And that translates to more than 50 million Americans, according to a report by the Centers for Disease Control and Prevention.
The National Academy of Medicine has issued reports showing that health and vitality aren’t keeping pace with longevity, says Dr. David Katz, director of the Yale University Prevention Research Center.
"Although medical advances help delay death, they cannot confer genuine vitality," Katz says. “The consequence of a longer life span, but a health span that is not keeping pace, is more years encumbered by chronic maladies and disabilities."
By eating well, being active and not smoking, as much as 80 percent of chronic diseases could be prevented, as well as the disability that accompanies them, Katz says.
