This Is Your Brain On Sugar

According to some health experts, eating too much sugar can be as bad for you as smoking or drinking a lot of alcohol. This video from TED Ed explains just what sugar does to your brain and body -- and why it's so addictive.

As the video points out, sugar activates our brain's reward system (just like sex, alcohol and nicotine does), causing pleasure-inducing dopamine to be released. The problem is, eating too many sugar-rich foods (and sugar comes in so many different forms) causes the spike in dopamine to remain at a high level -- and you'll continue to crave more sugary foods.

Thankfully, the video concludes that a wedge of cake once in a while won't hurt you. Learn healthier ways to consume sugar and how to avoid the energy crash sugar can cause.
