Sugar and The Brain

By: Rebecca McInroy

Why is it hard to have just one of those delicious slices of pound cake over the holidays? Well, it turns out it has less to do with the creamy butter and more to do with the way our brains react to those sweet white grains of sugar.

In this edition of Two Guys on Your Head, Dr. Art Markman and Dr. Bob Duke discuss the ways our brains respond to sugar by releasing dopamine. While we may think this dopamine is supposed to make us feel good, what the chemicals in our brains are trying to do is to teach us that this sugar is a good thing and that we want more of it for our survival. This might have been beneficial to us 150,000 years ago, but with sweets in every candy dish, gas station, and coffee shop, craving sugar has its consequences.
