What Sugar Can Do To Your Brain!

How sugar affects the brain

In this 5 minute animated video, Nicole Avena creatively and graphically explains how sugar affects our brains.  It enters our bodies though many eye catching and decadent cakes, candies, ice cream and other treats.


It’s also in ketchup, sauces, sodas and other forms that are less obvious than the sugar treats that entice our sweet teeth!


It takes several different names in the foods we consume.  Dextrose, lactose, maltose, sucrose, starch and glucose are all different forms of sugar that often enter our bodies, sometimes unknowingly!


When we are bombarded by a lot of sugar, insulin is then produced.


Dopamine receptors in our brain are a part of our rewards system.  If we eat too much sugar, the dopamine response doesn’t level out like it would with a normal meal.  We continue to want more sugar, similar to a drug addiction.  So over consumption of sugar can wreak havoc on our bodies.
