Effect of different starchy foods in composite meals on gastric emptying rate and glucose metabolism. II. Comparisons between potatoes, rice and white beans in diabetic subjects.

Composite meals with mashed potatoes, polished rice or mashed white beans were administered to eleven diabetic subjects (seven Type II and four Type I). As earlier reported in non-diabetic subjects (Torsdottir et al., 1984) the difference in gastric emptying, measured by 51Cr-technique, correlated with the difference in blood glucose response when comparing the meals including mashed potatoes and polished rice, rs = 0.93 (P less than 0.01), but no such correlation was found after the meal with white beans.
