Objectives: To evaluate the effect of 5g fresh chili pepper (CAP) on glucose response after
a glucose drink and metabolic rate (MR) in Thai women.
Material and Method : The glucose response after a glucose drink was evaluated in 10
healthy women. The plasma glucose levels at 0, 15, 30 and 60 min after glucose load with and without
5 g fresh CAP were compared. Evaluation of MR was performed in an additional 12 subjects. MR was
measured by the ventilated-hood indirect calorimetry system before and for 60 min after CAP inges-
tion.
Results : The rise of plasma glucose at 30 min after CAP ingestion was significantly lower
than the rise of plasma glucose after a plain glucose drink by 20.6 per cent (p < 0.01). On the other
hand, the CAP ingestion significantly increased MR above resting MR. Moreover, MR immediately
increased by 20 per cent within a few minutes after CAP ingestion and showed a remarkable increase
of 7.2-17.4 per cent from baseline for 11 min. The significance of thermogenic change was present up
to 30 min (p
<
0.05).
Conclusions: Within 30 min after consumption of 5 g of
Capsicumfrutescens,
plasma glucose
level during the absorption period was significantly inhibited. The metabolic rate was also immediately
increased after ingestion and sustained up to 30 min.
