I agree with Kyle a bit.
wild fruit vs dom. fruit & wild animals vs dom. animals
are different topics and should be looked at individually.
In my opinion, the more wild the better as far as health.
This is how I look at it. Going from best to worse
Pure Wild Animals > Grass Fed Bison, Elk etc. > Highly Breed Grass Fed Beef, Lamb etc. > Organic & "Naturally" Raised Grain Fed > Grain Fed Intensively Raised
Wild Fruits > Close To Wild Ancestors (seeded fruit, concord, dom. rasp etc.) > Far From Wild Ancestors (seedless bananas, oranges, grapes etc.)
In other words, the closer to wild the better. Also, keep in mind, some do well with temperate zone fruits, some do well with tropical fruits, depends on you genetic ancestry. I can get wild grapes, but can't eat as much as i can wild raspberries. Every fruits is different.
Its funny how nature can balance things.
Wild grapes I can't eat much of and there are plenty and have a long season.
Wild black raspberries I can eat more of, but are not as plentiful as wild grapes and have a shorter season.
