You can't tell whether it's good for you or not. You can't tell whether it's food or medicine.
It has gradually become the best choice for people to give gifts, and many elderly people love it so much that they are willing to spend a high price to buy it continuously...
It is what has been hidden under the veil -- health care.
In the eyes of the Chinese, the definition of health care products is not clear and the types are very complex.
Usually, a drug that has not been clinically tested but claims to be beneficial to health or even to prevent disease.
In the United States, people refer to "immunity herbs," nutrients, vitamins, etc., as a form of medical deception.
Even so, the health care product industry is developing very quickly, and it has become a huge industry in a short time.
But in recent days, as the Spring Festival health care products are widely favored by people, the problems caused by it also quickly surfaced.
Both Chinese and foreign media have exposed some health care products in name only:
People's Daily: cure "pit old" health care product trap
Sina Finance: At present, all health care products in China are deceptive, no exception
Health: 14 Common Health Products You Don't Need
Alden: Don't waste money on health supplements
Therefore, even influential publications such as People's Daily and Health are reporting that Health care products are useless. What is the reason?
The market is highly respected gelatin, bird's nest, fish oil, protein powder these products, in the end how effective?
In fact, what they really look like...
The ejiao that is praised to the sky
Ejiao, which is simply "boiled donkey skin", can sell out donkey skin, Ejiao can be said to be unique.
Many people say that ejiao has great effect, it can cure diseases and heal the body if it is not sick.
Legend has it that when Cao Zhi was banished to Dong 'e, he was gauntlet and bloodless. It was because of the gelatin he ate that his face became rosy and shiny.
It is also recorded in the Addendum to the Complete Tang Poems · Palace Ci:
"The lead Chinese wash according to the abundance, rain drops lotus leaf beads difficult to stop. She refused to say that she was born to be a gentleman."
Yang Guifei beauty, but also adhere to secretly take the reason of gelatin...
Therefore, it is widely said that E-Jiao has magical effects, such as:
Improve hematopoietic function, inhibit tumor, regulate cancer cells, improve immunity, protect bone marrow, dilate blood vessels, promote calcium absorption, resist fatigue and hypoxia, improve clinical pregnancy rate, promote bone healing, maintain microecological balance of the body.
This set of the old directly made up flicker of the world around ah!
Since it is so powerful, why has ejiao never appeared in the famous prescriptions of Chinese medicine (Siwu soup, Bazhen soup, Shengyu soup, etc.)?
Because everyone knows, boil donkey skin can cure what disease? !
After modern medical analysis, protein in E-Jiao accounts for 60% to 85% and contains 7 kinds of amino acids essential to human body.
However! Donkey gelatin contains a kind of inferior protein!
Indeed, the food industry in most countries uses it only as an additive.
This kind of ejiao, which is made by boiling donkey skin, can be obtained by boiling pig, sheep or cow skin, which also has collagen.
Some people say, aren't there seven other essential amino acids? !
Yes, but a one-dollar egg contains all eight essential amino acids.
A piece of fat meat and an egg cost less than two yuan, and the effect is the same as that of gelatin.
Now, will you still go to buy the price of flying gelatin?
The bird's nest that blinded the Chinese
Bird's nest originated from the south coast of China and Indonesia, Malaysia and other places in Southeast Asia. It can be traced back to the Ming Dynasty. Legend has something to do with Zheng He.
So, how is a bird's nest made?
A bird's nest is made of the saliva of swifts and canaries, plus feathers and other material. What we eat is their nest.
Dried bird's nest contains about 50% protein, 30% carbohydrates, 10% water and some minerals. In addition, it contains sialic acid, epidermal growth factor, and colony stimulating factor. It is said to have the effect of nourishing Yin, moistening dryness, replenishing qi and treating deficiency.
Sounds awesome, right? Big to fill?
Let's see what the facts are...
First, the canary feeds mainly on insects, and what it vomits out is its own saliva, not undigested food. Eating bird's nest is... Eat the saliva!
Then, bird's nest is high in protein. How high?
It was almost higher than the skin of tofu and pig!
