High-fat diet changes gut microflora, signals to brain

July 17th, 2015

According to a recent study by UGA researchers, eating foods high in fat—good-tasting french fries, for example—changes the populations of bacteria innate to flora in the digestive tract, or gut, and alters signaling to the brain. The result: People no longer recognize that they are full, which can cause overeating, a leading cause of obesity. "When we switch to a high-fat diet, we reorganize our brain circuits," explained study co-author Krzysztof Czaja, an associate professor of neuroanatomy in the University of Georgia College of Veterinary Medicine. "We change our brain circuits by eating unbalanced foods, and we also induce the inflammation in brain regions responsible for feeding behavior. Those reorganized circuits and inflammation may alter satiety signaling."
