We have all heard that low blood sugar can lead to anger, among other things. But how much do we actually focus on the role of food on our moods and relationships? According to findings just published in the Proceedings of the national Academy of Sciences, missing a meal can indeed be very bad for your relationship.
In their study, 107 married couples tested their blood sugar levels before their first morning meal and again before bedtime. Each participant was also given a voodoo doll that represented their partner, and they were told to insert up to 51 pins daily, depending on how angry they felt with their spouse.
You guessed it- those with the lowest nighttime blood sugar levels used the most pins. Women overall used more pins, but the difference was not significant. After 21 days the couples were taken to a lab and told that they were going to compete with one another on how fast they could press a button- in order to test aggressive behavior. The winners would then be able to blast their partner with a loud noise through their headphones. Fortunately, they were actually doing this to the computer- but did not know it. Guess who did the most blasting? Those with the lowest nighttime blood sugar levels blasted their partners more frequently and louder.
The conclusion therefore is that if couples eat before having that difficult or potentially heated discussion, their levels of anger and aggression will be down and easier to manage in general. Makes sense- and I plan to remember this when I work with couples on improving communication- which virtually all couples cite as one of the major issues contributing to their relationship problems.
