Are cancer prevention and anti-cancer health supplements really reliable? Cancer has become a common disease, and people generally talk about cancer, so how to prevent and cure cancer is an issue of great concern to many people. In fact, there are a set of norms for cancer prevention, early diagnosis and screening, and cancer treatment and rehabilitation. However, many people always go astray or even take the wrong path, that is, they believe in the so-called health care products. There are many kinds of health supplements in the market, some claim to prevent cancer, some claim to cure cancer, and some claim to improve immunity, as if there is no cancer that cannot be prevented or cured. Is this true? Are these health supplements effective or not? Can they really prevent and fight against cancer? Let’s understand the ingredients of health supplements first. All the so-called health supplements are composed of vitamins (vitamin A, C, E, folic acid, coenzyme Q10, etc.), minerals (trace elements and macronutrients, such as molybdenum, selenium, calcium, zinc, etc.), some natural plants or rare plant extracts (such as red bean extract, ginkgo biloba extract, hawthorn extract, etc.), some valuable plants and animals or rare plants and animals (such as ganoderma lucidum, wormwood, ginseng, deer antler, turtle, etc.). ginseng, deer antler, turtle, pangolin, etc.), marine biological extracts (such as deep-sea fish oil, bonito extract, etc.), and so on. It must be admitted that some of these ingredients, after some studies (mainly in vitro and animal experiments), suggest that they may have anti-cancer effects, and this is the “highlight” that businesses seize to promote. If someone raises an objection, the company will usually produce the so-called research evidence and say in a dignified manner that it has been scientifically studied. This is certainly not the case! In essence, most of the so-called health food products are actually “food”, not “medicine”. The legal health food box should be marked with “G + 4 digits of the age number + 4 digits of the sequence number (domestic), or J + 4 digits of the age number + 4 digits of the sequence number (imported)”, and drugs should have an approval number, and the box should be marked with “G + 1 digit of the letter + 8 digits, and imported drugs with 1 digit of the letter (imported). Imported drugs are 1 letter (H, Z or S) + 8 digits”. However, many health food companies will deliberately confuse the concept of health food and drugs in their promotion, obviously food, but advertised as the efficacy of drugs. At the present stage, there are very few drugs (i.e. “tumor chemical intervention”) with clear cancer prevention effects, and only aspirin (used to prevent certain colorectal cancers), tamoxifen (used to prevent certain breast cancers) and a few other drugs are officially approved. You can’t even claim that a drug can prevent and cure cancer, let alone that it can be a “food”! The so-called “anti-cancer or anti-cancer supplements” are actually more of a concept hype, they do not have any anti-cancer or anti-cancer effect at all, you can eat them as food, or as nutritional supplements for people with nutritional deficiency (but not more). Remember: supplements are just food! Some people may say, if there are experimental studies to support it, why do you say it has no cancer prevention and anti-cancer effect? As I said before, it cannot be denied that some studies (mainly animal experiments) have found that certain foods contain anti-cancer ingredients, but you should not hope to prevent cancer simply by eating foods or supplements that contain such ingredients. First of all, experimental research is conducted to extract a certain ingredient from this food, and then a certain dosage is used to conduct experiments on animals, in order to achieve this anti-cancer effect, how much of this food or health food do you have to eat? In order to achieve this anti-cancer effect, how many of these foods or supplements do you have to eat? But if you don’t eat the amount that will kill you, you won’t be able to achieve the anti-cancer and anti-cancer effect as stated in the experiment. Therefore, theoretical or experimental studies suggesting the presence of anti-cancer ingredients do not mean that eating such things containing anti-cancer ingredients can fight cancer. Some people say, “I am taking extracts or concentrates, so I should be able to achieve this anti-cancer and anti-cancer amount. If you do take a lot of them, it may be possible to achieve the so-called “effective amount” in the experiment, but we must pay attention to the fact that eating too much of them will bring harm to health, including harm to liver and kidney. Do not consume a large amount of these health supplements for the so-called cancer prevention and anti-cancer purpose. No health supplements have been studied in regular human studies to be able to prevent and fight cancer. There are many drugs that are theoretically useful, but the final human clinical trials eventually confirm that they do not work, not to mention these health supplements that are essentially just food. Of course, you can eat in moderation, but this is no different from your normal diet, so why spend extra money to buy? Some people still don’t give up, so there is always some effect, right? Food, or as nutrients, the so-called health products of course more or less useful, but you eat radish and cabbage is also good for the body, eating is also