Why should you have an understanding what low nutrient density and high nutrient density means?
|
So you can easily control calorie intake
Have longer periods of satisfaction Harder to over eat Higher total essential intake more nutrients per volume |
|
|
What is calorie density?
|
Ratio of calories to actual weight of food
|
|
|
What foods have high calorie density? and what foods have low calorie density?
|
High-Cookies,bacon,butter,crackers
Low-fresh veggies, broth based soups fresh fruits and chicken breast |
|
|
Finding a long-term set of dietary habbits should be based on the intersection of what three goals?
|
performance, health and body composition
|
|
|
Does focusing exclusively on body composition when making nutrition choices lead to improved health? Give an example why or why not
|
No, If you focus on strictly loosing weight, you could not be getting the proper nutrients and effecting your seratonin levels which effects your mood.
|
|
|
What is the purpose of an ergogenic aid?
|
To provide short term results.
|
|
|
Why would your client be interested in ergogenic aids?
|
To get results fast.
|
|
|
What is medical nutrition therapy? Why should you be concerned with it?
|
Prescribing a diet to cure or prevent a disease. We are not licensed to prescribe medical nutrition.
|
|
|
What is metabolism?
|
The sum of reactions that take place to build up and break down the body
|
|
|
What is the highest level of organization of the body?
|
a organism.
|
|
|
In order, provide the level of organization that relate to the body
|
organism>organ system>organs>tissue>cell>organelle>molecule>atom
|
|
|
Give an example of each level of organization: organism, organ system, organ, tissue, cell, organelle, molecule, atom
|
organism-Human
Organ system- Urinary system organ- liver tissue-Connective tissue cell-blood cell organelle-mitochondria. molecule-chromosones with DNA Atom-as low as it gets. |
|
|
What are the 11 organ systems?
|
digestive, reproductive, nervous, respiratory, immune, circulatory, endocrine, urinary, skelitor, integumentary,muscular
|
|
|
What does the digestive system do?
|
Break down and absorb food
|
|
|
What does the reproductive system do?
|
For smashing bitches
|
|
|
What does the nervous system do?
|
electro-chemical cellular communication signals
|
|
|
What does the respiratory system do?
|
Getting rid of Co2 and bringing in O2
|
|
|
What does the immune system do?
|
This system is responsible for defending the body against pathogens, tumor cells and other foreign invaders
|
|
|
what does the circulatory system do?
|
transporting hormones, enzymes nutritions and other chemicals throughout the body
|
|
|
what does the endocrine system do?
|
produce hormones. this system is responsible for chemical celluar communication within the body. not to be confused with electro-chemical communication
|
|
|
what does the urinary system do?
|
responsible for storing, producing, and eliminating urine
|
|
|
what does the skeletal system do?
|
supporting the body
|
|
|

|
Provides protection to the body from external damage. skin hair nails ect
|
|
|
What does the muscular system do?
|
provide movement
|
|
|
What are the 4 major tissue types in the human body?
|
muscle
nervous epithelial connective |
|
|
What is epithelial tissue?
|
tissue composed of cellular layers that will act to protect surfaces of the human body
|
|
|
what is connective tissue?
|
tissue with multiple cells and fibers that helps to protect and support
|
|
|
What is muscle tissue?
|
contractile tissue consisting of cells that contract when stimulated
|
|
|
What is nervous tissue?
|
tissue capable of conducting impulses that help to connect and communicate signals to other parts of the body
|
|
|
what are enzymes?
|
cells in the human body produce these to help catalyze chemical reactions
|
|
|
How does nutrition play a role in how our enzymes function?
|
Enzymes depend on proper nutrition to function and catalyze chemical reactions
|
|
|
Why do people respond differently to the digestion and absorption of certain foods?
|
People have genetic differences. inside each cell is the nucleus which houses our genetic code (dna) everyones DNA is different
|
|
|
List seven different organelles
|
plasma membrane, cytoplasm, mitochondrion, nucleus, endoplasmic reticulum, golgi apparatus, lysosome, peroxisome
|
|
|
What is the plasma membrane?
|
A lipid bilayer that is permeable to certain compounds that contains the cell (acts like the protective wall to keep the bullshit out)
|
|
|
What is the cytoplasm?
|
The gel that holds the organelles together. (organelle)
|
|
|
What is the mitochondrion?
|
Provides energy for the cell and produces ATP (organelle)
|
|
|
What is the nucleus?
|
It is the largest organelle that is located in the central portion of the cell housing the DNA typically wrapped up in chromosomes. What we eat can influence our DNA (organalle)
|
|
|
What is ER and Golgi apparatus?
|
When the nucleus sends out a message to make protiens the ER and Golgi takes the message and makes it. The two types are smooth and rough
|
|
|
What are lysosomes and peroxisomes?

|
|
|
Why are transport proteins important?
