Avoid Salt for better Health

As we know that people cannot survive without salt .Before the study, the prevailing hypothesis had been that the charged sodium and chloride ions in salt grabbed onto water molecules and dragged them into the urine. The new results showed something different: salt stayed in the urine, while water moved back into the kidney and body.
According to study we find that salty food diminishes thirst and increases hunger, due to a higher need for energy and stamina.
The results, published in the journal of Clinical Investigation, showed something different: As we know that salt stayed in the urine, while water moved back into the kidney and body.
“It’s not solely a waste product, as has been assumed,” said one of the researcher Friedrich C. Luft from Delbrück Center for Molecular Medicine in Germany.“Instead, it turns out to be a very important cosmolyte – a compound that binds to water and helps transport it. Its function is to keep water in when our bodies get rid of salt. Nature has apparently found a way to conserve water that would otherwise be carried away into the urine by salt,” Lu ft added.
On a high-salt diet were eating more. Higher salt didn’t increase their thirst, but it did make them hungrier. Also the human “cosmonauts” receiving a salty diet complained about being hungry. Then the team carried out a simulated mission to Mars and an international group of scientists found exactly the opposite to be true, where “Cosmonauts” who ate more salt retained more water, weren’t as thirsty, and needed more energy.
They divided participants in two groups of 10 male volunteers sealed into a mock spaceship for two simulated flights to Mars and were examined for 105 days.After that the second group was sent for over 205 days.
Both the groups had levied an identical diets and later they were given three different levels of salt in their food.
The results confirmed that eating more salt led to a higher salt content in urine – no surprise there. Nor was there any surprise in a correlation between amounts of salt and overall quantity of urine.
The findings suggest that the increase was not due to more drinking – in fact, a salty diet caused the participants to drink less. Salt was triggering a mechanism to conserve water in the kidneys.
A connection between salt intake and drinking could affect your calculations in diet — you wouldn’t want an interplanetary traveler to die because he liked an occasional pinch of salt on his food. The real interest in the simulation, however, was that it provided an environment in which every aspect of a person’s nutrition, water consumption, and salt intake could be controlled and measured.

Scientists have known that increasing a person’s salt intake stimulates the production of more urine — it has simply been assumed that the extra fluid comes from drinking. Not so fast! say researchers from the German Aerospace Center (DLR), the Max Delbrück Center for Molecular Medicine (MDC), Vanderbilt University and colleagues around the world. Recently they took advantage of a simulated mission to Mars to put the old adage to the test.
