Understanding the Nutritional Differences in Arrowroot
When asking, "is arrowroot high in calories?" the answer depends largely on its form. The fresh tuber is naturally lower in calories than the processed starch or flour. The confusion often stems from comparing the whole root's nutritional information with that of the concentrated, dried powder, which is the most common form sold commercially. A 100-gram portion of the raw root has a modest 65 calories, while the same amount of arrowroot flour contains over five times that amount, around 357 calories.
The Composition of Arrowroot
The reason for this caloric density lies in the processing. The flour is essentially pure starch extracted from the root, which removes much of the water content and concentrates the carbohydrates. This is similar to how cornstarch, which is also a pure starch, is much higher in calories by weight than a whole ear of corn. The caloric makeup of arrowroot comes predominantly from carbohydrates, with a small amount of protein and a negligible amount of fat.
- Carbohydrates: Arrowroot is high in carbohydrates, a significant portion of which is resistant starch. This type of starch is not fully broken down and absorbed by the body in the same way as regular starches. Instead, it behaves like soluble fiber, aiding digestion and contributing to a feeling of fullness, which can be beneficial for weight management.
- Protein: Although not a primary source of protein, arrowroot does contain a higher protein content than some other root vegetables, contributing to satiety.
- Micronutrients: Arrowroot provides valuable micronutrients, including folate (vitamin B9), phosphorus, and iron. Folate is crucial for cell growth and DNA formation, making arrowroot a valuable addition to the diet, especially for pregnant women.
Arrowroot vs. Common Thickeners: A Comparison
Arrowroot is often used as a gluten-free and neutral-tasting alternative to other thickening agents like cornstarch and wheat flour. Here is how they stack up nutritionally and functionally.
| Feature | Arrowroot Powder | Cornstarch | All-Purpose Flour |
|---|---|---|---|
| Calories (per 100g) | ~357 kcal | ~381 kcal (varies slightly) | ~364 kcal (varies slightly) |
| Gluten-Free | Yes | Yes (but check labels for cross-contamination) | No |
| Ideal Use | Thickening acidic sauces, fruit pies, glazes | Thickening sauces, gravies, puddings | Rouxs, gravies, baked goods |
| Thickening Power | Starts thickening at lower temps; can break down under high heat | Strong thickening power, works best when brought to a boil | Needs to be cooked to remove raw taste and activate starch |
| Finish | Clear, glossy sheen | Opaque, sometimes cloudy | Opaque finish |
| Dietary Suitability | Gluten-free, paleo, Whole30 | Generally gluten-free, but derived from grain | Not gluten-free |
Health Benefits Beyond Calories
Beyond its low-calorie status in its raw form, arrowroot offers several health advantages that make it a beneficial dietary component. The resistant starch is especially noteworthy, as it acts as a prebiotic, nourishing the beneficial bacteria in your gut. A healthy gut microbiome is linked to improved digestion, enhanced immunity, and overall well-being.
- Digestive Health: Its high-fiber and resistant starch content can help regulate digestion and may provide relief for issues like diarrhea. It has a long history of use for soothing upset stomachs.
- Weight Management: The feeling of fullness promoted by resistant starch and a higher protein content can help control appetite and curb overeating, potentially assisting with weight loss goals.
- Heart Health: Arrowroot is a good source of potassium, a mineral that helps regulate blood pressure. It can also help lower cholesterol levels by reducing fat absorption in the gut.
- Immunity Boosting: The plant's nutrients, which include B-vitamins, iron, and potassium, support the immune system.
How to Incorporate Arrowroot into Your Diet
Arrowroot powder is a versatile ingredient that can be easily added to many recipes. Always create a slurry by mixing the powder with a small amount of cool liquid before adding it to a hot mixture. This prevents clumping.
- Thickening Sauces and Gravies: Whisk a slurry into a simmering liquid at the end of cooking to prevent the thickening power from being compromised by prolonged high heat.
- Gluten-Free Baking: Combine arrowroot with other gluten-free flours to add a light, tender texture to baked goods.
- Fruit Pies and Desserts: Use it as a thickener in fruit-based recipes, as it maintains its clarity and stands up well to acidic ingredients.
- Crispy Coatings: Dust meats or tofu with arrowroot powder before pan-frying to create a crisp exterior.
- Homemade Ice Cream: Incorporating arrowroot can help prevent large ice crystals from forming, resulting in a smoother texture.
Conclusion
Is arrowroot high in calories? The raw root is relatively low, while the processed powder is more calorically dense but still comparable to other starchy thickeners. The key takeaway is that arrowroot's value isn't just in its calorie count but in its nutritional benefits. It is a highly digestible, gluten-free, and nutrient-rich ingredient, making it a smart choice for those on specific diets or simply looking for healthier alternatives in their cooking. Its resistant starch and fiber content can support weight management and gut health, while its mineral profile benefits overall well-being. When used appropriately as a thickener in small quantities, its caloric impact on a recipe is minimal, making it an excellent pantry staple.

Additional Considerations for Using Arrowroot
While arrowroot is a fantastic addition to many dishes, a few considerations should be kept in mind for optimal results:
- Avoid with Dairy: Arrowroot can create a slimy or stringy texture when combined with dairy products, so it's best to avoid it in creamy sauces or custards.
- Best for Quick Cooking: Since prolonged high heat can cause arrowroot's thickening properties to break down, it's most effective when added toward the end of the cooking process.
- Freezing and Thawing: Unlike cornstarch-based mixtures, those thickened with arrowroot freeze and thaw without breaking down, making it perfect for preparing make-ahead meals and frozen desserts.
Overall, arrowroot is a versatile ingredient that offers a nutritious, gluten-free option for a variety of culinary applications, with a caloric profile that is easily managed in a balanced diet.
A Final Word on Arrowroot's Caloric Impact
Ultimately, whether arrowroot is considered 'high' in calories is a matter of perspective and serving size. A teaspoon of arrowroot powder used to thicken a sauce will contribute only a negligible amount of calories to the overall dish. The concentration of calories in the powdered form is typical of any refined starch, but its beneficial properties, such as resistant starch and easy digestibility, make it a superior choice for many people compared to other thickening options. For those concerned with weight management, focusing on the nutrient density and functional benefits of arrowroot rather than just its raw calorie count is the best approach.
