WATER IS THE SINGLE MOST CRITICAL NUTRIENT
The human brain is composed of 95% water; blood is 82% water; the lungs are nearly 90% water. Water is also the single most critical nutrient for health, growth, and development. It is not only the most important nutrient in the body, but also the most abundant. Water is critical to the balance of all the body’s systems, including the brain, heart, lungs, kidneys and muscles.
How important is this balance? A 2% drop in body water can cause a small but critical shrinkage of the brain, which can impair neuromuscular coordination, decrease concentration, and slow thinking. Dehydration can also reduce endurance, decrease strength, cause cramping, and slow muscular response.
Mild dehydration is also one of the most common causes of daytime fatigue. How common a problem is this in the United States? Estimates are that 75% of Americans have mild, chronic dehydration. This is alarming since proper hydration is required for maintaining healthy blood flow, proper kidney function, proper sodium/potassium /electrolyte balance and proper digestive functions.
