Being Hangry: The neuroscience behind hunger and a sour mood

Where are our meals? The service at this restaurant is awful. We’ve been waiting for an hour and have yet to even see a glimpse of our appetizers! Those people ordered after us and they just got their food! I’m starving! Don’t tell me to relax; I’m starting to get hungry!


Eek! Sound like an all too familiar scenario? “Hanger”, the portmanteau or mash-up of the words hungry and anger describing a state of rage caused by lack of food, may actually be linked to levels of the neurotransmitter serotonin in the brain.

Be kind, consume some glucose

What happens to our mood when our body is running low on glucose a.k.a. sugar? Researchers at the University of Kentucky were interested in the link between low glucose levels and aggressive behavior, so they designed a devious study to investigate the sugar-mood association.

In the study, 62 college students were asked to drink lemonade containing either sugar or a sugar substitute. After drinking their randomized beverage, the students participated in a “game” where they were told that they were competing against an opponent to see who could press a button the fastest.
