The glycemic index (GI) measures how carbohydrates in foods affect blood sugar levels. Ranked on a scale from 0 to 100, it helps identify foods that cause gradual or rapid spikes. Low GI foods, scoring 55 or below, promote stable blood sugar levels, benefiting overall health and managing conditions like diabetes effectively. Understanding GI supports informed dietary choices for better glucose control and sustained energy.
What is the Glycemic Index?
The glycemic index (GI) is a numerical scale that ranks foods based on how quickly they raise blood sugar levels after consumption. Foods are scored from 0 to 100, with pure glucose set at 100. Low GI foods (55 or below) digest slowly, causing gradual glucose release, while high GI foods (70 or above) lead to rapid spikes. The GI helps individuals, especially those managing diabetes, make informed choices to stabilize blood sugar levels. It considers the type and amount of carbohydrates, as well as other nutrients like fiber, protein, and fat, which slow digestion. By focusing on low GI foods, individuals can maintain steady energy levels and reduce the risk of chronic health conditions. Understanding the GI is essential for creating balanced meal plans that prioritize long-term health and well-being.
