Load = index × carbohydrates in the portion ÷ 100. Indexes from the app's reference table, carbohydrates from the Ciqual 2025 table; results rounded.
The glycemic index
How quickly a food containing carbohydrates raises blood sugar, compared with pure glucose (100).
- Low: up to 55
- Medium: 56 to 69
- High: 70 and over
The glycemic load
It takes into account how much you actually eat. A high-index food can have a small load if the portion is modest. A load counts as low up to 10 and high from 20. Glyami adds it up over the day, with a guide value of 80 that you can adjust.
