Sunflower seeds are one of the most commonly available seeds. The sunflower plant belongs to the daisy family, and probably originated in North America: North American Indians cultivated the flowers as long as 2,000 years ago. A good source of potassium and phosphorus, sunflower seeds also contain protein, iron and calcium.
Sunflower seeds can be eaten whole, raw or cooked. They're added to the top of bread loaves and cakes, or sprinkled into salads or over breakfast cereals.
