  2. Water – • Most important nutrient for survival • Can only survive a 2-7 days without water • No capacity to store extra water • Body weight is approx 45-75% water • 2/3 of water inside cells • 1/3 of water is between cells and in blood

  3. Functions of Water • Needed to carry nutrients to cells and waste products away from cells • The medium in which many chemical reactions take place within our body • Helps body regulate temperature. • Water has a high heat capacity • Will releases heat in perspiration

  4. How much do you need? • AI for total water (beverages and food) is: • Men = 3.7 liters • Women = 2.7 liters • Body weight divided by 2 = oz. of fluids/day • Fatigue is first sign of dehydration • Thirst can masquerade as hunger • Less likely to adjust calorie intake from high sugar drinks (soda, juice, energy drinks)

  5. Sugared Drinks • Study: • 4 weeks -consumed 450 calories of jelly beans. 4 weeks - consumed 450 calories of soda • Results: • Jellybean days, participants compensated by eating approximately 450 less calories • Soda days, participants didn’t compensate.

  6. What increases your water needs? • High amounts of protein, fiber, sodium & alcohol • Strenuous work, athlete, hot weather • Airplane travel • High altitude and low cabin humidity • SF to NY you lose 4-6 c. of water

  7. Water Balance • Body carefully controls water balance • Fluid intakes low: • Kidneys excrete small volume of concentrated, yellow urine • Fluid levels adequate: • Kidneys excrete large volumes of dilute, very light yellow urine • You will feel better and perform better when adequately hydrated

  8. Bottled vs. Tap Water • Bottled water • Regulated by FDA • Tested infrequently • Filtered municipal water (Dasani, Aquafina) • If use, recycle bottle • Tap water • Regulated by EPA • Tested many times/day • Filtered tap water is best!