good for the body, why do not you say? Unless people who lack certain nutrients are confirmed to be in need of special supplements under the guidance of doctors after examination or epidemiological studies, it is not necessary for the general public to eat properly. Regarding the relationship between diet, nutrition and cancer prevention, the American Cancer Society releases a report every 5 years, in which it is mentioned that there is no conclusive evidence that various vitamin supplements have significant cancer prevention or anti-cancer effects, and it is recommended that they should be taken from natural foods such as vegetables and fruits rather than from so-called health supplements. Multivitamin and mineral supplement pills also have no anti-cancer effects, and natural foods are the best source for consuming these substances. After reading this authoritative cancer society’s recommendation, do you still think these supplements can prevent and fight cancer? But why do the people believe in these supplements so much? The main reason is that people lack basic medical knowledge and are easily fooled by the seemingly “grand” propaganda of businessmen. Of course, businessmen are really good at fooling, good at concept hype and propaganda marketing, and they take advantage of the general psychological fear of cancer, the people have the psychological demand of cancer prevention and anti-cancer, but they can’t find credible cancer prevention science, even if the doctors promote cancer prevention and anti-cancer methods, most of them hold an objective and neutral point of view and seem to be ambiguous, not exaggerating or saying it with conviction. However, common people like to hear “sure” words, such as “XXX can definitely prevent or cure cancer”, doctors do not say so, but businessmen like to use such sure words for their own profit. In addition, Chinese people have always been superstitious about tonic medicine and tonic products, and they like to buy health care products when they give gifts or visit the sick, which has a lot to do with the advertising on newspapers and TV. Many people just “listen to what people say”, or purely follow the trend, others eat, I also eat, with the mentality of eating in case it works. What is the reliable way to prevent or fight against cancer? This question is too big to be explained in a few words. In terms of diet alone, different foods have different nutritional value, the key is to be balanced, partial diet is the big taboo, to be diversified, vegetables should be diversified, not only green leafy vegetables, to include vegetables of different colors (green ones such as bok choy, red ones such as tomatoes, orange ones such as pumpkins), but also fruits and melons, fruits are recommended to be consumed directly with complete water check, do not always rely on juicers, cereals and proteins should also be Diversify, with a full range of nutrients, reduce refined sugar and saturated fat intake, and control salt intake. A balanced diet, well-matched, and good eating habits are among the core strategies for cancer prevention. Based on research evidence, the World Cancer Research Fund and the American Institute for Cancer Research have proposed some clear and easy-to-implement effective cancer prevention measures, including: losing weight as much as possible without becoming underweight; avoiding sugary drinks and limiting the consumption of energy-dense foods (especially processed foods that are high in sugar or low in fiber or high in fat); consuming more vegetables, fruits, whole grains and legumes; and limiting the consumption of red meat (such as beef, pork and meat). Limit the consumption of red meat (such as beef, pork and lamb) and avoid processed meat; limit alcohol consumption; limit salt (sodium) intake; and do not use supplements to prevent cancer. Note that one of them is specifically mentioned in a separate article, do not use supplements to prevent cancer, the so-called supplements are all kinds of so-called health care products, you see the world’s leading cancer institutions have clearly recommended not to use supplements to prevent cancer. For example, they may say that even if you say that taking these supplements has no clear effect on cancer prevention, it can at least improve immunity, but there is no clear evidence for this. If you have to say that there are some benefits to immunity, eating food is also good for immunity, so why spend money or even high prices to buy these health products? The actual food is not a good idea. When it comes to taking care of immunity, there are many simple things you can do in life to help take care of immunity, such as, resolutely give up a bad lifestyle, quit smoking and limit alcohol, do not sit still, do not often stay up late, avoid overwork, combine work and rest, adhere to exercise, maintain a proper weight, a balanced and diversified diet, stay away from junk food and so on these, put no money “tonic body The “method” does not want, must toss what tonic tonic. Do not believe in what “natural”, “no side effects”, “improve immunity”, “certainly effective”, “ancestral or exclusive formula”. The “ancestral or exclusive formula”, “cure for all diseases or cancer” and so on and so forth. You should be cautious about any health care products, even if you have money, do not be capricious, spend the money may not buy any benefits, and may even be harmful. The way to “replenish your body” is in you, not in taking health care products.
