This chapter explores the role of diet and nutrition on cognitive aging and the cognition of animals and human beings. The association of dietary restriction with positive effects on cognition and health are explored along with the role of moderate physical stress in improving health. The chapter explores the side effects of excess energy intake on human beings’ cognitive functioning. The increased risk of Alzheimer’s disease is also linked to excess energy consumption. In animals, excess fat intake reduces the neuronal plasticity and learning capacity of the brain. Mechanisms including glucose regulation, the hippocampal circuits’ plasticity and oxidative stress, among others, are being studied to provide answers regarding the positive effect of dietary restriction.

Keywords:   cognitive aging, dietary restriction, excess energy intake, glucose regulation, oxidative stress
