Why Should You Eat Pumpkin Seeds?
Pumpkin seeds (Cucurbita pepo L.) are natural reserves of fats and proteins. They are rich in oil (50%) too. Palmitic (≤15%), stearic (≤8%), oleic (≤47%), and linoleic (≤61%) fatty acids make up the oil (1).
Hence, pumpkin seeds fall into the category of nutritious oil seeds, along with sunflower, soybean, safflower, and watermelon seeds (1).
Pumpkin seeds are growing popular as a rich source of nutrition. They are being sold as a snack mixed with various nuts, seeds, and dried fruits.
The high levels of oleic and linoleic fatty acids in pumpkin seeds may reduce the risk of heart diseases. They possess fair amounts of minerals like potassium, magnesium, zinc, manganese, and copper (1), (2).
Moreover, these seeds contain significant amounts of antioxidants in the form of phytochemicals (1), (2).
Studies prove that these elements may combat gastric, breast, lung, and colorectal cancers (1).
Go through the next section to know what pumpkin seeds do to your body. You can also find suitable scientific evidence for these benefits.
How Do Pumpkin Seeds Benefit Your Health?
Pumpkin seeds have antioxidant, anti-inflammatory, antimicrobial, anti-arthritici XA property or a specific drug type that helps relieve arthritic symptoms of the bone and cartilage, like swelling, pain, and stiffness. , and antidiabetic properties. Extensive research also linked the consumption of these seeds to lower the risk of cancer and UTIs.
1. May Possess Anticancer Properties
Folk medicine used pumpkin seed extracts to treat kidney, bladder, and prostate disorders for centuries. The active molecules, like cucurbitin, inhibit the rapid growth of cancer cells (3).
Experimental studies noted about 40-50% of growth inhibition in prostate, breast, and colon cancer cells. This could be due to the presence of estrogen-like molecules (phytoestrogens) in pumpkin seeds (3).
Compounds like lignans and flavones alter the expression of genes mainly involved in the prevention/management of breast and prostate cancers.
2. May Nourish And Repair Skin
Pumpkin seeds and their oil are excellent skin care agents. The bright orange pigment-producing molecules, called carotenoids, have anti-aging effects. They scavenge free radicals that cause premature aging of the skin (4).
Vitamins A and C in the seeds boost the production of collagen. Collagen helps in wound healing and keeps your skin young and wrinkle-free. The oil has omega-3 fatty acids and ß-carotene. These components are potent anti-inflammatory agents (4), (5), (6).
Using pumpkin seed oil as a topical agent can treat acne, blisters, and chronic inflammation of the skin. It also prevents bacterial and fungal infections when used as a scrub, lotion, or when massaged (4).
3. May Prevent Cardiovascular Diseases
Several animal studies demonstrate the positive effects of pumpkin seed supplementation on heart health. Subjects on a high-fat diet showed a significant decrease in the levels of total cholesterol (7).
The seeds could also lower the levels of LDL (bad cholesterol) by about 79% in the subjects. The studies also report a drop in the levels of inflammatory markers like nitric oxide (7).
Adding pumpkin seeds to your diet can prevent cholesterol accumulation and hardening of the blood vessels. This prevents various heart issues like coronary artery disease, stroke, etc. (7)
4. May Improve Prostate Health
Pumpkin seeds have a notable protective effect on the prostate gland. The prostate is said to store minerals, like zinc. These minerals prevent issues like prostate enlargement (hyperplasia) induced by testosterone imbalance (8), (9).
As they contain useful amounts of zinc, these seeds and oil have shown to inhibit prostate enlargement. Lab trials suggest that oil-free pumpkin seeds may help manage benign prostatic hyperplasiai XA medical condition characterized by the enlargement of the prostate gland and surrounding tissues in aging men. (9), (10).
By managing hyperplasia, the male subjects would have less urine retention. This would lessen the risk of urinary tract infections (10).
5. May Treat Urinary Tract Infections (UTIs)
The pumpkin seed oil has been useful to treat urinary disorders, especially in men. It does so by inhibiting issues like prostate enlargement. Clinical trials have proved that this oil is well-tolerated (11).
Large doses of about 500-1000 mg/day did not trigger undesirable effects. In fact, when subjects with overactive bladder were given this dose for 6 and 12 weeks, their urinary function significantly improved (11).
6. May Promote Hair Growth
These seeds contain good amounts of omega-3 fatty acids. Along with other micronutrients, these fatty acids aid in improving the texture of dry and brittle hair. Zinc is another factor that boosts the production of hair proteins. Pumpkin seeds contain zinc in abundance (12).
Twenty four weeks of treatment with pumpkin seed oil increased hair growth by about 40% in men with baldness. This could happen because the seeds have active molecules called phytosterols. They inhibit the enzymes (proteins) that breakdown hair protein and cause hair fall (13), (14).
7. May Help Manage Diabetes
Pumpkin seeds exhibit active antidiabetic effects. They possess phytochemicals, such as flavonoids and saponins, that effectively control blood glucose levels. These molecules prevent the inflammation of insulin-producing pancreatic cells (14), (15).
Animal studies show that a diet rich in flax and pumpkin seeds enhances the antioxidant enzyme activity. In subjects with diabetes, these enzymes rapidly scavenge the free radicals and thus lessen the impact on the kidneys and pancreas (16).
Not just the seeds, pumpkin leaves and pulp have also been identified to possess antidiabetic properties. The fruit contains complex carbohydrates like pectin, which may help regulate your sugar levels (17).
- Pumpkin seeds have high levels of magnesium. Eating them or using the oil may relieve muscle cramps, bone pain, arthritis, and inflammation. This mineral also boosts memory and cognition (18).
- Along with magnesium, pumpkin seeds are also rich in an amino acid called tryptophan. Tryptophan relieves anxiety and promotes sleep. This happens because it triggers the release of a ‘feel-good’ neurotransmitter, serotonin (19).
- These seeds contain high levels of phosphorus. Phosphorus can eliminate the insoluble compounds in food or those accumulated in your body, like calcium oxalate. Thus, consuming pumpkin seeds may help in lowering the risk of bladder stones.
8. May Lower Cholesterol And Risk Of Obesity
High/abnormal lipid levels are linked to cardiovascular diseases, obesity, and even death. Eating foods that control the metabolism, accumulation, and excretion of lipids, like cholesterol, is the easiest way to avoid such disorders.
Pumpkin seeds are rich sources of good fats, fiber, and antioxidants. Along with other plant seeds like flax and purslane, pumpkin seeds can prevent body weight gain and cholesterol accumulation in the liver (20).
The strong anti-obesity effect of these seeds is attributed to the presence of omega-3 fatty acids, phytosterols, vitamin-E derivatives, and ß-carotene. Linoleic, linolenic, and oleic acids help lower blood cholesterol levels (20).
They also maintain kidney and liver functioning in obese/overweight individuals (20).
However, most of the studies have been done on rats, and the dosage for humans may vary.
