Wash. U. Researchers Discover Why We Love Fat So Darned Much
So we all know, deep in our hearts and thighs and especially our tongues -- and despite all those resolutions we made a couple of weeks ago -- that fat is one of the most awesome things that can ever happen to a piece of food. But it is the goal of Science to illuminate and explain the mysteries of life and nature, and so a group of scientists at Washington University School of Medicine has taken the first step to discover why we love fat so much.
There's now an honest-to-God scientific explanation as to why these taste so good.
"My key interest in fat is to know why we crave fat," says M. Yanina Pepino, one of the scientists who worked on the study, which appears in the current issue of the Journal of Lipid Research. The answer, or at least part of the answer, lies in a gene called CD36, which is connected to the taste buds. People who make more of the CD36 protein have an easier time detecting the presence of fat in food.
This does not mean, Pepino stresses, that they like fat more. "We have to learn what the signal means," she says. "It could be how much fat they need to absorb to get the signal of satiety. This is just the tip of the iceberg, the beginning of the story."
