Perceiving the Flavor of Fat :: Obesity Health Essays

Perceiving the Flavor of Fat When we crave our favorite foods and snacks, those tasty visions in our heads don't usually resemble that of a large, juicy carrot stick or a sumptuous rice cake. We want fat. It's delicious, it's filling, and it just makes everything taste better. It can also make you considerably overweight, not to mention the heart disease and other complications that can result if dietary fat is not consumed in moderation. The appealing taste of fat may very well attribute for the fact that one in three Americans is overweight ("FDA Approves,"1996). Is there anything that can be done about this terrible problem that affects us all? Many researchers say there is. You can either choose to face the facts and simply steer clear of the nasty culprit, or you can fool your taste buds into perceiving the taste of fat without the real stuff ever actually passing your lips. However, before discussing these options, let's talk a little more about fat itself and some of the things it's responsible for. With the large percentage of Americans that are overweight today, it's no surprise that so many physicians are continually recommending diet changes to their patients. However, the majority of these doctors say that the largest barrier keeping Americans from changing their diets is food taste preference (Soltesz, Price, Johnson, & Telljohan, 1994). The patients don't want to switch to a high-fiber low-fat diet because low-fat high-fiber foods don't taste as good as high-fat low-fiber foods. A big bowl of bran flakes just doesn't have the same calming, pleasurable effects as a big bowl of Blue Bell ice cream. Of course, large individual differences must be acknowledged. Some people may actually prefer the taste of bland foods. In fact, one study done on anorexic individuals found that these people actually disliked the taste of foods rich in fat (Simon, Bellisle, Monneuse, Samuel-Lajeunesse, et. al. 1993). Much of what we now know about fat and its effects comes from studies done on mice and rats. For example, Rockwood (1990) found that adult rats and developing rats prefer a diet with a relatively high level of fat. In addition to showing that animals as well as humans prefer the taste of fat, there also appears to be a link between fat consumption and behavior. Hilakivi-Clarke, Cho, and Onsjafe (1996) uncovered some startling evidence suggesting that a high-fat diet may induce aggressive behavior in male mice and rats.
