It's a fun product. When I meet someone at a party and tell them where I work, they smile. People love hot dogs. --Bob Schwartz, VP of Sales, Vienna Beef in Chicago (Jackson 1999:106; see below, Hot dogs)
Flavor cue. 1. The usually pleasant aroma and taste of cooked animal flesh (i.e., muscles and skin). 2. Intensely flavorful molecules created a.as myoglobin, the red pigment of raw steak, turns brown and a flavor-rich coating forms (as juices evaporate from the meat's surface), and b.as the browning reaction releases furans, pyrones, and other carbon, hydrogen, and oxygen molecules which provide the complex oniony, nutty, fruity, chocolate, and caramel-like tastes we prefer to the bland taste of uncooked meat and raw vegetables (McGee 1990).
Usage I: The aroma of sizzling beefsteak basted with sage and garlic sauce is an irresistible chemical signal transmitted when a chef brushes the meat with seasonings and sears it with flame. According to McGee, "All cooked foods aspire to the [rich and flavorful] condition of fruit" (1990:304).
Usage II: In Nonverbal World, the essence of charbroiled steak evokes an emotional desire to approach the aroma. Among the most evocative of all chemical signals processed by the brain are those emanating from meats and meaty consumer products, such as the Big Macsandwich and fried Spam.
Evolution I. As did late-Devonian amphibians, early mammals of the Cretaceous and early primates of the Paleocene epoch passed through a predominantly flesh-eating stage. Acting in accordance with a primeval chemical code, amphibians pursued fish (and fellow amphibians), while mammals and primates pursued mainly insects. With so many carnivores and insectivores on the family tree, we respond to meats with an extreme alertness, as if scripted to do so by the ancient code.
Evolution II. "Scientists theorize that the shift to hunting and meat eating was a key adaptation that let our ancestors spread beyond Africa and led to the dramatic increase in brain size associated with our human lineage. This 'dietary revolution,' as one paleontologist put it, could have changed the human facial structure by reducing the size of the molars, which previously needed to be large to chew tubers and raw vegetables. As the protruding jaw began to recede, more of the skull could be used to house the brain. And a diet of fat-rich bone marrow could lead to the development of the brain cells" (McCafferty 1999:22).
Kebabs. "A huge kebab made with 1,500 chickens was cooked at this tourist resort [in Limassol, Cyprus] Sunday [June 10, 2001] in a bid to make the Guinness Book of Records" (Anonymous 2001:A3).
Media. According to Scientific American magazine, in 1999 the per capita U.S. consumption of beef was 64.7 pounds (chicken = 49.2, pork = 48.8; Anonymous 2000D).
Prehistory I. Two m.y.a. our first human ancestor, Homo habilis, wandered east Africa's arid savannah grasslands in search of ripe fruit, nuts, tubers, and berries--and small game, bird eggs, insects, and edible grubs. It is likely that Homo's original "hunting instinct" involved thecorticomedial division of the amygdala, which plays a role in mammalian hunting psychology today (Carlson 1986:486).
Prehistory II. On the savannah, meat made up 20-to-30 percent of the early human diet, as it did that of historical hunter-gatherers such as the !Kung San Bushmen of Botswana.
Prehistory III. So appealing is the taste of cooked meat that ". . . after early humans migrated into Australia and the Americas, the heavyweight animals of these new continents were driven to extinction within a few thousand years" (Anonymous 2001F:A1), according to reports inScience (June 2001). Mammoths, camels, mastodons, and the glyptodont, as well as giant sloths, snakes, lizards, birds and marsupials, were hunted, cooked, and eaten to extinction, according to the now more widely accepted "blitzkrieg model" of anthropologists.
RESEARCH REPORT: A craving known as meat hunger is a "widespread phenomenon among peoples living at a subsistence level [i.e., who are not vegetarians by choice]" (Simoons 1994:6). (N.B.: In the U.S., despite well-stocked produce displays, shoppers spend the largest portion of their supermarket dollar on beef, chicken, fish, and pork.)
Neuro-notes. 1. We crave meaty taste because the amphibian brain's hunger for flesh is older than the primate brain's "acquired taste" for fruits and nuts. 2. As it influenced the pursuit, handling, and killing of game, the amygdala also stimulated the release of digestive juices in preparation for eating the kill. Thus, today, hidden aggressiveness in the meat-eater's code makes a sizzling steak more exciting than a bowl of fruit. This explains, in part, why (when possible and affordable) meals throughout the world are planned around a meat dish.
