Does obesity reshape our sense of taste?
Date:11/21/2013

normal, it could lead to new treatments," Medler said. "These cells are out on your tongue and are more accessible than cells in other parts of your body, like your brain."

The new PLOS ONE study compared 25 normal mice to 25 of their littermates who were fed a high-fat diet and became obese.

To measure the animals' response to different tastes, the research team looked at a process called calcium signaling. When cells "recognize" a certain taste, there is a temporary increase in the calcium levels inside the cells, and the scientists measured this change.

The results: Taste cells from the obese mice responded more weakly not only to sweetness but, surprisingly, to bitterness as well. Taste cells from both groups of animals reacted similarly to umami, a flavor associated with savory and meaty foods.
