Taro (Colocasia esculenta) is an ancient root crop that has fed communities across the Pacific, Asia and Africa for thousands of years. Today it’s enjoying a comeback among people who want a nourishing, minimally processed source of carbohydrates and fiber — especially if you’re looking for alternatives to refined starches that support steady energy, gut health, and nutrient diversity. plants.usda.gov
Quick nutrition snapshot
Cooked taro is mainly a starchy carbohydrate, but it contributes meaningful amounts of fiber and minerals per serving. Typical values for cooked taro (per ~100 g) are roughly:
-
Calories: ~110–140 kcal
-
Carbohydrates: ~26–35 g
-
Dietary fiber: ~4–6 g
-
Potassium: several hundred mg (often cited as ~400–600 mg per 100 g, making taro a good potassium source)
-
Small amounts of vitamin C, B6, magnesium, manganese and trace minerals. Food Struct+1
Those fiber and potassium contents are what make taro nutritionally notable compared with many refined starches. dietaryguidelines.gov
What the science says — benefits backed by research
1. Gut health and resistant starch
Taro contains resistant starch and other fermentable fibers that act as prebiotics — food for beneficial gut bacteria. When microbes ferment resistant starch they produce short-chain fatty acids (SCFAs) such as butyrate, which support colon cell health and may lower intestinal inflammation. Recent lab and animal work, and emerging human studies, point to taro’s potential to increase butyrate-producing bacteria and to modulate gut microbiota in ways that support digestive comfort. PMC+1
2. More stable blood sugar response
Because of its fiber and resistant starch, taro is digested more slowly than simple starches, which tends to blunt post-meal glucose spikes. This does not mean taro is “low-carb” — but replacing refined white bread or highly processed potatoes with taro (and using sensible portion sizes and cooking methods) can help reduce rapid blood sugar rises. (Individual responses vary with portion size, cooking, and what else you eat.) PMC+1
3. Heart health: potassium and blood pressure
Taro is relatively rich in potassium, a mineral that helps the body excrete sodium and relax blood vessels. High-quality reviews and meta-analyses show that increasing dietary potassium from food sources lowers blood pressure, especially in people with hypertension — and is associated with a lower risk of stroke. For people with normal kidney function, choosing potassium-rich whole foods is a heart-healthy strategy. bmj.com+1
4. Antioxidants in purple varieties
Purple-fleshed taro contains anthocyanins and other polyphenols (the pigments that give berries and some potatoes their color). Anthocyanins have been associated with antioxidant and anti-inflammatory effects in lab and clinical studies, and may contribute to vascular and metabolic benefits when included regularly in a varied diet.

Safety note: cook taro thoroughly
Raw taro contains needle-like calcium oxalate crystals that can irritate skin and throat. Proper cooking (boiling, steaming, or long simmering) and sometimes soaking will greatly reduce soluble oxalates and remove the itchy hazard. Studies show extended boiling/steaming reduces the soluble oxalate content substantially; leaves and petioles often require similar treatment if eaten. People with a history of kidney stones or impaired renal function should discuss oxalate and potassium intake with their clinician. PMC+1
Choosing, storing and preparing taro
-
Select firm, heavy corms with no soft spots or mold.
-
Store in a cool, dark place for up to about a week (don’t refrigerate raw corms for long periods). plants.usda.gov
-
Peel under running water to reduce stickiness, then boil or steam 20–40 minutes until tender. For most recipes, cooking fully makes the texture pleasant and neutralizes irritants. spice.alibaba.com
How to use taro (practical ideas)
-
Mash boiled taro with a splash of olive oil and herbs as you would mashed potato.
-
Cube and roast or add to soups and stews for texture and body.
-
Make classic poi (mashed, fermented taro) or use cooked taro in curries, pancakes or flatbreads.
-
For a lower post-meal glycemic effect, pair taro with protein, healthy fat, and non-starchy vegetables. Food Struct
Taro vs common alternatives
-
Compared with white potatoes and white rice, taro often supplies more fiber and resistant starch per serving, which can give a gentler glycemic response. That said, sweet potatoes and some potato varieties may have similar or lower glycemic responses depending on the variety and cooking method. Always consider portion size and how the food is cooked.

Practical daily plan (example)
If you’d like to try taro regularly, a modest approach is to include ½–1 cup of cooked taro 2–4 times per week — paired with vegetables and a source of protein — and watch for improvements in digestion and steady energy. Keep expectations realistic: diet-wide changes (more fiber, more whole plant foods, less processed sugar) are what produce the largest health benefits over time. Food Struct+1
Final takeaway
Taro is not a magic bullet, but it’s a time-tested, nutrient-rich starch with real benefits: prebiotic resistant starch for the gut, useful fiber, a generous potassium contribution for heart health, and antioxidant pigments in purple varieties. Cook it properly, combine it with balanced meals, and it can be a useful, flavorful addition to any modern pantry.
