“The time has come to seriously ask whether antioxidant use more likely causes than prevents cancer,” Dr. Watson said. Nutritional intervention trials have shown no obvious effectiveness in preventing cancer or in lengthening lifespan, and, “in fact, they seem to slightly shorten the lives of those who take them.”
In long-awaited and landmark study published yesterday in Genetics, Lapham and 28 other authors collaborated to report telomere length in a cohort of Kaiser patients who gave saliva samples.
In this 2008 study of twins, British researchers looked at 52 pairs of identical and 15 pairs of fraternal twins and concluded that exercise, even after controlling for confounding variables of age, BMI, smoking, year of sampling, and socioeconomic status, was associated with telomere length preservation. The effect was 6 years of length for 100 minutes a week and 9 years of advantage for 3 hrs or more.
A youthful body and spirit are like a car with its lights on. It makes you visible and it makes everything around you brighter. A driver who has lost integration with his or her own environment and is merely preoccupied with what they see and whether it is enough to get them to their next stop may encounter problems that they never saw coming.
For #ScienceSunday, we turn to a recent article published online showing that a modified mRNA version of the telomerase protein (TERT) can extend the telomeres in a dose-dependent fashion. This method has the advantage of not being permanent, as with gene therapy.
