Understanding Glycemic Index
Glycemic Index (GI) is a crucial measure for managing blood sugar levels. It provides insights into how different foods impact glucose in the body, which is especially important for people with diabetes or those concerned about their overall health.
Definition of Glycemic Index
Glycemic Index is a numerical scale that ranks carbohydrate-containing foods based on how quickly they raise blood sugar levels. Foods are compared to pure glucose, which has a GI of 100. Low GI foods (55 or less) cause a slower, more gradual rise in blood sugar. Medium GI foods range from 56 to 69, while high GI foods (70 or above) cause rapid spikes in blood glucose.
Kiwi has a relatively low GI of 50, making it a favorable fruit choice for blood sugar management.
Importance for Blood Sugar Management
Understanding GI is vital for maintaining stable blood sugar levels. Low GI foods help:
- Prevent sudden blood sugar spikes

- Improve long-term blood glucose control
- Support weight management
- Lower risk of type 2 diabetes and cardiovascular diseases
For individuals with diabetes, choosing low GI foods like kiwi can be part of an effective strategy to manage their condition. It allows for better glycemic control and potentially reduces the need for medication.
Glycemic Load Vs. Glycemic Index
While GI is useful, Glycemic Load (GL) provides a more comprehensive picture of a food’s impact on blood sugar. GL takes into account both the GI and the amount of carbohydrates in a serving.
GL = (GI x grams of carbohydrates per serving) / 100
A low GL is 10 or less, medium is 11-19, and high is 20 or more.
Kiwi has a GL of 7.3, categorizing it as a low GL food. This means that a typical serving of kiwi has a minimal impact on blood sugar levels, making it a smart choice for those monitoring their glucose intake.
