Whether or not to eat health care products, we must first understand the true meaning of health care products.
First, the concept of health care products
The Chinese nation has a long tradition of dietotherapy and health preservation. For thousands of years, in the practice of fighting various diseases, the Chinese nation has constantly summed up and formed a unique traditional medicine, accumulated a lot of health care experience, and formed a health care theory with China characteristics. The ancient theory of "homology of medicine and food" is actually the viewpoint of health food.
At present, the concept and classification of health food are not exactly the same in all countries in the world, but the food academic circles agree that health food should be composed of natural nutrients and special functional substances. Health food (English name "functional food") refers to food with specific health care function, that is, food suitable for a specific group of people, which has the function of regulating the body and does not aim at treating diseases.
China's "Measures for the Administration of Health Foods" stipulates that health foods refer to foods with specific health care functions. This definition not only reflects the recognition of the traditional "food supplement theory" in China, but also gives a clear definition of health food with modern scientific concepts.
Health food must be food first, and it must be non-toxic and harmless. We can say that it has two basic characteristics:
First of all, it is safe and will not cause any acute, subacute or chronic harm to human body.
Second, it is functional, which has a certain regulatory effect on specific people, and cannot cure diseases, nor can it replace the therapeutic effect of drugs on patients.
Second, why do people who take medicine need to supplement nutrition?
In fact, drugs can also cause a large loss of nutrients, including steroid drugs for asthma and rheumatoid arthritis, drugs for epilepsy and drugs for thyroid diseases.
(1) Antiepileptic drugs can also hinder the absorption of folic acid.
(2) Taking antibiotics for a long time will lead to the loss of vitamin B and vitamin K, which will affect the gastrointestinal function.
(3) People who take aspirin for a long time tend to lose vitamin C..
(4) Cold medicine and painkillers can reduce the content of vitamin A in blood.
(5) Lutein in contraceptives will hinder the action of vitamin B6 and the absorption of folic acid.
(6) Sulfonamides and cholesterol-lowering drugs will affect the absorption of folic acid.
(7) Diuretics and laxatives taken by patients with hypertension and nephritis will lead to a large loss of calcium, potassium and vitamins in the body.
(8) People with gastric ulcer and hemorrhagic anemia should pay attention to supplement trace element iron when taking antacids and alkaline drugs.
It can be said that drugs have always been the "bane" of nutrients.
If you are not short of nutrition, taking medicine will make you lose nutrition.
If you lack nutrition, taking medicine will aggravate the symptoms of nutritional deficiency and produce toxic and side effects. In any case, taking medicine and nutrition together is the best way to be safe.
Third, the types of health care products.
In China, the research on dietary nutrition is slower than that in western developed countries. After the reform and opening up, the development of nutritious food in China has gone through different stages. Through the investigation of more than 3,300 kinds of health foods, we put forward a new classification method of health foods in China, which is divided into five categories with time as the vertical axis and raw materials and technological standards as the horizontal axis.
The first category: non-high-tech technology, raw materials are rough natural sources. Such as early primitive spirulina, simple processed medicinal liquor, fruit processed products, etc. , large side effects, poor sanitary conditions, containing harmful bacteria; Lack of long-term use history, some of them also contain arsenic (arsenic component), lead, mercury, silver and other metal components after testing. These health foods are shoddy and have a bad influence, so they can be called "robber health products".
