Aging is a natural phenomenon that includes metabolic changes which manifest as physical changes. The physiological processes that have been working hard to keep the bones strong, skin supple and body agile hardly works. The food that has been providing all essential ingredients for a healthy life now seems to be drab. In such a scenario, external supplements are necessary to either delay or cover up aging signs.

With increasing age, body synthesizes the necessary substances that keep the body healthy and young. As a result, skin loosens, dries, and wrinkles become visible. Food supplements have been considered beneficial, while the efficiency is still debated. Of such supplements, antioxidants are regarded as anti-aging agents. Antioxidants are molecules which can slow down oxidation or biological combustion. Antioxidants actually substances found in our foods. The cells utilize oxygen and produce free radicals as by products. These free radicals are the culprits for the damage.

Of the natural antioxidants, vitamin E, vitamin C and vitamin A are significant free radical busters. Apart from these vitamins, selenium, which is abundant in fish, red meat, eggs and chicken, is also a remarkable antioxidant.

Phytochemicals (plant originated substances) such as flavonoids/polyphenols found in red wine, grapes, tea; lycopene found in tomato and watermelon; lutein found in dark green vegetables are also effective antioxidants.

So, inclusion of natural sources of all these substances in food is generally sufficient to fight aging problems. But due to certain reasons, supplementary supply becomes necessary. Today, there are innumerable anti aging food supplements available. For instance, green tea, which is promoted as the manna for delaying aging and also slimming, is available in several varieties.

Although anti oxidant substances are beneficial, everything labelled ‘natural’ may not be all that natural. Caution and proper advice through physician or dietician is warranted for a healthy anti aging.
