There is no perfect diet

[Unkown]

I might say that the closet to a perfect diet is your "ancestral" diet basically the food your ancestors adapted to consume which you need to know your heritage and where you ancestors used to live, for example : someone living in Saudi arabia, found out he's mostly arab and his ancestors used to live in the arabian peninsula mostly in the deserts, he found out his race and where did his ancestors belong, which means his diet would be mostly camel, goat meat, and additional "lizard" meat, consuming camel and goat milk also, bread, lots of dates etc.
