A University of Milan study compared buckwheat, oats, and, quinoa to see if any of them showed promise in helping with appetite control. In three experiments – one for each grain – subjects’ satisfaction and subsequent calorie consumption were compared, after eating the study grain and after eating wheat or rice. All three study grains had a higher Satiating Eﬃciency Index (SEI) than wheat or rice; white bread was in fact lowest in appetite satisfaction. Unfortunately, even after feeling fuller from eating the study grains, the subjects did not cut their calories at the next meal!
