The Salt Fix: Why the Experts Got It All Wrong--and How Eating More Might Save Your Life

James DiNicolantonio argues that the long-standing medical consensus to restrict sodium intake is based on flawed data and actually triggers internal starvation signals. He details how low-salt diets can increase heart rate, trigger insulin resistance, and cause the body to leach minerals from the bones to maintain blood levels. The text highlights the "salt-sugar connection," explaining that salt cravings are often a biological defense mechanism and that adequate sodium helps the kidneys process sugar more efficiently. DiNicolantonio presents a physiological framework showing how sodium stabilizes the nervous system and supports athletic performance.
