                                Minimally processed cereals like steel-cut oats and whole grain barley are known to have a significantly lower glycemic index (GI) than their refined counterparts. Understanding which cereal has the lowest glycemic index is crucial for managing blood sugar levels, especially for individuals with diabetes or those seeking sustained energy throughout the day. High GI foods cause rapid spikes in blood sugar, while low GI options are digested slowly, providing a steady release of glucose.
