Did you ever think there could be a link between blood sugar and relationship conflicts? Yes, there is and researchers of a new study suggest full feeling may prevent big fights between husbands and wives.

Researchers enrolled 107 married couples for a 21-day boot camp to know connection between blood glucose and aggression. Blood glucose levels of all the participants were noted down and they were asked to complete a relationship questionnaire to know the level of satisfaction in their married lives.

Analysis of a survey led researchers to predict that decline in blood sugar levels would correlate with increases aggression between the married couples.

In the research, aggression was defined in two ways: aggressive impulse and aggressive behaviour. The difference led researchers to know aggression in thoughts and action. This paved path for the second experiment in the study and that was to test aggressive impulse.

Every participant was given a voodoo doll and 51 pins. They were asked to place as many pins in the doll every night they want to show their level of anger with their spouse.

To test aggressive behavior, researchers made the spouses wear headphones when they competed against each other in 25-part tasks. After winning every task, the winner decided how loud and for how much time to boast the loser with a noise through headphones.

Both the tests unveiled that the lower levels of blood glucose led to more pins poked in the doll and also the higher intensity of their partners to shout through headphones. "Even though the brain is only two percent of our body weight, it consumes about 20 percent of our calories. It is a very demanding organ when it comes to energy", affirmed study researchers.
