Understanding Glycemic Index
The glycemic index provides valuable insights into how foods affect blood sugar levels. It serves as a tool for managing glucose response and making informed dietary choices.
Glycemic Index Basics
The glycemic index (GI) measures how quickly carbohydrates in food raise blood glucose levels. Foods are ranked on a scale from 0 to 100, with pure glucose assigned a value of 100. Low GI foods score 55 or less, medium GI foods range from 56 to 69, and high GI foods score 70 or above.
Low GI foods cause a gradual rise in blood sugar, while high GI foods lead to rapid spikes. Factors affecting a food’s GI include:
- Fiber content
- Processing methods
- Cooking techniques
- Ripeness (for fruits)
Glycemic Load and Its Significance
Glycemic load (GL) combines the GI with the actual amount of carbohydrates in a serving. It provides a more accurate picture of a food’s impact on blood sugar. To calculate GL, multiply the GI by the grams of carbohydrates per serving and divide by 100.
GL categories:
- Low: 10 or less
- Medium: 11-19
- High: 20 or more
GL is particularly useful for foods with a high GI but low carbohydrate content. For example, watermelon has a high GI but a low GL due to its high water content and relatively few carbohydrates per serving.
