Abstract
White Yam and Soya Beans is one of the commonly consumed carbohydrate staples. This work determined the Carbohydrate and Amylopectin content and glycemic index (GI) of white yam (Dioscorea rotundata) varying with soya beans (Glycine max). Yam tubers were obtained (peeled, sliced, washed) and beans were also obtained ( washed) then some yam and beans were dried, while some were boiled in water.
The cooked yam and beans sample were eaten by 1 individual about the age of 23. A glucometer was used to measure the blood glucose concentrations of the test individual before consuming the yam and beans diets and after the 15 th, 30th, 45th, 60th, and 90th, of consumption which was found to be 108mg/dl, 142mg/dl, 150mg/dl, 145mg/dl,120mg/dl, while for that of soya beans to be 91mg/dl, 105mg/dl, 115mg/dl, 100mg/dl and 111mg/dl. The average incremental area under the curve (IAUC) obtained from the recorded blood concentrations were used to calculate the GI of various White Yam and Soya Beans diets and the combinatrion of both is 210mg/dl for White yam and 585mg/dl for Soya Beans.
