Health Benefits of Pumpkin Seeds

  Health Benefits of Pumpkin Seeds         

Pumpkin seeds are edible seeds from pumpkins and other varieties of gourd squash. The seeds are cream coloured, flat and oval with a nutty, slightly sweet flavour. They are roasted, salted and eaten as a snack in many parts of the world. You can scoop seeds out of a carving pumpkin and roast them yourself or buy roasted pumpkin seeds from a grocery or health food store. You may see them labelled "pepitas." Pumpkin seeds and pepitas are basically the same thing except that pepitas have their cream-colored shells (hulls) removed and they come from specific varieties of pumpkin. Pumpkin seeds' benefits can include helping you get a good night's rest or supporting the efficiency of different bodily functions. Pumpkin seeds also provide antioxidants, fibre, healthy fats, magnesium, protein and more. You can enjoy pumpkin seeds as a snack or in a variety of recipes, such as pumpkin seed butter, protein powder and tofu. Pumpkins are native to Central and South America, and have been used by Native Americans for centuries as food, as well as medicine. Pumpkin seeds are filled with nutrients, such as unsaturated fats like omega-3s and minerals like magnesium. Because they are so nutritious, pumpkin seeds have a long history of use dating back to the Oaxaca Highlands of Mexico over 7,500 years ago. Across many cultures. Given below are the nutrition and health benefits of pumpkin seeds.

Pumpkin seeds are a source of magnesium. This mineral plays an essential role in more than 300 reactions in your body, including:-

Keeping your heartbeat steady

Maintaining nerve and muscle function

Managing blood sugar

Producing energy

Strengthening bones

Supporting a healthy immune system

Pumpkin seeds have been used as a folk remedy to treat:-

Urinary tract and bladder infections

High blood pressure and blood sugar

Kidney stones

Parasites like intestinal worms

Pumpkin seed oil

Pumpkin seed oil is either steam distilled or cold pressed from pumpkin seeds. It's a dark green oil that's a rich source of polyunsaturated fats and antioxidants (substances that fight cell damage), such as polyphenols and carotenoids. You can use it for cooking, baking, as well as in marinades and salad dressings. Or, you can find it as capsules to take as a supplement or serum to put on your skin or hair. 

Healthy heart function

Pumpkin seeds provide more fat than carbs and protein per one-ounce serving, or about one-quarter of a cup. The fat in pumpkin seeds is mostly monounsaturated and polyunsaturated fat. These healthy fats reduce LDL ("bad") cholesterol levels, which helps lower your risk of heart disease and stroke. The high magnesium content in pumpkin seeds helps lower your blood pressure and keep it steady. Thanks to this effect, diets high in magnesium are linked to a lower risk of stroke and death from heart disease. Studies show that the antioxidants in pumpkin seeds also increase nitric oxide levels in your body. This molecule works to keep your blood vessels smooth, flexible, and healthy, improving blood flow and reducing the risk of heart and circulation problems. A one-ounce serving of unsalted pumpkin seeds without their shells also supplies 1.84 grams (g) of fibre. Experts advise that females eat 25g of fibre per day and males eat 38g per day. Fibre aids in digestion and helps you feel full for long periods. Soluble fibre, the type in pumpkin seeds, might protect against heart disease.

Anti-inflammatory effects

Pumpkin seeds are rich in many antioxidants, which protect your cells from disease-causing damage and reduce inflammation in your body. When they have their hulls, they’re also a great source of dietary fibre, which can boost this effect. Studies show that anti-inflammatory foods can help you prevent chronic diseases, such as type 2 diabetes and heart disease.

Might Increase Male Fertility

Some evidence suggests that pumpkin seeds help improve aspects of male fertility. Research has shown that zinc deficiency may impair sperm quality and the development of sperm cells. Pumpkin seeds are a source of zinc, with about 2.17 milligrams (mg) per one-ounce serving. A study in mice that had lost the ability to produce sperm due to treatment with a chemotherapy drug showed that pumpkin seeds helped restore their ability to make sperm. The mice ate 200 milligrams of pumpkin seed extract per kg of body weight every day for 40 days. Researchers think that the antioxidants in the seeds helped prevent some of the damage from the chemotherapy drug. These results are promising as a way to help people who take chemotherapy keep their fertility. But more research is needed to see if it will work this way in people.

Improved prostate health

Several studies have shown that pumpkin seeds may help ease the symptoms of benign prostatic hyperplasia (BPH). BPH is a condition where your prostate gland is swollen. This can cause it to press against your urethra and irritate your bladder. People with BPH may feel as if they have to pee all the time or they may be unable to completely empty their bladder. But medicines that treat BPH, such as alpha-blockers and 5-alpha-reductase inhibitors (5ARIs), can have side effects like sexual function disorders which may not go away even if you stop taking the medicine. One study included 130 people assigned male at birth (AMAB). This study showed that 500 milligrams of pumpkin seed extract twice a day reduced lower urinary tract symptoms from BPH and improved overall quality of life. 

