No doubt, everybody wants to longer their potential youth as long as possible. Recognize and accept the aging process and all that goes with it as a reality, a natural part of the life cycle; it happens to us all. We fear and deny aging, the nutritionists emphasize, because we fear and deny death. "In our denial of death and the aging of the body, we have rejected the wisdom of the aged, and in doing so have robbed old age of its meaning and youth of its direction," Rechtschaffen asserts. We pretend that old age can be turned into a kind of endless middle age, thereby giving young people a false road map to the future, one that does not show them how to plan for their whole life, gain insight into themselves, or to develop spiritually.

The signs of denial and anxiety over aging permeate every aspect of our lives. We have no role models for growing old gracefully, only for postponing it. Just as our fear of memory loss can create actual memory decline, the dread of aging may be taking its toll on many other body systems. In these respect, at first, we have to discuss about the background of the youth & the antonym aging process.
In the several studies, it is proved that the free radical is the main culprit in this area. So, we have to know what free radical is.

Free Radical:

Free radicals are naturally produced in the body through the normal metabolism of amino acids & fats. Oxidative damage is caused by highly reactive oxygen ions (free radicals) that circulate in the blood and get into every body tissue, including the eye lenses. These free radicals are unstable molecule that can freely react with & destroy healthy cells. The main target of free radicals is the damaging of nucleic acids, proteins or lipids. For this reason, they can damage the cell membrane & DNA through a process known as oxidative stress, are blamed for many of the dysfunction & disease associated with aging. Of course, oxygen is necessary for life, but just as oxygen rusts iron, free radicals damage the body. Some free radicals occur naturally, but lifestyle choices greatly affect the number in your body. Free radical also damage to LDL cholesterol leads to atherosclerosis, so antioxidants have the potential to protect against cardiovascular disease.

Antioxidant:

Antioxidants are molecules that can neutralize free radicals by accepting or donating an electron to eliminate the unpaired condition. Typically this means that the antioxidant molecule becomes a free radical in the process of neutralizing a free radical molecule to a non-free-radical molecule.

Antioxidants act as "free radical scavengers" and hence prevent and repair damage done by these free radicals. Smoking and a high-fat diet greatly increase free radicals, while fruits and vegetables--which are rich in antioxidant vitamins and minerals--eliminate them and minimize the damage they cause.
Antioxidants are found abundant in beans, grain products, fruits and vegetables. Look for fruits with bright color - lutein in some of the yellow pigments found in corn; orange in cantaloupe, butternut squash and mango; red from lycopene in tomatoes and watermelon, and purple and blue in berries. So enjoy eating a variety of these products. It is best to obtain these antioxidants from foods instead of supplements. In addition, minimize the exposure of oxidative stress such as smoking and sunburn.
Recently, It has been projected that, eating certain berries and vegetables on a regular basis may keep you from age-related memory problems down the road.

So, on the basis of above discussion, you can agree with me that, why we don’t utilize the opportunity which ensures a better and healthier aging.
