Eating Less May Prevent Aging In The HeartTopics: Medical Science News
According to researchers, eating a very low-calorie yet nutritionally balanced diet is good for your heart.
Investigators at Washington University School of Medicine in St. Louis studied the heart function in members of an organization called the Caloric Restriction Society, and found that their hearts functioned like like the hearts of much younger people.
And the finding is backed up diagnostically with ultrasound examinations, which showed that the hearts of people on caloric restriction appeared more elastic than those of age- and gender-matched control subjects. Their hearts were able to relax between beats in a way similar to the hearts in younger people.
According to the principal investigator Luigi Fontana, M.D., Ph.D., assistant professor of medicine at Washington University in St. Louis and an investigator at the Istituto Superiore di Sanita, Rome, Italy, "This is the first study to demonstrate that long-term calorie restriction with optimal nutrition has cardiac-specific effects that ameliorate age-associated declines in heart function."
Researchers Find Pathways Linking Caloric Restriction To Aging Process - "Researchers at the University of Washington have found a genetic pathway linking nutrient response and the aging process, they report in the Nov. 18 issue of the journal Science. Scientists have long known that dramatically reducing food intake boosts the lifespan of model organisms such as mice, but the new results point to a possible mechanism through which drastic calorie restriction affects aging."
