Growing up as a kid you probably heard the phrase "eat your spinach or no dessert for you!" a lot. Its that leafy green that children around the world detest, and its what gives Pop Eye his strength to save Olive in drastic scenarios, but regardless of whether you like it or not - man is it good for the body.
Iron is a huge source of iron, however its important to note that unless the this form of iron is accompanied by the presence of vitamin C, it is virtually useless to absorb. Using a homemade citrus salad dressing combo of lemons, limes, and oranges, and then drizzling the dressing over spinach can usually help with this issue.
Spinach is also a great source of calcium, but what's even more impressive is its nice inventory of vitamins. Vitamins K, C, E, and A are just a few to be found, and eating spinach on a daily basis will make your bones quite happy.
The beauty of spinach though is the fact that you can "smuggle" it into any dish. You can use it on sandwiches, in pastas, quasadillas, salsas, and so much more, and even if you do like the taste of spinach, since you can use it in such a variety - easy to meet the daily recommendation.
