What is it?
The glycemic index (GI) is a scale from 0 to 100 that ranks carbohydrate-containing foods based on how quickly they raise blood sugar (glucose) levels. Foods are categorized as low (55 or less), medium (56-69), or high (70 or more). High-GI foods are rapidly digested, causing a sharp spike in blood sugar, while low-GI foods break down more slowly, leading to a gradual release of glucose. Factors like cooking methods, ripeness, and food processing can all influence a food's GI score.
Why is it trending?
The glycemic index is gaining popularity as a tool for health-conscious individuals beyond just diabetes management. Many are turning to low-GI diets for weight management, as these foods can increase feelings of fullness and support fat loss. There is a growing awareness of how managing blood sugar impacts overall wellness, from energy levels to reducing the risk of chronic illnesses like heart disease and type 2 diabetes. As people move away from restrictive diets, the GI offers a more nuanced way to choose healthier carbohydrates.
How does it affect people?
Adopting a low-GI diet can have several positive effects. For individuals with type 2 diabetes, it's a valuable tool for improving blood sugar control. It can also contribute to weight loss by promoting satiety, which helps reduce overall calorie intake. Some studies show that low-GI diets can help lower total and LDL (bad) cholesterol levels, supporting cardiovascular health. By preventing sharp spikes and subsequent crashes in blood sugar, people may experience more stable energy and mood throughout the day.
