The addition of almonds to breakfast -- long hailed as the most important meal of the day -- may help sustain feelings of fullness based on the results of a recent study. The study, Acute and second-meal effects of almond form in impaired glucose tolerant adults: a randomized crossover trial, published in February 2011 in the Journal of Nutrition and Metabolism, illustrates that consuming a breakfast containing almonds (a low glycemic index food) aids in stabilizing blood glucose levels for the better part of the day -- while also keeping study participants satiated for a longer period of time.
