It is reasonable people were dreaming of eternal juvenility. They are trying to discover a charming philosophers’ stone of life that would contain, or at any rate check, the sorrowful gait of ages and coming senescence. And of a sudden you read: “Antioxidants – prevention against aging.” Honestly speaking, few people understand what senescence is from scientific viewpoint; as regards antioxidants or free radicals, these notions remain quite uncertain for many people.
What is senescence?
Aging is the accruement of alterations in the organism during lifetime. Corporal, intellectual, and social changes are found out when senescence. With time the potentiality to respond to stress is attenuated and the peril of affections is elevated. Still, men of science say that even with aging the supreme potential does in truth exist for high-energy, psychical, and social melioration. To tone up this potential, powerful antioxidants can become a sure reenforcement for bar against senescence. Caregivers discovered that middle-aged adult people who employ antioxidants as prevention against senescence are more fortunate at mastering their emotions and go through unfavourable feelings less often than younger grownups. Antioxidants as prevention against aging are able to result in successful senescence, which implies that the diseases occur less frequently, the perceptive and energetic powers are high, and older persons are actively involved in life.
Free radicals and senescence
It is recognized that oxygen is required for life. But at the same time, oxygen is an extremely reactive molecule and may hurt DNA, proteins and lipids by producing activated oxygen species in the living cells such as the hydrogen peroxide (H2O2), hypochlorous acid (HOCl), and free radicals – the hydroxyl radical (·OH) and the superoxide anion (O2?). The organisms contain a system of antioxidants to preclude the impairment to the living cells.
The free-radical hypothesis of aging confirms that organisms grow old because molecules, cells, tissues and organs collect free radical harm. From this viewpoint, the antioxidants could be considered as a good prevention against aging. The free radical theory addresses not merely senescence, but as well age related sufferings. The hurt to the collagen results in vessel rigidity, thickening, high blood pressure and atherosclerosis. The corresponding processes in the kidney can result in nephritic failure. Lipide peroxidation of the mitochondrial membranes destroys the electrical potential and the ability to generate energy.
Can antioxidants be utilized for cure and prevention against senescence?
Antioxidants stop the molecular oxidation by removing free radicals. Plants and animals possess arrangements of antioxidants, such as vitamins C, A, and E. The antioxidants react with oxidizers in the living cells, protecting cell membranes from lipid peroxidation. This is the ground why numerous physicians think that antioxidants are the actual and efficient prevention against aging. People who consume fruits and vegetables, that contain antioxidants, have a reduced risk of age corresponding sufferings. Antioxidants are as well prescribed as ingredients in dietary supplements for skin age maintenance and prophylaxis sicknesses.
As well every last elderly person should know about diabetes as at respectable age this sickness can severely complicate a life.
