The glycemic index (GI) is a ranking of carbohydrates based on their immediate impact on blood sugar levels. Foods with a high GI cause rapid spikes in blood glucose, while low GI foods result in a more gradual release of sugar. Understanding the GI is crucial for managing blood sugar levels, especially for individuals with diabetes. By choosing low GI options, one can maintain stable energy levels and reduce the risk of certain health problems. Furthermore, a lower glycemic diet is often linked to better weight management and reduced risk of chronic diseases.
