As the air turns cooler, our plates welcome hearty, seasonal foods. Among the favourites are the comforting sweet potato, or 'shakarkandi', and the unique chestnut. Both are delicious, but which one is nutritionally superior? Let's break it down.
The Calorie and Carb Equation
When
it comes to energy, there's a clear difference. Chestnuts are more calorie-dense, with around 245 calories per 100 grams, compared to sweet potatoes, which contain about 86-112 calories for the same amount. This makes sweet potatoes a lighter option if you're managing weight. Most of these calories come from carbohydrates. Chestnuts have a higher carb count, but they are complex carbohydrates that provide sustained energy. Sweet potatoes also offer complex carbs that are released steadily into the bloodstream, making them a good source of fuel.
A Tale of Two Fibres
Fibre is crucial for digestive health, and both foods are good sources. Chestnuts slightly edge out sweet potatoes here, offering more dietary fibre per serving. Fibre helps you feel full, aids regular bowel movements, and supports the growth of healthy gut bacteria. The fibre in both chestnuts and sweet potatoes also plays a role in slowing down the absorption of sugar, which can help manage blood sugar levels.
The Vitamin and Mineral Powerhouses
This is where their unique strengths really shine. Sweet potatoes are famous for being an incredible source of Vitamin A, primarily in the form of beta-carotene. A single medium sweet potato can provide well over the daily recommended intake, which is essential for vision, immune function, and skin health. On the other hand, chestnuts are unique among nuts for their significant Vitamin C content, an antioxidant that supports the immune system. Chestnuts are also a good source of B vitamins, copper, and manganese, which are important for energy production and bone health. Both contain a good amount of potassium, a mineral that helps regulate blood pressure and supports heart health.
Impact on Blood Sugar
For those managing blood sugar, the glycemic index (GI) is an important consideration. The GI of sweet potatoes can vary significantly depending on how they are cooked. Boiled sweet potatoes have a low-to-medium GI (around 46–61), while baking or roasting can increase it to a high level (up to 94). This is because boiling helps retain a type of fibre called resistant starch, which has less impact on blood sugar. Chestnuts are considered a low–GI food, as their fibre content helps slow the absorption of their carbohydrates, promoting better blood sugar control.
Which One Should You Choose?
The better choice truly depends on your individual needs. Choose sweet potatoes if: Your priority is boosting your Vitamin A intake, you want a lower–calorie carbohydrate source, or you need a versatile vegetable for both savoury and sweet dishes. In India, shakarkandi is famously roasted and enjoyed as a street–side 'chaat', but it's also used in curries, tikkis, and even desserts like kheer. Choose chestnuts if: You're looking for a low–fat, gluten–free nut that is surprisingly high in Vitamin C and fibre. They are also great if you need a source of B vitamins. While less common in everyday Indian cooking than in Europe, chestnuts can be used in pulaos, stuffings, and can be ground into a flour. Their texture is often compared to a baked potato.
