Cutting back the calories may do more than whittle your waistline; it could protect your brain from the effects of aging. A new study suggests that calorie restriction can help slow the normal process of cell death that happens with age.
Researchers say the body naturally goes through a process known as apoptosis, or cell death, to destroy old cells so new ones can be made, and many factors can alter this process. Age-related diseases, such as Alzheimer’s and Parkinson’s, cause a higher-than-normal loss of cells in the brain, which can lead to loss of function.
Previous studies have suggested that calorie restriction can boost life span and mental capacity. That prompted researchers to look at whether cutting calories might also play a role in protecting aging brain cells. They compared levels of proteins indicating brain cell death in two groups of rats. One group was given unrestricted access to food
