Why Starving Cells Prolong Life

ScienceDaily (Oct. 14, 2008) — Cellular damage due to stress is an important factor in ageing processes. It is, thus, amazing that starving, which is a stress factor per se, decelerates ageing processes and extends the lifespan of organisms. It has long been known that proteins from the sirtuin family contribute to this mechanism. To date, the exact function of the seven members of the sirtuin family in mammals has, however, not yet been clarified.
