The possibility of eye color change is really interesting. From what i've heard i think it's due to the fact that more glutathione is being produced. Glutathione inhibits melanin. I have a friend who has been eating a raw paleo diet for four months and she has seen more change in her skin tone than anything else. She had a tan meditteranean skin tone but it's lightened since paleo, which i guess makes sense if melanin is being inhibited. Has anyone seen skin color change as well as eye color change ? I for one would be very very interested in eye color change. . . but not as enthusiastic about skin color change because I like the tanned appearence.
