"Shen Nong's Food Classic" once recorded that "regular food is powerful and pleasant", and "Za Lu" also recorded that "bitter tea lightens the body".Through observation and practice, the ancient Chinese people knew that tea was beneficial to human health. With the deepening of people's understanding of the tea, its anti-aging effect has been widely recognized.
So, how does tea drinking tea fight aging?
It starts with the free radicals. Free radicals are atomic or molecular groups with asymmetric electrons, such as hydrogen radicals, superoxide ion radicals, hydroxyl radicals, peroxide hydroxyl radicals, organic radicals, and so on. These are some very active, highly reactive particles, in addition to food, drugs in the body, radiation, high temperature or environmental abnormal factors can also induce the formation of free radicals. Human growth and metabolism is dominated by genetic factors, but it is also affected by some internal and external substances. Thus, these substances produce free radicals in the human body.
The harm that free radicals cause to the human body is enormous. It can cause deoxyribonucleic acid (DNA) destruction, thus promoting intellectual decline, muscle atrophy, premature aging phenomenon; can also to human protein oxidation damage, and can oxidation in the body of unsaturated fatty acids, make fat deterioration, causing cell membrane, mitochondrial membrane, enzyme membrane sclerosis, arteriosclerosis. It seems that free radicals are the main culprit of accelerating human aging.
Even so, free radicals are not scary. It harms the human body, and the human body also has the instinct to clear and defend. The human body can produce body enzymes to remove free radicals in the hydrolysis reaction, people's diet is often inhaled antioxidants, alleviate the harm of free radicals, so usually oral some non-enzymatic Vitamin C and Vitamin E are very good for the human body, and tea contains these nutrients.
In addition to higher levels of vitamin C and vitamins, tea also contains beneficial catechin compounds. Catechin compounds have strong antioxidant properties, which can play a good anti-aging, life prolonging effect. In addition, the tea polyphenols contained in tea also have strong antioxidant and physiological activity, it is the scavenger of human free radicals, can effectively block lipid peroxidation reaction, remove active enzymes, anti-aging effect is 18 times stronger than Vitamin E.
In today's life, drinking tea is not only a content to improve the diet structure, but also has a strong antioxidant activity effect, and the role of delaying aging has been recognized by more and more people.
