Breakdown of How Sugar Impacts The Brain and Cognitive Function

It is no secret that glucose, a form of sugar, is the main source of energy for every cell in our bodies, including our brain cells. Because the brain is packed with neurons, it uses more energy than any other organ in the body. 

Our brains reward us for consuming sugar. Whether you are eating a delicious meal, sharing a kiss with someone you love, or enjoying a sugary treat, the mesolimbic dopamine system activates, releasing dopamine (a feel-good brain chemical) and reinforcing that behavior.

While our brains depend on sugar to function properly, too much of this fuel can be detrimental to brain health. Below, we break down how sugar impacts the brain, including its effect on cognitive function, mood, and disease risk.
