Starvation can trigger longer life
Thursday March 03 2005
Scientists are closer to understanding how starvation can, paradoxically, extend lifespan.
In a paper published today in Nature, Pere Puigserver, of Johns Hopkins University School of Medicine, showed that a gene linked to ageing in mice is switched on during starvation to maintain a balanced level of glucose in the animal's blood.
"Caloric restriction causes many changes in glucose metabolism and extends lifespan; however, how this metabolism is connected to the ageing process is largely unknown," it said.
Puigserver's team studied a mammal protein, SIRT1. The equivalent version in yeast and worms is known to delay ageing when food intake is severely restricted.
The research showed that fasting triggers production of SIRT1 in the liver of mice. This starts a chain reaction leading to the eventual production of glucose in the blood. This keeps the animal alive while also delaying ageing.

Thank you Brother Jamal. Hence, the Truth about fasting has become clearer to us.
