Both are packed with health benefits, but their effects on blood sugar differ. While pumpkin stands out for its lower carb and calorie content, sweet potatoes shine with their fiber and complex carbs that slow sugar absorption. In the end, the secret isn’t in the type — it’s in how much you eat.
According to a report by Very Well Health, both sweet potatoes and pumpkin can have beneficial effects on blood sugar levels, but they do so in different ways.
Pumpkin contains significantly fewer carbohydrates than sweet potatoes. One cup of pumpkin provides about 8 grams of carbs, compared to 27 grams in a cup of sweet potatoes — making pumpkin a better choice for avoiding rapid blood sugar spikes.
On the other hand, sweet potatoes are an excellent source of dietary fiber, offering around 4 grams per cup. This fiber helps slow down glucose absorption, improving blood sugar control, particularly in people with type 2 diabetes.
The glycemic index (GI) of both pumpkin and sweet potatoes is around 60, which is considered moderate — meaning both can fit well into a balanced diet.
Pumpkin also contains fewer calories than sweet potatoes, making it suitable for those aiming to reduce the risk of high blood sugar or weight gain. Meanwhile, sweet potatoes provide complex carbohydrates like amylopectin, which digest slowly and help promote a longer-lasting feeling of fullness.
Experts agree that portion size is key — even healthy foods can cause spikes in blood sugar when eaten in excess. Pairing sweet potatoes or pumpkin with a source of protein can further help stabilize glucose levels and support better digestion.
