Sciencedaily: Caloric Restriction Has a Protective Effect On Chromosomes

"We see that mice that undergo caloric restriction show a lower telomere shortening rate than those fed with a normal diet," says Blasco. "These mice therefore have longer telomeres as adults, as well as lower rates of chromosome anomalies," she adds.

"We believe that such a significant increase in longevity is due to the protective effect against cancer produced by caloric restriction -- incidents fall by 40% if we compare them with the mice that produce more telomerase and have a normal diet -- and, added to the presence of longer telomeres, this makes the mice live longer and better," says Blasco.

As I am still slightly disappointed by the NIA-study and lack of response by Michael I just want to weight in: the study shows that CR protects telomeres to some extend in mice. Whether this is applicable to humans and has any longvity effects in long lived mammals remains to be seen.

Scientists will know more about how calorie restriction impacts human chromosomes within a few decades. We should have something definitive within the next 100 years.
