The Lutein-free diet is a diet that excludes green vegetables high in lutein such as spinach and kale and some other vegetables and fruits, and replacing them with alternatives such as lettuce, cabbage, blueberries and raspberries that contain less lutein. The diet is not free from lutein and lutein is needed for healthy eyes. The diet is based on the theory of phagocytosis of pigments first described by research nutritionist Sandra Desorgher (DPsy.) The Lutein-free diet is also known as 'Sara's Diet'
