Is Arrowroot Low in Carbs? A Definitive Nutritional Guide

4 min read

According to nutritional data, arrowroot is a starchy root vegetable, and like many starches, it is quite high in carbohydrates. This guide breaks down the carb content of arrowroot, clarifying how it fits into different dietary plans and offering low-carb alternatives for cooking and baking.

Quick Summary

Arrowroot is not low in carbs, but it can be used in moderation on low-carb diets like keto due to its potency as a thickener. Compare its nutritional profile with other starches and discover how to incorporate it wisely into your recipes.

Key Points

  • High Carbohydrate Content: Arrowroot flour is a high-carb ingredient, with around 85 grams of carbs per 100 grams, but can be used in small portions.

  • Use in Moderation for Low-Carb Diets: Due to its powerful thickening properties, a small amount of arrowroot can be incorporated into low-carb recipes without a major impact on total carb count.

  • Excellent Thickener: Arrowroot is more absorbent than cornstarch, so less is needed to achieve the desired effect, making it a more carb-efficient thickener.

  • Nutrient-Rich Alternative: Unlike refined cornstarch, arrowroot provides beneficial nutrients like folate, iron, and potassium.

  • Better for Low-Heat Cooking: Arrowroot is best for thickening sauces and glazes at low temperatures, as prolonged high heat can cause it to lose its thickening ability.

  • Good for Gluten-Free Diets: Arrowroot is a naturally gluten-free and grain-free starch, making it a suitable thickener for those with celiac disease or gluten sensitivities.

Understanding Arrowroot's Nutritional Profile

Arrowroot is derived from the roots of the Maranta arundinacea plant, which grows in tropical regions. It is most commonly sold as a fine, white powder, also known as arrowroot flour or starch, and is prized for its thickening properties in cooking. While it is gluten-free and easy to digest, its carbohydrate content is a critical consideration for anyone managing their carb intake.

The High-Carb Reality

At first glance, arrowroot's nutritional facts reveal its high carbohydrate concentration. For every 100 grams of arrowroot flour, there are approximately 85 grams of total carbohydrates and 84 grams of net carbs. This makes it a very carb-dense ingredient, similar in carb count to cornstarch. However, context is key. While the raw nutritional information is high, the amount used in recipes is typically very small. Because of its excellent thickening power, a little arrowroot goes a long way, which is why it can be incorporated into certain carb-conscious meal plans.

Key Nutrients in Arrowroot

Beyond just carbs, arrowroot offers a range of beneficial micronutrients, which is an advantage over empty-carb thickeners like cornstarch. These include:

  • Folate (Vitamin B9): Essential for cell growth and DNA formation.
  • Iron: Important for oxygen transport in the blood.
  • Potassium: Helps regulate blood pressure and fluid balance.
  • Prebiotic Fiber: The resistant starch in arrowroot acts as a prebiotic, feeding healthy gut bacteria and potentially boosting immune health.

Arrowroot vs. Common Thickeners: A Carbohydrate Comparison

When you're watching your carb intake, it's helpful to see how arrowroot stacks up against other thickening agents. This table provides a side-by-side comparison per typical serving size.

Ingredient (Flour/Powder) Carbs per tbsp (approx.) Best For Low-Carb Suitability Notes
Arrowroot Powder ~7 grams Soups, sauces, and desserts (at low heat) Usable in small quantities High thickening power means you need less.
Cornstarch ~7 grams Gravies, stir-fries (at high heat) Similar to arrowroot, use sparingly Lacks the extra nutrients found in arrowroot.
Almond Flour ~1.5 grams Baking, breading Excellent A common keto and low-carb baking substitute.
Coconut Flour ~2 grams Baking, adding texture Excellent Very absorbent, requires more liquid in recipes.
Xanthan Gum 0 grams Thickening, stabilizing Perfect A powerful thickener, only a tiny amount is needed.

How to Use Arrowroot in a Low-Carb or Keto Diet

Because of its concentrated nature, arrowroot can still find a place in a carb-restricted diet, as long as it is used strategically and in moderation. The key is portion control, as using just a teaspoon or two for a large batch of food will add minimal carbs per serving.

