Have you ever wondered why you get so damn angry when you’re starving? Researchers suggest that we get angry when we’re hungry because of the drop in glucose, which powers the brain. When this happens, it is much more difficult to accomplish simple tasks and to behave within socially accepted norms. Researchers also suggest that your appetite hormones fire up regions that are linked with stress and anxiety, which affects your overall mood and the way you treat others. A study done at Ohio State University shows that couples who are well-fed are less likely to be aggressive toward their partners than those who are glucose-deprived. When glucose levels fall, your brain struggles to control your emotions, so you’re more likely lash out at those who are close to you. The lesson here is, if you’re hungry, then eat, for your and everyone else’s sake.
