By incorporating plums into a balanced diet, individuals can enjoy a tasty fruit while supporting their nutritional goals and blood sugar management efforts.

Understanding the Glycemic Index

The glycemic index is a valuable tool for managing blood sugar levels. It provides insights into how different carbohydrate-containing foods impact glucose in the body.

Definition of Glycemic Index

Glycemic Index (GI) is a scale from 0 to 100 that ranks foods based on their effect on blood sugar levels. Foods with a high GI are rapidly digested and cause a quick spike in blood glucose. Low GI foods are digested more slowly, resulting in a gradual rise in blood sugar.

The GI scale is typically categorized as follows:

• Low GI: 55 or less
• Medium GI: 56-69
• High GI: 70 or higher

This classification helps individuals make informed food choices, especially those managing diabetes or weight.

Glycemic Load versus Glycemic Index

While GI measures how quickly a food raises blood sugar, Glycemic Load (GL) takes into account both the GI and the amount of carbohydrates in a serving. GL provides a more accurate picture of a food’s impact on blood glucose levels.

To calculate GL, multiply the GI by the grams of carbohydrates in a serving, then divide by 100. For example, a food with a GI of 50 and 10 grams of carbs per serving would have a GL of 5.

GL is categorized as:

• Low GL: 10 or less
• Medium GL: 11-19
• High GL: 20 or more

GL is particularly useful when comparing foods with similar GI but different carbohydrate content.
