Unit 25 Flashcards
Is WATER an essential nutrient?
Yes
Functions of water
- Maintenance of body temp
- Hydration
- Removal of waste products
- Participation in energy formation
- Major source of flouride
Daily Fluid Recommendations vary on what factors?
- Diet
- Activity
- Temperature
- Humidity
Beverages = __% of Water
95%
Fruits + Veggies = __% of Water
75-90%
Meats = __% of Water
50-70%
10 Factors that increase Water Needs
- Diseases that mess with water balance
- exercise
- forced air environments
- heated / de-hydrated environments
- increased dietary fiber, sugar, salt, protein
- drugs
- pregnancy
- Prolonged sickness
- Surgery / blood loss
- young / old age (cannot regulate body temp)
Dehydration
reduces ability to dissipate heat causing increased body temperature
decreases oxygen consumption
Temperature and L of Water Lost
Lower the temperature = Less water lost
Higher the temperature = Higher water lost
- sweating causes you to lose 1-2 L / hour
Water created by
Metabolism
Foods
Liquids
__ of Weight loss = __ of Sweat
1 kg of Weight loss = 1 L of Sweat
Electrolyte replacement
- Can happen in a meal (1-3g)
- Salt tablets not recommended
- K+ losses easily replaced by fruits and veggies
3 Components to Electrolyte Replacement
- Volume
- little by little, to prevent bloating - Temp
- colder better for ingestion - Composition
- 6-10% of glucose to provide energy
Mineral Water
- underground
- reservoirs between rocks
- dissolved minerals
Spring Water
- springs that form pools or streams
Sparkling Water
- carbonated
- true seltzers are naturally carbonated
- commercial addition of pressurized CO2
__% of bottle water is purified bottle tap water
45%
Environmental component (%) to the following cancers:
Endometrial
Stomach
Prostate
Endometrial = 100% Stomach = 72% Prostate = 58%
