Nutritional Breakdown: The Raw Numbers
At a glance, swede presents a strong case for weight management due to its lower energy density. A 100g serving of boiled swede contains around 11 kcal, while the same serving of boiled potato (without skin) contains approximately 87 kcal. This caloric difference stems primarily from their carbohydrate profiles. Boiled swede has about 2.3g of carbohydrates per 100g, compared to a potato's 20.1g. For those looking to reduce their carb intake, swapping potato for swede is an effective strategy.
Swede's Nutritional Profile
- High in Vitamins: Swede is an excellent source of Vitamin C, with 100g providing a significant portion of your daily recommended intake. It is also a good source of Vitamin K, Vitamin E, and several B vitamins, including B6.
- Rich in Minerals: This root vegetable contains an impressive array of minerals essential for health, including potassium, calcium, magnesium, manganese, and zinc, which are vital for strong bones and proper muscle function.
- Antioxidants and Phytonutrients: As a cruciferous vegetable, swede is rich in glucosinolates and carotene, antioxidants that fight free radicals and may lower inflammation and the risk of certain cancers.
Potato's Nutritional Profile
- Good Source of Vitamin C and Potassium: Potatoes are well-known for being a fantastic source of potassium, containing more than a banana per serving. They are also high in Vitamin C, which is a powerful antioxidant.
- B Vitamins and Minerals: Potatoes provide a range of B vitamins, including B6, and minerals such as iron and magnesium.
- Resistant Starch: When potatoes are cooked and then cooled, they produce resistant starch. This type of fiber functions as a prebiotic, feeding beneficial gut bacteria and improving gut health.
Glycemic Index: Blood Sugar Impact
The glycemic index (GI) measures how quickly a food raises blood sugar levels. For individuals with diabetes or those monitoring blood sugar, this is a crucial factor. On average, boiled potato has a GI of 78, which is considered high. In contrast, swede's GI is around 72, which is slightly lower. The GI of potatoes, however, is highly influenced by cooking method. For example, chilling a potato after cooking can increase its resistant starch content and lower its GI significantly.
The Cooking Factor: How Preparation Matters
No matter which vegetable you choose, the way it is cooked profoundly impacts its nutritional value. Frying either vegetable, especially deep-frying, adds a large amount of unhealthy fats and calories, negating their inherent health benefits. Boiling, steaming, and roasting with minimal, healthy oil are the best ways to prepare both swede and potato to preserve their nutrients and keep calorie counts low. For potatoes, cooking with the skin on increases fiber content.
Potato vs. Swede: A Comparison Table
| Feature | Potato | Swede | Winner for... |
|---|---|---|---|
| Calories (per 100g, boiled) | ~87 kcal | ~11 kcal | Weight loss |
| Carbohydrates (per 100g, boiled) | ~20.1g | ~2.3g | Low-carb diets |
| Glycemic Index (GI) | ~78 (can vary greatly) | ~72 | Managing blood sugar |
| Protein (per 100g, boiled) | ~1.9g | ~0.3g | Protein intake |
| Fibre | Good source, especially with skin | Good source | Tied |
| Vitamin C | Excellent source | Excellent source | Tied |
| Potassium | More than a banana | Good source | Electrolyte balance |
| Unique Benefits | Resistant starch (when cooled) | Glucosinolates (anti-inflammatory) | Gut health (Potato) / Anti-inflammatory (Swede) |
Which Vegetable is Right for You?
Choosing between swede and potato isn't a simple 'winner takes all' decision. Instead, it's about aligning the vegetable's benefits with your specific health goals.
- For Weight Loss: If your primary goal is to reduce overall calorie and carbohydrate intake, swede is the clear winner. It provides a high volume of food with fewer calories, promoting satiety.
- For Diabetics or Blood Sugar Management: Swede's lower carbohydrate content and generally lower GI make it a safer and more manageable option for controlling blood sugar spikes. However, preparing potatoes in ways that lower their GI, such as boiling and cooling, can make them a viable option as well.
- For Energy and Performance: Athletes or those requiring sustained energy might prefer potatoes. Their higher carbohydrate content makes them a more energy-dense fuel source.
- For Overall Gut Health: Both are beneficial, but in different ways. Potato offers resistant starch for prebiotic benefits, while swede provides dietary fiber. Incorporating both offers a broader spectrum of fiber types.
- For Anti-Inflammatory Benefits: Swede's unique phytonutrients, specifically glucosinolates, offer potential anti-inflammatory advantages.
Understanding the various nutrient profiles allows for informed decisions based on individual needs, rather than viewing one as definitively superior to the other.

Conclusion: No Clear Winner, Only Better Choices
Ultimately, the question of which is healthier, potato or swede, has no single answer. Both are nutrient-dense root vegetables that offer a range of vitamins, minerals, and fiber. The best choice depends on your specific health objectives, such as weight management, blood sugar control, or sustained energy. Swede is the lower-calorie and lower-carb option, making it an excellent choice for those focusing on weight loss or managing diabetes. However, potatoes provide more energy, protein, and a unique form of resistant starch when prepared correctly. The key to maximizing the health benefits of either vegetable lies in your cooking method, favoring boiling, steaming, or roasting over frying. Incorporating both into a balanced diet, prepared healthfully, ensures a diverse intake of beneficial nutrients.
