Does Sugar Make Your Heart Sweeter?
Hunger and Anger continued...
It’s common sense that people are quicker to get angry when their blood sugar is low because they’re hungry, says University of Pennsylvania psychologist Robert Kurzban, PhD.
“The fact that humans act differently when they’re hungry is so well-known that Madison Avenue knows this,” Kurzban says, referring to the Snickers commercial with Pesci and Rickles. “When you’re really hungry, all you can do is think about food.”
But in several blog posts and a journal article, Kurzban has questioned the popular theory that self-control is fueled by blood glucose levels. He cites a recent study that found drinking a sugary beverage did not improve performance on a task requiring self-control.
Still, few people would probably challenge Bushman’s advice for married couples: “They should discuss sensitive topics over dinner, or, better yet, after dinner.”
