Eating salt could lead to weight loss, a new study reveals.
Results show that a high-salt intake does not necessarily increase thirst, yet the amount of urine produced is consistent with non-high salt days.
This suggests that the body breaks down fat to produce fluids.
The findings contradict previous research that suggests excessive salt consumption leads to weight gain by causing the body to retain water.
Eating salt could lead to weight loss by encouraging our bodies to burn fat, study suggestsMOST OF OUR SALT INTAKE COMES FROM EATING OUT
An astonishing 70 per cent of our salt intake comes from ready meals and eating out, according to researchers from the University of Minnesota.
The study, published in the journal Circulation, tracked 450 people from across the US for four days.
They found the participants consumed an average 3,501 mg of sodium per day - more than 50 per cent more than the recommended maximum.
Salt added to food outside the home was the leading source of sodium, at 71 per cent, and levels naturally occurring in food came in second at 14.2 per cent.
Sodium from salt added during at-home food preparation accounted for 5.6 per cent and that added to food at the table made up only 4.9 per cent.
Researchers from Vanderbilt University analysed Russian astronauts under the simulation of space travel.
The results, published in The Journal of Clinical Investigation, revealed that despite eating more salt on certain days, the astronauts drank less water, which goes against the theory that salty foods make us thirsty.
Yet, despite drinking less water, the crew still urinated similar amounts.
A potential explanation for this is the astronauts were breaking down fat to produce fluids.
Study author Dr Jens Titze said: 'There was only one way to explain this phenomenon.
'The body most likely had generated or produced water when salt intake was high,' The New York Times reported.
Separate findings also revealed that mice eating a high-salt diet burnt more calories and ate 25 per cent more in order to maintain their weight.
NHS guidelines still advise we limit our salt intake to no more than 6g a day - an approximate teaspoons-worth - to reduce our risk of heart disease and stroke.
This comes after researchers from Boston University found that people consuming less than 6g of salt a day have higher blood pressure.
They claim that the advice to eat less salt is too simple and ignores the fact that salt can raise hormone levels in the body that regulate blood pressure.Share or comment on this article:
