It is a diet that consists of only exotic fruits (bananas, mangoes, coconuts, dragon fruit, avocado etc) that as animals we would have intrinsically eaten as a primary diet and would have grown in our natural habitat in african rain-forests. But because fruits were at the time a resource, out of our controllable and not abundant enough to support us in primitive tribes we began to hunt. Copying other predators.
My thoughts are that in essence it is sustainable but I believe it is better to have this diet and also eat seeds etc.
I think the concept of returning to our animistic natural diet is really beautiful... what are your thoughts on this?
