Can calorie restricted diet enhance the life span of humans?

 Researches from united states and china have conducted the experiment on rats,monkeys,rodents. They have observed that when they have treated these animals with calorie restricted diet it has created a anti ageing characters in these animals.

“The effect of caloric restriction on extending healthspan and lifespan suggests that aging is reversible and druggable,” co-author Guang-hui lui  a professor at the Chinese Academy of Sciences.

“We hope that we can identify the intervention target to mimic the beneficial effect of caloric restriction in the future.”

Researchers pitted two groups of rats against one another: One group received 30 percent fewer calories versus the other group, who were kept on a normal diet. The researchers followed the rats over the course of nine months, from age 18 months (middle-aged for a rat) to 27 months, deliberately choosing older rats as this is when potential clinical applications would prove most effective. The rats’ ages were comparable in humans to about the ages 50 through 70.

They found that the rats who were subjected to calorie restriction didn’t display almost 60 percent of the age-related changes in cell composition that occurred in the rats on a normal diet.

Older rats on a calorie-restricted diet were also found to share similarities in tissue and cell composition with young rats on a normal diet, suggesting that older rats maintained similar physiology to rats much their junior.
