Your Brain on Sugar

Do you ever wonder why the more sweets you eat, the more you crave them? The good news is you are not alone.

Lucky for us, neuroscientist Nicole Avena broke down the effect of sugar on our brains and bodies in TED-Ed‘s latest animated installment.

According to Avena, when we eat sugar a signal is sent from the tongue to the cerebral cortex that activates a “rewards system.” This in turn encourages us to eat more. A huge part of the rewards system is the release of dopamine in our brain, which, when put into overdrive, can be addictive.

Thankfully, we don’t have to go completely cold turkey and walk away from sugar all together. In moderation, sugar is a healthy part of a nutritious diet, but on in small doses.
