Sweet Potato Dominates the Protein Count
When comparing the protein content of pumpkin and sweet potato, the sweet potato is the clear winner. While neither vegetable is considered a high-protein food, sweet potatoes contain roughly 2 grams of protein per 100-gram serving, which is more than double the amount found in the same quantity of cooked pumpkin. In many developing regions, sweet potatoes serve as a vital source of macronutrients, including this modest protein amount. Additionally, a significant portion of sweet potato's protein is comprised of unique compounds called sporamins, which possess antioxidant properties.
Deeper Dive into Macronutrients
Beyond protein, the overall macronutrient makeup of pumpkin and sweet potato differs significantly. Sweet potatoes are denser in nutrients and contain far less water than pumpkin. A 100-gram serving of sweet potato provides around 86-90 calories, primarily from carbohydrates, including natural sugars and starches. In contrast, a 100-gram serving of pumpkin is very low in calories, with only about 20-50 calories, thanks to its high water content of over 90%. This makes pumpkin a lighter choice for those managing their calorie intake.
A Look at Key Vitamins and Minerals
When it comes to micronutrients, both vegetables are nutritional powerhouses, but sweet potatoes tend to offer higher concentrations of several vitamins. Both are famously rich in beta-carotene, which the body converts to Vitamin A. However, sweet potatoes contain approximately three times more Vitamin A than pumpkin per serving. Sweet potatoes also boast substantially higher levels of Vitamin C, B5, and B6. For minerals, sweet potatoes offer more manganese, copper, and potassium, although pumpkin is also a good source of potassium.
Which Has More Protein: A Nutrient Comparison Table
Here is a side-by-side comparison of the nutritional value of cooked pumpkin and sweet potato per 100-gram serving.
| Nutrient (per 100g) | Pumpkin (cooked, mashed) | Sweet Potato (cooked) |
|---|---|---|
| Protein | ~1.16–1.8g | ~1.6–2g |
| Calories | ~20–50 kcal | ~86–90 kcal |
| Carbohydrates | ~5–12g | ~20–21g |
| Fiber | ~1–3g | ~3–4g |
| Vitamin A | High (e.g., 78% RDI per cup) | Very High (e.g., 106% DV per medium potato) |
| Vitamin C | ~11 mg | ~22–25 mg |
Which One Is Right for Your Goals?
Your choice between pumpkin and sweet potato depends on your specific dietary needs. Consider the following:
- For lower calorie and carb intake: Pumpkin is the better choice. Its high water content makes it very filling for a minimal calorie load, which is beneficial for weight management.
- For sustained energy and a nutrient boost: Sweet potatoes are higher in carbs and calories, providing more sustained energy. They also offer a wider range of vitamins and minerals.
- For gut health: Both contain fiber, but sweet potatoes generally provide more, which aids digestion and promotes a healthy gut microbiome.
- For maximum vitamin A: While both are excellent sources, sweet potatoes deliver significantly more beta-carotene, the precursor to Vitamin A.
Choosing Between Two Healthy Options
Ultimately, both pumpkin and sweet potato are extremely healthy additions to any diet, packed with beneficial vitamins, minerals, and antioxidants. The best choice is often a matter of context and preference. Don't be afraid to use them interchangeably in many recipes, or to enjoy both for a more diverse nutrient intake.
As with any food, preparation matters. Baking, boiling, or steaming preserves more nutrients than frying, and avoiding excessive butter or added sugars is key to maximizing their health benefits.

Conclusion
To summarize, sweet potato contains more protein and is a richer source of calories, carbs, fiber, and many vitamins and minerals compared to pumpkin. Pumpkin, while having less protein, is a low-calorie, high-water content alternative that offers excellent hydration and a different set of nutritional benefits. For a protein and nutrient boost, choose sweet potato. For a lighter, lower-calorie option, pumpkin is your best bet. Both deserve a place in a balanced diet for their unique strengths and overall health-promoting properties.
