Humans become addicted to sugar because of the release of dopamine

Now, back to that meal.What happens if in place of the healthy, balanced dish,you eat sugar-rich food instead?If you rarely eat sugar or don't eat much at a time,the effect is similar to that of the balanced meal.But if you eat too much,the dopamine response does not level out.In other words, eating lots of sugar will continue to feel rewarding.In this way, sugar behaves a little bit like a drug.It's one reason people seem to be hooked on sugary foods.
