Podcast Episode 12 - Salt vs. Sugar: The Real Culprit in the Heart Disease Epidemic

Episode Summary:

For decades, we've been told that salt is the villain behind high blood pressure and heart disease. But what if salt has been wrongfully accused? In this episode, I dive into the fascinating — and frustrating — story of how salt took the blame for what sugar was actually doing to our bodies.

We'll explore:

• How flawed science in the 1970s led to salt’s demonization.

• The shocking cover-up by the Sugar Research Foundation that shifted blame away from sugar.

• Why insulin resistance — not sodium alone — is the real driver of hypertension.

• How modern processed foods combine sodium, sugar, and refined oils to create the perfect storm for heart disease.

• Why traditional diets — often higher in salt than today’s recommendations — didn’t cause the same metabolic issues.

If you’ve been cutting back on salt yet still struggle with bloating, high blood pressure, or fatigue, this episode is for you. The real key to improving your metabolic health has less to do with salt and far more to do with reducing sugar and improving insulin sensitivity.

What You'll Learn:

✅ Why the “low-salt = better health” narrative isn’t the whole story.

✅ The surprising role potassium plays in balancing sodium and lowering blood pressure.

✅ Why insulin resistance — often triggered by excess sugar — causes your body to retain sodium.

✅ How modern ultra-processed foods have contributed to the rise in hypertension and metabolic dysfunction.

✅ Practical steps you can take today to improve your blood pressure and metabolic health — without obsessing over salt intake.

Key Takeaways:

• Cutting sodium alone won’t fix high blood pressure if you’re still eating a high-sugar, processed food diet.
• Increasing potassium-rich foods can dramatically improve sodium balance and heart health.
• Insulin resistance — driven by sugar, not salt — is the key factor that leads to sodium retention and hypertension.
• Whole foods like avocados, leafy greens, and sweet potatoes are powerful tools for improving your sodium-to-potassium ratio.
• Focusing on insulin sensitivity — through balanced meals, fasting, and reducing refined carbs — is far more impactful than simply cutting salt

Resources Mentioned:

• The DASH Diet and why its success is tied more to potassium than sodium reduction.

• The Sugar Research Foundation cover-up and how it misled public health policy.

• Historical insights into how past populations consumed more salt than modern guidelines but had better metabolic health.
