Enjoying a chocolate bar could prevent some major arguments between husbands and wives.

Researchers monitored nightly blood sugar levels of more than a hundred 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.  Whereas, eating chocolate increases blood sugar levels, and improves moods.
