WASHINGTON (AP) -- A new study suggests that a quick candy bar may stave off major fights between husbands and wives. At least it may keep them from sticking pins into voodoo dolls of each other.
Researchers monitored nightly blood sugar levels of 107 married couples for three weeks, asking them to stick pins into a voodoo doll representing their spouses to measure aggression. They found that the lower the blood sugars, the higher the crankiness, and the more pins were pushed into the doll.
Ohio State University psychology researcher Brad Bushman calls their mood "hangry," a combination of hungry and angry. He says the brain, which is 2 percent of body weight, consumes 20 percent of our calories.
The study was released Monday by the Proceedings of the National Academy of Sciences.
