Turns out, there’s a scientific reason you’re elbow-deep in salty snacks every time the pressure hits When your stress levels skyrocket, your urge to snack spikes, too. So why do we want something salty instead of something sweet or savory?
There might be a physiological reason why you reach for the a packet of Lays instead of that candy bar when your stress levels are rising. In fact, animal research from the University of Florida suggests that consuming salt can actually decrease the amount of stress hormones like cortisol that are released during psychological stress. And it’s likely that a similar effect takes place in humans, too, says one of the lead researchers Eric Krause, Ph.D.
You don’t need a lot of the salty stuff for this to happen, either: Raising your body’s sodium levels by just 1 to 2 percent is enough to suppress the production of your stress hormones, he says. A personal-sized bag of potato chips might be enough to get you to that level, Krause explains. What’s more, Krause and other researchers have found that the body’s oxytocin levels”a feel-good hormone associated with pleasure and comfort”increase when salt levels increase, too.
Go ahead and grab a small salty snack next time you’re stressed, but watch your portions: Many salty options, like chips and fries, tend to be high in fat and calories. If you want to watch your waistline, reach for nuts to satisfy the need for salt and crunch. They’re full of healthy fats, which have been shown to lower cholesterol and reduce the risk for heart disease. Just keep your total sodium intake to less than 2,300 milligrams (mg) a day. And if you have high blood pressure, you’ll want to keep it lower”you shouldn’t exceed 1,500 mg then.
