Coming straight to the point, here are the reasons why popeye preferred eating a spinach tin and nothing something else.
Spinach is rich in Iron
Spinach is well known for its nutritional benefits and has always been regarded as a vegetable with an outstanding ability to restore energy. There is a reason to this effect, mainly for the fact that it is rich in iron. Iron plays a central role in the function of red blood cells which help in transporting oxygen around the body, in energy production and DNA synthesis.
