The Salt Fix

For 50 years, we've been told that salt is the enemy-a silent killer that raises blood pressure and causes heart attacks. In "The Salt Fix," cardiovascular researcher James Hart challenges the low-salt dogma. Hart argues that for the majority of people, salt restriction is not only unnecessary but dangerous, leading to insulin resistance, increased heart rate, and fatigue. Hart explains the biology: Sodium is an essential electrolyte for nerve transmission and hydration. When we don't eat enough, our body activates stress hormones to retain it. He critiques the flawed science of the 1970s that led to the current guidelines and highlights new studies showing a "U-shaped curve" where too little salt is just as deadly as too much. The book offers a guide to using high-quality salts (like sea salt) to improve athletic performance, sleep, and energy levels. A controversial but science-backed defense of the crystal of life.
