Spelt and Blood Sugar: What Diabetics Need to Know About This Ancient Grain

Table of Contents

Spelt is an ancient grain that has been cultivated for thousands of years, offering a distinctive nutty flavor and an impressive nutritional profile that has captured the attention of health-conscious individuals worldwide. For people living with diabetes, understanding how different foods affect blood sugar levels is crucial for effective disease management. As more individuals seek alternatives to modern refined grains, spelt has emerged as a popular option. But is spelt truly a better choice for diabetics? This comprehensive guide explores everything you need to know about spelt and its impact on blood sugar levels, helping you make informed dietary decisions.

What Is Spelt? Understanding This Ancient Grain

Spelt (Triticum spelta), also known as dinkel wheat, is a species of wheat that has been nourishing civilizations since ancient times. Spelt was cultivated from the Neolithic period onward and was a staple food in parts of Europe from the Bronze Age to the Middle Ages. Unlike modern wheat varieties that have been extensively hybridized and modified, spelt has remained relatively unchanged over millennia, earning it the designation as an “ancient grain.”

Like common wheat, spelt is a hexaploid wheat species, which means it has six sets of chromosomes. This genetic complexity contributes to its unique characteristics and nutritional properties. Spelt has a tougher husk, which helps protect the nutrients inside the grain, potentially preserving more of its beneficial compounds compared to modern wheat varieties.

Today, spelt is available in various forms including whole grain berries, flour, flakes, pasta, and bread. Flour made from spelt has a nutty and slightly sweet flavour and the flour can be used in most recipes that contain regular or whole-wheat flour. This versatility makes it an accessible option for those looking to incorporate ancient grains into their diet.

Nutritional Profile of Spelt: A Powerhouse of Nutrients

Understanding the nutritional composition of spelt is essential for diabetics who need to carefully monitor their carbohydrate intake and overall nutrition. Spelt offers an impressive array of nutrients that contribute to overall health.

Macronutrient Breakdown

A 100-gram reference serving of uncooked spelt provides 340 kilocalories of food energy and is a rich source of protein, dietary fiber, several B vitamins, and numerous dietary minerals. Spelt contains about 70% total carbohydrates, including 11% as dietary fibre, and is low in fat.

When examining spelt flour specifically, a 1/4 cup (30 grams) serving contains 110 calories, 0.5g fat, 0mg sodium, 22g carbohydrates, 4g fiber, 0g sugars, and 5g protein. This macronutrient distribution shows that spelt is predominantly a carbohydrate source, which is an important consideration for blood sugar management.

Vitamins and Minerals

Spelt stands out for its exceptional micronutrient content. Highest nutrient contents include manganese (143% DV), phosphorus (57% DV), and niacin (46% DV). Additionally, spelt is an excellent source of calcium, magnesium, selenium, zinc, iron, and manganese, along with vitamin E and B-complex vitamins.

Though it is nutritionally similar to wheat, comparisons have shown it to be slightly higher in zinc and protein. This enhanced nutritional profile makes spelt a nutrient-dense choice compared to refined grains and even some whole wheat products.

Fiber Content and Its Importance

One of spelt’s most significant nutritional advantages is its fiber content. One half cup of cooked spelt contains 5.5 grams of protein and 4 grams of fiber, along with calcium, iron and B vitamins (especially niacin). Fiber plays a crucial role in blood sugar management, making this an especially important component for diabetics.

Fiber helps to slow your digestion, which helps to reduce blood sugar spikes after eating. This slower digestion rate is one of the key mechanisms by which whole grains like spelt can help moderate blood glucose responses compared to refined grain products.

Understanding Glycemic Index and Glycemic Load

Before diving into spelt’s specific impact on blood sugar, it’s important to understand two key concepts: glycemic index (GI) and glycemic load (GL). These measurements help predict how foods will affect blood glucose levels.

What Is Glycemic Index?

The glycemic index is a number from 0 to 100 assigned to a food, with pure glucose arbitrarily given the value of 100, which represents the relative rise in the blood glucose level two hours after consuming that food. A food is considered to have a low GI if it is 55 or less; high GI if 70 or more; and mid-range GI if 56 to 69.

The GI of a specific food depends primarily on the type of carbohydrate it contains, but is also affected by the amount of entrapment of the carbohydrate molecules within the food, the fat, protein content of the food, the moisture and fiber content, the amount of organic acids, and the method of cooking. This complexity means that the same grain can have different GI values depending on how it’s processed and prepared.

