Remember that age-old piece of nutritional advice that salty foods make you thirsty? It’s wrong.
Scientists have long believed that eating more salt results in urinating more, which causes one to drink more to refuel. But no long-term study has ever looked into the matter to verify the seemingly logical assumption. Now an international team of scientists found evidence suggesting the contrary: Those who ate more salt retained more water, were less thirsty, and were hungrier.
