Pumpkin: Nutrients, What Research Shows and Safety

Pumpkin is the fruit of vining plants in the gourd family (Cucurbitaceae), mainly Cucurbita pepo and Cucurbita maxima. The orange flesh is eaten cooked, in soups, purées and baking, and people eat it for its orange color, which comes from carotenoids (plant pigments the body can turn into vitamin A). This page keeps the whole food apart from supplements and hype, and says plainly what research does and does not show. The seeds have their own pages: pumpkin seeds as a food and pumpkin seed as a herb.

Read this first

• Beta-carotene from food is not the same as beta-carotene pills. In large trials, beta-carotene supplements raised lung cancer risk in smokers and in people exposed to asbestos. [4][5][6] Eating pumpkin is a different thing, but smokers should ask a clinician before taking any beta-carotene or vitamin A supplement.
• Pie filling is not pumpkin. A can labeled pumpkin pie filling or mix contains added sugar and spices, while plain canned pumpkin is cooked pumpkin. Check the ingredient list. [14]
• Potassium: pumpkin has a moderate amount (340 mg per 100 g). [1] People with kidney problems, and people taking ACE inhibitors, ARBs or potassium-sparing diuretics, should ask a clinician about potassium-rich foods. [8]
• Allergy: a food allergy is possible with any food. For trouble breathing or swelling of the face or throat, call 911. See food allergy basics and emergency signs.
• Evidence in one line: pumpkin is a good source of provitamin A and a low-calorie vegetable, but we found no good human trials showing it prevents or treats a disease.

What is in it (USDA values)

Raw pumpkin, USDA FoodData Central item 168448 (SR Legacy). [1] USDA household portion: 1 cup of 1-inch cubes = 116 g. This is information about the food, not a prescription.

% Daily Value uses the FDA 2016 Daily Values; values vary with variety, ripeness and storage. [1]

The main plant compounds USDA measured in raw pumpkin are carotenoids: beta-carotene, alpha-carotene (4,016 µg per 100 g) and lutein with zeaxanthin. [1] The body can convert some carotenoids, such as beta-carotene, into vitamin A. [2][3] Most of the health claims made for pumpkin compounds come from laboratory and animal work. A 2022 review lists many such properties, but we did not find human trials behind most of them. [16]

What research says

Eaten as food vs taken as a supplement or extract. Cooked pumpkin gives vitamin A precursors inside a food that also contains other nutrients. Capsules, powders and extracts are different products. Pumpkin-seed products are covered on the pages linked above. Beta-carotene supplements, not food, were the products that raised lung cancer risk in smokers. [4][5][6] Large amounts of beta-carotene from food can turn the skin yellow or orange (carotenemia), which fades when intake falls and is not described as serious. [2]

How much is a normal serving

• USDA household portion: 1 cup of 1-inch cubes of raw pumpkin is 116 g. [1]
• UK (NHS): 80 g of fresh, canned or frozen vegetables counts as one of your 5 A DAY portions. [11] This is an official figure, not a personal prescription.
• WHO: at least 400 g of fruit and vegetables a day for people older than 10 (fact sheet date 26 January 2026). [12]
• Canned or frozen: the NHS advises choosing canned vegetables with no added salt or sugar. [11] See fresh, frozen and canned produce.
• Plain canned pumpkin versus pie filling: plain canned pumpkin is cooked pumpkin purée; pie filling or pie mix has added sugar and spices on top. [14] We could not read an official source on the exact nutrient differences, so check the nutrition label of the product you buy. We did not find a trusted comparison of vitamin A in canned versus fresh pumpkin: Proper evidence not found in the sources we read.
• Cooking effects on nutrients: we did not read a source on this for pumpkin, so we make no claim.

Safety, allergy and medicines

• Beta-carotene and vitamin A supplements: harmful for lung cancer risk in smokers and in people exposed to asbestos in large trials; see above. [4][5][6] This is about pills, not pumpkin.
• Too much preformed vitamin A: this comes from animal sources and supplements, not from the carotenoids in plants. High intake over many years may weaken bones, and large amounts in pregnancy can cause birth defects. [2][3] Pumpkin does not carry that risk in the same way, but ask a clinician about supplements in pregnancy. See foods in pregnancy: what official bodies advise.
• Orange skin (carotenemia): very high beta-carotene intake can turn the skin yellow or orange; it goes away when intake is reduced and is not described as serious. [2]
• Potassium, kidney disease and medicines: poor kidney function can cause too much potassium in the blood. MedlinePlus says ACE inhibitors, ARBs and potassium-sparing diuretics can also raise potassium, and that people with kidney problems, especially on dialysis, should not eat too many potassium-rich foods. [8] See foods, kidney disease, potassium and oxalates.
• Allergy: any food can cause an allergic reaction. We did not find in the sources we read a statement on how common pumpkin flesh allergy is. For trouble breathing or swelling of the face or throat, call 911.
• Added sugar in pie filling and sweetened products: read the label; added sugar is the main difference from plain pumpkin. [14]
• Blood sugar medicines: a 2026 review suggests pumpkin may help blood sugar in some trials. [7] We did not read a source on interactions with diabetes medicines, so people on them should ask their care team, not change doses on their own.
• Pesticide residues, choking and sulphites: no pumpkin-specific sources were read; no claim made.

Choosing, storing and food safety

• Rinse whole produce under running water, scrub firm-skinned items with a clean brush, and do not use soap or produce wash. Wash before cutting, even if you will not eat the skin. [13]
• Cut away damaged or bruised areas. Refrigerate cut or cooked pumpkin and keep perishable produce at 40°F (4°C) or below. [13]
• Keep produce and its cutting board apart from raw meat, poultry and seafood. [13]
• Home canning of pumpkin has its own food-safety rules; we could not read a current official source for them, so follow your local extension service, not a blog.
