NSD 225 FINAL EXAM QUESTIONS WITH CORRECT
ANSWERS
/. Examples of nonscientific methods - Answer-✅Intuition: what people think or feel is
true
Conventional wisdom: what most believe
Personal experience: in daily life
Observations: what you see others doing
/.What to look for in sources - Answer-✅Written or checked by experts
Benefits and risks
No financial gain
/.who to ask for nutrition advice - Answer-✅Registered dietitian nutritionists (RDN) or
Nutrition Scientists
/.In Vitro - Answer-✅Test tube
Easy cheap quick BUT may not relate to people and can't study whole foods
/.In Vivo - Answer-✅Animals
Easy cheap and whole foods BUT may not apply to people and artificial environments
/.human observation - Answer-✅Big in size and health outcomes measured BUT only
correlational, no cause and effect
/.human intervention - Answer-✅Control and experimental group, cause and effect BUT
small number of participants, expensive, doesn't apply to everyone
/.BMI - Answer-✅body weight(kg) / height(m)^2
/.Drawbacks of MBI - Answer-✅Can have same BMI and height/weight but different
body composition
BMI developed for perfect average man
/.Ways to find body fat % - Answer-✅Dual energy Xray: scan to show lean vs fat
Underwater weight: displacement
Bod Pod: air displacement
Skinfold measurements
, Bioelectrical Impedance Analysis
/.Subcutaneous fat: - Answer-✅Can squeeze, keeps warm
Pear shape: subcutaneous, butt and thighs, low risk
/.Visceral Fat - Answer-✅in/around organs, chronic risk
Apple Shape: fat builds above waist, visceral, high risk
/.how to measure waist - Answer-✅measure around umbilicus, not narrowest part
Increased chronic risk of BMI > 30
Waist > 40 and 35
/.how to tell if weight loss needed - Answer-✅clinical signs (blood pressure, blood
glucose levels, cholesterol)
/.processed foods and weight gain - Answer-✅Processed foods easier to eat and don't
make us full
Spike blood sugar and insulin levels
/.diet - Answer-✅typical foods eaten by a person
Fad diets not sustainable
Undieting: permanent changes to eating patterns, increase nutrient dense food intake
/.adipose tissue - Answer-✅Stored fat to prevent starvation, keep us warm, protect
organs
Stored in triglycerides within cell
/.energy balance - Answer-✅Equilibrium: adipose cells stay same size
Positive balance: cells grow when eating more than using | Lipogenesis
Negative balance: cells shrink when eating less than using | Lypolysis
/.Lypolysis - Answer-✅triglycerides broken down and used for energy
Between eating, blood glucose levels drop and glucagon tells cells to do lipolysis
/.Lypogenesis - Answer-✅when fat deposited into triglycerides in adipose cells
When eating, blood glucose spikes and insulin tells cells to do lipogenesis
/.Glycemic load - Answer-✅quantity and quality of carb in a meal
How much glucose in it
/.Glycemic index - Answer-✅ratio of blood glucose response to pure glucose
How fast glucose absorbed
High: watermelon & crackers
Low: spinach & apples
