Sweet tastes activate neural pathways that increase cravings for sugar and food.

“So the way that your brain is designed is when there's an increase in dopamine, in the mesolimbic reward pathway, there are signals sent to an area of the brain called the striatum, we're going to spend a little bit of time today in the striatum. It's got a dorsal part, meaning in an upper part and a ventral part, which means a lower part. And the dopamine sent to those area, places us, excuse me, into modes of action, to pursue particular things.”

“So when you ingest something sweet, very quickly there are signals sent from those neurons in your mouth to brain areas that cause you to seek out or at least pay attention to, the source and the abundance of those sweet things. They literally change your perception.”
