An amazing phytonutrient called nasunin is found in the eggplant skin. Nasunin is a potent protector and free radical scavenger that has been shown to protect the fat lipids in brain cell membranes from damage. Cell membranes are almost entirely composed of lipids and are responsible for protecting the cell from free radicals letting nutrients in and waste out, and receiving instructions from messenger molecules that tell the cell which activities it should perform. Because the skin is so valuable to your health it is important to eat eggplant that are organic and synthetic free. Eggplant is also packed full of vitamins and minerals.
