India is among top five countries in obesity and now the researchers have found yet another reason for it. An average Indian consumes 10.98 grams of salt per day – 119% more than the recommended limit of five grams per day by the World Health Organization (WHO) and according to a new research, salty food when reduces thirst, it increases hunger.
Intake of excess salt also leads to high blood pressure – a leading cause of cardiovascular diseases (CVDs), which accounted for 23% of all deaths in India between 2010 and 2013.
Increases hunger, due to a higher need for energy
A new research, the results of which were published in the journal of Clinical Investigation, finds that salty food diminishes thirst increasing hunger, due to a higher need for energy. The study - first of its kind - showed 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 Max Delbrück Center for Molecular Medicine in Germany.

"Instead, it turns out to be a very important osmolyte - 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, Luft added. The team also carried out a simulated mission to Mars and an international researchers group found exactly the opposite to be true, where "Cosmonauts" who ate more salt retained more water, weren't as thirsty, and needed more energy.
Eating more salt led to a higher salt content in urine
The results confirmed that eating more salt led to a higher salt content in urine and also found 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.
