Want to improve your relationship? Eat something.

If you’d like to get along better with your spouse, don’t let yourselves get too hungry. 

It turns out that hunger can trigger and escalate arguments and discontent. That’s because when you’re hungry, you’re blood sugar is down and your anger levels go up. 

An Ohio State study put the theory to the test. They followed 107 married couples for 21 days. The couples were asked to record their satisfaction with their partner along with levels of anger and number of arguments. They also had to measure their blood sugar twice a day. At the end of the study, they found a direct correlation between low blood sugar and arguments.