Why Glycemic Index Matters for Diabetics

Foods with high glycemic index cause rapid spikes in blood sugar, which can be challenging to manage. For people with diabetes, these rapid spikes can lead to difficulties in maintaining stable blood glucose levels and may contribute to long-term complications. Low-GI foods, such as whole grains, lead to slower, more controlled increases in blood sugar levels, helping in avoiding sudden spikes and dips, making it easier to maintain stable A1C levels.

Spelt’s Glycemic Index: What the Research Shows

The glycemic index of spelt has been the subject of scientific research, and the findings reveal important nuances that diabetics should understand.

Whole Grain Spelt vs. Spelt Flour Products

The form in which spelt is consumed significantly impacts its glycemic response. Uncooked spelt has a glycemic index of 63, which places it in the medium GI category. The glycemic index of spelt flour is estimated to be 55 to 67, according to The Diabetes Council, which means spelt flour has a moderate effect on blood sugar levels.

Interestingly, wholegrain spelt bread has a GI of 54 and a 30g portion has a GL of 7 or 8, which falls into the low GI category. This demonstrates that whole grain spelt products may offer better blood sugar control than refined spelt products.

Spelt Compared to Regular Wheat

One of the most important questions for diabetics is whether spelt offers advantages over regular wheat. Research provides some surprising insights. Results showed that the glycemic profile of spelt white bread was not different from that of wheat white bread (GI of 93 ± 9). This study indicates that when processed into white bread, spelt behaves similarly to conventional wheat in terms of blood sugar impact.

However, spelt flour has a slightly lower glycemic index compared to whole wheat, buckwheat, corn, and millet flours. This suggests that in flour form, spelt may offer modest advantages over some other grain flours, though bread made with spelt flour has a similar glycemic index to bread made with white flour.

A study examining German breads found that wholemeal spelt wheat had a GI of 63 and was classified as medium GI, reinforcing that whole grain spelt products fall into the moderate glycemic category.

The Importance of Processing and Preparation

The research clearly demonstrates that how spelt is processed dramatically affects its impact on blood sugar. Whole grain spelt products consistently show lower glycemic responses than refined spelt products. This aligns with general nutritional principles: Whole grains like spelt have a lower glycemic index compared to refined grains, which helps in moderating blood sugar levels.

Health Benefits of Spelt for Diabetics

Beyond its glycemic properties, spelt offers several health benefits that may be particularly valuable for people managing diabetes.

Fiber and Blood Sugar Control

Spelt is high in fiber and protein, which helps in stabilizing blood sugar levels. The fiber content is particularly important because fiber is essential for a healthy digestive system and consuming fiber-rich foods can slow down the absorption of sugars.

Fiber from whole grains may also help to reduce your risk of developing type 2 diabetes. For those already managing diabetes, this fiber content can be a valuable tool in maintaining more stable blood glucose levels throughout the day.

Cardiovascular Health

Diabetes significantly increases the risk of cardiovascular disease, making heart health a critical concern for diabetics. A diet rich in whole grains has been linked to better cardiovascular health. More specifically, research consistently links higher intakes of whole grains with lower risk of stroke, heart attack, type 2 diabetes, and even some cancers.

Fiber helps lower blood cholesterol levels and helps to reduce blood pressure, another risk factor for heart disease. These cardiovascular benefits make spelt a potentially valuable addition to a heart-healthy diabetic diet.

Weight Management

Maintaining a healthy weight is crucial for diabetes management, and spelt may support weight management efforts. Fiber can help you feel full longer so by consuming more fiber-rich foods, you’re more likely to consume fewer sugar-filled food products.

One study of thousands of American kids and adults found that those who consumed more whole grains also consumed more nutrients overall and had a healthier body weight. This suggests that incorporating whole grain spelt into a balanced diet may support both nutritional adequacy and healthy weight maintenance.

Digestive Health

The fiber and other nutrients in spelt and other whole grains can help to improve the health of the good bacteria that live in your digestive system and may help to reduce inflammation and promote healthy digestion. A healthy gut microbiome is increasingly recognized as important for overall metabolic health, including blood sugar regulation.

Potential Concerns and Considerations

While spelt offers many benefits, there are important considerations and potential drawbacks that diabetics should be aware of before incorporating it into their diet.

