Pumpkin seeds are consumed raw, roasted, salted, or unsalted. They are commonly used in cuisines across the world, especially in North America, Europe, and parts of Asia.

- Protein: 7g per 28g serving
- Healthy fats: Especially omega-6 fatty acids and monounsaturated fats
- Fiber: 1.7g per serving (more with shells)
- Magnesium: 37% of the Recommended Daily Intake (RDI)
- Zinc: 14% of the RDI

3. Health Benefits of Pumpkin Seeds
1. Supports Heart Health
Pumpkin seeds are high in magnesium, which helps regulate blood pressure and maintain heart function. Their healthy fats also reduce bad cholesterol (LDL) and promote good cholesterol (HDL).
2. Improves Prostate and Bladder Health
Pumpkin seeds have been shown to benefit men’s health, particularly by reducing symptoms of benign prostatic hyperplasia (BPH) — a condition in which the prostate enlarges and causes urinary problems.
3. Rich in Antioxidants
Pumpkin seeds are a potent source of antioxidants like vitamin E, carotenoids, and phenolic compounds, which help fight inflammation and oxidative stress, reducing the risk of chronic diseases.
4. Boosts Immunity
Thanks to high zinc and iron content, pumpkin seeds support the immune system, helping the body resist infections and maintain overall health.
5. Improves Sleep Quality
Pumpkin seeds contain tryptophan, an amino acid that promotes the production of serotonin and melatonin, helping improve sleep and mood.
6. Enhances Bone Health
The rich magnesium content in pumpkin seeds helps maintain bone density and prevent conditions like osteoporosis.
7. Regulates Blood Sugar
Pumpkin seeds help regulate blood sugar levels due to their low glycemic index and high magnesium content, making them beneficial for people with type 2 diabetes.
8. Promotes Healthy Skin and Hair
Pumpkin seeds are a good source of zinc, vitamin E, and omega-3 fatty acids, which contribute to healthy skin, hair growth, and preventing dandruff and dryness.
9. Aids in Weight Management
High in protein and fiber, pumpkin seeds increase satiety, reduce hunger, and aid in weight loss when consumed in moderation.
10. May Help Reduce Risk of Cancer
Some studies suggest that compounds in pumpkin seeds may help inhibit the growth of certain cancer cells, particularly breast, prostate, and colon cancers.
4. Common Uses of Pumpkin Seeds
Pumpkin seeds are versatile and can be used in many ways, including:
Culinary Uses:
- Snacks: Roasted and salted as a crunchy snack.

5. How to Eat Pumpkin Seeds
There are multiple ways to enjoy pumpkin seeds:
Raw:
High in nutrients but may be harder to digest. Soaking them in water for a few hours improves digestibility.
Roasted:
Enhances flavor. Roast at low heat (around 160–170°C or 325°F) for 15-20 minutes with olive oil and seasonings.
Salted or Unsalted:
Choose unsalted for lower sodium intake if you are watching your blood pressure.

Similar to peanut or almond butter, this is a creamy spread ideal for toast or smoothies.
Pumpkin Seed Oil:
Cold-pressed oil can be used in salad dressings or taken as a supplement.
6. Recommended Daily Intake
A typical serving size is 1 ounce (28 grams), which provides:
- 150 calories
- 7g protein
- 13g fat
- 1.7g fiber
- 14% magnesium
- 23% iron
1–2 tablespoons per day is a safe and effective dose for most people.
7. Possible Side Effects and Risks
While pumpkin seeds are generally safe for most people, there are some potential side effects to be aware of:
1. Digestive Issues
Eating large amounts can cause bloating, gas, or constipation due to high fiber content.

Though healthy, they are calorie-dense. Overconsumption can lead to weight gain if not accounted for in total daily calorie intake.
3. Allergic Reactions
Rare, but possible. Symptoms include itching, rash, difficulty breathing, and swelling.
4. Low Blood Pressure
The magnesium in pumpkin seeds can lower blood pressure. For people on antihypertensive medications, this could amplify effects.

May enhance the blood sugar-lowering effect of medications, so monitor closely.

- You have nut or seed allergies
- You’re prone to low blood pressure
- You’re taking diabetes medication
- You have digestive issues like IBS that flare up with seeds
- You’re trying to manage calorie intake strictly (due to high fat content)
Always consult with a healthcare provider before making major dietary changes, especially if you have chronic health conditions.
9. How to Store Pumpkin Seeds
Proper storage is key to maintaining freshness:
- Raw seeds: Keep in an airtight container in a cool, dark place. Refrigerate for longer shelf life.
- Roasted seeds: Store in a sealed container at room temperature for up to a month.
- Pumpkin seed oil: Store in the fridge after opening to prevent oxidation.
Avoid moisture and exposure to light to prevent rancidity.
