Fasting baseline blood sample from a catheter will be collected after which baseline cognitive performance measures will be assessed. After completing baseline measures, subjects will receive a standard breakfast meal along with a beverage containing different fruits according to the randomization sequence. Additional blood samples will be taken at 30, 60, 120, 180, 240, 300, 360, and 480 minutes after the start of the breakfast meal. Additional cognitive tests will be performed at the 120, 240, 360, and 480 minute time points. A standardized lunch will be provided between the 360 and 480 minute time points.
