Keys to Long Life Found on Tiny Greek Island

Experts appear to have found the secret to longevity and it resides in the small Aegean island of Ikaria: siestas (short naps), a healthy diet, and oh yeah, genetics.

Conducted by Greek cardiologists, a study examined more than 1,400 residents of Ikaria (there is just a population of 8,000) over several months in 2009. Thirteen percent of those polled were over 80 years old and more than one percent were over 90.

“While in the rest of Europe only 0.1 percent of the population is over 90 years old, in Ikaria the figure is tenfold, 1.1 percent,” said Christina Chrysohoou, a cardiologist at the Athens university school of medicine.

Skinny Gene May Mask Bad Health

People who seem to eat what they want, when they want, and still stay thin are the bane of many people’s existence who struggle with weight (or at least they are responsible for some mild resentment). However, just because you’re skinny doesn’t mean you’re healthy.

Scientists are now sending out a warning to thin people that being lean doesn’t mean you can be carefree with your health. The concern centers around a so-called “lean gene.” This gene keeps people slim but also masks signs of heart disease and diabetes, particularly in men.

What the gene does is reduce levels of fat under the skin. However, what’s left is dangerous tissue that surrounds the heart and other organs.

“We’ve uncovered a truly fascinating genetic story and, when we found the effect of this gene, we were very intrigued by the unexpected finding,” said Professor Douglas Kiel of the Harvard Medical School.

Exercise Trumps Fat Genes

One of the biggest bummers in the struggle to lose weight is being genetically predisposed to obesity. But, according to new research, genes aren’t a dietary death sentence.

A British study, led by Dr. Ruth Loos of the Medical Research Council Epidemiology Unit in Cambridge, U.K., examined over 20,000 people between 39 to 79 years old. They focused on 12 genetic variants that are known to increase the risk of obesity. From there, they calculated a “genetic obesity-predisposition score” for each person.

Those in the study who were part of the active group – those who got more than an hour of daily exercise – reduced their genetic risk of obesity by 40 percent as compared to those who were inactive.
