There are roughly 151 calories in one ounce (28 grams) of shell-free pumpkin seeds, mainly from fat and protein.In addition, a 1-oz (28-gram) serving contains (1)

• Fiber: 1.7 grams.
• Carbs: 5 grams.
• Protein: 7 grams.
• Fat: 13 grams (6 of which are omega-6s).
• Vitamin K: 18% of the RDI.
• Phosphorous: 33% of the RDI.
• Manganese: 42% of the RDI.
• Magnesium: 37% of the RDI.
• Iron: 23% of the RDI.
• Zinc: 14% of the RDI.
• Copper: 19% of the RDI.

They also contain lots of antioxidants and a decent amount of polyunsaturated fatty acids, potassium, vitamin B2 (riboflavin) and folate.

Pumpkin seeds and seed oil also contain many other nutrients that have been shown to provide health benefits (2, 3).

Bottom Line: Pumpkin seeds are rich in antioxidants, iron, zinc, magnesium and many other nutrients. An ounce (28 grams) contains about 151 calories.

2. High in Antioxidants

Pumpkin seeds contain antioxidants like carotenoids (the yellow, red, and orange colors in vegetables) and vitamin E.

Antioxidants can reduce inflammation and protect your cells from harmful free radicals. Because of this, consuming foods rich in antioxidants can help protect against many different diseases.

It is thought that the high levels of antioxidants in pumpkins seeds are partly responsible for their positive effects on health.

In one study, inflammation was reduced when rats with arthritis were given pumpkin seed oil. Rats given an anti-inflammatory drug experienced negative side effects, whereas rats given pumpkin seed oil had no side effects.

Bottom Line: Pumpkin seeds are full of antioxidants that may help protect against disease and reduce inflammation.

3. Linked to a Reduced Risk of Certain Cancers

Diets rich in pumpkin seeds have been associated with lower levels of stomach, breast, lung, prostate and colon cancers (5).

A large observational study found that eating them was associated with a reduced risk of breast cancer in postmenopausal women (9).

Others studies suggest that the lignans in pumpkin seeds may play a key role in the prevention and treatment of breast cancer (10). Lignans are special plant chemicals that can help to balance hormones.

Further test-tube studies found that a supplement containing pumpkin seeds had the potential to slow down the growth of prostate cancer cells.

Bottom Line: Some evidence suggests that pumpkin seeds may help to prevent certain cancers.

4. Improve Prostate and Bladder Health

Pumpkin seeds may help relieve symptoms of benign prostatic hyperplasia (BPH), a condition where the prostate gland enlarges and can cause problems with urination.

Several studies in humans found that eating these seeds reduced symptoms that are associated with BPH (13).

A study of over 1,400 men looked at the effects of consuming pumpkin seeds on BPH. After one year, men receiving them reported reduced symptoms and a better quality of life.

There is also research to suggest that taking pumpkin seeds or their products as supplements can help treat symptoms of an overactive bladder.

One study found that taking a supplement of 10 grams of pumpkin seed extract daily improved urinary function in 45 men and women with overactive bladders.

Bottom Line: Pumpkin seeds may reduce symptoms of benign prostate enlargement and an overactive bladder.

5. Very High in Magnesium

Pumpkin seeds are one of the best natural sources of magnesium. This is important, since magnesium deficiency is common in many Western countries.

In the US, around 79% of adults had a magnesium intake below the recommended daily amount.

Magnesium is necessary for more than 600 chemical reactions in the body. Adequate levels of magnesium are important for:

• Controlling blood pressure
• Reducing heart disease risk
• Forming and maintaining healthy bones (19).
• Regulating blood sugar levels

Bottom Line: Pumpkin seeds are a rich source of magnesium. Healthy magnesium levels are important for your blood pressure, heart health, bone health and blood sugar levels.

6. May Improve Heart Health

Pumpkin seeds are a good source of antioxidants, magnesium, zinc and fatty acids, all of which may help keep your heart healthy.

Animal studies have also shown that pumpkin seed oil can help reduce high blood pressure and high cholesterol levels.

These are two important risk factors for heart disease.

A study involving 35 postmenopausal women found that pumpkin seed oil supplements reduced diastolic blood pressure by 7% and increased the “good” HDL cholesterol by 16% over a 12-week period (25).

