These seeds taste fantastic if you roast them and add a little bit of salt. They can be a delicious treat and a nutrient-packed snack. If you eat only half a cup of roasted pumpkin seeds a day, you will get a whopping 382 mg of magnesium, which is near the recommended intake for males and more than the recommended daily intake for females. They also contain plenty of zinc and a lot of antioxidants. As a piece of advice, when you roast pumpkin seeds do not exceed 20 minutes because this would cause a series of molecular changes in the nutrient molecules.
