Can our genes be making us fat? Science Daily

While high-fat foods are thought to be of universal appeal, there is actually a lot of variation in the extent to which people like and consume fat. A new study in the March issue of the Journal of Food Science, published by the Institute of Food Technologists, reported that two specific genes (TAS2R38-a bitter taste receptor and CD36-a possible fat receptor), may play a role in some people's ability to taste and enjoy dietary fat. By understanding the role of these two genes, food scientists may be able to help people who have trouble controlling how much fat they eat.

Genetic influences on oral fat perception and preference: presented at the symposium "the taste for fat: new discoveries on the role of fat in sensory perception, metabolism, sensory pleasure and beyond" held at the institute of food technologists 2011 annual meeting, new orleans, la., june 12, 2011.
