Abstract

The glycemic index (GI) of peanut butter and jam sandwich with guava was investigated among healthy subjects. Ten subjects (5 males, 5 females; BMI 21.3 ± 1.35 kg/ m² ) consumed a reference meal of 50 g glucose twice and one test meal (peanut butter and jam sandwich with one serving of guava) after a 12 hour overnight fast. Capillary blood samples were taken at time 0 (fasting), 15, 30, 45, 60, 90, and 120 min after the consumption of test or reference meal. The mean GI value of the test meal was calculated. iAUC of the test meal was 176.1 ± 69.79 mmol' min/ L, which was not significantly different from the iAUC of reference meal 212.1 ± 68.15 mmol' minI L (p>0.05). The GI of the test meal was 86 ± 29.90, categorized as high GI. The GI measured was 19.4% higher than the GI predicted, which was 72. The difference of GI was 14 units.
