Pumpkin is popularly known as a Halloween decoration or a delicious Thanksgiving pie. Yet it's more than just a symbol of these annual festivities -- it offers a bounty of health benefits that have been celebrated for centuries.
Pumpkin, a type of winter squash, is part of the Cucurbitaceae family. It's native to North America and in the U.S. is sometimes referred to as Cucurbita pepo.
[i] One of the fascinating benefits of
pumpkin is its rich beta-carotene content. Beta-carotene is a carotenoid and antioxidant, a natural plant compound that gives pumpkin its bright orange color.
[ii]
Scientists with the Agricultural Research Service (ARS) have developed an eco-friendly way to measure beta-carotene and other
carotenoids found in pumpkin, showing that pumpkin contains more beta-carotene than many other foods found in your pantry.
[iii] The human body can naturally convert beta-carotene into vitamin A, which promotes vision and skin health, among many perks.
In a 2019 clinical trial conducted by the National Eye Institute called the Age-Related Eye Disease Study (AREDS), high doses of beta-carotene along with
vitamins C and
E were linked to a significantly reduced risk of age-related macular degeneration.
[iv] Here's a rundown of additional wondrous benefits of pumpkin for well-being.
1. Anticancer Effects
A 2016 study suggested that a diet rich in beta-carotene can help suppress prostate
cancer tumors.
[v] A cross-sectional study done on a Japanese population in 2014 also showed that beta-carotene can slow the development of colon cancer. In a separate animal study,
pumpkin seed was found to reduce the risk of colon cancer when consumed in dietary proportions.
[vi]
Pumpkin seed extract also had growth inhibition effects on benign prostate hyperplasia, also known as prostate gland enlargement, and some cancer cell lines, such as prostate, breast and colon.
[vii]
2. Diabetes Support
Research published in 2010 concluded that a mixture of flax and pumpkin seeds supplemented in the diet of
diabetic rats may assist in preventing diabetes and its complications.
[viii]
In a more recent study, published in 2019, a combination of two plant extracts -- one of which was pumpkin polysaccharides -- pushed down blood sugar levels in animal models.
[ix] While further human trials may be needed, the study demonstrated the plant compounds' potential to successfully manage Type 2 diabetes.
3. Wound Healing
Pumpkin seed oil has been tested for wound healing due to its known properties that may aid treatment. Results from one study showed that cold-pressed, excellent-quality pumpkin oil, which has a high content of polyunsaturated fatty acids, tocopherols and sterols, promoted efficient
wound healing in rats.

4. Heart Health and Blood Pressure Regulation
According to a 2017 study involving 2,722 participants, consuming plenty of potassium is an important step to maintaining healthy blood pressure.
[xi] Pumpkin is high in
potassium, containing 394 milligrams per cup.
[xii]
Other research revealed that pumpkin seed oil led to beneficial effects when administered along with an ACE-inhibitor and calcium-channel blocker in treating high blood pressure.
[xiii] Consistent with other outcomes is the conclusion of a 2012 study showing that pumpkin seed oil exhibits antihypertensive and heart-protective effects.
[xiv] The mechanism may involve the generation of nitric oxide.
In female rats in a different study, supplementing with pumpkin seed oil also improved lipid profile and cardiovascular outcomes, specifically lowering systolic and diastolic blood pressures.
