Antioxidant activity of Fuding White Tea
With the improvement of people's living standards, people pay more and more attention to health. The word "antioxidant" is mentioned frequently, but do you really know about it?
The essence of the so-called antioxidant is to scavenge free radicals in the body. Free radicals are constantly produced in the human body due to continuous contact with the outside world, including respiration (oxidation), external pollution, radiation and other factors.
Smoking, air pollution, water pollution, radiation, pesticides, high stress in life, excessive exercise, and so on, can increase the concentration of free radicals, which is called oxidative stress. The greater the oxidation pressure, the higher the concentration of free radicals in the body.
The body's antioxidants are not only self-synthesized, but also supplied by food. However, with the development of society, there are more and more factors that increase the concentration of free radicals in daily life, and their own antioxidant system is facing the crisis of underuse. At this time, we usually need to rely on outside food to provide antioxidants.
The importance of antioxidation
More and more studies have shown that antioxidation is an important step in preventing aging and many health problems. If excessive oxidative free radicals can be eliminated, many diseases caused by free radicals and aging-related diseases can be prevented.
