Greens help to build your internal rainforest and to strengthen the blood and respiratory system. They are especially good for city people who rarely see fields of green in open countryside. In Asian medicine, green is related to the liver, emotional stability and creativity.
Nutritionally, greens are very high in calcium, magnesium, iron, potassium, phosphorous, zinc and vitamins A, C, E and K. They are crammed with fiber, folic acid, chlorophyll and many other micronutrients and phytochemicals. Whenever possible, choose organic. But eating non-organic greens is much better than not eating any greens at all!
Some of the benefits of eating dark leafy greens are:
-Strengthened immune system
-Promotion of healthy intestinal flora
-Promotion of subtle, light and flexible energy
-Lifted spirit and elimination of depression
-Improved liver, gall bladder and kidney function
-Cleared congestion, especially in lungs by reducing mucus
