Dietary Reference Intakes For Water, Potassium,... «2024»

About 80% of this intake typically comes from beverages, while the remaining 20% is derived from water-dense foods like fruits and vegetables. These levels are designed to prevent acute dehydration and ensure proper plasma osmolality , the primary indicator of hydration status. Potassium: The Counterbalance to Sodium

Water is the body's primary constituent, essential for regulating temperature, transporting nutrients, and maintaining cellular function. Rather than the common "eight glasses a day" rule, the National Academies set an AI for —which includes moisture from all beverages and foods. Men (19–30 years): 3.7 liters (approx. 125 oz) daily. Women (19–30 years): 2.7 liters (approx. 91 oz) daily.

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

The Dietary Reference Intakes (DRIs) are scientific standards used by health professionals to assess and plan diets for healthy individuals. When evidence is insufficient to set a Recommended Dietary Allowance (RDA), an is established based on observed average nutrient intakes in healthy populations. For water and potassium, these AIs serve as vital targets for maintaining physiological balance and long-term health. Total Water: Hydration Beyond the Glass
