4. Eat Something
Registered dietitian Jan Patenaude from Carbondale, CO, realized that low blood sugar can trigger a fight. “One time an ex hadn’t eaten anything in about six hours. In the middle of a fight he had instigated, I poured him a glass of orange juice and within minutes, he was apologizing for being a jerk,” she says. Chowing down on any sort of snack or caloric beverage might do the trick, but Patenaude likes fruit and fruit juice because they’re fast-acting and contain natural ingredients and nutrients.
