Q

Type 2 diabetes. What are the 3 mechanisms? What is it strongly correlated with? What is a significant risk factor? Why?

A
  1. insulin resistance = produce insulin but cells dont recognize insulin
  2. insulin insensitivity = insulin binds to receptor but no response
  3. pancrease overwhelmed and does not produce insulin
  • strong correlation to lifestyle
  • overweight/obese increases risk (constant state of inflammation)

Q

Visceral vs. subcutaneous fat (which is worse?) Why? (2)

A
  • visceral (around the organs = central obesity) worse

Extreme obesity equals the risk of death from smoking

A

24
Q

Most men have ___ shape fat distribution and femals have ___ shape. Which shape do we want?

A
  • most men have android, females have gynoid shape

- want gynoid shape (away from organs

25
Q

When do you have metabolic syndrome? What are symptoms? (4)

A
  • waist greater than 35/40 = have metabolic syndrome

- elevated bp, elevated blood glucose, increase triglyceride, blood LDL cholesterol

26
Q

What is cadiovascular disease? This includes these 2 specific diseases.

A
  • Disease of heart and blood vessels

- This includes Atherosclerosis and Hypertension

27
Q

true or false

Heart is one of the least regenerative organs.

A

true

28
Q

Cardiovascular diseases have a strong link to ___ & ___ behavior.

A

Strong link to dietary behavior (high intake of saturated and trans fat and high cholesterol levels) and sedentary behavior

29
Q

When cardiac muscl damaged, not heart tissue but ___ tissue replaces, causing the organ to be inefficient.

A

connective tissue (scar tissue)

30
Q

What can happen to hearts?

A
  • overworking can make the heart flabby or tough

- hardening of arteries take place at branch points (fat/clots like to accumulate here)

31
Q

What are nonmodifiable (3) and modifiable risk factors (1) to developing cardiovascular disease?

A
  • nonmodifieable: age, sex (males more at risk until females go thru menopause then femles more at risk), genetics
  • modifiable: type 2 diabetes
32
Q

What is ATHEROSCLEROSIS? What determines how much takes place? (2) What increases ATHEROSCLEROSIS risk (2)

A
  • Hardening of the arteries
  • hi trans fat/LDL, sedentary
  • high blood triglycerides, low HDL
33
Q

True or false

Everyone has signs of atherosclerosis

A

true

Start developing atherosclerosis in late teenage years, but how it progresses is up to you!

34
Q

What is the mechanism of ATHEROSCLEROSIS? (4 steps)

A
  1. HDL takes fat to tissue for use as energy. whats bad is lots of LDL or trans fat attaches to HDL so cannot be delivered to tissues
  2. oxidized LDL free radical & burries itself in blood vessel
  3. body sends macrophages to destroy it but turns into a foam cell (useless macrophage cell) which turns into a clot
  4. Ca, Mg, P moving in blood held up by foam cells & deposit there (mineralization)
35
Q

ATHEROSCLEROSIS

What is

  • stationary clot
  • clot that travels and can become stuck
A

Thrombus (thrombosis) – stationary clot

Embolus (embolism)

36
Q

What can thrombosis (ATHEROSCLEROSIS) cause? (2)

A
  • can decrease blood to/from heart can lead to heart attack

- can cause strokes

37
Q

What is shown to reduced blood clot development?

A

Omega-3 fatty acids

38
Q

increase pressure behind a clot makes it pop, causes internal bleeding

A

aneurysm

39
Q

What is hypertension? What is systolic and diastolic pressure? What is the goal numbers for each?

A
  • high bp
  • systolic pressure = Pressure created as heart (ventricles) contract (goal 120mmHg)
  • diastolic pressure = Pressure created as heart (ventricles) Relax (80 mmHg)
40
Q

True or flase

bp needs to be collected multiple times over time

A

true

41
Q

Wha is cardiac output? What increases blood pressure/hypertension risk? (5) What is the biggest factor contributing to high bp?

A

-Heart rate x stroke volume = amt of blood ejected by heart per min

  • the more blood ejected from heart, more blood in blood vessels
  • the longer the blood vessel, more time it has to get in contact with something and get stuck
  • taller individual (increased resistance)
  • viscosity thicker the harder to move
  • constriction (increase resistance/pressure) BIGGEST FACTOR
42
Q

Which 2 organ systems control hypertension (bp)?

A

nerv and endocrine system controls homeostasis

43
Q

This race have more risk of developing hypertension than this race

A

african americans more at risk than caucasian americans

44
Q

What is the 2nd leading cause of death in the US?

A

cancer

45

A 
mitotic phase
apoptosis (uncontrolled replication)
genetic (DNA)
free radicals (carcinogen)
mass of abnormal tissue
46
Q

What are the risk factors of cancer? (6) What types of cancers? What decreases the risk? (3)

A

Increase

  • obesity (all cancers)
  • alcohol (in mouth, throat, esophagus, colon, liver, breast cancers)
  • trans/sat fat
  • charred red meat
  • preservatives like nitrate in meat
  • age risk factor because chronic disease (but children can have it)

decrease

  • PA
  • fiber rich food (colorectal cancer)

A

anorexia nervosa, bulimia nervosa, binge eating disorder

48
Q

What is anorexia nervosa? What does it do to the body? Does it cause death?

A
  • self-starvation
  • nutrient deficiency so body slows down all chemical reactions, shuts down organs if left untreated
  • yes
49

True or false

bulimia nervosa is More prevalent than anorexia nervosa

A

true

50
Q

What is bulimia nervosa?

A

Binge eating and purging (self-induced vomiting/diarrhea due to guilt)

51
Q

What is binge eating disorder? What emotion is associated with it?

Q

What is the female triad? What population does it usually affect? (2)

A
  • eating disorder causes amenorrhea (lack of hormones/no period) and osteoporosis
  • often in gymnasts and dancers
54
Q

How can eating disorders be prevented? (4)

increase PA, positive eating behavior, have positive body image, talk thru

What is CAM? What is the principle behind it? What kinds of activities does it include? What is the problem with CAM? Why? What does aloe help with? Cinnamon? Ginger?

A
  • Complementary and alternative medicine

  • herbal medicine & accupuncture
  • Lack of knowledge → due to lack of funding bc most research comes from pharmaceutical companies
  • aloe helps with burns
  • cinnamon increase activity of insulin
  • ginger GI tract issues
56
Q

What is nutritional genomics?

A

how nutrition affect our DNA

57
Q

What is nutrigenomics and nutrigenetics?

A

Nutrigenomics

  • food affects genes (gene expression an dmutation)
    ex. vitamin A causes replication of DNA

Nutrigenetics

  • genes influence nutrients (nutrient absorption, use, tolerance)