Gluten Content

Spelt contains gluten, and is therefore suitable for baking, but this component makes it unsuitable for people with gluten-related disorders, such as celiac disease. In fact, about 80% of the protein in spelt is gluten.

Spelt is fairly high in gluten so it is not appropriate for those who must follow gluten-free diets. For diabetics who also have celiac disease or non-celiac gluten sensitivity, spelt is not a suitable option despite its other nutritional benefits.

FODMAPs and Digestive Sensitivity

Some individuals with diabetes may also experience digestive issues such as irritable bowel syndrome (IBS). Like wheat, spelt contains a significant amount of FODMAPs, which can trigger IBS symptoms in susceptible people. FODMAPs are short-chain carbohydrates that can cause digestive discomfort in sensitive individuals.

However, traditional bread-making with fermentation can reduce FODMAPs, suggesting that traditionally prepared spelt products may be better tolerated than modern quick-rise versions.

Phytic Acid Content

Like modern wheat, spelt contains phytic acid, a compound that can interfere with the absorption of essential nutrients. This is particularly relevant for diabetics who may already be at risk for certain nutrient deficiencies. Sprouting, soaking, or fermenting the grain can help to reduce the phytic acid content, making these preparation methods worth considering.

Still a Carbohydrate-Rich Food

Despite its benefits, it’s crucial to remember that spelt remains a carbohydrate-dense food. Spelt has a moderate glycemic index, meaning it can affect blood sugar levels but not as drastically as refined grains like white bread. However, “moderate” impact still means blood sugar will rise, and portion control remains essential.

Practical Tips for Including Spelt in a Diabetic Diet

If you decide to incorporate spelt into your diabetes management plan, following these evidence-based strategies can help you maximize benefits while minimizing blood sugar spikes.

Choose Whole Grain Forms

The research clearly shows that whole grain spelt products have a more favorable glycemic response than refined versions. Opt for whole spelt berries, whole grain spelt flour, or products explicitly labeled as “whole grain spelt.” Whole grains like spelt have a lower glycemic index compared to refined grains, making them the better choice for blood sugar management.

When shopping, look for products where spelt is listed as “whole grain spelt” or “whole spelt flour” rather than just “spelt flour,” which may be refined. Whole spelt berries can be cooked and used similarly to rice or other whole grains, providing maximum fiber and nutrient content.

Practice Portion Control

Managing portion sizes is critical for diabetics to prevent blood sugar spikes. Even though whole grain spelt has a moderate glycemic index, consuming large portions will still significantly raise blood glucose levels. The number of grams of carbohydrate in a food can have a bigger impact on blood sugar levels than the glycemic index does.

A reasonable portion of cooked spelt berries is typically 1/2 to 3/4 cup, which provides approximately 20-30 grams of carbohydrates. For spelt bread, one to two slices is generally appropriate, depending on your individual carbohydrate targets. Always count the carbohydrates in spelt products as part of your total meal carbohydrate budget.

Combine with Protein and Healthy Fats

Including a mix of protein and fiber-rich foods can also slow down carbohydrate absorption. When eating spelt products, pair them with protein sources like lean meats, fish, eggs, legumes, or dairy products, along with healthy fats from sources like nuts, seeds, avocado, or olive oil.

For example, if having spelt toast for breakfast, top it with avocado and eggs rather than jam. If serving spelt berries as a side dish, include them alongside grilled chicken or fish and plenty of non-starchy vegetables. This balanced approach helps moderate the overall glycemic response of the meal.

Add Non-Starchy Vegetables

Incorporating plenty of non-starchy vegetables with spelt-based meals adds volume, fiber, and nutrients without significantly increasing carbohydrate content. Vegetables like leafy greens, broccoli, cauliflower, peppers, tomatoes, and zucchini can help fill you up while providing additional fiber that further slows digestion and glucose absorption.

Consider making spelt salads with abundant vegetables, or serving spelt pasta with a vegetable-heavy sauce rather than a cream or cheese-based sauce. The more vegetables you include, the lower the overall glycemic load of the meal.

Monitor Your Individual Response

Diabetics should monitor their blood sugar levels when introducing spelt into their diet. Individual responses to foods can vary significantly based on factors like insulin sensitivity, medication regimen, activity level, and overall diet composition.

Test your blood glucose before eating a spelt-containing meal and again 1-2 hours afterward to see how your body responds. Keeping a food diary may also help identify any blood sugar fluctuations related to spelt intake. This personalized data is invaluable for determining whether spelt is a good fit for your individual diabetes management plan.

