A carb-restricted diet could slow the aging process
Diets that reduce the number of calories derived from carbohydrates might help deter some aspects of aging, according to a new study from NYU Langone Medical Center.
Researchers found that these types of reduced-calorie diets can slow the activity levels of nearly 900 different genes that are linked to aging and memory in the brain.
"Our study shows how calorie restriction practically arrests gene expression levels involved in the aging phenotype - how some genes determine the behavior of mice, people, and other mammals as they get old," said senior study investigator and neuroscientist, Dr. Stephen D. Ginsberg.
30-percent calorie reduction may show significant results
In the study, female mice were fed food pellets that had 30 percent fewer calories than pellets fed to other mice.
Researchers then analyzed the rodents' brains, focusing specifically on the hippocampal region - an area that is affected in the early stages of Alzheimer's disease.
Calorie restriction, especially when it comes from carbohydrates, has previously been linked to reduced risk for heart disease, hypertension and stroke - findings that are supported by the current research.
And while calorie restriction isn't the "fountain of youth," Ginsberg said it provides evidence for the role that diet plays in fighting age and age-related disease.
