Taro
Taro is a starchy root vegetable rich in fiber, resistant starch, and micronutrients, commonly used in Asian, Pacific, and Caribbean cuisines. Its nutritional profile supports digestive health due to its prebiotic fiber content.
Also known as: cocoyam, Colocasia esculenta, dasheen, eddo, eddoe

Taro (Colocasia esculenta) is a tropical root vegetable with a starchy, potato-like texture and mild, slightly sweet flavor. Native to Southeast Asia and the Indo-Pacific region, it is a staple food in African, Caribbean, Pacific Islander, and Asian cuisines, consumed boiled, roasted, fried, or ground into flour. The edible corm (underground stem) forms the primary commercial product, though taro leaves are also eaten in some culinary traditions.
One cup of cooked taro (approximately 132 g) contains roughly 187 calories, 45 g carbohydrates, 6.7 g fiber, and 0.6 g protein, according to USDA FoodData Central. Taro has a medium glycemic index (approximately 54–56 depending on preparation and variety). A notable component is resistant starch, which increases upon cooling after cooking and behaves like dietary fiber in the colon. Fermentation of resistant starch by gut bacteria produces short-chain fatty acids—including butyrate, propionate, and acetate—that support colonic health. Some research suggests these metabolites may contribute to improved glycemic response, though direct evidence in humans from taro consumption specifically remains limited. The fiber content and low simple sugar proportion mean taro digests more slowly than white potato.
Blood Sugar and Glycemic Response
Taro's medium glycemic index and resistant starch content result in a slower, more gradual blood glucose rise compared to refined carbohydrates or white potato. Cooling cooked taro further increases resistant starch, which is not absorbed in the small intestine and ferments in the colon. However, taro remains a starchy carbohydrate and should be portion-controlled in diabetes management; it is not a low-glycemic food.
Tolerance and Dietary Considerations
Raw taro contains calcium oxalate crystals that cause oral irritation and must be cooked thoroughly—boiling (and discarding cooking water) is the most effective way to reduce these compounds to safe levels. Cooked taro is well-tolerated by most people and is not a common allergen, though individual sensitivity is possible. Taro is low in sodium and naturally gluten-free. Those with kidney disease should moderate portions due to its potassium content (approximately 639 mg per cooked cup), which is moderate-to-high. The high fiber content means rapid introduction may cause bloating or gas; gradual incorporation is advisable for those unaccustomed to fiber-rich foods.
Frequently Asked Questions
Is taro safe to eat raw?
No. Raw taro contains calcium oxalate crystals that cause burning and irritation in the mouth and throat. Taro must be cooked thoroughly—boiling (and discarding the cooking water), roasting, or steaming significantly reduces these compounds, making taro safe and palatable. Always cook taro before consumption.
Is taro good for blood sugar control?
Taro has a medium glycemic index (approximately 54–56) and contains resistant starch, particularly when cooled after cooking, which results in slower glucose absorption compared to white potato or refined carbs. However, it remains a starchy carbohydrate and should be portion-controlled as part of a balanced meal for those managing diabetes.
Does taro contain allergens?
Taro is not classified as a common allergen and does not contain gluten, nuts, or shellfish. Individual allergic reactions are rare but possible. If you have a documented sensitivity to aroids (the plant family including Colocasia), consult a healthcare provider before consuming taro.
How much taro can I eat?
A standard serving is approximately 1 cup cooked (around 187 calories). Those new to high-fiber foods should introduce taro gradually to avoid bloating or gas. People with kidney disease should limit portions due to its moderate-to-high potassium content; consult a clinician for personalized guidance.