The second category: high-tech production, raw materials for chemical synthesis. For example, estrogen capsules and vitamins synthesized from some chemical raw materials in the United States only have short-term animal use experiments and lack long-term clinical verification. A follow-up survey conducted by the National Health Service for more than ten years shows that 80% of women who take synthetic estrogen suffer from breast cancer and cardiovascular and cerebrovascular diseases. The fundamental reason is that the raw materials of this kind of products are taken from petroleum, coal and other chemical raw materials, and the structure and system acceptance of human body is not high, which can play a therapeutic role in the short term, but it is easy to produce toxic and side effects in the long term; Strictly speaking, it can't be called nutritional health food, and it belongs to the category of drugs. The organ foundation of the human body is an organic whole composed of various nutrients, and the drugs synthesized by the chemical industry cannot provide the human body with the nutrients needed by the body. Being sick is like a broken leg of your stool, and you need wood to decorate it, instead of propping it up with stones to continue sitting. Stone is equivalent to medicine, and wood is equivalent to nutrition. For patients, drugs similar to stones cannot repair the damage of the body, and only nutrients can repair the damage. Selling drugs as nutrients will have adverse consequences. At present, about 20% of nutritional and health foods on the market are chemical substances. This kind of health food is impure in nature. Fake health food, just like a shemale is not a real woman, can be called a "shemale health product".
The third category: high-tech semi-synthesis, half of the raw materials are natural sources and half are chemical materials. For example, some multivitamin tablets, single dose, garlic essential oil, deep-sea fish oil and so on. Half of the raw materials are natural and half are chemical raw materials, so the effective non-nutritive substances have a weak effect, but their functions have lost their natural effects. When used, it is still used as medicine. At present, most of the health care products investigated by the management department are health care products with health care ingredients and drugs. The study found that the incidence of stroke and cardiovascular and cerebrovascular diseases increased by 33% compared with those who did not take such products. Commonly known as "health syndrome", that is, people who supplement nutritious health food have a phenomenon of "using and discarding", which makes them weaker and more prone to illness than those who do not supplement. This kind of health care products can be called "semi-shemale health care products".
The fourth category: high-tech technology puts forward natural and effective nutrients. This kind of health care product can be called "natural processed health care product". For example, some natural vitamin C, natural B vitamins, liquid calcium, lycopene, dietary fiber and so on. Made of natural fruits and vegetables, it meets the standards of non-toxicity and chemical composition, the only disadvantage is that it can not be used for a long time. The reason I mentioned earlier is that nature created human beings and gave them a comprehensive and systematic structure. At the same time, the food they eat is a comprehensive form of nutritional carriers, such as vegetables, apples, oranges, sweet potatoes and so on. They are all vitamins, carbohydrates, fats, minerals, water and so on. The history of human evolution of more than one million years shows that the human body is a nutrient body that adapts to comprehensive food rather than single recombination. In other words, the human body does not need single nutrients, but also non-nutrients and anti-nutrients. A single way to supplement vitamins or minerals actually has a negative impact on the human body. For the single nutrient supplement advertised in the current business, it must not be treated as a diet. Now, some cities have a "health syndrome", that is, people who supplement nutrients are more likely to suffer from cardiovascular and cerebrovascular diseases, indigestion and other diseases than those who do not supplement nutrients.
At present, the research on non-nutrients and anti-nutrients in plant foods is not in-depth and is still in the exploratory stage. It is still a dream to really produce organic and comprehensive nutrients. So:
(1) Vitamin supplements cannot replace vegetables and fruits. Vitamin health food is artificially made. Although the raw materials are natural, natural food is a natural ingredient in a certain proportion and has different properties.
(2) Natural food is produced according to a certain proportion, containing various vitamins, in addition to carbohydrates, protein, minerals, dietary fiber and other nutrients, which are organically combined, far from being comparable to single or compound artificial vitamins.
(3) The advantages of natural food are incomparable to any nutritional products. The organic combination of nutrients, non-nutrients and anti-nutrients in food, coupled with the result of * * *, can not be achieved by human science and technology at present.
(4) If the processed natural nutrients are used for a long time, it is likely that the organs will be "used in and discarded" and the genetic structure will be abnormal.
(5) There are not many vitamins in vegetables and fruits, so special people can supplement them reasonably. If you have vascular problems caused by vitamin C deficiency, you can supplement vitamin C. Therefore, although this kind of nutrition comes from natural food, I still suggest that you should not eat it instead of ordinary food, and you can supplement it at a certain stage when necessary. At the same time, I object to some people pretending to be nutrition consultants, encouraging consumers to eat a lot of nutritious and healthy foods, and even replacing diets at will, which is contrary to the laws of human body structure.
