What are the side effects of arrowroot flour?

4 min read

While generally considered safe for consumption in standard food amounts, arrowroot flour can cause side effects, particularly when used in excess or by sensitive individuals. Understanding potential adverse reactions is key to safely incorporating this popular gluten-free thickener into your diet.

Quick Summary

Arrowroot flour is generally safe, but excessive intake may lead to digestive problems like constipation or bloating. Rare allergic reactions can occur, and individuals with diabetes should monitor their blood sugar due to its starch content.

Key Points

  • Digestive Issues: Excessive consumption can cause digestive problems like constipation, bloating, or gas due to its high thickening properties and resistant starch.

  • Rare Allergic Reactions: Although arrowroot is naturally hypoallergenic, rare allergic reactions can occur, with symptoms ranging from mild hives to severe anaphylaxis.

  • Blood Sugar Impact: As a carbohydrate-rich starch, arrowroot can influence blood sugar levels; individuals with diabetes should use it in moderation.

  • Caution for Medicinal Doses: Extremely rare cases of liver issues have been linked to consuming large, concentrated quantities of arrowroot juice, not standard culinary usage.

  • Safe in Moderation: Arrowroot flour is considered safe for most people when consumed in moderate, food-level amounts.

  • Special Populations: Pregnant women, infants, and those with pre-existing conditions like liver disease should consult a doctor before using arrowroot in large doses.

Understanding the Most Common Digestive Side Effects

Arrowroot flour is often prized for being a gentle and easily digestible starch, which is why it is frequently used in baby food and for soothing upset stomachs. However, this is largely dependent on moderation. Excessive consumption can lead to the opposite effect, causing notable gastrointestinal discomfort.

  • Constipation: Due to its powerful thickening and moisture-absorbing properties, consuming too much arrowroot without sufficient fiber and water intake can cause constipation. This is a common issue when it is used in large, medicinal-sized doses rather than small culinary quantities.
  • Bloating and Gas: Some individuals report experiencing increased bloating and gas after consuming large portions of arrowroot flour. This may be linked to its resistant starch content, which acts as a prebiotic and ferments in the large intestine. For many, this is a beneficial process, but in some cases, it can cause discomfort.

Allergic Reactions to Arrowroot

Though rare, allergic reactions to arrowroot can occur. Because arrowroot is a non-grain, hypoallergenic starch, it is often a safe alternative for people with celiac disease or other grain sensitivities. However, as with any food, an individual sensitivity is possible. Reactions can range from mild to severe.

Symptoms of an arrowroot allergy can include:

  • Mild Reactions: Itching or swelling of the mouth, lips, or tongue, hives, and mild stomach upset.
  • Severe Reactions (Anaphylaxis): This is a life-threatening, though extremely uncommon, reaction that requires immediate medical attention. Symptoms include difficulty breathing, significant drops in blood pressure, dizziness, and loss of consciousness.

Considerations for Specific Health Conditions

While arrowroot is generally safe, certain individuals should exercise caution or consult a healthcare provider before use, especially when considering it for therapeutic purposes.

Arrowroot and Blood Sugar

As a pure starch, arrowroot consists almost entirely of carbohydrates. While it contains resistant starch that can have a stabilizing effect, arrowroot does convert to glucose and can impact blood sugar levels. Individuals with diabetes should be mindful of their intake and monitor their blood sugar levels accordingly. The glycemic impact will be much higher when consumed in large quantities as a medicine than in small amounts as a thickening agent.

Potential Liver Issues

There have been isolated case reports of toxic hepatitis linked to consuming arrowroot juice in large, medicinal quantities. It is critical to note that these cases involved concentrated herbal preparations, not the standard culinary use of arrowroot flour. Nevertheless, individuals with pre-existing liver disease should exercise extra caution and consult a doctor before using arrowroot in significant amounts.

Arrowroot Flour vs. Cornstarch: A Comparison

For those wondering if arrowroot is a better choice than other common thickeners, a comparison of potential side effects and health profiles can be helpful.

Feature Arrowroot Flour Cornstarch
Digestibility Highly digestible for most people; gentle on sensitive stomachs. Can be harder for some to digest, especially in larger quantities, leading to bloating.
Allergenic Potential Low allergenic potential; naturally hypoallergenic. Derived from corn, which is a common allergen and can be inflammatory for sensitive individuals.
Processing Generally less processed, especially organic varieties. Often more highly processed and derived from genetically modified (GMO) corn.
Best Use Best added toward the end of cooking, as high heat can reduce its thickening power. Can withstand higher, longer cooking temperatures for thickening sauces and gravies.
Nutritional Value Contains small amounts of B vitamins and minerals like potassium, iron, and folate. Considered a source of empty carbs with little nutritional value.

Minimizing the Risk of Side Effects

To enjoy the benefits of arrowroot flour while minimizing the risk of adverse effects, consider the following best practices:

  • Use in Moderation: For culinary purposes, a little arrowroot goes a long way. Stick to the amounts needed for thickening, rather than consuming it in large doses as a dietary supplement, unless under medical guidance.
  • Stay Hydrated: When using arrowroot as a thickener, ensure adequate fluid intake to prevent potential constipation.
  • Test for Allergies: If you have multiple food sensitivities, start with a very small amount of arrowroot to see how your body reacts.
  • Consult a Professional: If you have an underlying health condition like diabetes or liver disease, or if you are pregnant or breastfeeding, discuss your arrowroot intake with a doctor.
  • Choose High-Quality Brands: Opt for organic, minimally processed arrowroot powder to avoid potential issues with additives or preservatives sometimes found in commercial products.

Conclusion

Arrowroot flour is a versatile and healthy gluten-free alternative for cooking and baking. For the vast majority of people, its use in typical culinary quantities is perfectly safe and can offer digestive benefits. However, like any food or supplement, it is not without potential downsides. Excessive consumption can cause digestive issues, and in very rare cases, allergies or more serious conditions have been reported, primarily linked to concentrated medicinal use. By being mindful of your intake and aware of the potential risks, you can make the most of arrowroot's benefits while staying safe.
