While all leafy, green vegetables are good for you, spinach is perhaps the best of them all. It’s free of gluten, which is great for those who suffer from any type of gluten-related condition. It also has minimal sodium. As for nutrients, spinach is loaded with them. Among them are vitamin K, vitamin A, manganese, folate, magnesium, iron, copper, vitamin B2, vitamin B6, vitamin E, potassium and calcium. It’s also a great source of dietary fiber. Eat it raw in a salad, steam it and enjoy as a side dish, or add it to a soup or casserole.
