Pumpkin is a healthy fruit and contains many nutrients. Pumpkin had also been
reported as having anti diabetic function. The aim of this study was to determine the
glycemic responses of pumpkin muffin among healthy adults. Twelve subjects (6 males
and 6 females), with mean age of 21.75 years and mean BMI of 21.39kg/m2 were
randomly fed with two types of muffins, which were muffin made from 100% wheat
flour and muffin made with 20% pumpkin puree and 80% wheat flour. Subjects were fed
with meals after a 10 - 12 hours fasting and each test meal contained 50g of available
carbohydrate within 15 minutes. Capillary finger-prick blood samples were obtained at
0. 15, 30, 45, 60, 90 and 120 minutes. It was found that there was no significant
difference between the blood glucose responses for both types of muffins. For the
control muffin, the blood glucose response at 30 minutes was significantly higher
compared to the blood glucose responses at 90 minutes and 120 minutes. For the
pumpkin muffin, the blood glucose response at 30 min was significantly higher than the
blood glucose responses at 0, 90 and 120 minutes. Both muffin samples reached the
blood glucose response peak at 30 minutes after ingesting test meals. There was no
significant difference in the blood glucose responses between genders for both types of
muffins. The incremental area under curve (IAUC) for the pumpkin muffin was
16.01±2.46, which was significantly lower than that of control muffin, whereby the
lAUC was 27.69±1.80. The glycemic index value for the control muffin was 65.17±9.81
while the glycemic index value for pumpkin muffin was 68.13± I 0.89. The pairedsample
t-test showed that there was no significant difference for the glycemic index value
between the control muffin and pumkin muffin. The GL value for control muffin was
32.59 and the GL value for pumpkin muffin was 34.07. Both types of muffins were
classified under high glycemic index foods. |
