Glycemic Load Calculator
Estimate the glycemic load (GL) of a food portion using its glycemic index and carbohydrate content.
How to Use the Glycemic Load Calculator
- Enter the glycemic index of the food (0–100).
- Enter the grams of available carbohydrates in the portion (subtract fibre).
- Click Calculate to see GL and its level.
使用例
- •Meal planning for diabetes or pre-diabetes.
- •Choosing between foods with similar calorie content.
- •Sports nutrition and recovery.
計算式
GL = (GI × available carbs in grams) / 100. GL ≤ 10 is low, 11–19 is medium, ≥ 20 is high.
よくある質問
Why is GL more useful than GI alone?
GI tells you how fast the carbs in a food raise blood sugar, but not how many carbs are actually in a portion. GL combines both — glycemic index and portion size — to estimate the real impact of a meal.
What counts as a low-GL day?
Most nutritionists suggest keeping the total daily glycemic load under ~100 for a balanced diet. Individual targets depend on activity level and medical context.
