Glycemic response to a peanut butter and cracker snack in noninsulin dependent diabetics and nondiabetics
MetadataShow full item record
The purpose of this study was to observe and compare the blood glucose response of individuals with documented noninsulin dependent diabetes (NIDDM) and controls after they consumed a peanut butter and cracker snack product (Austin "Toasty" crackers). Twenty-one subjects with NIDDM (15 with current NIDDM and 6 with previously abnormal glucose tolerance [prevAGT]) and 11 controls participated. Height, weight, body mass index (BMI) and age of subjects were recorded and statistically compared. Subjects tested their own blood glucose using the One Touch II glucometer, and participated on two separate occasions which were designated session 1 and session 2.
Blood glucose was measured before eating the test food, every 15 (+3) minutes for two hours after eating, and at 150 and 180 minutes. Mean peak blood glucose value and the time at which glucose peaked were identified and compared among the groups. Repeated measures ANOV A was used to compare blood glucose response curves of the NIDDM group, the control group, and the PrevAGT group; slope of the line after the peak was of interest. The null hypothesis was that the groups would not differ in their blood glucose responses.
