Health benefits of pumpkin seeds

Pumpkin seed consumption has been linked to better metabolic health (assessing indicators such as blood sugar, blood pressure and cholesterol management). A 2018 study found that pumpkin seed consumption helped manage blood sugar after meals. The fiber content in pumpkin seeds may also contribute to their anti-diabetic impact. A 2019 animal study found that pumpkin pulp and seeds helped reduce blood pressure by as much as 20%. Finally, several studies have linked pumpkin seeds (and their oil) to improvements in cardiovascular health. 

Pumpkin seeds may help improve liver health as well. A 2015 study found that replacing saturated fats with healthy fats in pumpkin seeds could help reduce risks associated with non-alcoholic fatty liver disease, including atherosclerosis development. The study also found that the anti-inflammatory effect of pumpkin seed oil provided further benefits.

With their abundant antioxidants and other bioactive compounds, pumpkin seed consumption may also play a role in reducing several cancers. A 2012 study in German women found that increased pumpkin seed consumption could reduce breast cancer risk in post-menopausal women. Some benefits in the study were derived from the phytoestrogens found in pumpkin seeds. Animal studies utilizing pumpkin seeds have also found benefits in lowering the risk of colon cancer.

Pumpkin seeds may be a perfect dietary choice for men as multiple studies have demonstrated the benefits of pumpkin seed consumption and prostate health. A 2016 study found that pumpkin seed oil may play a role in inhibiting the growth of prostate cancer cells. Another study found that pumpkin seed oil was a safe and effective complementary and alternative medicine treatment for men with enlarged prostates without cancer. Pumpkin seeds may help with hair growth as well. A 2014 randomized controlled trial found that men who consumed 400 mg of pumpkin seed oil daily for 24 weeks saw improvements in hair growth.

Studies also show that pumpkin seeds (and their oil) may benefit overactive bladder and may also reduce insomnia due to the seeds’ tryptophan content.

Finally, pumpkin seeds’ soluble fiber and magnesium content may contribute to better gut health.

In addition to physical benefits, pumpkin seeds may contribute to mental health benefits as well. According to studies, their nutrient profile (high in antioxidants, omega-3 fatty acids and magnesium) may serve as a dietary consideration (alongside other therapies) for individuals at risk or suffering from depression, anxiety or stress.
