Water: an essential but overlooked nutrient

Area of Science:

• Nutrition Science
• Public Health

Background:

• Water is an essential nutrient vital for human life and physiological functions.
• Recommended daily fluid intake varies by sex, with men needing approximately 2,900 mL and women 2,200 mL.
• Surveys suggest a portion of the population may suffer from chronic mild dehydration.

Purpose of the Study:

• To highlight the health implications of chronic mild dehydration.
• To emphasize the role of fluid and water consumption in disease prevention.
• To encourage dietitians to promote and monitor adequate hydration in clients.

Main Methods:

• Review of existing literature and consumption surveys.
• Analysis of factors contributing to dehydration.
• Examination of research linking fluid intake to various health outcomes.

Main Results:

• Dehydration as low as 2% body weight loss impairs physiological and performance responses.
• Adequate fluid intake may reduce the risk of urinary stones, certain cancers, and obesity.
• Fluid consumption impacts overall health, particularly in the elderly.

Conclusions:

• Chronic mild dehydration poses significant health risks, affecting physiological function and disease susceptibility.
• Promoting adequate fluid and water intake is essential for public health.
• Further research is warranted to fully understand the impact of chronic mild dehydration on health and disease.
