Pumpkin and sunflower seeds deliver almost the same calories in a small handful, but their nutrient strengths are quite different. To keep preparation from distorting the result, both references below are roasted and unsalted.
| Per 30 g | Pumpkin | Sunflower |
|---|---|---|
| Calories | ~172 | ~175 |
| Protein | ~9.0 g | ~5.8 g |
| Fat | ~14.7 g | ~14.9 g |
| Fiber | ~2.0 g | ~3.3 g |
| Magnesium | ~165 mg | ~39 mg |
| Zinc | ~2.3 mg | ~1.6 mg |
Calories and total fat are essentially tied. Protein and micronutrients create the meaningful differences.
Pumpkin seeds: protein and magnesium
The USDA roasted unsalted reference provides about 29.8 g protein and 550 mg magnesium per 100 g. Sunflower seeds provide 19.3 g protein and 129 mg magnesium.
At 30 g, that is roughly 9.0 versus 5.8 g protein and 165 versus 39 mg magnesium.
Sunflower seeds: fiber and vitamin E
Sunflower seeds provide about 11.1 g fiber/100 g versus 6.5 g in the roasted pumpkin reference. They are also particularly rich in alpha-tocopherol: about 26.1 mg vitamin E/100 g, or roughly 7.8 mg per 30 g.
Salt can matter more than the seed
Salted versions can contain hundreds of milligrams more sodium per 100 g than unsalted versions. Compare like with like if sodium matters.
Which is better?
Pumpkin seeds have a clear advantage for protein, magnesium and zinc. Sunflower seeds stand out for vitamin E and provide more fiber.
Because their calorie totals are so similar, mixing them is an easy way to combine strengths.
Serving size keeps the comparison realistic
Both seeds are energy-dense because much of their weight is fat. A small handful, roughly 25 to 30 grams, is a more realistic comparison than 100 grams. At that portion, pumpkin seeds can make a meaningful contribution to protein, magnesium, zinc, and iron, while sunflower seeds stand out for vitamin E and still provide useful unsaturated fat.
The rest of the meal decides which difference matters. Adding seeds to yogurt or oatmeal may be about minerals and texture; using them on a salad may be about crunch and replacing a salty topping.
Roasting changes flavor more than the basic identity
Dry roasting intensifies aroma and can make seeds easier to snack on, but heavily salted or oil-coated products can change sodium and energy intake much more than the difference between pumpkin and sunflower kernels. Check the ingredient list if you are comparing flavored varieties.
Raw and roasted seeds both contain unsaturated fats. Because those fats can oxidize, store opened packages tightly closed, away from heat and light. A stale, paint-like, or bitter flavor is a reason to replace the package.
Seed butters are another way to use them
Pumpkin-seed and sunflower-seed butters concentrate the same ingredients into a spread, but recipes may add salt, sugar, or extra oil. Compare labels rather than assuming the butter has exactly the same profile as plain kernels. Sunflower-seed butter can also be useful in settings where peanut or tree-nut products are avoided, provided the specific product is appropriate for the person’s allergy needs.
If you want to use seeds every day, variety is easy. Pumpkin seeds work well where a savory, substantial crunch is useful, while sunflower seeds blend into breads, granola, salads, and seed butters. Mixing a small amount of each gives a broader micronutrient profile without doubling the portion.
Whole kernels are also easy to overeat straight from a bag because they are compact and energy-dense. Pre-portioning a small handful or sprinkling them onto another food makes the serving more visible. This is especially useful with salted versions, where both calories and sodium accumulate quickly.
Mineral numbers also depend on whether the database entry refers to kernels, seeds with shells, raw seeds, or roasted seeds. Pumpkin “pepitas” are usually the edible kernels, while sunflower nutrition is also commonly listed for kernels without the hull. Comparing the edible portion avoids an artificial difference caused by inedible shell weight. The package label is the best reference when your product has been roasted, salted, or coated.
Both seeds can fit into the same diet without competition. The nutritional difference is useful for emphasis—magnesium and protein from pumpkin seeds, vitamin E from sunflower seeds—not for declaring one unnecessary.
