Sodium and chloride (together forming common table salt) are essential for maintaining fluid balance and extracellular volume. While the body needs these electrolytes, excessive sodium is a primary driver of high blood pressure and cardiovascular disease .
Expert reports suggest limiting sodium to below 2,300 mg per day to reduce the risk of chronic conditions like hypertension. Summary of Daily Reference Values Target (Adult Men) Target (Adult Women) Total Water Adequate Intake (AI) 3.7 Liters 2.7 Liters Potassium Adequate Intake (AI) Sodium Adequate Intake (AI) Sodium CDRR (Limit) < 2,300 mg < 2,300 mg Dietary Reference Intakes for Water, Potassium,...
Maintaining these levels requires a diet rich in whole foods and adequate fluid intake, especially for those who are physically active or exposed to high heat. Sodium and chloride (together forming common table salt)
High potassium intake is associated with a reduced risk of stroke and kidney stones. However, most people in North America fall short of these targets. Increasing intake through potassium-rich foods—such as leafy greens, beans, and potatoes—is generally recommended over supplements, as the kidneys effectively excrete excess potassium in healthy individuals, making a "Tolerable Upper Intake Level" (UL) unnecessary for the general population.
