A study analyzes in old rats the effects of a calorie-restricted diet on the hippocampus, a brain structure that is critical in learning and memory processes. The results corroborate that there is a cognitive improvement derived from diet, linked to a reduction in the levels of inflammation and neuronal loss in the hippocampus. It has been described that some of the brain alterations observed during aging are related to the cognitive dysfunction that manifests naturally as we age.
