Fast response (3 things that happen to body)
Dilate pupils; Constrict blood vessels (GI tract & skin); Dilate blood vessels (skeletal muscles)
3
Slow response
Hypothalamic-pituitary-adrenal axis
4
Positive short term effects of cortisol
#1. Mobilize energy reserves (increase glucose and fatty acid release)
5
Chronic cortisol leads to what about blood vessels
up stiffness
6
% of GDP healthcare NOW
$$ per capita NOW
20%
$10,000
7
What are the 3 spheres where Americans get care?
#1. Popular = treatment which is community based (fam)
#2. Folk = ethnic/religious healers
#3. Professional
8
Gov insurance % of US pop
30%
9
Triple aim is
1. up experience of care
2. up pop health
3. down cost
10
All country’s systems have (2 things)
-comprehensive
-similar salaries for all docs
11
Canadian health system: all medically necessary care provided WITHOUT “”
Co-pays
12
2 features of patient centered med home
-personal doc
-whole person orientation
13

US average
Rank in 20s
20s
15
RI ranks best in what (2 things)
Ranks #1 for immunization among children
Ranks #1 for im. Among teens
16
3 priorities of RI DOH
#1. Address social determ
#2. Eliminate health disparities
#3. Ensure access to care
17
name of proposed solution (geographic areas)
Health equity zone
18
Many states are showing (up/down) in childhood obesity
Down
19
Obesity is BMI over #
30
20
Aging pyramid trend
1980 to now
Before: base is young
Now: the base balloons up, so that the end result is an upside down heart
21
example of Polysaccharide
amylose starch
22
Carbs (3 types)
Mono-saccharides
Disaccharides
Polysaccharide
23
examples of lipids (2)
fatty acid
acyl-glycerol (triglyceride)
24
fatty acid principle things (chemically)
methyl group on one end
carboxyl group on other
25
types of lipids
FA
acylglycerol
sphingo-lipid
steroid
26
amino acids consist of
amino + carboxylic acid groups
27
nitrogen containing comp (list them)
#1 AA
#2 purine, pyri-midine, pyri-dine
#3 nucleoside
#4 nucleotide
28
define nucleoside
tide
side = nitrogen containing ring plus sugar, like ribose
tide = nucleoSIDE with a phosphate attached to the sugar
29
list AA that are essential
I like light that tries making home very pretty
isoleucine
leucine
lysine
threonine
tryptophan
methionine
histidine
valine
phenylalanine
30
during a 24 hr fast, energy needs are met by
-consumption of liver glycogen
-conversion of protein to glucose via gluconeogenesis
31
during longer periods of fasting, remaining energy needs are supplied by
-production of ketone bodies from fatty acids
-by muscle protein, which is a substrate for gluconeogenesis
32
3 ways metabolic regulation is done
-availability of substrates
-covalent modification of enzymes
-altered synthesis/breakdown of enzymes
33
"" is the primary storage form of carb in plants
starch
34
soluble fiber "" (slows/fasts) digestion
slows
35
source of insoluble
soluble
insoluble
-bran
-whole grain
soluble
-pectin-containing foods (fruit, legume)
36
define glycemic index
blood glucose response to a carb
37
what is the primary utility of GI
predict glucose response in ppl with diabetes
38
adj essential means
must be acquired thru diet
39
Total energy expenditure =
Resting energy expenditure (60%) + thermic effect of food + calories expended in physical activity
40
Thermic effect of food = what
10%(TEE)
41
Body water makes up ?/70 kg male
40 kg
42
If a person of normal weight has free access to water BUT nothing to eat, how long can they survive?
2 month
43
Mono-saccharides (3 things)
Glucose
Fructose
Galactose
44
Glucose dietary source (2)
Fructose dietary source (2)
Fruits
Corn syrup
Fruit
High fructose corn syrup
45
Galactose dietary source
Milk
46
Why is galactose weird
Not found free in nature
47
What are the di-saccharides
Sucrose
Lactose
Maltose
48
Define glycemic index
Area under the curve
Blood sugar over time after you consume something
49
The more saturated, the “” the melting temp
Higher
50
Define trans fat
-un/sat
-contains (cis/trans) (iso/poly) fatty acid
Unsaturated fat that contain trans isomer fatty acids
51
Trans fat pro (2)
1) less prone to oxidation
2) higher burning temp
52
the force that moves water (to side with more solutes) is called
osmotic pressure
53
water req #
1 mL / 1 Cal
54
read: reduce water loss by keeping wet clothes close to skin
-
55
pH equation
-log [H+]
56
normal blood pH

57
