Onion dosa
Measured glycemic index 79.7 — high — from J Food Sci Technol 2022.
Reported value — glycemic index
79.7glucose = 100
Onion dosa was assayed at 79.7 against glucose as 100, which places it in the high band on the published divisions. The preparation tested was described as “Onion dosa”.
The study that measured this glycemic index did not publish a per-food carbohydrate figure, so a glycemic load cannot be calculated from it, and this page does not substitute a figure from elsewhere.
The band describes the food. It is a group mean from a feeding study, not a prediction of what this food will do in your blood.

Nothing here can diagnose you, and nothing here is a treatment plan. Blood glucose results are interpreted by a doctor alongside your history, your symptoms and a repeat test — a single number on a screen is not a diagnosis. If any reading concerns you, or if you feel unwell, see a doctor rather than a website.
How a glycemic index is assayed
- Volunteers eat a portion of the test food containing exactly 50 g of available carbohydrate — whatever weight of that food that turns out to be.
- Their blood glucose is sampled repeatedly over the following two hours, and the area under that curve is measured.
- The same people are tested against 50 g of pure glucose, which scores 100 by definition. The test food's area is expressed as a percentage of it.
- The published value is the group mean, and it carries a standard deviation — several of the Indian values on this site have one of five points or more.
- Nothing in that sequence can be shortcut. A glycemic index cannot be derived from a composition table, so a food with no study has no glycemic index here.
GI = (area under the food's 2 h glucose curve
/ area under 50 g glucose) x 100
GL = GI x available carbohydrate in the portion (g) / 100
Bands: low 0-55 | medium 56-69 | high 70+

Scope of this record
What this page is not saying
It is not saying onion dosa is good or bad for blood sugar, and it is not recommending or discouraging it. No food treats diabetes and no food causes it on its own. Meals are eaten in combination, portions differ, and people differ.
If you have diabetes, prediabetes, or a result that worries you, what belongs on your plate is a conversation with a doctor or a registered dietitian who has seen your reports.

General information only — NOT medical advice, and never a diagnosis. Only a doctor can interpret your results and diagnose or treat diabetes.
