Health benefits
In addition to linoleic acid (an essential fatty acid), sunflower seeds are also an excellent source of dietary fiber, protein, Vitamin E, and minerals such as magnesium and selenium [5]. Additionally, they are high in cholesterol-lowering phytosterols.

The hulless or semi-hulless seeds of pumpkins can be roasted and eaten as a snack, similar to the sunflower seed. The seeds are often prepared by separation from orange pumpkin flesh, mixture with a generally salty sauce (Worcestershire sauce, for example), even distribution on a baking sheet, and oven-heating at a relatively low temperature for a long period of time. They are a good source of essential fatty acids, potassium, and magnesium. In Latin America, the seeds are often greenish in color and known as pepitas. One of the typical pumpkin products of Austria is pumpkin seed oil.