Anti-cancer properties

Phytoestrogens are natural compounds found in some foods, including pumpkin seeds. The compounds are similar to the hormone estrogen. Some evidence has suggested that consuming foods which contain phytoestrogens helps reduce breast cancer risk. Laboratory studies show that pumpkin seeds can stop the growth of breast and prostate cancer cells. They may also kill cancer cells by triggering them to apoptosis, or cancer cell death. Researchers think that the anti-cancer activity of pumpkin seeds may be due to the high antioxidant levels in the seeds. Pumpkin seeds are a rich source of protein, unsaturated fatty acids, vitamins, and minerals that may reduce your risk of getting chronic diseases, such as cancer. But more research is needed to see how pumpkin seeds work in people to stop cancer cells from growing or to kill cancer cells.

 

Ease the symptoms of overactive bladder

A couple of studies have shown that pumpkin seed oil can improve the symptoms of overactive bladder. Overactive bladder makes you need to pee suddenly and often. Some people may need to get up from bed to pee several times at night. In one study, 45 people with overactive bladder took 10 grams of pumpkin seed oil per day for 12 weeks, and their symptoms improved on a questionnaire. In another study, 117 people who were assigned female at birth (AFAB) took a combination of pumpkin seed oil, sumac bark, and hops extract for 12 weeks. The number of times they needed to pee decreased, both during the day and at night, and their quality of life significantly improved.

Support Healthy Sleep

Pumpkin seeds are a source of tryptophan, an amino acid, with about 576mg of tryptophan per 100g of seeds. Tryptophan helps your body produce melatonin and serotonin, hormones that promote a good night's rest. Melatonin controls your sleep-wake cycle, and serotonin helps regulate mood and sleep. Snacking on pumpkin seeds before bed may help you get a better night’s rest. The zinc, copper, and selenium in pumpkin seeds can also affect sleep duration and quality. Finally, studies show that magnesium can help reduce stress and anxiety, contributors to insomnia.  

Nutrition of Pumpkin Seeds

One ounce of unsalted pumpkin seeds without their shells provides:-

Calories 163

Fat 13.9g

Saturated fat 2.42g

Unsaturated fat 10.09g

Sodium 5.1mg

Carbohydrates 4.17g

Fibre 1.84g

Added sugars 0g

Protein 8.45g

This one-ounce serving contains 2.17mg of zinc. This nutrient helps your immune system work properly. Zinc plays a role in cell growth, pregnancy development, wound healing, the breakdown of carbs, and the action of insulin. Your body also needs zinc for the senses of smell and taste. You'll also get about 2.29mg of iron, a mineral.2 Zinc is part of haemoglobin, which carries oxygen throughout your body, and helps muscles store and use oxygen. Pumpkin seeds are rich in protein, fibre, vitamins, minerals and polyunsaturated fats. Polyunsaturated fats are the "good" fats that the American Heart Association recommends as a replacement for foods with saturated and trans fats. Polyunsaturated fats can help lower your bad cholesterol levels, which may help prevent heart disease and strokes. Polyunsaturated fats can also provide essential fats that your body needs but can't make, such as omega-6 and omega-3 fats. One serving of pumpkin seeds has about 2.5 grams of omega-6 and 22 milligrams of omega-3 fat. In addition, the protein in pumpkin seeds is a high-quality protein, like soy protein, that has all your essential amino acids. Pumpkin seeds are also an excellent or good source of the following minerals:-

Phosphorous

Potassium

Magnesium

Calcium

Iron

Zinc

Sodium

Manganese

Copper

Nutrients per serving 

One thing to be aware of is that pepitas don't have as much fibre as pumpkin seeds, since the hulls have been removed. Most of the fibre is in the hulls. Hulled seeds have about 1.8 grams of fibre per serving. Pumpkin seeds also contain antioxidants, including flavonoids and phenols. These antioxidants help fend off cell damage, which may protect against aging and disease. Research has linked flavonoids to several health-promoting effects, including protection against artery hardening, cancer, and cognitive decline. Phenols also have anticancer, anti-inflammatory, and antimicrobial effects. Roasting pumpkin seeds might increase these effects. Research has shown that roasted pumpkin seeds have an increased number of flavonoids and phenols. Roasted pumpkin seeds are available for purchase, or you can roast them yourself after carving a pumpkin.