Moreover, the amino acids contained in bird's nest are not essential for the human body,
So the study says:
"Bird's nest contains some poor quality protein, single function. In terms of nutritional value, bird's nest is just a low-grade food with limited nutrition."
But you know what?
In nature, there is no way to control the quality of these substances in the bird's nest.
There have even been cases of bird's nests exported to China from Singapore and Indonesia containing heavy metals, which may cause food poisoning instead of nutrition!
When it comes to sialic acid, epidermal growth factor and colony stimulating factor, it's even more ridiculous.
Sialic acid is saliva that carries cells around the body.
If cancer patients eat bird's nest, the consequences...
Epidermal growth factor. Sounds like it can change the skin?
This is actually a substance that is used for targeted therapy, and there is no literature showing that it can regenerate the epidermis.
colony Stimulating Factor, this is really awesome, really awesome. But people can only rely on injection to produce the effect, has anyone injected bird's nest...
So, bird's nest is the same as Cordyceps, just "scarce is valuable", don't waste money...
Protein powder that healthy people do not need
Some people are too fat to extricate themselves, while others are so skinny that they are skin and bone.
As a result, some businesses will jump out:
Too thin people to supplement protein! Otherwise you'll stay so thin! Eat also eat not fat!
So, this enviable crowd started buying protein powder like crazy...
So, is this really the case?
Protein powders, like milk powder and meat, contain both protein and protein
There is no difference in protein in eggs, but it is abundant, as low as 50% or more.
But how are humans supposed to absorb so much protein? !
Healthy adults need about 1 gram of protein per kilogram of body weight per day, which is an amount that can be completely satisfied by eating a normal diet.
Therefore, healthy people on a normal diet do not need additional protein and cannot absorb too much protein!
In addition, the energy of our usual activities and the improvement of immunity all depend on the role of protein. If the human body lacks protein, it will bring great harm to health.
So, if there was a real protein shortage, the person would probably already be in a hospital bed. Therefore, healthy people are not necessary to use protein powder to supplement the body protein, so usually fitness people? Not necessarily.
You don't need to take protein powder until you've reached a certain intensity!
In fact, muscle is not grown in the gym, machine training will only destroy muscle fiber, and protein powder, is used to replace the damaged muscle. So, if you're not training hard enough to destroy muscle fiber again, you don't need protein powder at all.
Fish oil is largely ineffective
If you live in Australia, you must have the same feeling. Every time you return to China, your relatives and friends come to ask for some health care products. Among them, fish oil is the most popular one.
Fish oil is the third most widely used dietary supplement in the United States and Australia, after vitamins and minerals.
At least 10 percent of the population takes fish oil regularly, and most of them believe that the omega-3 fatty acids in fish oil promote cardiovascular health and reduce the risk of heart attacks.
Omega-3 fatty acids reduce inflammation and thin the blood, which reduces the risk of blood clots.
Fish oil, as the name suggests, is derived from fish. So, is it better to eat fish oil or fish?
Seriously, of course eating fish works...
The National Institutes of Health reports that
Most clinical trials of fish oil have found no evidence that it reduces the risk of heart attacks and strokes.
At least two dozen rigorous studies of fish oil were published in top medical journals between 2005 and 2012, but almost all of them failed to show a clinical effect. Instead, they proved that omega-3 fatty acids do not translate well into benefits in the body.
According to the journal JAMA Internal Medicine in 2014:
"Despite more and more tests showing that [fish oil] doesn't work, sales are going up."
Dr. James Stein, director of preventive cardiology at the University of Wisconsin Hospital and Clinics, has run experimental and clinical studies on fish oil and hasn't been able to find benefits either.
In The New England Journal of Medicine he had this to say:
A clinical trial of 12,000 people found that taking one gram of fish oil a day did not reduce deaths from heart attacks or strokes in people with evidence of atherosclerosis.
Which is a bit of an embarrassment for scientists working on fish oil...
The health care products have been well known
In addition to the above "let a person misunderstand" health care products, there are some of our life familiar with the "magic medicine", in fact, there is no too significant effect on health.
