cAI = Adequate Intake. The observed average or experimentally determined intake by a defined population or subgroup that appears to sustain a defined nutritional status, such as growth rate, normal circulating nutrient values, or other functional indicators of health. The AI is used if sufficient scientific evidence is not available to derive an Estimated Average Requirement. The AI is not equivalent to a Recommended Dietary Allowance.

cal activity and environmental (e.g., heat) exposure, on a day-to-day basis fluid intake, driven by the combination of thirst and the consumption of beverages at meals, allows maintenance of hydration status and total body water at normal levels.

Approximately 80 percent of total water intake comes from drinking beverages and water. While consumption of beverages containing caffeine and alcohol have been shown in some studies to have diuretic effects, available information indicates that this may be transient in nature, and that such beverages contribute to total water intake.

While the AI is given in terms of total water, there are multiple sources of such water, including moisture content of foods, beverages such as juices and milk, and drinking water. While all of these
