According to Ominawo et al., (2007), Okpa is a better diet for the diabetics than moin-moin,(made from cowpea) as they were found to have lower values of glycemic index and blood glucose response when Okpa was administered and this may be attributed to the higher crude fiber content of bambara nut than cowpea (moin-moin) (Onimawo, 1998).
