Understanding the Glycemic Index (GI) and Glycemic Load (GL)
Before diving into specific food recommendations, it's essential to understand the Glycemic Index (GI) and Glycemic Load (GL). These metrics are crucial in determining how foods affect blood sugar. What Is An A1C Test Understanding Your Blood Sugar Over Time
-
Glycemic Index (GI): This ranks foods on a scale of 0 to 100 based on how quickly they cause a rise in blood sugar levels. Foods with a high GI (70 or more) are rapidly digested and absorbed, leading to a significant spike in blood sugar. Conversely, low GI foods (55 or less) are digested and absorbed more slowly, resulting in a gradual rise in blood sugar. Simple Breakfast Ideas To Help Prevent Morning Blood Sugar Spikes

Glycemic Load (GL): This considers both the GI and the amount of carbohydrates in a serving of food. It provides a more accurate picture of a food's impact on blood sugar. GL is calculated as: (GI x grams of carbohydrates per serving) / 100. Foods with a GL of 10 or less are considered low, 11-19 is medium, and 20 or more is high.
| Metric | Description | | -------------- | ------------------------------------------------------------------------------------- | | GI (Low) | 55 or less | | GI (Medium) | 56-69 | | GI (High) | 70 or more | | GL (Low) | 10 or less | | GL (Medium) | 11-19 | | GL (High) | 20 or more |
