For many people, a high-sugar diet has become almost accidental. Three quarters of food in the supermarket has added sugar, says Monica Dus, associate professor of molecular, cellular, and developmental biology at the University of Michigan. In the new study, researchers wanted to further examine whether the dulled sense of taste phenomenon was a physiological effect taking place in rats’ senses consuming the high-sugar diet.
As reported in the journal Current Biology, the responsiveness of the nerve that transmits sweetness information from the tongue to the brain was reduced by almost 50% in rats fed a high-sugar diet….
