The researchers found that rats who over-consumed fructose had damaged synaptic activity in the brain, meaning that communication among brain cells was impaired.

Heavy sugar intake caused the rats to develop a resistance to insulin — a hormone that controls blood sugar levels and also regulates the function of brain cells.
