Eating less could help you remember more, a study suggests. Among volunteers with an average age of 60, the Telegraph reports, those instructed to eat 30% fewer calories improved their memory test scores by 20% compared to those asked to maintain their diets or eat 20% more. The finding fuels hope for progress combating dementia, of which memory loss is an early sign.
Researchers speculate that insulin created to help process food may damage nerves in the brain. Many experts believe this finding, and others like it, prove a link between healthy eating and the onset of Alzheimer’s or dementia. Another study last year found high cholesterol increased the risks, while another found smoking and drinking speed memory deterioration. (More memory stories.)
