Chronic inflammation is linked to many serious diseases. Pumpkin seeds contain healthy fatty acids like omega-3s and antioxidants that help reduce inflammation throughout the body.

2. Promote Heart Health

The nutrients in pumpkin seeds are fantastic for your cardiovascular system.

4. Improve Sleep Quality

Struggling to fall asleep? Eating a handful of pumpkin seeds in the evening might help. They are a good source of tryptophan, an amino acid that the body converts into serotonin and melatonin, both of which are crucial for regulating sleep.

5. Aid in Hair Growth

Pumpkin seed oil, in particular, has been studied for its ability to promote hair growth. One double-blind trial found that men who took a pumpkin seed oil supplement saw a significant increase in hair count compared to those who took a placebo.

Historically, pumpkin seeds have been used as a natural remedy for intestinal parasites. Some studies have shown that consuming pumpkin seeds can help reduce the number of certain parasites in the digestive tract.

How to Use Pumpkin Seeds and Oil

To get the most nutritional benefits, raw pumpkin seeds are often preferred. While roasting doesn't destroy the fiber or protein, it can reduce some of the vitamin content.

• Snack on them: A handful of raw or lightly roasted, unsalted pepitas makes a great, healthy snack.

• Add to meals: Sprinkle them on salads, yogurt, oatmeal, or blend them into smoothies.

• Use Pumpkin Seed Oil: Use cold-pressed pumpkin seed oil as a finishing oil for salads, dressings, or drizzled over soups and vegetables.

Note: Soaking pumpkin seeds for a few hours before eating can help reduce their phytic acid content, which improves the absorption of their minerals.

Potential Side Effects

Pumpkin seeds are safe for most people when consumed in moderation. However, if you're eating a lot of them, be mindful of the calorie count. Some people may also experience an allergic reaction, with symptoms like itching or swelling. If you are on a low-sodium diet, be sure to choose unsalted seeds.
