How To Eat Taro & Enjoy Its Many Benefits

High in Carbohydrates

Taro root is a high-carbohydrate food. A 100-gram serving of taro root contains about 26.46 grams of carbohydrates. For people on a low-carbohydrate diet, this can be a disadvantage.

However, it’s important to note that taro root also contains a significant amount of fiber, which can help slow down the absorption of carbohydrates and prevent blood sugar spikes. Additionally, carbohydrates are essential for providing energy to the body, so they should not be eliminated entirely from the diet.

Contains Oxalates

Taro root contains a high amount of oxalates, which can be a disadvantage for people who are prone to kidney stones. Oxalates bind to calcium and can form crystals that may lead to kidney stones.

To minimize the risk of kidney stones, it’s recommended to consume taro root in moderation and to drink plenty of water to help flush out any excess oxalates.

May Cause Allergic Reactions

Taro root contains proteins that can cause allergic reactions in some people. Allergic reactions to taro root can range from mild symptoms. Allergic reactions to taro root can range from mild symptoms, such as itching and swelling, to more severe reactions, such as difficulty breathing and anaphylaxis.

If you have a history of food allergies, it’s important to be cautious when consuming taro root and to seek medical attention if you experience any allergic symptoms.

Not Suitable for Raw Consumption

Taro root should never be eaten raw, as it contains calcium oxalate crystals that can irritate the mouth and throat. These crystals can cause a tingling or numbing sensation and may even lead to swelling or difficulty breathing.

To avoid these adverse effects, it’s important to cook taro root thoroughly before consumption. Boiling or steaming taro root can help break down the calcium oxalate crystals and make the vegetable safe to eat.

Conclusion

While taro root has many health benefits, it is not without its disadvantages. People on a low-carbohydrate diet or prone to kidney stones may want to consume taro root in moderation. Additionally, those with a history of food allergies should be cautious when consuming taro root.

If you want to enjoy the benefits of taro root without experiencing the adverse effects, it’s important to prepare the vegetable properly and consume it in moderation.

I’m Rebecca Vittetoe, a field agronomist working with farmers through Iowa State University Extension.

Most of my time is not spent in an office—it’s spent in the field. I work directly with farmers, crop scouts, and ag professionals to solve real problems they face every season. From pest pressure to nutrient issues, I focus on what is actually happening in the field—not just what is written in books.

Over the years, I’ve learned that good farming decisions come from a mix of research and real-world experience. That’s what I try to bring into everything I do.

At toagriculture.com, I share simple, practical insights from the field:

What I see in crops during the season
Common mistakes farmers make
What works—and what doesn’t

My focus areas include crop management, pest management, soil health, and cover crops. I’m especially interested in helping farmers improve productivity while keeping their farming systems sustainable.

Agriculture is always changing. My goal is to make that change easier to understand—and easier to apply in the field.
