WHAT IS GI?
GI describes how quickly a carbohydrate-containing food raises blood glucose compared with a reference food.
🐢
LOW GI
Generally associated with a slower rise.
🏎️
HIGH GI
Generally associated with a faster rise.
⚖️
GI IS NOT A HEALTH SCORE
GI describes the speed of the glucose rise — not whether a food is healthy or unhealthy.
💉
WHAT IS PRE-BOLUS?
Giving rapid-acting insulin before eating when appropriate according to the individual's diabetes-care plan.
⏱️
WHY?
The goal is to better match insulin action with the rise in glucose from food.
⚠️
IMPORTANT
Pre-bolus timing is individualized. There is no universal number of minutes. Always follow your own diabetes-care plan and the guidance of your healthcare team.
