Beacon Transcript – According to new scientific evidence, salty foods stimulate the appetite, making people crave even more salty delights, not a big glass of water as popular opinion dictates. This might explain Pringles’ slogan, “one you pop, you can’t stop” or Lay’s “you can’t have just one.”
Conventional Wisdom Is in Fact an Overly-Propagated Lie
An international team of scientists trying to simulate the hardships of Martian colonists discovered that eating salty food can increase one’s appetite. Popular belief dictates that salty snacks will only make individuals crave a large glass of water. Apart from all the scientific applications of this discovery, this new piece of information explains why nobody is able to eat just one chip.
The idea that salty foods lead to instant thirst was so deeply embedded in the collective mind that nobody ever decided to study the relation between salt intake and drinking habits. That is, until now when a group of international researchers decided to test the effects of salt intake on astronauts.
As expected, even the team of researchers from Vanderbilt University, the Max Delbrück Center, and the German Aerospace Center built their study on the idea that an increased salt intake will make the Mars colonizers thirstier, therefore drinking more water than usual, depleting resources faster.
During the simulations, while researchers expected the participants to run out of water, they observed that the individuals who consumed more salt had a tendency to eat more food. Surprisingly, water intake was lower than anticipated.
There is An Ounce of Truth in the Old Belief
On short term, salty snacks made the mock spacemen crave more water, however, on long term, the results were completely different. Throughout the years, researchers failed to take into account the fact that salt prompts the kidneys to retain more water. Until now, they believed that people eliminated more salt through their urine as chloride ions and charged sodium attached themselves to water molecules, ending up in urine.
However, new evidence shows that on long term, a person which eats saltier food than normal will drink less water, salt traveling to the urine while water returns to the body. These results puzzled the scientists as nobody expected a study about Mars to conclude that salty foods increase a human’s appetite and decrease their water consumption on the long term.
