Is salt healthy?
The low-salt consensus rests on epidemiological associations, not controlled mechanistic evidence, and multiple researchers argue the optimal intake is a U-shaped curve — too little is as dangerous as too much. Gary Taubes and Nina Teicholz have both documented how the original salt-restriction science was methodologically weak and institutionally entrenched. Weston A. Price research and James DiNicolantonio's work on 'The Salt Fix' argue that unrefined mineral-rich salt is not only safe but essential at intakes far above official guidelines.
Evidence
- Cardiologist James DiNicolantonio, in 'The Salt Fix,' marshals evidence that the average human kidney is designed to retain sodium aggressively, and that sub-1,500 mg daily recommendations push many people into a hormonal stress state — elevating renin, aldosterone, and adrenaline — that is itself cardiovascular risk.
- Nina Teicholz, in 'The Big Fat Surprise,' places the salt narrative alongside the cholesterol and fat campaigns as a case study in how weak associational science becomes policy through institutional momentum rather than replication.
- Weston A. Price Foundation researchers emphasize the distinction between refined industrial salt stripped of trace minerals and unrefined salts — Celtic grey salt, Himalayan, Real Salt — which retain magnesium, potassium, and 80+ trace minerals that modulate the sodium-potassium pump critical to cellular voltage.
- Jack Kruse further argues that sodium drives structured water formation in the exclusion zone around cells, linking adequate salt intake to mitochondrial and neurological function in ways entirely outside the blood-pressure-only framing of conventional nutrition science.
- He cites the PURE study (Prospective Urban Rural Epidemiology), which tracked over 100,000 people across 18 countries and found the lowest cardiovascular mortality in participants consuming 3,000–5,000 mg sodium daily, with increased risk below 3,000 mg as well as above 6,000 mg.
