- American Journal of Clinical Nutrition published the peer-reviewed report (2026; 124(2): 101396), supported by the IAFNS Sodium in Food and Health Implications Committee, which reviewed the evidence behind current sodium and potassium recommendations, practical ways to shift intake, implementation obstacles, and gaps for research and policy.
- Naomi Fukagawa, professor of medicine emerita at the University of Vermont's Robert Larner, M.D. College of Medicine and first author on the report released Nov. 2, 2026, said "It is time to view dietary interventions holistically because food components interact and physiology is integrative across systems."
- Hypertension affects more than 1.28 billion adults worldwide and is a major risk factor for cardiovascular disease, including heart attacks and strokes.
- Potassium counters some of sodium's effects by supporting the kidneys in removing excess sodium through urine, and it contributes to the normal functioning of blood vessel walls — the mechanisms behind the report's blood pressure case.
- Public health guidance should move beyond sodium alone: average sodium consumption continues to exceed recommended levels, while potassium intake remains "far below optimal levels in both developed and developing nations," according to the authors, who still call sodium reduction foundational.
- Potassium-based salt substitutes are presented as a way to reduce sodium while increasing potassium at once, but the report flags a manufacturing limit — too much potassium salt produces an unpleasant metallic taste that affects flavor.
- Patients with kidney disease and people taking certain medications may have difficulty regulating potassium levels, so the authors say supplements and potassium-based salt substitutes should be used with medical guidance.
Why it matters: The report's audience is guideline writers and food manufacturers: hypertension affects more than 1.28 billion adults, potassium intake is far below optimal in developed and developing nations, and potassium-based salt substitutes hit a metallic-taste limit the authors flag as a practical barrier.
