Pumpkin
Pumpkin is a low-calorie, orange winter squash rich in beta-carotene and fiber. It contributes vitamins, minerals, and plant compounds with minimal caloric density in its unsweetened form.
Also known as: Cucurbita pepo, Cucurbita moschata, winter squash, pumpkin purée, pepitas (pumpkin seeds)

Pumpkin (Cucurbita pepo and related species including Cucurbita moschata) is a member of the gourd family, native to North America and now cultivated globally. The edible flesh is commonly used in soups, purées, baked goods, and as a pie filling. Raw pumpkin is approximately 90% water by weight; canned pumpkin purée (without added sugar) is a concentrated, cooked form with a lower water content, meaning nutrient density per gram is somewhat higher. Pumpkin seeds (pepitas) are also consumed as a nutritious snack.
One cup of cooked pumpkin (245 g) provides approximately 49 calories, 2 g protein, 12 g carbohydrate (including 2.7 g fiber), and negligible fat. The carbohydrate is primarily starch and simple sugars. Pumpkin's most notable nutrient is beta-carotene (a provitamin A compound), supplying roughly 200% of the Daily Value per cooked cup. It also contains vitamin C, potassium, manganese, and folate. The fiber content includes both soluble and insoluble forms and supports normal bowel function and may promote satiety, though the effect is modest compared to whole grains or legumes.
Blood Sugar and Glycemic Response
Boiled pumpkin has a high glycemic index (GI ~75) by standard classification (high GI ≥70). However, glycemic index alone does not fully predict blood glucose response. A typical serving (1 cup cooked, 12 g carbohydrate) has a low glycemic load (GL ≈9), which better reflects the actual blood sugar impact of a realistic portion. This means a standard serving as part of a mixed meal is unlikely to cause a pronounced blood glucose spike in most people. Individuals with diabetes should account for the carbohydrate content as usual. Canned pumpkin pie filling contains added sugar and should be distinguished from unsweetened purée.
Tolerance and Intake Considerations
Pumpkin is well tolerated by most adults and children. It is not a common allergen, though oral allergy syndrome has been reported in people with birch pollen allergy. No established upper intake limit exists. Typical portions range from 1/2 to 1 cup of cooked purée or seeds. According to Monash University FODMAP testing, only small serving sizes of pumpkin are classified as low-FODMAP (for example, around 45 g of butternut pumpkin or 75 g of Kent/Japanese/Kabocha pumpkin). Larger portions, including typical serving sizes of 1/2 to 1 cup, are considered moderate to high FODMAP and may trigger symptoms in individuals with irritable bowel syndrome. Pumpkin seeds are calorie-dense and relatively high in omega-6 polyunsaturated fat, which should be considered in portion planning.
Frequently Asked Questions
Is canned pumpkin purée as nutritious as fresh pumpkin?
Canned unsweetened pumpkin purée is a nutritious option comparable to cooked fresh pumpkin. Because canning involves cooking and concentrating the flesh (lower water content), nutrient density per gram is slightly higher in canned purée, but on a typical serving basis the values are similar. Note that some canned products are pumpkin pie filling with added sugar — check the label to confirm you are buying plain unsweetened purée.
Are pumpkin seeds a good source of protein?
Pumpkin seeds contain about 9 g protein per ounce, making them a reasonable plant-based protein source. However, they are calorie-dense and should be portion-controlled. They complement but are not a substitute for dedicated protein foods such as legumes, fish, eggs, or poultry.
Can pumpkin cause digestive upset?
Pumpkin is generally well tolerated. However, according to Monash University, only small serving sizes are classified as low-FODMAP (for example, around 45 g of butternut pumpkin or 75 g of Kent/Japanese/Kabocha pumpkin). Standard serving sizes of around 1/2 to 1 cup cooked are considered moderate to high FODMAP and may cause bloating or other digestive symptoms in sensitive individuals, including many with irritable bowel syndrome. Pumpkin seeds in excess may also cause digestive discomfort. Those managing IBS through a low-FODMAP diet should stick to small portions.
