Beta-Blockers Are Useless, and Sometimes Risky, for Most Cardiac Patients

Description

  • Beta-blockers offer no survival benefit for most heart attack patients with normal heart function, even though they're still widely prescribed
  • Women face higher risks on beta-blockers, including nearly double the risk of death when given higher doses, while men show no measurable harm or benefit
  • Side effects such as fatigue, dizziness, depression, and sexual dysfunction often burden patients without providing meaningful protection
  • The real root of heart disease lies in damaged mitochondria, which are overwhelmed by linoleic acid (LA) from vegetable oils found in most processed foods
  • You can protect your heart by reducing LA, eating the right kinds of carbohydrates, walking daily, getting safe sunlight, and tracking your HOMA-IR score
