In a randomized, crossover, acute feeding trial in overweight/obese adults with T2DM, compared with isocaloric intake of basmati rice, intake of 3 different preparations of boiled, roasted, or boiled then cooled potatoes showed no significant impact on postprandial triglycerides, glucose, or insulin, except for the finding that boiled and cooled potatoes increased postprandial insulin compared with basmati rice [44]. This evidence concerns the gene INS and type 2 diabetes mellitus.
