good nutrition doesn't have to be complicated. 

in the words of Ray Peat, 

"Animal proteins, and fruits, because they contain the lowest levels of toxins, should form the basis of the diet."

Good nutrition is more about removing known toxins and letting the body work

...than it is about adding in anything magical. 

[noticing a trend yet?]

eating a diet rich in traditional animal foods (especially gelatinous meats), 

fresh and dried fruit, 

and high-quality dairy

is a simple, pleasantly tasty way to help your body run at its best.
