Hunter-gatherers serve as wonderful models for examining the food habits of humans. Not only has hunting and gathering been practiced since long before anatomically modern humans appeared, but the people that practiced this method of food acquisition represented some of the healthiest people on the planet (those that were still consuming their traditional diet and had ample space to practice their diet and lifestyle).
Most everyone recognizes that there is truth to saying “you get what you pay for”. For the most part, cheaper products don’t function as well as higher priced goods. Further, products made with cheaper materials don’t last as long and are more likely to be defective and/or break sooner than the higher priced items.
If people were to examine the lives of wild animals, they would clearly see that these organisms are responsible for every aspect of their lives—acquiring nutrition, keeping warm, avoiding predators, rearing young, and so on. If we contrast this with farm animals, we see a completely different existence.
