Sunflower seeds

"The possibility that the most cheerful plant in the world can produce such delicious and nutritious seeds seems absolutely fitting and expected. The whole face of the sunflower is a Fibonacci spiral of seeds, the most efficient way of packing seeds into the space provided. Isn’t nature clever? Sunflower seeds have some poly and monounsaturated fats and protein, which makes them a good, light snack for those trying to lose some weight as they have very low calorific value. Sunflower seeds are fun to eat too, as well as delicious!"
