Understanding Glycemic Index and Glycemic Load
The glycemic index and glycemic load are important concepts for managing blood sugar levels. These measures provide valuable insights into how different foods affect glucose in the body.
Basics of Glycemic Index
Glycemic index (GI) ranks carbohydrate-containing foods based on how quickly they raise blood sugar levels. Foods are scored on a scale of 0 to 100, with pure glucose given a value of 100.
Low GI foods (55 or less) include most fruits and vegetables, legumes, and whole grains. They cause a slower, more gradual rise in blood sugar.
Medium GI foods (56-69) include foods like sweet corn, bananas, and basmati rice.
High GI foods (70 or above) such as white bread and potatoes cause rapid spikes in blood glucose. These are best consumed in moderation.
Glycemic Load Explained
Glycemic load (GL) considers both the quality and quantity of carbohydrates in a food. It provides a more accurate picture of a food’s impact on blood sugar.
To calculate GL, multiply the GI by the number of carbohydrate grams in a serving, then divide by 100.
GL values are categorized as:
- Low: 10 or less
- Medium: 11-19
- High: 20 or more
Green beans have a low GL of about 2, making them an excellent choice for blood sugar management. This low GL is due to their low carbohydrate content and low GI.