The healthiest things you can do are eating right, living a regular life, and exercising. Nothing can reverse nature. No matter how many health care products you eat, you can't resist "survival of the fittest".
In addition to the health care products mentioned above, there are also the following kinds of food to be named and criticized by the People's Daily.
Grape Seed: Escaping Concepts
Usually spit out grape seeds, is also advertised as anti-cancer, anti-oxidation, anti-aging, a variety of "grape seed oil", "grape seed powder" is also selling hot.
There is a lot of data on the inhibitory effect of grape seed extract on cancer cells, but the premise of the conclusion is clear - "in vitro inhibitory effect on cancer cells."
"In vitro studies" can only indicate that specific cancer cells can be further studied, and there is no evidence that grape seed extract can inhibit cancer cells in vivo.
Organic food: psychological comfort
Every time you go to the supermarket, someone will always sell you all kinds of "green vegetables" and "organic rice", which sounds very high-end and healthy!
But is this really the case?
In fact, expensive, does not equal to good.
Earlier, the consumer association had conducted sampling inspections on organic food and green vegetables on the market, testing pesticide residues, heavy metal pollutant limits and physical and chemical indicators respectively.
The test results are surprising, these so-called "organic food", "green vegetables", although the price is much higher than ordinary vegetables, but these indicators are still beyond the national standard test results... A hard hit in the face...
Sea Cucumber: No better than an egg
Now as long as you go to some of the restaurant to attract customers, the boss immediately began to promote their own home sea cucumber! It's got a lot of protein in it, and it's got to be good and healthy.
However, it is very expensive. Are sea cucumbers really so magical?
The value of sea cucumber is protein, but it is high in protein, but not high in quality. Protein is of high quality and low quality, and its quality is mainly judged by the absorption rate of amino acids in protein.
Antidote: does not reduce the harm of alcohol intoxication
As long as the old editor returned to China, the domestic partners lined up to find me to buy antialcohol medicine. All kinds of antialcoholism medicine in the drugstore are selling fervently, and they also claim that they can not get drunk by a thousand cups. Actually, more than that, it just gives people a reason to drink more...
The cure is a gimmick. Their batch number is not medicine, but health food.
Their ingredients are just some liver protection ingredients, and can not reduce the harm of drunkenness.
The key to hangover is to drink in moderation. Drink no more than 2 taels of liquor and no more than two bottles of beer a day.
Enzyme: Inactivated as soon as it enters the mouth
Enzyme nearly two years of fire is not good, many businesses have claimed that this goods can help detoxification beauty lose weight, the same speed as God crowded into the health care list.
But, lazy people ah, you are fat, no action, no willpower to lose weight?
"Enzyme diet" is a complete fudge. "Enzyme" is actually the Japanese name, which is what we are familiar with "enzyme".
The stomach is very acidic, and enzymes in general have a hard time surviving in such an environment. once the enzyme enters the stomach, be decomposed immediately, ate equal to eat for nothing...
Black sugar: just grow black
Girls during menstrual period love to eat black sugar, black sugar food began to become a lot of people like snacks, has been declared as a natural health food, has the role of beauty and health.
In fact,... It's brown sugar...
"Dark sugar is what we call brown sugar, and it works just as well as regular brown sugar."
Many people think that dark sugar works better than other sugars, but it doesn't. Both brown and brown sugar are sucrose, which are essentially the same and have the same nutritional value and edible efficacy.
Black wolfberry: It's better to eat eggplant
Black wolfberry was once called "soft gold", according to the business propaganda has the all-purpose effect, the price up to thousands of yuan per kilogram, and even triggered thousands of people to steal wild black wolfberry.
Ah... All the aubergines in this world are robbed...
Goji berries are just a little bit higher in anthocyanins than goji berries.
Actually, daily purple black food, for example grape, eggplant, purple sweet potato, mulberry contains anthocyanin, want to use black wolfberry to supplement, cost performance is very low.
Propolis: There is no scientific basis yet
Propolis is said to protect against foreign invaders such as bacteria.
Ancient people in Greece, Rome, Egypt and other places used it to heal wounds, inflammation, and mummy. So, does it have the same effect on people?
