According to general guidelines, what is the Adequate Intake (AI) for fluid intake for adult men?

The Adequate Intake (AI) for fluid intake for adult men is approximately 3 liters per day. This guideline accounts for all beverages and food moisture content consumed, which can vary greatly based on individual needs, climate, activity level, and overall health.

This recommendation is based on studies assessing hydration and ensuring that men meet their daily fluid dietary needs to support bodily functions such as digestion, temperature regulation, and nutrient transport. Additionally, maintaining proper hydration is essential for overall health, enhancing physical performance, and cognitive function. The consensus among health authorities is that 3 liters (or about 13 cups) is a reasonable target for fluid intake for most adult males under typical conditions.
