples mentioned in this article may be "Consolation Effect". But there will never be an answer to the truth.
Regardless, when I say a product is invalid, I mean it is not proven to be effective through such a clinical trial. And the examples mentioned in this article are all related to this product that does not have clinical certificates. As for patients or doctors who swear that a certain health product is effective, it can only be regarded as "Talk" (i.e., "Talk of the Taoist Words"), rather than "Certification".
Of course, I know that some people may believe in "The Word" (i.e., experiences of themselves or friends, or success stories told by a doctor) rather than believing in "Certification" (i.e., a formal medical report). This, I can only say respect it.
