I just watched Why Am I Craving Sweets? | Serving Up Science:
When we eat foods that contain lots of fat and sugar, it’s the natural chemical dopamine that gives us a rush of elation and desire for more.
Interesting! I’ll watch more from this series for sure.

This is a funny coincidence, I posted today about dopamine craving 😁😁With ADHD particularly, there is a lack of dopamine and it's usually what leads us to learning new things, eating certain things, etc...Brains are fascinating!
