老人们普遍认为,吃盐使人口渴。德国马克斯·德尔布吕克分子医学中心和美国范德堡大学的研究人员推翻了这一说法,并指出吃盐多使人饥饿而非口渴。为了研究盐的摄入是否会影响人体对水分的吸收,研究人员招募了10位男性志愿者,在密封的宇宙飞船中,分别模拟为期105天和205天的火星飞行任务。志愿者的食谱完全相同,但在特定的几周内摄入 Older people generally believe that salt is thirsty. Researchers at the Max Breck Molecular Medical Center in Germany and Vanderbilt University in the United States overruled this statement, noting that eating more salt is more hungry than thirsty. To investigate whether salt intake affects the body’s absorption of water, the researchers recruited 10 male volunteers to simulate a Mars mission of 105 days and 205 days in sealed spacecraft, respectively. Volunteers have exactly the same recipe, but consume it for a specific few weeks