Consider Preparation Methods

How spelt is prepared can influence its impact on blood sugar. Traditional fermentation methods, such as sourdough preparation, may improve the glycemic response and reduce problematic compounds like phytic acid and FODMAPs. If you enjoy baking, consider making sourdough spelt bread rather than quick-rise versions.

Cooking whole spelt berries until they’re al dente rather than very soft may also result in a slightly lower glycemic response, as the starch remains more resistant to digestion. Cooling cooked spelt and reheating it may increase resistant starch content, potentially offering additional blood sugar benefits.

Time Your Consumption Strategically

Consider when you consume spelt products. Many people with diabetes find that their insulin sensitivity is better earlier in the day, making breakfast or lunch potentially better times to include moderate-GI carbohydrates like spelt. Evening meals might focus more on non-starchy vegetables and protein, with smaller portions of grains if any.

Additionally, consuming spelt products after physical activity, when muscles are more receptive to glucose uptake, may result in a more favorable blood sugar response than eating them during sedentary periods.

Spelt Product Options for Diabetics

Understanding the various forms of spelt available can help you make informed choices about which products to incorporate into your diet.

Whole Spelt Berries

Whole spelt berries are the least processed form of spelt and offer the most fiber and nutrients. They cook quickly and can be prepared like rice or risotto and served as a side dish or in a salad, and cooked spelt can be used in place of rice or pasta in recipes. This form provides maximum nutritional benefits and the most favorable impact on blood sugar.

Whole spelt berries can be used in grain bowls, added to soups and stews, mixed into salads, or served as a side dish. Their chewy texture and nutty flavor make them a satisfying alternative to refined grains.

Whole Grain Spelt Flour

Spelt flour can be used in most recipes that call for white or whole wheat flour. When baking at home, using whole grain spelt flour allows you to control ingredients and avoid added sugars and refined carbohydrates often found in commercial baked goods.

Whole grain spelt flour works well in pancakes, muffins, quick breads, and even some yeast breads. It has a slightly sweeter, nuttier flavor than whole wheat flour, which many people find more palatable. When substituting spelt flour for wheat flour, you may need to adjust liquid amounts slightly, as spelt absorbs moisture differently.

Spelt Bread

When choosing spelt bread, look for products made with 100% whole grain spelt flour. Read labels carefully, as many commercial spelt breads contain a mixture of spelt and refined wheat flour, or may include added sugars. The ingredient list should show “whole grain spelt flour” or “whole spelt flour” as the first ingredient.

Remember that even whole grain spelt bread will raise blood sugar, so portion control remains important. Consider open-faced sandwiches using one slice instead of two, or use spelt bread for toast topped with protein-rich foods rather than as the main component of a meal.

Spelt Pasta

Spelt pasta is available in many shapes and can be a flavorful alternative to regular wheat pasta. As with bread, choose whole grain spelt pasta for maximum fiber and nutritional benefits. Cook pasta al dente rather than very soft, as this results in a lower glycemic response.

Serve spelt pasta with plenty of vegetables and a protein source, and keep portions moderate—typically 1/2 to 3/4 cup of cooked pasta as part of a balanced meal. Consider using spelt pasta in cold pasta salads with vegetables, which may have a slightly lower glycemic impact than hot pasta dishes.

Spelt Flakes and Cereals

Spelt flakes can be used similarly to oatmeal or other hot cereals. They provide a hearty breakfast option that can be topped with nuts, seeds, and a small amount of fruit. Avoid pre-sweetened spelt cereals, which often contain significant added sugars that will spike blood glucose.

When preparing spelt flakes, cook them with water or unsweetened plant milk, and add flavor through cinnamon, vanilla extract, or a small amount of nut butter rather than sugar or honey. Top with protein-rich additions like Greek yogurt or nuts to create a more balanced, blood-sugar-friendly meal.

Comparing Spelt to Other Grain Options

To make the most informed decision about including spelt in your diabetic diet, it’s helpful to understand how it compares to other grain options.

Spelt vs. Modern Wheat

As discussed earlier, the glycemic profile of spelt white bread was not different from that of wheat white bread when both are refined. However, spelt is slightly higher in zinc and protein compared to wheat, offering some nutritional advantages.

