Having a full stomach may help keep you and your spouse from arguing.
A new study shows that being hungry can make you more angry with your spouse.
According to reports, in a new study from Ohio State University, one hundred married couples measured their blood sugar for three weeks.
Participants were all given a voo doo doll that represented their spouse.
Depending on how angry they were with their spouse, every night they stuck up to 51 pins in the doll.
They found people with lower blood sugar levels, which is an indicator of hunger, stuck more pins in their dolls and were more likely to lash out at their spouse.
Experts say too little glucose leaves the brain without the energy it needs to suppress anger and aggressive impulses.
