In 1942, a 33-year-old woman walked into a hospital with a crisis. Her blood pressure was so dangerously high that it was destroying her eyes, and her kidneys were beginning to fail. At the time, there were no effective treatments. In a last-ditch effort, her doctor, a German refugee named Walter Kempner, put her on a radical experimental diet: nothing but rice, fruit, and juice, with almost zero salt. He told her to come back in two weeks.
But due to his thick German accent, she misunderstood and returned two months later. When she finally came back, she wasn’t malnourished or worse; she was transformed. Her blood pressure had plummeted from a life-threatening 190/120 to a healthy 124/84. The damage to her eyes had resolved, and her previously swollen heart had shrunk back to a normal size. By complete accident, Dr. Kempner had stumbled upon something extraordinary.
Fast forward over 80 years, and we are still fiercely debating salt. You’ve likely seen viral videos and articles telling you not to worry about your salt intake, while at the same time, major health organizations like the American Heart Association urge you to cut back drastically. It’s a confusing mess of conflicting advice. Who should you believe? Thankfully, a brand-new, massive review of all the research to date has just been released, and it finally gives us the clarity we’ve all been waiting for. This article will break down the entire salt saga for you, from its controversial history to the definitive new evidence, and give you a practical plan for your own health.
