Managing Blood Sugar with Stone-Ground Barley: One of the Best Low-Glycemic Flour Options
Published on May 5, 2026
Finding the right ingredients for a health-conscious kitchen can feel like a balancing act, especially when you are managing conditions like diabetes or simply trying to maintain steady energy levels. In our experience at the Butte Creek Mill, many of our guests are surprised to learn that they don’t have to give up the joy of baking to support their wellness goals. By exploring low-glycemic flour options, such as our traditional stone-ground barley flour, you can create delicious, wholesome meals that are much gentler on your system than standard processed wheat.
Is barley flour a good low-glycemic flour option for diabetics?
Yes, stone-ground barley flour is an exceptional choice among low-glycemic flour options because it has a glycemic index (GI) of approximately 25–30, which is significantly lower than that of whole wheat or white flour. Its high content of soluble beta-glucan fiber creates a gel-like barrier in the digestive tract, slowing carbohydrate absorption and preventing sharp spikes in blood glucose levels.
What Makes Barley Flour Different?
Barley is one of the oldest cultivated grains in human history, and at our historic water-powered mill in Eagle Point, we still treat it with the same respect as the generations before us. Unlike mass-produced flours that are stripped of their character, our stone-ground barley flour is milled on the same French Burr stones that arrived here in 1872.
Because it is stone-ground, the grain is processed at lower temperatures, which helps preserve the natural oils and nutrients throughout the entire kernel. While the fiber in wheat is mostly concentrated in the outer bran, the beneficial fiber in barley is distributed throughout the whole grain. This means that even when it is ground into a fine, versatile flour, it retains its incredible health-supporting properties.
The Science of Slow Digestion
When our team looks at why barley is such a powerhouse for blood sugar management, it really comes down to how your body processes it. Most refined flours act like quick fuel, hitting your bloodstream all at once and causing a rapid spike in glucose. Our stone-ground barley flour works more like a steady burn.
The secret is beta-glucan. Think of these soluble fibers as a “tiny construction crew” that builds a temporary, natural barrier in your digestive system. This barrier slows down the “delivery trucks” of sugar and carbohydrates, ensuring they enter your bloodstream gradually. For diabetics or anyone monitoring their A1C levels, this slow release is vital for avoiding the highs and lows that lead to fatigue and inflammation.
Nutritional Benefits Beyond Fiber
A healthy diet is about more than just what you leave out—it’s about the real ingredients you put in. Stone-ground barley is naturally rich in magnesium, a mineral often lacking in modern diets but essential for helping the body secrete insulin and use glucose effectively.
We have found that incorporating barley flour into your routine provides a host of other benefits, including:
- Heart Health: The same beta-glucans that manage sugar also help lower cholesterol.
- Sustained Fullness: Because it digests slowly, barley helps you feel satisfied for longer, making it easier to manage weight.
- Essential Minerals: It is a great source of phosphorus, iron, and B vitamins.

How to Use Barley Flour in Your Kitchen
Barley flour has a wonderful, slightly nutty and sweet flavor that adds a malted profile to your baking. However, because it is lower in gluten than bread wheat, it behaves a little differently. Our team recommends starting with the 25% rule: try replacing about a quarter of the all-purpose flour in your favorite recipes with stone-ground barley flour.
It is particularly excellent for:
- Pancakes and Waffles: It creates a tender, hearty texture that holds up beautifully to toppings.
- Muffins and Quick Breads: Since these don’t require a high rise, barley flour can often be used in higher proportions here.
- Thickening Soups: Unlike cornstarch, barley flour adds a deep, earthy backbone to stews and gravies.

Frequently Asked Questions
Is barley flour gluten-free?
No, barley flour is not gluten-free. While it is lower in gluten than most wheat flours, it still contains gluten and should be avoided by those with Celiac disease or non-celiac gluten sensitivity.
How should I store stone-ground barley flour?
Because stone-ground flour retains the natural oils from the germ, it spoils more quickly than processed flours. We recommend storing it in an airtight container in your refrigerator or freezer to maintain peak freshness for up to six months.
Can I use barley flour as a 1:1 replacement for wheat flour?
In our experience, it is best to use barley flour as a partial replacement—roughly 25%—in yeast breads to ensure the loaf still has enough structure to rise. In recipes like cookies or pancakes, you can often use a higher percentage.
