Understanding the Glycemic Index
What Is the Glycemic Index?
The glycemic index is a numerical system that measures how quickly carbohydrate-containing foods raise blood glucose levels after consumption. It ranks foods on a scale from 0 to 100, with pure glucose assigned a value of 100. Foods with a high GI (70 and above) cause rapid spikes in blood sugar, while low GI foods (55 and below) lead to slower, more gradual increases.
Why Is the Glycemic Index Important?
Understanding the GI helps individuals make informed dietary choices to:
- Manage blood sugar levels effectively
- Control appetite and reduce cravings
- Support weight management
- Improve overall metabolic health
- Reduce the risk of developing type 2 diabetes and cardiovascular diseases
