I'm sure it has nutritional value. As do many of the "super foods" suppliments out there. But personally I like to eat leafy greens, cabage and the like in order to fill my stomach. That way I'm full and dont want to eat crap.
I don't do this for my family, my friends, women, accolades, pride, or ego. I do it for me and no one else, its just part of who I am.
