In fact, yes — new research shows that fatty diets break down neurons in your brain, making you stupid.
In the study, groups of mice were fed high- and low-fat diets. After three months, the mice on the fatty diet were not only obese, but lost synapses.
“What happens in obesity is (brain cells called) microglia stop moving...and start eating synapses," Dr. Alexis M. Stranahan of the Medical College of Georgia told Science News. "When microglia start eating synapses, the mice don't learn as effectively."
The good news is that the damage can be repaired, according to the study published in Brain, Behavior and Immunity.
Once scientists put the mice back on a low-fat diet, brain function returned.
