Both pumpkins and sweet potatoes are packed with nutrients. Pumpkins have fewer calories and carbs, whereas sweet potatoes provide more fiber, potassium, and beta-carotene. Pumpkins aid in hydration and bolster the immune system, thanks to their high water content and antioxidants, making them ideal for staying full and enhancing your body’s defenses. Sweet potatoes, on the other hand, are richer in nutrients, offering sustained energy and additional benefits for heart and digestive health, making them the healthier choice overall.
As autumn’s star vegetables, pumpkins and sweet potatoes are king and queen. Both are incredibly adaptable and delicious when roasted and added to soups, stews, salads, and pies. Once sliced open, their vibrant hues are strikingly similar. Elizabeth Huggins, a registered dietitian nutritionist at Hilton Head Health Wellness Resort & Spa, explains, “From a culinary standpoint, sweet potatoes and pumpkins share very similar flavor profiles and harmonize with similar ingredients and spices.”
However, when it comes to nutritional value, which one is healthier? We consulted various dietitians and nutritionists to uncover the health benefits and nutritional breakdown of these two vegetables.
Pumpkins are often associated with mouthwatering Thanksgiving pies, but their versatility extends far beyond that. They offer numerous health benefits, which is why they are a favorite.
Pumpkins are rich in both Vitamin A and beta-carotene, which are crucial for maintaining healthy vision and reducing the risk of age-related eye conditions. They also contain antioxidants like lutein and zeaxanthin, which safeguard eye health, according to Martha Theran, a registered dietitian and educator at Pritikin Longevity Center. Vitamin A and beta-carotene are also beneficial for the skin, Theran adds.
Pumpkins, with their high water content, contribute to a feeling of fullness and hydration without adding many calories. “Pumpkin is notably lower in carbohydrates and calories compared to an equal portion of sweet potatoes,” Huggins points out. “What I love about pumpkin is its high nutrient density for such a low-calorie food. A cup contains just about 30 calories but provides over 200% of your daily vitamin A requirements.”
The Vitamin A and C in pumpkins are vital for supporting immune function, Huggins explains. Furthermore, pumpkin contains over 20 carotenoid compounds, including alpha-carotene, which significantly boost the immune system, according to lifestyle medicine physician Dr. Maria Knobel, MD.
Sweet potatoes are a nutritional powerhouse, Theran notes. Similar to pumpkins, they offer many of the same health benefits, including support for eye and skin health, as well as the immune system. They are also incredibly versatile, easily replacing regular potatoes in many recipes. Here are some reasons why you might want to consider swapping them out.
Both pumpkins and sweet potatoes contain fiber, but sweet potatoes have roughly four times the amount of carbohydrates, making them excellent for digestion. “Fiber is essential for regular bowel movements, and the combination of fiber, antioxidants, and phytonutrients supports overall digestive health and a healthy gut microbiome,” Huggins says. Fiber also aids in blood sugar regulation, Theran adds. A medium sweet potato provides about 4 grams of fiber and the full daily requirement of vitamin A, she notes.
The vitamin B6 in sweet potatoes supports brain health, Theran explains. According to the Mayo Clinic, vitamin B6 is crucial for normal brain development and maintaining a healthy nervous and immune system, thanks to its role in synthesizing neurotransmitters, as noted by the Cleveland Clinic. A deficiency in vitamin B6 has been linked to decreased brain function.
So, which fall favorite is the healthier choice? “I wouldn’t say one is healthier than the other—they each have distinct advantages,” Theran says. “Pumpkin is lower in calories and carbs, which can be particularly helpful for weight and blood sugar control. Sweet potatoes offer more fiber and complex carbs, making them great for sustained energy and digestive health.”
Dr. Julie Pollock, a biochemist and chemistry professor at the University of Richmond, explains that sweet potatoes have more calories than pumpkins due to their higher carbohydrate content, including starch, fiber, and protein. However, the calorie content of sweet potatoes should not be a deterrent. “The differences in carbohydrates and calories are not inherently good or bad, but simply something to consider when it comes to portion sizes and their impact on weight and blood sugar management,” Huggins says. And while sweet potatoes have more calories, they also contain more vitamins, Pollock suggests. This could give them an edge.