The fifth category: high-tech production, raw materials from natural plants, with a long history of use. For this kind of health food, the classification is very complicated. Many people don't list it as a health care product at all, because its composition and structure are very complicated. For example, components can be detected, and some are not detected by current technology. I came across these health foods and found that they all contain nutrients, non-nutrients and anti-nutrients Nutrients include carbohydrates, unsaturated fats, amino acids, minerals, vitamins and water. Non-nutrients include saponins, polysaccharides, phenolic acids, triterpenoid saponins, catechins, flavonoids and so on. Anti-nutrients include copper and zinc, phosphorus and calcium, phytoestrogens and so on. From the analysis of components that can be detected at present, from the point of view of nutrients, you will find many nonconformities, but this does not affect their obvious effects on human health.
The comprehensive effects of these complex components are still under study. It is estimated that their structures may have ester membrane structure, which is the fifth material structure in the world (that is, structures other than solid, liquid, gas and crystal structure) first proposed by scholars in Taiwan Province Province, China in 2004. At the same time, the plants mixed in the raw materials may achieve the harmless effect of the five poisons according to the principle of mutual generation and mutual grams of Chinese herbal medicines. Because it is a health food used by ancestors, the clinical effect does not conform to the viewpoint of western medicine, but this does not affect their good effect on health at all. However, we should pay special attention to the difference between them and the current health care products with clear nutritional components. This kind of health food can be called "historical health care product". Perhaps the theory of modern Chinese medicine is needed to reveal their mystery.
Through the above classification, we can clearly see that modern health food has developed from rough naturalization to artificial synthesis, from artificial synthesis to semi-synthetic and semi-natural combination, and finally to the stage of rational return to nature. Although it finally returned to nature, human understanding of its own healthy food has made a big step forward.
However, with the development of gene technology and biochemical technology, only the preparation method of health food has changed, and the structural form of food cannot change essentially. At present, the dosage forms are solid, liquid, gas, crystal structure and other forms; With the discovery of the fifth material form-ester membrane structure, new principle explanation and new production methods will appear in health food.
So, have you ever bought health food?
Is it "robber type" or "half-shemale type" if you buy it?
After all, there are not many professionals. I hope you can avoid blindly buying inferior health food and avoid harm.
Fourth, why do people doubt health care products?
However, when you want to buy health care products to supplement nutrition, you are confused again, because there are many health care products in China. To paraphrase: how bold people are, the health food market will be chaotic.
Of course, people in China need money very much, and many people need money to the extent that "I only have money in my eyes". Not many people think that there are other ways to show people's value besides money. Because of its special effect on health, health food has quickly become a carrier for a group of fake doctors, fake nutritionists, bragging elites and guys who study human weaknesses to play money games with each other.
The confusion of China's health food market is closely related to people's loss of health guidance.
First of all, people simply don't understand the way of life in developed countries. China media often do not report the real situation of developed countries, but instead add fuel to the fire and distort their lifestyles, making people mistakenly think that developed countries are what the media say, and learn to imitate and emulate them. For example, in fact, the United States is most opposed to high-fat and high-calorie foods, but we strongly advocate the eating habits of American steaks and hamburgers. Americans consume a lot of oil in cars. It has brought many disastrous behavior results to the environment, but we strongly advocate the luxury of owning a famous car. Americans have abandoned the abandoned chemical health care products, but we regard it as a symbol of identity and so on.
In addition, because many journalists in China media have no basic knowledge of nutrition, they misinterpret and mislead health food.
The third is that the health food management institutions in some places are overstaffed and have to deal with things, which leads to a word "chaos" in the health food market.
Health food first reflects the confusion of production.
Wait a minute.
