They can improve your mood
Sunflowers have a reputation for making people happy, and it's not just because of their cheerful appearance. Their seeds are loaded with magnesium, a mineral that may help alleviate depression, insomnia, headaches, and other life ruiners. Our ancestors got plenty of magnesium from fish, organ meats, and produce grown in mineral-rich soil, but today we have to make an extra effort to incorporate it into our diets. So if you A) like being happy, and B) think they call it "offal" for a reason, skip the sweetbreads and score some sunflower seeds instead.
They've probably saved the lives of countless baseball players
Back in the day, baseball players would often chew tobacco during games. Once the field of medicine advanced beyond doctors endorsing tobacco products, however, the habit's popularity declined, with many players switching to sunflower seeds around the 1950s. The sunny seeds have been a staple of the sport ever since, but you don't have to be a baseball fan to snack on sunflower seeds. Pretty much the only requirement is teeth.
