What Happens to Your Body When You Eat Pumpkin Seeds

If you’re looking for a simple way to give your meals a nutritional boost, pumpkin seeds are a tiny—but mighty—ingredient worth adding to your plate. Whether sprinkled over oatmeal, blended into smoothies or tossed onto salads, these versatile seeds deliver an impressive mix of nutrients with every bite. Packed with heart-healthy fats, plant-based protein, fiber and essential minerals, pumpkin seeds offer a wide range of science-backed health benefits—from better sleep to balanced blood sugar.

We asked dietitians to break down what makes pumpkin seeds so beneficial—and how to incorporate them into your daily routine.

Why We Love Pumpkin Seeds

May Support Heart Health

Pumpkin seeds are a great source of omega-3 fatty acids, which are known for increasing HDL cholesterol. HDL cholesterol is often referred to as the “good” cholesterol because it removes cholesterol from the blood and carries it to your liver, helping reduce the risk of heart-related health issues.

Help Maintain Healthy Blood Sugar Levels

Pumpkin seeds are packed with protein and some fiber, which can help prevent high blood sugar spikes. This makes them a smart snack option for those managing diabetes or anyone aiming to avoid energy crashes.

May Promotes Better Sleep

Pumpkin seeds are a good source of magnesium—a mineral that supports muscle relaxation and has been linked to improved sleep quality. They also contain tryptophan, an amino acid that helps produce serotonin and melatonin, which support restful sleep. “[They make] make for a great bedtime snack,” adds Maggie Michalczyk, RDN.

Provide Plant-Based Protein

If you’re looking to add more plant-based sources of protein to your diet, consider pumpkin seeds. Just 30 grams (about 1/4 cup) of pumpkin seeds provides 9 grams of protein. Research shows that eating more plant-based protein sources may help reduce the risk of chronic diseases such as diabetes, metabolic syndrome, and certain types of cancer, and also support weight management.

May Support Hormonal Health

“Pumpkin seeds are great for women because they’re a good source of zinc, which helps to support hormone health by helping to regulate progesterone,” says Michalczyk. This helps with female reproduction. “They also contain phytoestrogens, which can help regulate estrogen activity.”

Are Pumpkin Seeds Safe for Everyone?

Generally, pumpkin seeds are well tolerated by most people and easy to incorporate into a balanced diet. However, “If you have a seed allergy or struggle with certain digestive issues—like diverticulitis—you might want to check with your doctor before diving in,” says Lauren Manaker, M.S., RDN, LD, CLEC. 

“People with digestive issues who should follow a low fiber diet should avoid pumpkin seeds or eat them in moderation,” to prevent further issues, says Michalczyk.

“Also, if you’re buying pre-packaged seeds, watch out for added salt or flavorings that can sneak in extra sodium or unwanted ingredients,” adds Manaker.

5 Ways to Enjoy Pumpkin Seeds

While roasted pumpkin seeds certainly make for the ideal salty, satiating snack, there are other ways to enjoy them. Here are some of Manaker and Michalczyk’s favorite ways to enjoy pumpkin seeds in their day-to-day lives.

• Sprinkle on breakfast bowls: Top overnight oats, yogurt or smoothie bowls with a spoonful of pumpkin seeds for a crunchy, nutritious addition.
• Bake into snacks: If you love baking, mix into your homemade granola bars, muffins or breads.
• Toss into salads and grain bowls: Pumpkin seeds add a great crunch to your salads or bowls.
• Blended into smoothies: For a protein boost, blend shelled pumpkin seeds (pepitas) into your smoothie, or try a pumpkin seed protein powder. Can’t find one at your local store? You can make it at home yourself!
• Roast with your favorite seasoning: Make your own snackable batch with spices or condiments like Everything Bagel Seasoning for added flavor.
