Is Salt Bad? A Prison Study May Hold the Answer

(The Atlantic) – The groups ran through their research options. The best evidence linking salt intake and high-blood pressure comes from short-term feeding studies, where researchers prepare the meals for participants over several weeks. But it is far too expensive to feed participants for the years it takes for heart disease to show up. And frankly, how many volunteers would follow a bland diet for years? So they considered people already on controlled diets. Nursing homes, they ruled out because many of the elderly have medical conditions that already require eating a certain amount of salt. The military they ruled out because the population is so young and fit that it would take too long for heart disease to show up. That left prisons.
