A doctor says high uric acid is one of the most misunderstood markers in medicine and it could be silently damaging your heart and joints right now

by Adrienne Erin

What if I told you that a common marker in your blood work, one that is frequently misunderstood even by practitioners, holds a powerful key to your metabolic health? What if this same marker could be silently driving inflammation, joint pain, and even heart disease, all while you think you’re following a healthy diet? We’re talking about uric acid, and it’s time for a deep dive into what it really is, where it comes from, and why your high-protein diet might be causing a serious problem.

Most people associate high uric acid with indulging in too much red wine and organ meats, leading to the painful condition known as gout. While there’s a sliver of truth to that, it’s a massive oversimplification. The real story is far more complex and has profound implications for anyone on a low-carb, ketogenic, or carnivore diet. The primary source of problematic uric acid isn’t what you’re eating—it’s what your body is producing internally. Understanding this process is critical to optimizing your health and avoiding the serious pitfalls of elevated uric acid. (Based on the insights of Dr. Robert Cywes)

Key Takeaways

  • High uric acid is primarily caused by your body’s own production (endogenous), not just from eating purine-rich foods.
  • In the standard American diet, fructose is a leading cause of elevated uric acid.
  • On low-carb diets, relying too heavily on lean protein for energy can dramatically increase uric acid production.</