Pumpkin Seeds Side Effects

Pumpkin seeds are generally safe to eat, but you'll want to be mindful of their calorie and fibre content. A one-ounce serving of pumpkin seeds has about 163 calories, which makes for a good snack. Allergy to pumpkin seeds is very rare. It's only been reported a few times in people from 3 to 70 years old. The reported reactions range from mild to severe. Most have been mild with local symptoms in the mouth or throat. But a few people have reported vomiting, swelling in the face and throat, itching, flushing, wheezing, faintness and shock. Food allergies usually happen after you've eaten the food a couple of times. Pay attention to how you feel the first few times after you eat a new food. Eating too many pumpkin seeds can still boost your calorie intake, resulting in weight gain. Due to their fibre content, excessive pumpkin seed consumption might also cause bloating, discomfort and gas. Pumpkin seeds are high in vitamin K, omega-3 fatty acids, magnesium, and they also have diuretic effects. Diuretics help move extra fluid and salt out of your body by making you pee more. Because of this, if you're taking blood thinners (such as heparin), blood pressure medicine, or diuretics, ask your doctor before you add pumpkin seeds to your diet.

How to Eat Pumpkin Seeds

You can enjoy pumpkin seeds shelled or unshelled. There are plenty of other ways to eat pumpkin seeds and reap their benefits, including:-

Add them to salads or as a garnish for cooked vegetables, hummus, slaw, soups, and stir-fries

Incorporate pumpkin seed butter into baked goods, energy balls, pesto, sauces, and smoothies

Roast shelled pumpkin seeds

Sprinkle pumpkin seeds onto avocado toast, fruit salad, oatmeal or overnight oats, and yogurt

Whip pumpkin seed protein into blended soups, mashed cauliflower, and smoothies to boost your protein intake

Use them to garnish any meal, like chicken or pasta dishes

Blend them with other ingredients in a dip like hummus, pesto, or guacamole

Bake them into cookies and breads

Pumpkin seeds are tasty and easy to overeat. Because they're high in calories, limit your portions to the recommended serving size of 1 oz, which is a little less than a quarter-cup. One easy way to make your own pumpkin seeds is to scoop the seeds from inside a whole pumpkin. Rinse or soak the seeds to get rid of the stringy orange flesh which surrounds them. You can eat the stringy flesh, too, if you want. But if you don't care for the texture, soaking the seeds for a couple of hours can make your job easier. You can eat them raw, or, toss with about a tablespoon of olive oil, spread them out on a cookie sheet, and bake in a 300 F oven for 30-40 minutes. Roasting the seeds makes them easier to digest, increases their antioxidant levels, and makes them even more delicious. Shelled pumpkin seeds are white and unshelled ones appear green. You can eat pumpkin seeds with or without their shells. Just make sure you drink plenty of water if you eat shelled pumpkin seeds. Water helps your digestive system process the fibre content. Although rare, there have been some reports of men with intestinal blockages after consuming large quantities of shelled pumpkin seeds. You can also find pumpkin seeds with or without their hulls at grocery and health food stores. If you're buying them from the store, check the ingredients because they may have added salt and sugar. You can also substitute pumpkin seeds in any recipe where you might use sunflower seeds or pine nuts.

Healthiest way to eat pumpkin seeds

The healthiest way to eat pumpkin seeds is to roast them yourself from a whole pumpkin. Pumpkin seeds that are straight from the pumpkin are lower in sodium and have more minerals than the ones you buy at the grocery store. So, your second best option is to buy unsalted, raw seeds in their hulls from the grocery or health food store. Pumpkin seeds do have a lot of a chemical called phytic acid, which can bind to mineral nutrients in your digestive system and keep you from absorbing them as well. You can reduce the phytic acid content by soaking or sprouting your seeds before you eat or roast them. 

To soak your seeds:-

Pick through to remove any debris and rinse them until the water runs clear.

Put them in a bowl or jar and add about 2-3 times as much cool water. For instance, for 2/3 cup of seeds, add 1 1/3 to 2 cups of water. Stir so that all the seeds come into contact with the water. 

Soak the seeds at room temperature for 1-4 hours. 

Eat them right away or store them in the refrigerator. 

To sprout your seeds:-

Soak them first as described above.

After they have soaked, drain and rinse them and then add the same amount of fresh water. 

Soak for 8-12 hours in an area with good air circulation. A corner of your kitchen counter is fine. Your goal is to get the seeds to start germinating but not to fully germinate.

You may need to drain, rinse and soak them again for another 8-12 hours until the hull bulges. 

Drain and rinse, and then use them right away or store them in the refrigerator.

Use soaked or sprouted seeds just as you would any pumpkin seeds. Roast or toast them in the oven and then eat them out of hand or add them to your favourite recipes.
