Water

Water is the most important nutrient we consume everyday of our lives. It is the solvent for the foods we eat, transporting nutrients and helping to metabolize or assimilate them throughout our body. It holds the products of digestion in solution, carrying them through the intestinal wall into the blood stream. The blood-plasma  which is 90% water then passes through the human vascular system (arteries and veins), carrying nutrients to cells and waste product through the skin, kidneys, and bowels. The main source of energy for the pressure to perform these tasks is the heart, which pumps in excess of 2000 gallons of blood through the body per day.
