Spinach is a rich source of major micronutrients such as iron, manganese, zinc, and magnesium and also contains small quantities of vitamin E, A, C, K, folate, thiamine (B1), pyridoxine (B6), riboflavin (B2), and a rich source of fiber. Adding dried spinach flakes to soups, sandwiches, salads, spreads, casseroles, and pasta sauces is simple and tasty. For all of the bakers out there, try incorporating spinach in breads, muffins, or even cakes to create a healthier treat that tastes great.
