Abstract

The results of the present study show the glycemic index GI values calculated using the trapezoidal rule, of fried plantain, boiled plantain, roasted plantain, fried cocoyam, boiled cocoyam and roasted cocoyam were 88.8, 96.5, 92.0, 88.5, 97.3 and 80.0, respectively. Maximum values (96.5 and 97.3) was recorded for boiled plantain and boiled cocoyam while minimum GI (80) was recorded for roasted cocoyam. As evident, most of these foods have a high GI value (i.e., GI=70 0r more). The glycemic load GL values of fried plantain, boiled plantain, roasted plantain, fried cocoyam, boiled cocoyam and roasted cocoyam were 44.4, 48.25, 46.0, 44.25, 48.65 and 40, respectively. The maximum value (48.65) was recorded for Boiled cocoyam while minimum glycemic load (40) was recorded for Roasted cocoyam. These data indicate that all the cereal foods investigated in current study have high GI and GL. The incremental area under the curve (iAUC) of samples showed values as; glucose (3.75), fried plantain (3.33), boiled plantain (3.62), roasted plantain (3.45), fried cocoyam (3.32), boiled cocoyam (3.65), and roasted cocoyam (3.00). Results also show the glycemic load GL of the pulses. The mean of the glycemic index for fried plantain (44.4), boiled plantain (48.25), roasted plantain (46.0), fried cocoyam (44.25), boiled cocoyam (48.65) and roasted cocoyam (40).
