NSD 225 exam 2 study guide questions with
correct answers
What |is |the |scientific |method |based |on? |Why |is |this |beneficial?
-Based |on |organized |observations |and |logical |thinking. |This |is |beneficial |because |the |more |
evidence |we |have, |the |wiser |we |can |be |when |making |food |decisions.
Who |would |be |a |good |person |to |get |nutrition |advice |from?
Registered |dietitian |nutritionists(RDNs)
Nutrition |scientists
Trained |in |nutrition |research
What |are |the |advantages |and |disadvantages |of |animal |studies?
Advantages: |easier, |cheaper, |faster |than |human |studies. |Disadvantages:may |not |apply |to |
people, |need |follow |up |human |studies, |artificial |diets |and |environments
What |are |the |different |types |of |research |studies? |What |kind |of |relationships |do |each |
demonstrate?
Test |tube |studies-
performed |in |vitro.
Vitro |studies |are |only |performed |on |single |nutrients |or |small |groups |of |cells |and |not |on |living |
animals.
, Quickest |and |easiest |to |perform
May |not |show |what |happens |in |a |human |body
Easy, |cheap, |fast, |few |variables
Animal |studies-
performed |on |living |animals, |in |"vivo".
Animals |can |tell |more |about |whole |foods |and |diets |without |the |need |for |human |subjects
Can |study |whole |foods
They |are |easier, |cheaper, |and |faster |than |human |studies
Effects |on |animals |may |not |always |apply |to |humans
Human |observational |studies-
Apply |directly |to |humans |and |generate |a |lot |of |data
Look |at |lots |of |people |and |many |different |health |outcomes
Can |only |show |correlation |not |causation |because |you |observe |and |do |not |intervene
Results |can |be |misleading |or |hard |to |interpret
Can |take |a |long |time
Human |intervention |studies-
experiments |in |which |researchers |intervene |and |change |people's |diets |to |see |how |it |affects |
their |health
Most |accurate |and |can |prove |cause |and |effect
Costly |and |take |a |lot |of |time |to |perform
Look |at |small |numbers |of |people
Results |may |not |apply |to |everyone
What |is |a |health |claim? |What |should |you |watch |out |for |with |health |claims?
Unlike |structure-function |claims, |health |claims |relate |the |intake |of |a |nutrient |to |a |particular |
disease |state |or |other |health |condition, |rather |than |just |the |general |function |of |the |body
