Guests staying at Bruno Comby's hotel and restaurant in the Chateau Montrame outside of Paris, France smell a number of fresh fruits, vegetables, meats, fish, nuts, and insects (all raw) before eating them. Bruno Comby, author of "Delicious Insects" (in French) lives and works in the Orkos Institute in the 17th century Chateau Montrame. His institute serves a raw diet he calls "instinctology" and describes as the Paleolithic nutritional practice by early human hunter-gatherer ancestors. Comby grows insects in cages for food.
