Abstract
Results of tests in 10 healthy adults to determine how postprandial glucose and serum insulin profiles vary after the vegetable salad intake sequence of cabbage, olive oil, and vinegar was changed with rice showed that ingesting salad before rice significantly decreased incremental plasma glucose (ΔC) 20, 30, and 45 minutes postprandially (p<0.01). The time until maximum plasma glucose (ΔCmax) was reached was delayed 40 minutes (p<0.01), compared to when salad was ingested after rice. ΔCmax decreased by a mean 21% and the incremental area under the curve from 0 to 120 minutes postprandially decreased by a mean 39%. Serum insulin varied parallel with plasma glucose, suggesting that postprandial insulin secretion is controlled. Ingesting salad before rice effectively suppresses postprandial plasma glucose.
