COLUMBUS, Ohio -

If your spouse is angry or yelling at you, you may want to get them a snack.

It seems "hangry" spouses -- that's hungry and angry -- lash out more.

A new study from Ohio State University followed one hundred married couples and measured their blood sugar levels for three weeks.

Each participant was given a voo doo doll that represented their spouse -- and every night they stuck up to fifty-one pins in the doll -- depending on how angry they were with their spouse.

The study 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. That was true even if the couple had what they considered to be a good relationship.

Experts say too little glucose leaves the brain without the energy it needs to suppress anger and aggressive impulses.
