French or Vienna Bread: A High Glycemic Index Option
French or Vienna bread is a popular choice for many meals, from breakfast toast to sandwich bases. However, if you’re monitoring your blood sugar levels, it’s important to understand how this bread affects your glycemic response.
Glycemic Index and Load
Our user-friendly app features a searchable database, meal planning tools, and personalized recommendations based on your health goals.
French or Vienna bread has a glycemic index (GI) of 95, which places it firmly in the high GI category. Foods with a GI above 70 are considered high, meaning they cause a rapid rise in blood glucose levels.
The glycemic load (GL) is 47.22 for a 100g serving. This is also very high, as a GL above 20 is considered high impact on blood sugar. The glycemic load takes into account both the GI and the amount of carbohydrates in a serving, giving us a more practical measure of how a food affects blood sugar.

Impact on Blood Sugar
With its high GI and GL values, French or Vienna bread can cause significant spikes in blood sugar levels. This is primarily due to its refined flour content, which digests quickly and converts to glucose rapidly in the bloodstream.
Who Should Be Cautious
- People with diabetes or insulin resistance
- Those following a low-glycemic diet for weight management
- Individuals trying to prevent blood sugar fluctuations
Healthier Alternatives
If you’re looking for bread options with a lower glycemic impact, consider:
- Whole grain bread (GI typically between 50-70)
- Sourdough bread (fermentation process lowers GI)
- Pumpernickel bread (generally has a lower GI around 50-55)
- Bread with added seeds and nuts (higher fiber content slows digestion)
How to Reduce the Glycemic Impact
If you still want to enjoy French or Vienna bread occasionally:
- Pair it with protein and healthy fats to slow digestion
- Consume smaller portions
- Choose freshly baked versions rather than pre-packaged ones
- Opt for slightly undercooked or toasted bread, which may have a slightly lower GI
Conclusion
While French or Vienna bread is delicious, its high glycemic index and load make it a food to consume in moderation, especially for those monitoring blood sugar levels. Being aware of its impact allows you to make informed choices about when and how to include it in your diet.
