1. Aspirin prevents all diseases.

Some middle-aged and elderly people do not have cardiovascular and cerebrovascular diseases, but take aspirin for a long time. However, they don't know that this is not to protect their health, but because aspirin has side effects and harms their health. Common side effects are abdominal distension, pain, nausea, loss of appetite, and even increase the possibility of upper gastrointestinal bleeding.

Based on a large number of research data, FDA does not recommend aspirin for primary prevention of cardiovascular and cerebrovascular diseases. Unless there are contraindications or serious complications, patients with atherosclerotic cardiovascular disease and people at high risk of cardiovascular and cerebrovascular diseases really need to take aspirin.

Although aspirin is of high quality and low price, its curative effect is exact and trustworthy. However, it is not a panacea for all diseases and cannot be popularized by the whole people. It should be taken under the guidance of a doctor. So people who are not sick should not eat indiscriminately.

2. vitamin c prevents colds.

Some studies have proved that taking vitamin C supplements for a long time may shorten the course of cold or relieve symptoms. But for most people, whether they swallow oranges or take vitamin C supplements orally, they have no effect on preventing or treating colds.

Vitamin C can really help us maintain normal immune function and ensure wound healing. However, there is no conclusive evidence that increasing the intake of vitamin C can enhance immunity and prevent colds.

For taking vitamin C, the best way to prevent colds is to keep exercising every day and have healthy eating habits and living habits. In addition, vitamin C can't be eaten casually. Adults can take up to 2g vitamin C every day, which is included in food. If they take more than 2g, they may have abdominal distension, abdominal discomfort, diarrhea, nausea, vomiting, heartburn, headache, insomnia and even kidney calculi.

3. Oral collagen can beautify the face.

Many people will entrust people to buy American collagen powder. However, no amount of collagen can realize the pursuit of beauty lovers. Skin does contain collagen, which makes the skin smoother, softer, firmer and more shiny by retaining moisture in the dermis. However, the collagen eaten in the stomach will be decomposed into amino acids first, which is no longer collagen, so it has no function of collagen and will not have a "beauty" effect on the skin.

In addition, collagen, as a food, is not a good protein, and it cannot provide all the "essential amino acids" needed by human body. By the way, collagen is basically useless on the face. With such a large molecule, the skin can't directly absorb and utilize collagen.

Raw food is more nutritious than cooked food.

Foreigners prefer to eat raw food, such as vegetable salad; But the Japanese, whose national dishes are all kinds of seafood sashimi, often eat sashimi or something. Eating more of these is better for your health, but you just can't see it.

It is true that heating food will make some nutrients in food lose, such as vitamins, but for raw vegetables, we usually eat more cooked food, which makes up for the loss of nutrients. There are also some foods that are more easily absorbed by the human body after heating, such as lycopene and carotenoids.

For meat, beans and other ingredients with high protein content, as well as starch ingredients such as grains, heating can make them better digested and absorbed, which is usually much more delicious. Another point that cannot be ignored is that sufficient heating can kill harmful bacteria and reduce pesticide residues. From the perspective of food safety, cooking will be better. Of course, it is also a good choice if you can guarantee the hygiene of the ingredients and occasionally want to change your taste, or get used to raw food, salad and sashimi.

5. Cell phone spermicide

In the investigation on whether using mobile phones affects the quality of semen, researchers found that the total amount of semen has nothing to do with using mobile phones. Another study pointed out that 1 hour 900 MHz low-frequency radiation did not affect the sperm motility of healthy men. Some animal experiments show that cell phone radiation has no obvious effect on sperm morphology. The conclusion is that mobile phones will neither emit harmful radiation nor kill sperm.

6. Cancer patients are all cured.

More people die from cancer treatment than directly from cancer. This concept makes many cancer patients worry about regular treatment, and even delays the best treatment opportunity. With the development of medicine, the progress of treatment methods and the research and development of new drugs and methods, the cure rate and survival rate of many cancers have improved.

Of course, a considerable number of cancers, especially advanced cancers, are still difficult to cure. Moreover, whether it is traditional surgery, radiotherapy and chemotherapy or new therapy, there will be some adverse reactions or side effects. Whether to accept treatment or face death calmly requires patients and their families to make a choice, but it needs to be clear that some cancers can be completely cured by early active treatment. For advanced cancer, good treatment is not "completely cured", but to relieve symptoms and improve the quality of life in the future. In any case, it is hasty, wrong and irresponsible to simply say that cancer patients will die because of treatment.

7. You are in a sub-health state and need to recuperate.

The World Health Organization defines health as: health is not only the absence of disease, but also physical health, mental health, good social adaptation and moral health. Strictly speaking, almost no one can fully meet this ideal health standard. And if the state between health and disease is called "sub-health", isn't everyone sub-health? Actually, there is no standard for sub-health. There is no clear definition of a health problem, and its research and related statements are out of the question and untenable.

It is true that quite a few people just feel sick, but they have not found any diseases. How do you explain this? Either there are areas that modern medicine has not recognized, or psychological problems, or these people may already have some risk factors of diseases, which belong to the state of "near disease"-"subclinical"-different from sub-health, subclinical actually has clear medical standards, and it is the early stage of a certain disease, which needs attention, timely treatment and active monitoring.
