Detailed Description:

Subjects fast for 8 hours before receiving a test to determine their blood glucose levels. Following this test, subjects are randomized to receive either a glucose or saccharin sweetened drink.

A minimum of 1 week afterward, the subjects return and receive the alternate sweetener followed by additional memory tests.
