According to Ron Siojo , "The sunflower flourished in Mexico about 4,000 years ago. In the 16th century, the galleon trade brought the plant to Europe where it became very popular as an ornamental flower plant. It was then established as an oilseed crop in Eastern Europe in the 18th century when Russia imported it via Holland. The first commercial production of sunflower oil begin in about 1830-1840.
Sunflower contains an above average protein, phosphorous, and iron concentration. They are also very rich in B-complex vitamins. Salads, cereals, yogurt, and soup taste better with sunflower seeds sprinkled on them. The seeds, which enrich the nutritive value of vegetables, can be used the same way as one would use nuts for desserts. Sunflower seeds are a healthy snack alternative as well."
