As the aging population increases world-wide and incidence of dementia climbs in concert, lifestyle interventions to prevent or delay cognitive decline are of great interest for reducing the number of individuals with dementia and curbing the demand for age-related healthcare services. These preventative approaches that focus on factors like diet and exercise, have the potential to not only provide much needed tools to healthcare providers, but also have the potential to inform public health policy as well. Identifying a brain healthy diet and understanding its implications for both cognitive performance and brain structure underlies the significance of this research aim.
