Double the Dopamine: Why It’s So Hard to Control Your Cravings

Indulging in your favourite food is common during the holiday season and while your new year's resolution may have been to eat more healthy, a neurotransmitter called dopamine could be preventing you from doing that.

Dopamine is a pleasure chemical that plays a role in identifying and reinforcing rewarding/pleasurable experiences. Researchers at Max Planck Institute in Germany decided to use a positron-emission tomography (PET) technique to monitor the peaks of dopamine release while people ate palatable (pleasant tasting) and non-palatable (unpleasant tasting) food. This PET technique also helped identify the brain regions associated with the releases.
