6. Spinach
Popeye may have popularized this vegetable by eating it out of a can to gain instant strength, but there are plenty of other ways to eat spinach and become a superhero. You don’t have to open a can; you can eat fresh leaves as the base for a salad, as a topping for a sandwich, or as an addition to just about any soup. Put simply; spinach is one of the healthiest foods that you can eat. It has tons of vitamin C and vitamin K, as well as fiber and phytochemicals that benefit your eyes. Be like Popeye and eat more spinach!
