Condition or disease
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 series of memory tests and an additional 3 blood glucose level tests are administered approximately 15 minutes later. A minimum of 1 week afterward, the subjects return and receive the alternate sweetener followed by additional memory tests.
