Understanding the Glycemic Index
The glycemic index provides valuable insights into how foods affect blood sugar levels. It helps differentiate between carbohydrates that cause rapid spikes and those that lead to more gradual changes.
Defining Glycemic Index
The glycemic index (GI) ranks carbohydrate-containing foods on a scale of 0 to 100 based on how quickly they raise blood glucose levels. Foods with a high GI (70 or above) are rapidly digested and cause sharp spikes in blood sugar. Medium GI foods (56-69) lead to moderate increases. Low GI foods (55 or below) are slowly digested and absorbed, resulting in gradual rises in blood glucose.
Some examples of GI rankings:
- High: White bread (75), Watermelon (72)
- Medium: Sweet corn (60), Banana (58)
- Low: Lentils (32), Butternut squash (51)
Glycemic Load Vs Glycemic Index
While the glycemic index measures the quality of carbohydrates, glycemic load (GL) considers both quality and quantity. GL is calculated by multiplying the GI by the amount of carbohydrates in a serving, then dividing by 100.
GL ratings:
- Low: 10 or less
- Medium: 11-19
- High: 20 or more
Glycemic load provides a more accurate picture of a food’s impact on blood sugar levels. For instance, watermelon has a high GI but a low GL due to its low carbohydrate content per serving.
