Just my 2 cents - people always forget that societies have empirically developed diets over 1000s of years. If you want to know what works, a good starting point is the traditional diet for your ethnic type and/or region. That means organic food, and probably a lot less meat, cheese, white flour, fried food, and sugar for many people. Most of all people might want to keep an open mind and not get rabidly attached to one particular dietary theory but just pay attention to the effect ivarious diets have on your body.
