Low glucose in blood may cause spouses to fight more

A sweet candy bar may prevent major fights between husbands and wives, at least if a new study that used voodoo dolls is right. That's because low blood sugar can make spouses touchy, researchers propose.

“We need glucose for self-control,” said Ohio State University psychology researcher Brad Bushman, lead author of the report, which was released Monday in the Proceedings of the National Academy of Sciences, reported Fox News.

The researchers studied 107 married couples for three weeks. Each night, they measured their levels of the blood sugar glucose and asked each participant to stick pins in a voodoo doll representing his or her spouse. That indicated levels of aggressive feelings.

The researchers found that the lower the blood sugar levels, the more pins were pushed into the doll.
