Is Salt Actually Bad For You? What “The Salt Fix” Says

Most Americans have been told for decades that salt is unhealthy and needs to be restricted.  But is this actually supported by science?  The book “The Salt Fix” by Dr. James DiNicolantonio challenges this mainstream belief and exposes how many salt-related health claims are based on weak or misinterpreted evidence.  As a chiropractor serving Garland and the surrounding areas, I, Dr. Ruy Amador, DC, make it a priority to stay up to date with emerging health research and ideas that might help you in your personal health journey.  Also personal and professional experiences increase my knowledge base.  On the personal side I know this question hit me personaly when my 70+ year old mother had to go to the hospital feeling very sick only to find out that she was suffering from Hyponatremia (Low sodium levels in the blood usually casued by excess water in the body diluting the sodium).  So, if you have questions about salt let’s explore what this important book “The Salt Fix” reveals about salt, health, and pain relief.

Who Is Dr. James DiNicolantonio, Author of “The Salt Fix”?

• Dr. James DiNicolantonio is a cardiovascular research scientist and doctor of pharmacy (PharmD), recognized for his extensive research on salt, nutrition, and cardiovascular health.
• He has authored and co-authored more than 200 peer-reviewed scientific publications, many of which are referenced in “The Salt Fix.” He’s also contributed to journals like the British Medical Journal and Annals of Nutrition & Metabolism.
• “The Salt Fix” references independent studies, historical data, and modern clinical trials to support its arguments—making it a well-researched, evidence-backed book on nutritional science.

How Did Salt Become a Health Villain?

According to “The Salt Fix,” salt started getting a bad reputation in the 1970s based on studies with questionable methodologies.

• Dr. DiNicolantonio argues that early research linking salt to high blood pressure was poorly controlled and did not account for other dietary factors, like sugar intake.
• One quote from “The Salt Fix”: “Low-salt guidelines were adopted long before they were validated by comprehensive science.”
• Despite limited proof, low-sodium recommendations were broadcast by the medical establishment, quickly spreading through Western medicine and the public health system.

What Does “The Salt Fix” Say About Good vs. Bad Salt?

• Quality salt: Natural, unrefined sea salts (such as Himalayan or Celtic sea salt) provide trace minerals and are less processed.
• Poor quality salt: Highly refined table salt is stripped of minerals and often contains anti-caking agents—something “The Salt Fix” encourages readers to avoid where possible.

Is Sugar Worse Than Salt for High Blood Pressure?

One of the most powerful arguments in “The Salt Fix” is that sugar—not salt—is a primary driver of hypertension in modern diets.

• Dr. DiNicolantonio cites research showing that excessive sugar increases blood pressure and the risk of metabolic syndrome more than salt does.
• He references studies published in journals such as JAMA Internal Medicine and American Journal of Cardiology, adding weight to his claims.

Salt and Physical Performance: What’s the Connection?

The book also explains how the right amount of salt can help athletes and active adults avoid hyponatremia (dangerously low sodium), maintain electrolyte balance, support healthy muscle function, and, in some cases, even reduce the risk of muscle cramps and back pain.

• For many working adults in Garland—from warehouse staff near I-635 to those enjoying a weekend at Lake Ray Hubbard—adequate salt intake is vital for staying hydrated and preventing fatigue.

Should You Change Your Salt Intake?

This information from “The Salt Fix” is not a final answer for everyone.  Managing high blood pressure or any health condition requires a personalized approach.  This blog is only a review of Dr. DiNicolantonio’s arguments and evidence—not medical advice.  Always consult with your own medical doctor before altering your diet or salt intake, especially if you have a history of blood pressure or kidney issues.
