Pumpkin seeds are highly nutritious and rich in antioxidants. Incorporating them into your diet can help address nutritional deficiencies and shield you from various health issues.
While pumpkin seeds may be small, they are packed with valuable nutrients. Consuming even a small amount can provide a significant dose of healthy fats, magnesium, and zinc. They are linked to several health benefits, including improving heart health, prostate health, and protecting against certain types of cancer. Additionally, their rich nutrient content can provide other health advantages, such as enhanced energy, mood, and immune function. Here are ten scientifically proven health benefits of pumpkin seeds:
Rich in valuable nutrients
One ounce (28 grams) of shell-free pumpkin seeds contains approximately 160 calories, primarily from fats and proteins. Additionally, a 28-gram serving contains:
- Carbohydrates: 3g
- Protein: 8.6g
- Fat: 14g
- Fiber: 1.7g
- Manganese: 56% of the recommended daily intake (RDI)
- Copper: 42% RDI
- Magnesium: 40% RDI
- Phosphorus: 28% RDI
- Zinc: 20% RDI
- Iron: 14% RDI
Pumpkin seeds also contain some antioxidants, small amounts of potassium, riboflavin, and folate.
High in antioxidants
Pumpkin seeds are rich in antioxidants like flavonoids and phenolic acids. They also contain small amounts of vitamin E and carotenoids.
Antioxidants can reduce inflammation and protect your cells from harmful free radicals. Therefore, consuming foods rich in antioxidants can help protect against many diseases.
Reducing the risk of certain types of cancer
Some research suggests that pumpkin seeds may contain plant compounds that could help protect against the development of cancer.
An observational study showed that consuming pumpkin seeds was associated with a reduced risk of breast cancer in postmenopausal women.
Furthermore, one study found that pumpkin seed extract has the potential to slow the growth and spread of prostate cancer cells.
Improving prostate and bladder health
Pumpkin seeds can help alleviate symptoms of benign prostatic hyperplasia (BPH), a condition in which the prostate enlarges, causing problems with urination.
Research also shows that taking pumpkin seeds or their products as dietary supplements can help treat overactive bladder symptoms.
Very high in magnesium
Pumpkin seeds are one of the best natural sources of magnesium, a mineral that is often lacking in the diets of many Western populations.
Magnesium is necessary for more than 600 chemical reactions in your body. Adequate levels of magnesium are also important for controlling blood pressure, reducing the risk of heart disease, forming and maintaining healthy bones, and regulating blood sugar levels.
Affecting heart health
Pumpkin seeds are a good source of antioxidants, magnesium, zinc, and unsaturated fats, all of which can help maintain heart health.
Studies in humans and animals have also shown that pumpkin seed oil can lower blood pressure and cholesterol levels, two important risk factors for heart disease.
One study of 35 postmenopausal women found that pumpkin seed oil supplements lowered diastolic blood pressure by 7% and increased levels of HDL (good) cholesterol by 16%.
Other research suggests that pumpkin’s ability to increase the production of nitric oxide in your body may be responsible for its positive effects on heart health.
Nitric oxide helps dilate blood vessels, improving blood flow and reducing the risk of plaque growth in your arteries.
Lowering blood sugar levels
A study in healthy adults found that those who consumed meals containing 65 grams of pumpkin seeds had lower blood sugar levels after a carbohydrate-rich meal.
The high content of magnesium in pumpkin seeds could be responsible for their positive effect on diabetes.
A large study showed that people who consumed the highest amount of magnesium had a 15% lower risk of developing type 2 diabetes than those who consumed the least amount over a 28-year period.
High in fiber
Pumpkin seeds are an excellent source of dietary fiber. Peeled pumpkin seeds contain 1.7g of fiber in a 28-gram serving.
A fiber-rich diet is important for good digestive health. Additionally, a fiber-rich diet is associated with a reduced risk of heart disease, type 2 diabetes, and obesity.
Improving sperm quality
Low levels of zinc are associated with reduced sperm quality and an increased risk of infertility in men.
Since pumpkin seeds are a rich source of zinc, they can improve sperm quality.
Pumpkin seeds are also rich in antioxidants and other nutrients that can contribute to a healthy testosterone level and overall well-being.
Enhancing sleep
If you have trouble sleeping, you might consider consuming a few pumpkin seeds before bed. They are a natural source of tryptophan, an amino acid that can help improve sleep.
However, keep in mind that you would need to consume about 170 grams of pumpkin seeds to achieve the necessary amount of tryptophan.
