Sirtuins is becoming a trendy term in the sphere of skin care. Yet, in line with its popularity, some people do not really know what sirtuins are? It is, a class of proteins that exists in various organisms in humans, plants and even bacteria.
There have been several studies conducted on the field of calorie-restricted diets. The animal studies have shown that mammals, which are fed with calorie-restricted diets, are healthier and live longer than animals which are fed with a normal diet. This positive effect of calorie-restricted diets is unknown to high degree. However, sirtuins seems to have its role to play. Recent research has shown that sirtuins may slow down the aging process. It contributes to postpone cell death by safeguarding cells from “DNA damage”.
The calorie-restriction formula is yet fully proved for humans. It is highly possible that humans experienced an alternative effect compared to monkeys and fruit flies, on which the study has been carried out. Nevertheless, we are slightly progressing and understanding that starving is not the only way to initiate the benefit of sirtuins.
Sirtris, a research company has proved that resveratrol, is a particular antioxidant present in the skin of red grapes. This component activates sirtuins. It was shown in a research conducted on mice, that once they were put under high doses of resveratrol several health benefits were seen. It enhanced insulin resistance, assured weight control and augmented lifespan by around 20 percent. A mouse that was put on treadmill was miraculously able to run twice as fast and far than a mouse that had not been given resveratrol.
Truth Or Empty Promises
Nonetheless, it is certain that companies in the skin care sector are definitely eager to derive high profit from sirtuins. Companies such Avon have already launched products with the component, whereas other Spanish and German companies are also adopting the power of red-wine into their creams.
The promise of whether sirtuins will help to act as anti-aging substance will be seen after some years of use. It has already been shown that red wine and grape skin are vital antioxidants needed to assure longevity as well as healthiness. So, sirtuins can hopefully be significant weapon for anti-aging.
