Spinach is packed full of good stuff. It has iron and vitamins A and C in it. Vitamin A is great for helping your hair to become stronger and to grow faster. You can eat spinach in many ways so it isn’t hard to add to your diet. You can use it as a base for your salad or add it into lasagna or your morning smoothie. My favorite smoothie is one I make with spinach, yogurt and blueberries.
