Good morning, my name is Alan Ta and I’m a Registered Dietitian participating in the “Lunch and Learn” program today. On this presentation, I would like to discuss the main point, “Water: An Overlooked Essential Nutrient”; and reveals the importance of water in the body, hydration and unrecognized nutrients the body needs. The body depending on gender is composed of 65 to 50 percent water, with 85% in the brain, and 15% in the bones(Kreutler & Czajka-Narins). Different cells in the body require water to function properly, blood is composed of water which carries nutrients throughout the body, lubricates joints and helps with gastric juices (Kreutler & Czajka-Narins). Without proper hydration, these vital organs and bodily functions will be reduced. Dehydration through exercise must be addressed or a person can pass out and in extreme cases die.

To address the concern of hydration and nutrition, this firm is considering three beverage types: water, Gatorade or Powerade. According to the Mayo Clinic (2012), men should consume 3 liters of water daily and women should consume 2.2 liters. During regular short bouts of exercise 1.5 to 2.5 additional cups of water are required (Mayo Clinic, 2012). In terms of long bouts such as marathons the additional of sodium filled sports drinks is required (Mayo Clinic, 2012). These types of beverages help to prevent hypernatremia, which can be fatal. The number of these drinks consumed can be determined by the number of hours that individual is engaged in extreme exercise.
