Pumpkin seeds

Pumpkin seeds provide about 559 kcal per 100 g, with 30 g of protein, 11 g of carbs, 49 g of fat and 6 g of fiber. They are very concentrated calories: half of their weight is fat, but they also deliver a rare amount of protein for a plant food, almost comparable to some meats.

Nobody eats 100 g in one go, and that is the whole point. A 25 g handful means about 140 kcal, 7.5 g of protein, 12 g of fat and 1.5 g of fiber. Think in portions rather than per-100 g values, and weigh them at least the first few times to calibrate your eye.

Pumpkin seeds are one of the most concentrated food sources of magnesium: a few tens of grams cover a significant share of reference intakes. They also supply zinc, iron, phosphorus, manganese and copper, minerals involved in energy metabolism, muscle contraction and the normal functioning of the immune system.

They also contain vitamin E, phytosterols and mostly unsaturated fatty acids. Beware of phytates, though, which are present in seeds: they partly limit the absorption of iron and zinc. This is not an issue in a varied diet, but do not rely on them as your only source of these minerals.

When appetite is the limiting factor, pumpkin seeds are a handy ally: 40 g added to a bowl of oats or plain Greek yogurt adds about 220 kcal and 12 g of protein without extra volume. They slip into a snack mix, a homemade muesli or a bag to carry to the gym.

Their protein is limited in lysine: pair them with legumes, dairy, eggs or whey to cover your essential amino acids. They complement your main proteins rather than replace them, especially if you aim for a high daily protein intake.

In a deficit, pumpkin seeds are not forbidden, but their calorie density demands rigor. A 15 g portion is about 84 kcal: enough to add crunch to a salad or a skyr without blowing your budget. The trap is the bag nibbled in front of a screen, where 100 g disappear in minutes.

Thanks to their protein, fat and fiber, they are quite filling for a small volume. Many people find that a small weighed portion at the afternoon snack helps them last until dinner. If you track with a scale, they remain compatible with almost any cutting plan.

Pick plain shelled green seeds (pepitas) with no added salt, sugar or coating. Check the date: their unsaturated fats go rancid over time. A sharp smell or bitter taste means the seeds should be thrown away. Whole seeds, with their white hull, are richer in fiber but less pleasant to chew in large amounts.

Store them in an airtight jar, in a cool dark place, or in the fridge in summer. To toast them, use a dry pan over medium heat for 3 to 5 minutes, stirring, or an oven at about 160 °C. Watch them closely: they burn fast and turn bitter, so take them off as soon as they puff up and turn lightly golden.

Sprinkle them on oats, Greek yogurt, skyr or fromage blanc for a heartier breakfast. Add them to a spinach and avocado salad, a quinoa bowl or roasted vegetables for texture. Blended, they make an original pesto with olive oil, garlic and lemon.

You can also fold them into homemade bars, protein cookies or homemade granola, keeping in mind that each tablespoon added weighs about 8 g and 45 kcal. A small amount of seeds spread across several meals is often easier to manage than one large portion.

The first mistake is treating them as a light food because they are natural. The second is buying salted or caramelized versions, which add sodium or sugar. The third is eating large amounts at once: their fiber and fat can cause digestive discomfort or bloating in some people.

This information is general and does not replace the advice of a healthcare professional. If you have a seed allergy, a digestive condition or a specific medical diet, ask for advice before making them a regular part of your eating. If you doubt your mineral intake, a blood test is more reliable than how you feel.
