All substances, organisms, and plants on the earth are undergoing oxidation reactions all the time, which is a natural factor created by the evolution of life, all objects have origins and must die, the universe is circulating, there is no eternal evolution, and people are certainly no exception; Relying only on natural evolution, people can not get rid of the erosion of free radicals, can only be artificially controlled, the current technology can not achieve complete inhibition of free radicals in the human body, can only be controlled by drugs, diet, etc., and there is no authoritative scientific basis for its efficacy. According to the current research theory of free radicals, if free radicals disappear in the human body, there will be no adverse reactions, and the human body will greatly increase its survival probability close to the end of life, but there are many other factors that accelerate the pace of human aging.

Free radicals are the product of oxidative reactions, so if you lose free radicals completely, there will be no oxidation reaction, including the most important respiration, so the human body will naturally die.

The normal total blood volume of an adult is about 7%-8%, for example, a person weighing 60 kg has a total blood volume of about 4200-4800 ml.
When the amount of bleeding is less than 400 ml, nothing will happen, when the amount of bleeding is 800 ml - 1000 ml, there will be some uncomfortable symptoms, and when the amount of bleeding is more than 1200 ml, life is at risk.

Free radicals are the most important organic groups in the oxidation reaction of the living body, which can make various tissues and organs be oxidized, metabolism is blocked, the body's function declines, and eventually leads to life failure. Although too many free radicals are harmful to the living body, the living body is all redox reactions, material transportation, energy conversion, signal transduction, and all metabolic activities rely on the oxidation reaction function of free radicals to a certain extent, so if the free radicals disappear, people will also die.

If the electrons of the cell protein molecule are deprived, the protein will be connected to the branch chain and alkylated, forming a distorted molecule and causing cancer. Due to its own lack of electrons, the distorted molecule has to seize the electrons of neighboring molecules, which in turn causes neighboring molecules to also undergo distortion and cause cancer. The snatching of electrons in somatic cells is the root of all diseases, and free radical ROS is a substance that lacks electrons (unsaturated electronic substances).
Genetic mutations lead to the formation of a large number of cancer cells, and finally cancer. And when free radicals or aberrant molecules rob the electrons of genes, people will directly get cancer. After the human body gets negative ions, because the negative ions are negatively charged, they have extra electrons, which can provide a large number of electrons, and block the vicious circle, and cancer cells can be prevented or inhibited.
Hazard Mitigation Methods:
Studies have shown that the process of free radicals from generation to decay is the process of electron transfer. In living systems, the transfer of electrons is a basic movement, and oxygen has a strong ability to gain electrons.
As a result, many chemical reactions in living organisms are related to oxygen. Scientists have found that almost all free radicals that damage human health are related to those more reactive oxygen-containing substances, and they call the free radicals that bind to these substances reactive oxygen radicals. The damage to the human body caused by reactive oxygen radicals is actually an oxidative process.
Therefore, to reduce free radical damage, it is necessary to start with antioxidants.

Damage to the human body by free radicals:1. Weaken the resistance of cells and make the body susceptible to bacterial and bacterial infections.
2. Produce chemicals that destroy cells and form carcinogens.
3. Hinder the normal development of cells, interfere with their recovery function, and make the cell renewal rate lower than the wilting rate.
4. Destroy the genetic (DNA) tissue in the body, disrupt the operation and regeneration function of cells, cause gene mutations, and evolve into cancer.
5. Mitochondria in cells, causing oxidative fatigue.
6. Destroy the cell membrane, interfere with the metabolism of the cell, and make the cell membrane lose its function of protecting the cell.
Negative ion scavenging method.
Negative ions can reduce excess reactive oxygen species in the body, which can inhibit the oxidation of living organisms. Negative ions can increase the uptake rate of vitamins, amino acids, and minerals, and the decomposition of vitamins can eliminate reactive oxygen species and improve the activity of anti-free radical substances.
Anti-free radical scavenging method.
Superoxide dismutase, vitamin E, vitamin C, carotene, anthocyanins, flavonoids, polyphenols, catalase, glutathione peroxidase, reducing glutathione, selenium are all highly effective substances to fight free radicals.

Meaning of Free Radicals:
The human body itself has antioxidant capacity, which is an enzyme that can decompose free radicals, and the medical community calls it the "scavenger" of the human body. However, as we age, the enzyme activity in the body decreases, and eventually the body's antioxidant capacity is unable to remove the free radicals that have been accumulating.
Disadvantages: 1. Under the action of free radicals, collagen will react, so that **not enough nutrients**, resulting in **tissue vitality, loss of elasticity, wrinkles, aging of the whole body, dull complexion, etc.
2. With the increase of age and the increase of free radicals, the degree of corrosion of free radicals into protein cells and fat cells in the body is also deepening, and lipofuscin accumulates more and more, resulting in the slow formation and appearance of pigmentation.

Theoretically, any two different substances in contact with each other will produce free radicals, for human beings, whether in vivo or in vitro, free radicals are constantly increasing and being produced at an unprecedented rate, in general, the ** of free radicals has the following aspects.
Smoking (secondhand smoke), alcoholism, overeating, irregular lifestyle.
Free radicals are produced by radiation, ultraviolet rays, electromagnetic waves, sun exposure, or radiation to which cancer patients are exposed**.
Environmental pollution, including air pollution, drinking water pollution, industrial wastewater pollution, soil pollution, automobile engine exhaust, industrial exhaust gas, combustion of sulfur-containing inferior coal, and photochemical smog, etc.
Abuse of chemical drugs, such as food additives, pesticides, vegetable and fruit contamination, drugs, therapeutic drugs, etc.
Mental conditions, stress, impatience, anxiety, depression, nervousness, strenuous exercise, etc., can also produce free radicals.
Modern urbanites, life is stressful, the living environment is not good, full of all kinds of pollution, and free radicals are overflowing in the body, if.
If left unchecked, it can be relentlessly attacked by billions of free radicals every day.
Metabolism of tissue cells. Oxygen plays an important role in sustaining life, and people who lack oxygen will die within minutes. Oxygen is transported through the blood circulation to the whole body to meet the needs of cells, but at this time, about 2%-3% of oxygen is catalyzed to form oxygen radicals, which can be found everywhere in the human body, swim everywhere, active and aggressive, just like oxidation corrodes metals.
Ischemia after tissue and organ injury, such as myocardial infarction, cerebral thrombosis, trauma, etc.
Abnormal fermentation of the intestinal system. Abnormal fermentation of the intestinal system produces 90% of the body's free radicals.
A sip of alcohol produces 800,000 free radicals.
A puff of cigarette produces 1 million free radicals.
One use of low-quality cosmetics yields 1 million freedoms.
A single consumption of fried food produces 10 million free radicals.

Free radicals are mainly formed during normal biological activities such as respiration, but because ** is the main contact point between you and the outside world, external environmental factors such as ultraviolet radiation, air pollution, and cigarette smoke can also cause more free radicals to appear.
As we've said many times, daytime UV exposure is an important time for free radical production and one of the biggest skincare concerns: within 15 minutes of exposure to UV light, free radicals form and last up to an hour.

There are many foods that are high in potassium, and yellow-green fruits are high in potassium. Since potassium plays an important role in anti-cancer prevention, in addition to reducing sodium intake in the diet, eating more foods containing potassium will greatly reduce the probability of cancer. Fresh yellow-green vegetables and fruits, such as fresh dates, citrus, persimmons, apricots, kiwifruit, prickly pear, sea buckthorn, blackcurrant, etc., are rich in a large number of vitamins and essential trace elements. >>>More
