The Dual Identity of 'Kanda': Yam vs. Onion
In many parts of India, the term "kanda" is used regionally to refer to different vegetables. While in some areas it refers to the common onion, in others, particularly in South and West India, it denotes the elephant foot yam, also known as suran or jimikand. Given the extensive medicinal and nutritional properties attributed to the tuber, this article primarily focuses on the elephant foot yam, while also acknowledging the benefits of onions where relevant.
Kanda: A Nutrient-Dense Tuber
Elephant foot yam (kanda) is celebrated for its impressive nutritional profile. It is a dense source of energy, carbohydrates, and dietary fiber, but contains minimal fat, making it an excellent addition to a balanced diet. A 100g serving of raw elephant foot yam contains a variety of vitamins and minerals crucial for bodily functions.
Essential Nutrients in Elephant Foot Yam
- Vitamins: Rich in Vitamin A and Vitamin C, which act as powerful antioxidants and support immune function. It also provides Vitamin B6, essential for metabolism and red blood cell formation.
- Minerals: A good source of potassium, phosphorous, magnesium, and calcium, vital for bone health, electrolyte balance, and nerve function.
- Fiber: The high fiber content is key to its many health benefits, particularly for digestive health and weight management.
- Omega-3 Fatty Acids: Contains essential fatty acids that help increase good cholesterol and lower bad cholesterol.
Proven Health Benefits of Kanda
Scientific and traditional medicine recognize several benefits of incorporating elephant foot yam into one's diet:
- Improves Digestive Health: The high fiber content acts as a natural probiotic, feeding beneficial gut bacteria and promoting healthy bowel movements. This can help prevent issues like constipation and hemorrhoids.
- Manages Blood Sugar: With a low glycemic index, kanda causes a slow release of sugar into the bloodstream, helping to regulate blood glucose levels. This makes it a suitable food for individuals managing diabetes.
- Boosts Heart Health: The presence of Omega-3 fatty acids helps lower LDL (bad) cholesterol and increase HDL (good) cholesterol. Additionally, its anti-inflammatory properties and potassium content support healthy blood pressure.
- Provides Antioxidant Support: Loaded with flavonoids, phenols, and Vitamin C, kanda helps combat oxidative stress and free radical damage, slowing down the aging process and reducing inflammation.
- Aids in Weight Management: The combination of high fiber and low-fat content promotes a feeling of fullness, which can reduce overall calorie intake and assist in weight loss efforts.
- Maintains Hormonal Balance: Bioactive compounds in elephant foot yam can help maintain hormonal balance in women, potentially alleviating symptoms of PMS and menopause.
- Supports Brain Function: Essential minerals and Omega-3 fatty acids contribute to improved cognitive function, memory, focus, and concentration.

How to Safely Incorporate Kanda into Your Diet
To avoid irritation from calcium oxalate crystals, it is essential to prepare kanda correctly. Soaking peeled and chopped yam in tamarind water, vinegar, or lemon juice for 15–20 minutes before cooking helps neutralize these irritants. It can then be boiled, steamed, fried, or added to curries.
