Calorie Restriction can protect the brain

Redoxcope: Interview | M. C. WiderCalorie Restriction Can Protect the Brain

by Maria Celia Wider

For decades, caloric restriction has been known to enhance longevity and the prevent age-related diseases. However, the processes responsible for these effects are not yet fully understood. Now, Redoxoma Network researchers have found the mechanism in which caloric restriction facilitates mitochondrial calcium retention capacity in the brain, resulting in protection against excitotoxic damage, which is related to neuronal loss in diseases such as stroke, Parkinson´s and Alzheimer’s. “Because we determined caloric restriction´s mechanism of action, we may be able to develop drugs to increase mitochondrial calcium uptake in mitochondria in a manner that is not dependent

Mitochondrial metabolism and central nervous system dysregulation govern an overeating but low energy conversion efficiency response to intermittent-feeding

The ideal type of diet is a long-sought goal that has not been fulfilled so far, both for preventive as well as therapeutic purposes. At the same time, caloric restriction has been well demonstrated to afford increase in lifespan in several species. Intermittent feeding has been used as a substitute for caloric restriction both by overweight or obese individuals (frequently without medical supervision) or, experimentally, as a mechanistical tool to understand the physiology of lifespan extension. These intermittently-fed animals, indeed display decreased body mass, but surprisingly overall caloric intake is similar to that of ad libitum-fed animals. Work performed by the CEPID-Redoxoma
