The term "glycemic index" refers to a ranking system for carbohydrates based on their impact on blood sugar levels. Foods with a high glycemic index increase blood glucose rapidly, while those with a low glycemic index result in a slower, more gradual rise. This concept is essential for individuals managing conditions like diabetes, as it helps in selecting foods that promote stable blood sugar levels. Incorporating low glycemic index foods into the diet can also assist in weight management and improve overall metabolic health. Understanding glycemic index can empower individuals to make healthier dietary choices.
