Notable compounds in each

When to choose each

Reach for pumpkin seeds when protein and iron matter most — they carry substantially more of both, along with a notable dose of zinc. Reach for sunflower seeds for more fibre and their higher vitamin E content, one of the richest plant sources of it. Both are excellent, easy additions to a meal that needs a bit more texture and nutrient density.

Common questions

Which seed is better for iron? Pumpkin seeds, by a wide margin — they’re one of the more notable plant sources of iron, useful for anyone on a lower-meat diet, though pairing with vitamin C still helps absorption.

Are shelled or unshelled seeds more nutritious? The seed itself is identical either way — shelling is purely about convenience and portion control, not nutrition.
