What is the reference food for GI?

Explanation:
Glycemic Index compares how quickly a food raises blood glucose by comparing it to a standard reference food. That reference provides a fixed benchmark so every food’s response can be expressed as a percentage of that standard. In many PE resources, white bread is used as the reference food and is set to a value of 100. Other foods are then rated in relation to white bread’s glucose response. So, white bread is the standard used as the baseline for GI in this context, making it the best answer.
