Flashcards in 1st test Deck (47):
1

most common source of Raffinose ans Stachynose

Legumes- soy bean, peanuts, peas, beans

2

Raffinose

Glucose-galactose -sucrose trisaccharide

3

Stachynose

Adds a second galactose to raffinose

4

Essential fatty acids

linoleic acid(omega 6) and linolenic acid(omega3)
needed for immune function.
contains fatty acid in a place we cant place

5

Omega 3 fatty acid(

linolenic acid.
Is primarily from fish oil as EPA and DHA
also canola oil, soy boy and olive oil
make eicosanoids

6

signs an sympotoms of essential fatty acid deficiency

flaky itchy skin
anemia
dirreahae
infection
retarded growth and wound healing

7

what does eicosanoids do

make prostaglandins, leukotrienes, thromboxanes

8

Function of cholesterol

essential in cell membrane
produce in liver
found only in animal products
forms important hormone
precursor of bile salts

9

lipoprotien lipase

breakdown triglyceride into chylomicrons

10

DV is responsible for

comparing foods (not amount u should eat)
no RDA for fat

11

a healthy adult will have what kind of nitrogen balance

neutral

12

hydrogenation

making of trans fatty acids from oils adding hydrogen

13

dangers of trans fatty acids

heart disease
High LDL
Low HDL
2% causes a 23% increase in cardio disease. thats less than 1 g is recommended

14

salatrim

Benefat contains short chain fatty acid... so are not well absorbed..
so people have GI problems with it

15

olestra

yields no calories
fatty acids link to sucrose to make a sucrose polymer
not digested by enzymes or bacteria
over digestion can cause loose stool

16

Soluble fibers

Slows gastric emptying, slows glucose absorption

17

glycemic index

Breaks down food into good carbs are bad carbs based on rate of increased blood glucose
good for diabetics

18

GERD

Gastrointestinal re-flux disease.
Not just acid reflux duodenal contents (shit) comes up too... bile amalyse ect.

19

Steatorrhea

diarhea cause due to lipd absorption problem

20

monosaccharides

glucose frucrose galactose

21

oligosaccharides

Raffynose & stachyose

22

cholesterol levels

ideal is below 200

23

Melamine

fake protien causes sickness

24

protien nutrition depends on

Amount consumed
digestibility
amino acid mix

25

what test measure protein quality

Chemical Score(CS)
Protien Efficacy Ratio(PER)
Bio Value (BV)
Protein Digestibility Corrected Amino Acid Score(PDCAAS)

26

CS

Chemical score= mg of amino acid per grams of protein /mg of amino acid per grams of ideal protein

27

PER

Protien Efficacy Ratio= Weight gain/total protein intake

28

BV

Biological value:= what was eaten less urine and fecal
the most acurate measure of protien value

29

PDAAS

Protien digestibility corrected amino acid score= Chemical Score X digestible factor
Not used for pregnant women or infant below 1

30

which protien deficiency causes edema

kwashikor

31

Arginine

and essential amino acid only when protein demand is high

32

PKU

phenylketonuria= genetic disease with the conversion of phenylalanine to tyrosine.

33

what is the AHA fat limit

30%

34

non-caloric fat substitute

olestra

35

RDA

Recommended Dietary Allowance- Quality date made to establish level of value for 97% of population

36

high fiber is considered

5 g or more per serving

37

Sorbitol

cariogenic sugar

38

protein balance=

nitrogen in vs nitrogen out

39

dental effects of celiac disease

Looks like over flouridation

40

omega 6

make arachidonic acid
found in vegetable oil only 1 tablespoon a day

41

metabolic syndrome

CHD, HT, type 2 diabetes
primary factors: insulin resistance , abdominal obesity
secondary factors: physical inactivity aging, hormonal imbalance

42

avicil,Z-trim,oat-trim

cellulose -grain husk derivatives
is a fat substitute

43

Simplesse

milk globuls (whey)
better mouth feel than carbs
fat substitutee

44

resversatrol

Stimulates production of SIRT1

45

soluble fibers

pectins,gums,mucilages

46

insoluble fibers

cellulose hemi cellulose , lignin

47

health consequences of diebetes

retinopathy,Kidney Disease,neuropathy, amputation
