Like a taunting teenager, a nosy mother-in-law or a meddling neighbor, food messes with our emotions. A bowl of ice cream can make you happy. An entire carton of ice cream can make you sad. Just the smell of a home-cooked meal when you can’t have one can make you lonesome and a bowl of chicken noodle soup can make you feel better.
It’s no stretch, then, to think that food can also influence our behaviors — and it does. According to cutting-edge research, eating a healthy diet affects much more than your weight and health. It’s been linked to decreases in violence, rudeness and antisocial behavior and increases in IQs, test scores and grades among students.
