Milk and cookies, peanut butter and jelly, chips and soda. Ever wonder how that last one came to be? Sure it's common to believe that salty snacks leave you thirsty, but new research says it's not really thirst you're trying to quench, but more hunger.
In a recent simulated trip to Mars, scientists tested whether salty snacks led to drinking more water, thus producing more urine.
One group was tested for 105 days, the other for 205. They had identical diets with the exception of salt intake.
Surprisingly, the group with a salty diet drank less than the other group. Researchers said that salt triggers a mechanism in the kidneys to hold onto water and produce urea, which eats up energy and causes hunger, not thirst.
It was previously believed that salt grabbed onto water molecules in the body and dragged them out via urine, but that's not the case.