The key difference lies in choosing whole grain versions of either grain. Both whole grain spelt and whole grain wheat offer fiber and nutrients that support blood sugar management, though some people find spelt more digestible or prefer its flavor.

Spelt vs. Other Ancient Grains

Other ancient grains like quinoa, amaranth, and farro offer different nutritional profiles and glycemic responses. Quinoa, for example, is a complete protein and has a GI of around 53, similar to whole grain spelt. Quinoa is also naturally gluten-free, making it suitable for those with celiac disease.

Barley is another grain worth considering, as it has one of the lowest glycemic indices among grains (around 28 for pearl barley) and is particularly high in soluble fiber. However, like spelt, barley contains gluten.

The best grain choice depends on individual preferences, tolerances, and blood sugar responses. Variety in grain consumption can provide a broader range of nutrients and prevent dietary monotony.

Spelt vs. Refined Grains

Compared to refined grains like white rice, white bread, and regular pasta, whole grain spelt is clearly the superior choice for blood sugar management. Refined grains have had their fiber and nutrient-rich bran and germ removed, resulting in rapid digestion and blood sugar spikes.

If you’re currently consuming primarily refined grains, switching to whole grain spelt products represents a significant improvement for diabetes management. However, if you’re already consuming whole grain wheat products, the switch to spelt may offer only modest additional benefits.

Working with Healthcare Professionals

While this article provides comprehensive information about spelt and blood sugar management, it’s essential to work with your healthcare team when making dietary changes.

Consulting a Registered Dietitian

A registered dietitian can offer personalized advice, ensuring portion sizes align with individual diabetic management plans. A dietitian specializing in diabetes can help you determine appropriate carbohydrate targets for meals and snacks, and can provide guidance on incorporating spelt in a way that fits your overall dietary pattern.

Dietitians can also help you interpret your blood glucose monitoring data and adjust your diet accordingly. They can provide meal planning strategies, recipe ideas, and ongoing support as you navigate dietary changes.

Medication Considerations

If you take diabetes medications, particularly insulin or medications that increase insulin secretion, dietary changes can affect your medication needs. Introducing new foods or changing portion sizes may require adjustments to medication timing or dosing.

Never adjust medications without consulting your healthcare provider. Keep detailed records of your food intake, blood glucose readings, and any symptoms you experience, and share this information with your doctor or diabetes educator.

Regular Monitoring and Follow-Up

Regular check-ups with your healthcare team are essential for successful diabetes management. These appointments provide opportunities to review your blood glucose patterns, A1C levels, and overall health status. Discuss any dietary changes you’ve made, including the incorporation of spelt, and work together to assess whether these changes are supporting your health goals.

Real-World Experiences with Spelt and Diabetes

While scientific research provides important guidance, real-world experiences can offer additional insights. Some individuals report that homemade spelt breads don’t spike their blood sugar, with one person noting that both they and their diabetic mother experienced no spikes.

However, individual responses vary significantly. What works well for one person may not work as well for another, depending on factors like insulin sensitivity, overall diet, activity level, stress, sleep quality, and medication regimen. This underscores the importance of personal monitoring and working with healthcare professionals to determine what works best for you.

Notice that in each of these meals, spelt is just one component of a balanced plate that includes protein, healthy fats, and plenty of non-starchy vegetables. This approach helps moderate the overall glycemic impact while providing satisfying, nutritious meals.

The Bottom Line: Should Diabetics Eat Spelt?

Yes, people with diabetes can eat spelt, as it provides a moderate glycemic index and is packed with essential nutrients. However, this doesn’t mean spelt is a “free food” or that it won’t affect blood sugar levels. The key is understanding how to incorporate it appropriately into a diabetes management plan.

Spelt offers several advantages over refined grains, including higher fiber content, more vitamins and minerals, and a more moderate impact on blood sugar. Its nutritional profile includes significant fiber content and a relatively low glycemic index, making it a suitable option for managing blood sugar levels when consumed in appropriate portions as part of a balanced diet.

However, spelt is not dramatically different from whole wheat in terms of blood sugar impact, and it’s not suitable for everyone—particularly those with celiac disease, gluten sensitivity, or certain digestive conditions. The form matters significantly: whole grain spelt products offer much better blood sugar control than refined spelt products.

The decision to include spelt in your diet should be based on several factors: your individual blood glucose response (which you can determine through monitoring), your personal preferences, any food sensitivities or allergies, your overall dietary pattern, and guidance from your healthcare team.