Other studies suggest that it may be the nitric oxide enzymes contained in pumpkin seed oil that are responsible for its positive effects on heart health.

Nitric oxide helps expand blood vessels, improving blood flow and reducing the risk of plaque growth in the arteries.

Bottom Line: Nutrients in pumpkin seeds may help keep your heart healthy by reducing blood pressure and increasing good cholesterol.

7. Can Lower Blood Sugar Levels

Animal studies have shown that pumpkin, pumpkin seeds, pumpkin seed powder and pumpkin juice can reduce blood sugar.

This is especially important for people with diabetes, who may struggle to control their blood sugar levels.

Several studies have found that supplementing the diet with pumpkin juice or seed powder reduced blood sugar levels in people with type 2 diabetes.

The high magnesium content of pumpkin seeds may be responsible for its positive effect on diabetes.

An observational study involving over 127,000 men and women found that diets rich in magnesium were associated with a 33% lower risk of type 2 diabetes in men and a 34% lower risk in women.

More research is needed to confirm this beneficial effect on blood sugar levels.

Bottom Line: Pumpkin seeds may help reduce blood sugar levels for people with type 2 diabetes. However, more research is needed.

8. Very High in Fiber

Pumpkin seeds are a great source of dietary fiber. Whole seeds provide 5.2 grams of fiber in a single 1-oz (28-gram) serving.

However, pumpkin kernels with the shell removed contain 1.7 grams of fiber per ounce. These are the green pumpkin seeds available in most supermarkets.

A diet high in fiber can promote good digestive health.

In addition, high-fiber diets have been associated with a reduced risk of heart disease, type 2 diabetes and obesity.

Bottom Line: Whole pumpkin seeds are an excellent source of fiber. Diets high in fiber are associated with many health benefits, including a reduced risk of heart disease, diabetes and obesity.

9. May Improve Sperm Quality

Low zinc levels are associated with reduced sperm quality and an increased risk of infertility in men.

Since pumpkin seeds are a rich source of zinc, they may help improve sperm quality.

Evidence from one study in mice suggests they may also help protect human sperm from damage caused by chemotherapy and autoimmune diseases.

Pumpkin seeds are also high in antioxidants and other nutrients that can contribute to healthy testosterone levels and improve overall health.

Together, all these factors may benefit fertility levels and reproductive function, especially in men.

Bottom Line: The high zinc content of pumpkin seeds may help improve sperm quality and fertility in men.

10. May Help Improve Sleep

If you have trouble sleeping, you may want to eat some pumpkin seeds before bed. They’re a natural source of tryptophan, an amino acid that can help promote sleep.

Consuming around 1 gram of tryptophan daily is thought to help improve sleep.

However, you would need to eat around 7 oz (200 grams) of pumpkin seeds to get the necessary 1 gram of tryptophan.

The zinc in these seeds can also help convert tryptophan to serotonin, which is then changed into melatonin, the hormone that regulates your sleep cycle.

In addition, pumpkin seeds are an excellent source of magnesium. Adequate magnesium levels have also been associated with better sleep (34).

Some small studies have found that taking a magnesium supplement improved sleep quality and total sleep time in people with low magnesium levels (35, 36).

Bottom Line: Pumpkin seeds are a good source of tryptophan, zinc and magnesium, all of which help promote good sleep.

11. Easy to Add to Your Diet

If you’d like to experience the benefits of pumpkin seeds, they’re easy to incorporate into your diet.

In many countries, they’re a popular snack that can be eaten either raw or roasted, salted or unsalted.

As well as eating them alone, you can add them to smoothies or to Greek yogurt and fruit.

You could incorporate them into meals by sprinkling them into salads, soups or cereals. Some people use pumpkin seeds in baking, as an ingredient for sweet or savory bread and cakes.

However, as with many seeds and nuts, they contain phytic acid, which can reduce the bioavailability of some nutrients you eat.

If you eat seeds and nuts regularly, you may want to soak or sprout them to reduce the phytic acid content. Roasting them may also help.

Bottom Line: Pumpkin seeds can be easily incorporated into the diet as a snack or as an additional ingredient in meals or baking.

Do Pumpkin Seeds Have Any Other Benefits?

The rich nutrient content of pumpkin seeds means they may provide many other health benefits, such as improved energy, mood and immune function.

Eating them can help solve dietary deficiencies and may protect against various health problems.
