Glycemic Index

GLYCEMIC INDEX

The glycemic index (GI) is a system that ranks carbohydrates on a scale from 0 to 100 based on how much they raise blood sugar levels after consumption. Foods with a high GI are digested and absorbed quickly, causing a rapid rise and fall in blood sugar. Foods with a low GI are digested and absorbed more slowly, leading to a slower and lower rise in blood sugar levels.

For cyclists, understanding the GI is important for managing energy levels. High GI foods are useful for a quick energy boost during or immediately after exercise, while low GI foods are better for sustained energy before long rides.
