General Functions of Water:Water is the most important nutrient; made

of oxygen and hydrogen. After air, water is the most important factor

to human life. Accounting for approximately 60% of your

body weight, humans can exist for several weeks without food, but only a few days without water.

Water makes up the majority of the fluids in and around cells and other structures. • Water’s most important functions include:

• Hydration: the maintenance of optimal levels of water for health.

• Transportation: used in the transportation of bodily fluids (i.e. blood plasma).

• Temperature regulation: water is used to lower body temperature (i.e. secretion of sweat).

• Lubrication: water is the primary component of saliva, making it possible to swallow dry foods.

• Solvent: known as the “universal solvent”, water is used by the body to dissolve solutes in the blood.In relation to weight loss:

• Water can prevent overeating when consumed before a meal (Davy 2008).

• Dehydration can trigger hunger, resulting in overeating.

Calculating the amount of Water you need in a day!You need approximately 30 ml of water per

kilogram of bodyweight per day. This would be approximately 2.3 litres of water for a 77 kg (170 lb) person.

1 Kg = .45 lbsCalculate how much water you need for one

day!

Ways to obtain water:Plain water is the form that most people

should consume the majority of their water. Water within other beverages is much less desirable and should be minimized compared to plain water. Non-nutritious: Soda, alcohol, etc. should be

reduced or eliminated.Semi-nutritious: Tea, coffee, fresh squeezed

juices, etc., are acceptable in small quantities (1-2 servings per day)

Remember our digestion diagram?

Where is water used?

Page 12: Macronutrients :  Water

The Scoop on PoopThe useable nutrients are absorbed into the

bloodstream from the small intestine. The leftover material continues on to the large

intestine, where fecal matter (feces, or “poop”) is created. The large intestine absorbs water and some electrolytes from the leftover material, and that water is returned to the body to prevent dehydration.

If too much water is absorbed, constipation occurs; if too little water is absorbed, diarrhea occurs.

Once the feces are created, they pass to the colon, where they are stored. When the colon is full, a signal is sent to your brain telling you that you need to relax your anal sphincter and release the feces.
