Kale vs Spinach
You really can't go wrong choosing either one of these two superfoods, or any green vegetable for that matter. You can replace spinach with kale in any spinach-y recipe. Even though spinach is famous for being Iron rich, Kale has more!
Both kale and spinach are jam-packed with vitamin C, A and K but in every one of these kale is richer. Although spinach has a little more fiber and magnesium, kale wins in calcium and protein. Which is great if you are lactose-intolerant and can't use dairy as a source for these essential nutrients.
Kale is also denser and higher in calories than spinach so you will need half the serving size to feel fuller. Move over, spinach — there's a new super green in town, and it's kale!
