**What is GI?
The Glycemic Index (GI) measures how quickly carbohydrates in food are digested and absorbed, and how fast they raise blood glucose levels.
Scale: 0–100
Reference: pure glucose or white bread (GI = 100).
**GI Classification
Low GI: ≤ 55
Medium GI: 56–69
High GI: ≥ 70
**Characteristics of Low GI Foods
Digested and absorbed more slowly.
Cause a gradual rise in blood sugar.
Provide longer satiety (feeling of fullness).
Help regulate blood sugar and insulin response.
**Why it matters
For people with diabetes: helps maintain stable blood sugar levels.
For general health: reduces sugar spikes, supports weight control.
For athletes: choosing the right GI foods can help with energy supply and recovery.
