38. Spinach
There is no doubt that Popeye was on to something with his love of spinach. The leafy green is an incredibly rich source of iron, magnesium, folic acid, vitamin K, vitamin C, lutein, and more. Studies have found that a spinach-rich diet helps control insulin and blood sugar levels and aids in weight loss.
Raw spinach is the perfect base for a delicious, nutrient-packed salad. Cooked spinach, whether as part of a pizza or eaten alone as a side with garlic and olive oil, actually makes more of the nutrients available to the body, much like cooking carrots.
