The term “glycemic index” (GI) refers to a ranking of foods based on their effect on blood sugar levels. Foods with a high GI are digested quickly, causing rapid spikes in blood glucose, while low-GI foods result in a slower, more gradual increase. This index helps in selecting foods that provide sustained energy, which is particularly beneficial for individuals managing diabetes or seeking to control their weight. Integrating low to moderate GI foods can enhance overall health and stabilize energy levels throughout the day.
