How to Reduce the Harm of Free Radicals to the Human Body?

Free radicals exist objectively, for humans, free radicals are being produced at an unprecedented rate, both in and out of the body. The incidence of diseases associated with free radicals is also on the rise. Since humans can't escape the siege and clamping of free radicals, we can only find ways to reduce the harm of free radicals to us.

With the deepening of the study of free radicals by scientists, the methods of scavenging free radicals to reduce the harm of free radicals to human body have been gradually revealed.

Research shows that the process of free radicals from generation to decay is the process of electron transfer. In the life system, the transfer of electrons is a fundamental movement. Oxygen has a strong electron capacity, so many of the chemical reactions in organisms are related to oxygen. Scientists have found that free radicals that damage human health are almost all linked to more oxygen-containing substances, the free radicals that they combine with these substances are called reactive oxygen radicals. The damage of reactive oxygen radical to human body is actually an oxidation process. Therefore, to reduce the damage of free radicals, we must start from oxidation resistance.

Since free radicals exist not only in the human body, but also from the human body, then there are two ways to reduce the harm of free radicals: one is to remove excess free radicals from the body by using endogenous free radical scavenging system; The second is to explore the exogenous antioxidant -- free radical scavenger, which blocks free radical invasion of human body.

A large number of studies have shown that the body itself has the ability to remove excess free radicals. This is mainly based on the endogenous free radical scavenging system, it includes superoxide dismutase (SOD), catalase, glutathione peroxidase and other enzymes, and vitamin C, vitamin E, reduced glutathione, carotene and selenium antioxidant. Enzymes can make the active oxygen free radicals in the body become less reactive, thus weakening their ability to attack the body. he enzyme's defense is limited to fine cells, while antioxidants are found to have some effect on the cell membrane, and others can act as defenses outside the cell. These substances are deeply embedded in our bodies, and as long as they keep their weight and vitality, they will be able to remove the extra free radicals and keep the free radicals in our bodies in balance.

In order to reduce the harm of free radicals to the human body, in addition to relying on the free radical scavenging system of the body, we should also seek and explore exogenous free radical scavenger. We can use these substances as stand-ins to allow them to bind to free radicals before free radicals enter the body, and it can block attacks from free radicals and to protect the body from harm.

In nature, the range of antioxidants that can act on free radicals is wide and varied. At present, it has evolved from simple synthetic antioxidants and food oxidants to natural antioxidants and free radical scavenging agents. As a result, the demand for antioxidants is increasing, and the widely used synthetic antioxidants are increasingly rejected because of their potential toxicity and carcinogenic effects, therefore, the search for natural, efficient and low-toxicity antioxidants from plants has become an inevitable trend in the development of antioxidants. And the search for free radical scavenging agents from natural plants will also be the development trend of modern medicine and health industry. Many valuable natural antioxidants have been found at home and abroad. In this research, Chinese scientists have been at the forefront of the world. They have discovered and proved that some of China's unique edible and medicinal plants contain a large amount of phenolic substances, these substances are characterized by electrons that are easily taken away by free radicals, and they become a stable substance that does not harm humans when they lose electrons. From current research, natural plant antioxidants are mostly polyphenols, among them, tea polyphenols, grape seed extract and rosemary extract were used more.

Experts from the institute of biophysics of the Chinese academy of sciences have spent eight years developing natural antioxidants - free radical scavenging agents - from these plants. In the case of the acute toxicity of animals in cooperation with cigarette factory technicians, it proved that after using free radical scavenging, the life of the mice was significantly longer than that of mice without free radical scavenging. The longest can even lengthen nearly double the life span, and the cancer rate of the gene is greatly reduced. Of course, if human beings want to fundamentally avoid the violation of redundant free radicals, they should also improve their environmental consciousness and improve our living environment.
