I use English baby spinach leaves in my recipes. This more modern variety of spinach is more tender than older varieties and has small flat leaves. They can be eaten raw or lightly cooked. Spinach is a powerhouse food, it contains vitamins, minerals, antioxidants and phytonutrients. Spinach is low in carbs but high in insoluble fibre and may improve eye health, and help prevent heart disease and cancer.
