The key to aging slowly?
Limiting carbohydrates and reduce calories, say scientists
Low calorie diets affect the activity levels of 900 different genes: they reduce the risk of heart disease and stroke and positively affect brain function, slowing down, then, the aging process of the body.
An experimental study suggests for the first time that the food restriction - especially of carbohydrates - can operate by manipulating the function of a much larger group of genes. The food restriction has been known for decades as being able to extend the life of a series of animals.
Dr. Stephen Ginsberg, a neuroscientist at the Langone Medical Center at New York University who led the study, said: 'Our study shows that caloric restriction stops practically levels of gene expression involved in the phenotype of aging. Calorie restriction does not mean 'fountain of youth' but delay the effects of aging and age-related diseases. "
Dr. Ginsberg said that the benefits of such diets include a reduced risk of heart disease, hypertension and stroke, but also extends the genetic impact on memory and learning functions of the brain.
For the study, female rats, and as people are more prone to dementia than males, were fed food that had 30 percent fewer calories than other mice. The results were presented at the Society for Neuroscience annual meeting in Washington DC.
"As we know, many people find it difficult to maintain a low calorie diet for a long time, although it has been shown to have benefits for the health of the brain. It 'important to maintain a balanced and healthy diet, especially in old age, although it requires commitment. So the best way to maintain a healthy brain in old age is not smoking, maintaining a healthy weight, have a balanced diet, drinking alcohol in moderation and keep blood pressure and cholesterol under control. "the researchers conclude.
