相关文章Why Aging
Aging is the progressive accumulation of changes over time that increases the probability of disease and death. The principal damage theory, the free radical theory of aging, holds that the aging may be due to the cumulative consequences of free radical reactions.
Free radicals which are the by-product of every day cell metabolism for energy generation carries extremely high energy and is always inexorably searching for another electron every moment. They can damage normal tissues while too many of them are produced or not adequately controlled. Free radicals can injure biological molecules, such as DNA, proteins and lipids, causing cell and tissue damage leading to aging and disease. The prematurely aged, wrinkled skin of smokers is caused by the free radical-induced damage that smoking caused. In fact, smoking is probably the greatest source of voluntary exposure to free radicals.
Therefore, Most of us now live forty years less than the maximum human life span which is 110-120 years old, and often our later years are blighted by degenerative disease
How to slow down aging, live younger?
Most of us are taking antioxidants because we want to look and feel younger. This is not just wishful thinking. Maintaining the antioxidant advantage - that is, keeping free radicals in check - may be one of the most effective ways to slow down the aging process. While we can't stop the years from passing - or our bodies from growing older - we can use antioxidants to help minimize the damage inflicted by free radicals, thereby slowing down the process.
To aid in biodefense, a system of antioxidants exists to neutralize radicals after they have formed. Antioxidants (such as Vitamin C, Vitamin E, Co Q10, Lipoic Acid, and Flavonoids like Polyphenols, etc.) will directly react with peroxy radicals to destroy them and form inorganic or organic hydroperoxides.
