The Yellow/Green group is rich in Lutein which is mainly for eye and brain function. Dark green foods like spinach, avocado and some lettuce are all a good source of Lutein. Like Lycopene and Beta Carotene, Lutein is fat soluble which means it is better absorbed from the blood stream into the eyes via a special protein transporter. It travels to the part of the optic nerve that deals with UV rays, then to the brain where it acts as an antioxidant. 10mg of spinach per day (equal to about 100g of spinach) provides protection to eh Macula which is the part of the eye that absorbs UV rays. When the Macula is damaged to get AMD (Age-related Macula Degeneration) which is a common cause of blindness in people over 65. #poweredbyherbalife #info #learning #yellowgreengroup #phytonutrients #drdaveheber # (at Brighton)
