Understanding Glycemic Load
Glycemic load (GL) is a metric that accounts for both the glycemic index (GI) and the total available carbohydrate content in a food serving. The GI ranks carbohydrates on a scale from 0 to 100 based on how quickly they raise blood sugar. A low GI is 55 or less, a medium GI is 56–69, and a high GI is 70 or higher. A low GL is 10 or less, a medium GL is 11–19, and a high GL is 20 or more.
Several factors contribute to a bread's lower GL, including high fiber content, sprouting, fermentation, and a dense texture. Fiber slows digestion, sprouting breaks down starches, fermentation produces organic acids, and a dense texture slows digestion.
Top Contenders for the Lowest Glycemic Load
Certain types of bread are consistently low on the glycemic scale. Prioritizing options with whole and sprouted grains can aid in blood sugar management.
Ezekiel (Sprouted Grain) Bread
Ezekiel 4:9 bread, made from sprouted grains and legumes, has a low glycemic impact with a reported GI of 36. The sprouting process increases fiber and protein, improving digestibility.
100% Whole Grain Rye Bread
This dense bread uses only whole grain rye flour. Whole grain rye has a GI between 30 and 40, leading to a slower blood sugar rise. Its slow digestion supports sustained energy.
Pumpernickel Bread
Pumpernickel, a dense bread from coarsely ground rye flour and slow baking, typically has a low GI of 41-45 and is high in fiber, supporting blood sugar control.
Flaxseed Bread
Breads with flaxseeds are rich in fiber and healthy fats, lowering their glycemic effect with some types having a GI of 30–40.
Sourdough Bread
Sourdough's natural fermentation lowers its GI. Lactic acid produced helps moderate the glycemic response. A 2024 article noted a GI of 54 for sourdough wheat bread.

Making Smarter Bread Choices
Strategies to further reduce a meal's glycemic impact include pairing bread with protein and healthy fats, controlling portion sizes, and reading labels. Look for at least 3-5 grams of fiber per serving and ensure the first ingredient is a whole grain. Gluten-free options like chickpea flour bread can also be low GI.
Conclusion
Certain breads, particularly sprouted grain varieties like Ezekiel, dense 100% whole grain rye, and traditionally fermented sourdough, offer a lower glycemic load, helping maintain stable blood sugar. Understanding factors like fiber, sprouting, and fermentation and using mindful eating strategies allows bread to be part of a healthy diet.
What bread has the lowest glycemic load? The Verdict
Breads with the lowest glycemic load include sprouted grain breads like Ezekiel, 100% whole grain rye, and Pumpernickel, due to their high fiber content and unique processing.
What bread has the lowest glycemic load?
Ezekiel (sprouted grain) bread is often cited for its low glycemic index and load, with a reported GI of 36.
What bread is good for high blood sugar?
High-fiber breads like sprouted grain, 100% whole grain rye, and sourdough are beneficial for managing high blood sugar as they lead to a slower rise in glucose.
Is sourdough bread low glycemic?
Yes, sourdough bread has a lower glycemic index (around 54) than commercial white bread because fermentation slows carbohydrate digestion.
What is the difference between glycemic index and glycemic load?
The glycemic index (GI) measures how quickly a food raises blood sugar, while the glycemic load (GL) considers both GI and portion size for a more accurate estimate of blood glucose effect.
Does adding protein or fat reduce bread's glycemic impact?
Yes, pairing bread with protein or healthy fats can lower its glycemic impact by slowing digestion and sugar absorption.
Is whole wheat bread a low glycemic option?
No, standard whole wheat bread typically has a medium GI (around 71), which is better than white but higher than sprouted grain or 100% rye bread.
What should I look for when buying low-glycemic bread?
Check for whole grains listed first, high fiber (3-5 grams/serving), and low added sugars. Look for 'sprouted,' '100% whole grain rye,' or 'sourdough'.
What bread should I avoid for managing blood sugar?
Avoid refined flour breads like white bread, sweet breads, bagels, and most commercial pastries due to their high glycemic load.
Can I bake my own low-glycemic bread?
Yes, using low-glycemic flours like almond, chickpea, or coconut can create lower glycemic impact options.
How does sprouting lower the glycemic load?
Sprouting breaks down starches and increases fiber, leading to a slower release of glucose into the bloodstream.
