Why is water the most important nutrient?
The body is least tolerant of water loss. Lack of sufficient water is called dehydration or hypohydration and can lead to serious consequences. Just 2% water loss will decrease cognitive function, motor control and ability, short-term and long-term memory, attention span, and ability to maintain core temperature (especially when exercising), and increase urinary tract infections and fatigue. One needs to pay particular attention to at-risk populations such as infants, children, the elderly, and athletes.