Tips for using arrowroot conservatively:

  • Create a Slurry: Always mix arrowroot powder with a cold liquid before adding it to a hot sauce or soup. This prevents clumping and ensures a smooth consistency. Since arrowroot breaks down at high temperatures, add it near the end of the cooking process.
  • Use Half as Much: For sauces and gravies, you generally only need about half the amount of arrowroot powder compared to cornstarch to achieve the same thickening effect.
  • Mix with Other Flours: In baking recipes, arrowroot can be combined with other, lower-carb flours like almond or coconut flour to reduce the overall carb count of the final product.
  • Reserve for Specific Dishes: Use arrowroot when a clear, glossy finish is desired for fruit-based sauces or glazes. For creamier soups or dishes, consider other thickeners or a keto-friendly alternative.

Conclusion

In summary, arrowroot is not a low-carb food, but it can be used sparingly and strategically within a low-carb diet. Its high-starch content means it should not be consumed in large quantities by those seeking to minimize their carbohydrate intake. However, its potency as a thickener and its additional nutritional benefits make it a valuable tool when used in the right context. For those on strict ketogenic diets, alternatives like xanthan gum, almond flour, or coconut flour provide much lower-carb options for thickening and baking. By understanding its properties and practicing moderation, you can decide if and how arrowroot fits into your dietary plan.

Alternatives to Arrowroot for Low-Carb Diets

For those on a strict low-carb or keto diet, here are some alternatives that provide thickening power without the carbs:

  • Xanthan Gum: A carbohydrate-free food additive that is a highly effective thickener, used in very small amounts.
  • Guar Gum: Another keto-friendly thickening agent derived from guar beans. It is best for cold dishes.
  • Almond Flour: A popular low-carb flour for baking that can provide bulk and structure to recipes.
  • Coconut Flour: A gluten-free and low-carb flour known for its high fiber content and absorbency.
  • Psyllium Husk Powder: Acts as a binding agent in baking and as a thickener in sauces. Extremely high in fiber.

Key Benefits Beyond Carb Count

Even though arrowroot isn't low-carb, its nutritional profile offers several benefits:

  • Nutrient-Dense: Contains important minerals and B vitamins like folate, iron, and potassium.
  • Digestible: It is known to be gentle on the stomach and easily digestible.
  • Gluten-Free: An excellent alternative for individuals with celiac disease or gluten sensitivity.
  • Prebiotic Properties: The resistant starch in arrowroot can support gut health by feeding beneficial bacteria.

How to Choose the Right Thickener

Choosing the right thickener depends on your recipe and dietary goals. For a small amount of thickening in a low-carb sauce, a tiny bit of arrowroot powder can work well. However, for significant thickening or baking needs, opting for dedicated low-carb alternatives like almond flour or xanthan gum is often the best choice to keep the carbohydrate count down.

Frequently Asked Questions

No, arrowroot flour is not a good low-carb alternative for baking, as it contains a similar amount of carbs to regular flour. For low-carb baking, better options include almond flour or coconut flour.

You can use arrowroot on a keto diet, but only in very small, controlled portions as a thickener, not as a primary flour. Because a little goes a long way, the small amount used adds minimal net carbs.

The total carbohydrate content of arrowroot and cornstarch is very similar per 100 grams. However, arrowroot powder is a more powerful thickener, so you can often use less of it in a recipe, resulting in fewer carbs overall for a given effect.

Both are gluten-free starches used as thickeners, but arrowroot holds up better to freezing and acidic ingredients, while tapioca can get stringy. Tapioca is also more suited for longer cooking times, as prolonged heat can cause arrowroot to break down.

To minimize carb intake, use arrowroot as a thickener, not a flour. Prepare a slurry by mixing a small amount with cold liquid before adding it to hot sauces or stews, and add it at the end of the cooking process.

For thickening, excellent low-carb and keto alternatives include xanthan gum and guar gum. For baking, consider almond flour or coconut flour, which are low in carbs and gluten-free.
