Spinach is well known for its nutritional qualities and has always been regarded as a plant with remarkable abilities to restore energy, increase vitality and improve the quality of the blood. There are sound reasons why spinach would produce such results, primarily the fact that it is rich in iron. Iron plays a central role in the function of red blood cells which help in transporting oxygen around the body, in energy production and DNA synthesis. Spinach is also an excellent source of vitamin K, vitamin A, vitamin C and folate as well as being a good source of manganese, magnesium, iron and vitamin B2. Vitamin K is important for maintaining bone health and it is difficult to find vegetables richer in vitamin K than spinach. Others include kale and broccoli.
