Want to live longer? Scientists say they have to consume less sugar
Cynthia Kenyon, director of the Center for the Biology of Aging, University of California at San Francisco, is one of the defenders of that basic recipe after finding that giving only a small amount of sugar to worms with that experience leads to age faster and live less.
"That suggests very clearly that sugar reduces life expectancy," said Kenyon, who is since 2008 a diet low in carbohydrates, which probably explains its thinness visible.
The scientist described as "incredible" that many people, especially in America, does not know what is good to eat and said that the field of nutrition is increasingly respected among scientists in the coming decades.
DIET AND EXERCISE
Ana Maria Cuervo, a Spanish-born doctor who co-directs the Institute on Aging of the Albert Einstein College of Medicine in New York, and investigating how to repair the damage to cells over time, also believes that a healthy diet and exercise are crucial to delay aging.
"One of the main triggers cell cleaning system is the reduction of calories," said Crow, who added that glucose, in contrast, has a negative effect on that process.
Cleaning processes are up and running in all cells and are key to healthy cell function, but its effectiveness decreases with age, which is associated with neurodegenerative diseases that occur in the last stage of life.
So far, studies to try to extend this healthy process performed in mice, but Dr. Cuervo experiments are expected to begin soon in humans.
SCIENTIFIC ADVANCES
Aubrey de Grey, an expert in aging, focus their hopes in regenerative medicine. He explained that the human body is a machine and like a car could pass for a regular process of repair and overhaul to prolong an existence in good condition.
The data show that the aging is now a reality. So, Ted Fishman, author of a book on aging of the world population, said today that in 2000 there were 180,000 centenarians in the world. This year there are already 450,000 and is expected that by 2050 the number more than three million.
"We live magical moments," he said, referring to the possibility of extending the unusual gift that is life.
