Brief Summary:
The purpose of this project is to determine whether restoring the post-prandial metabolic/inflammatory balance via supplementation with raspberries results in improved cognitive performance, and if these enhancements are mediated through improvements in vascular function.

Condition or disease Intervention/treatment Phase
Aging Age-related Cognitive Decline Obesity Dietary Supplement: Active breakfast Dietary Supplement: Control breakfast Not Applicable

Detailed Description:
This study will investigate the effects of red raspberry in a relevant human model of metabolic disturbance to understand the relationship between red raspberry intake, metabolic and immune- balance and cognitive and psychomotor performance in older/over weight adults. A secondary goal of the project is to provide data on central vascular function in relation to metabolic-, inflammatory- and cognitive outcomes. Our primary working hypothesis is that red raspberries will improve metabolic- / inflammatory- balance in older overweight and obese adults resulting in improved cognitive and psychomotor performance mediated in part through improvements in vascular function. Two main objectives have been devised to meet the goals of the project and test our hypotheses: 1) Evaluate the effects of acute dietary raspberry intake on metabolic-associated impairments in cognitive and psychomotor function in overweight/obese adults (55-70y) following a meal challenge. 2) Evaluate the effects of acute dietary raspberry on measures of vascular function
