On your next flight, would you enjoy a dinner of roast dinosaur? There are several scientific studies going on that examine the diet of Stone Age humans. The rumor is that cruise lines, airlines and hotel chains are interested in serving foods that include more natural and healthy ingredients.

Actually, just kidding about dinosaur on the menu. If you ever stayed awake in history class, you’d know those beasts were gone from the earth several million years before man arrived. However, the cavemen's simple diet, primarily of meats, is considered healthy for today’s humans by some nutrition experts. Just don’t try convincing a vegan of that.

Stone Age people were hunter-gathers who found food, primarily animals, within short distances of where they lived. They did eat some wild grasses and beans, but researchers claim vitamin-rich liver, kidneys and brains were their favorites. By the way, have those researchers considered that cavemen died at 30 of old age?
