Part A — Vocabulary (20 points, 2 points each)
Select the single best answer for each question.
1. Appel et al. 1997 DASH trial (foundational anchor) was:
A) A retrospective cohort study B) A landmark controlled feeding trial randomizing 459 adults to one of three diets (typical American, fruits-and-vegetables-enriched, DASH combination) with weight held constant and sodium controlled; produced 5.5-11.4 mmHg systolic BP reductions in hypertensive participants; paradigm-shifting for dietary pattern intervention research over three decades C) An animal study D) A meta-analysis
2. PREDIMED 2013/2018 NEJM (Estruch et al.) tested:
A) Vitamin supplementation B) Mediterranean diet supplemented with extra-virgin olive oil or mixed nuts versus low-fat control diet in approximately 7,500 high-cardiovascular-risk adults; reduced primary cardiovascular events (HR ~0.70) at ~5 years; 2018 re-analysis after methodology critique maintained substantive findings C) Calorie restriction D) Fasting protocols
3. Hall NIH metabolic ward methodology establishes:
A) The 24-hour respiratory chamber measurement of energy expenditure and substrate utilization in controlled conditions B) Free-living dietary assessment C) Animal modeling only D) An obsolete framework
4. Industry-funded nutrition research literature concerns:
A) Are minimal B) Include systematic associations between industry funding and study conclusions favoring funder products (sugar-sweetened beverage industry, food industry, supplement industry research patterns documented by Lesser 2007 PLOS Medicine, Bes-Rastrollo 2013 PLOS Medicine, Mandrioli 2016 systematic review); methodological caution warranted in interpreting funded literature C) Have been definitively resolved D) Apply only to pharma research
5. The NOVA classification system (Monteiro):
A) Classifies foods only by macronutrient B) Classifies foods into four groups by degree of processing — Group 1 (unprocessed/minimally processed), Group 2 (processed culinary ingredients), Group 3 (processed foods), Group 4 (ultra-processed foods); supports population-level dietary epidemiology around food processing as exposure variable C) Has been definitively rejected D) Applies only to manufactured goods
6. Hall 2019 Cell Metabolism ultra-processed food study demonstrated:
A) No effect of food processing B) In a 20-participant inpatient crossover RCT, ad libitum eating of ultra-processed versus minimally processed diets matched on macronutrients, energy density, fiber, and sugar produced ~500 kcal/day higher intake and ~0.9 kg weight gain on the UPF arm over 2 weeks; first inpatient demonstration of processing effect on energy intake independent of macronutrient composition C) Calorie counting works D) Sugar is the only driver
7. Mediterranean diet pattern at intervention research depth:
A) Has no research support B) Is the dietary pattern with strongest cumulative cardiovascular intervention research support — PREDIMED Estruch 2013/2018 NEJM and the broader Mediterranean diet literature; pattern-level rather than nutrient-level intervention C) Is equivalent to low-fat diet D) Has been superseded
8. Loucks energy availability framework (cross-reference Move Master's Lesson 4):
A) Is a body composition method B) Defines energy availability as energy intake minus exercise energy expenditure normalized to fat-free mass (kcal/kg FFM/day); thresholds below ~30 kcal/kg FFM/day produce substantial endocrine disruption; foundational framework for RED-S (Relative Energy Deficiency in Sport) at clinical depth C) Is an obsolete framework D) Applies only to elite athletes
9. NEDA helpline (1-800-931-2237) is:
A) An active 24/7 hotline B) Non-functional — NEDA shut down its helpline in June 2023; replaced with a chatbot that was also taken down for harmful advice. The correct active resource is the National Alliance for Eating Disorders (866-662-1235), weekdays 9am-7pm EST, staffed by licensed therapists C) Newly relaunched D) State-specific
10. USDA Dietary Guidelines for Americans process is:
A) Independent of public comment B) A multi-year scientific advisory committee review followed by Federal Register public comment and federal department-level finalization; methodologically transparent but subject to documented stakeholder influence concerns; foundational federal nutrition policy framework updated every five years C) Determined by single agency D) Has been superseded
Part B — Concept Comprehension (20 points, 2 points each)
Select the single best answer for each question.
11. Food frequency questionnaire (FFQ) methodology at Master's depth:
A) Is bias-free B) Is the dominant population-scale dietary assessment method but carries documented limitations — recall bias, measurement error scaling with quantitative items, day-to-day variability not captured, social desirability bias, validity coefficients ~0.4-0.7 against doubly labeled water gold standard for energy intake; methodologically usable for ranking but unreliable for absolute intake quantification C) Is superior to all other methods D) Has been definitively rejected
12. DASH-Sodium follow-up trial (Sacks 2001 NEJM):
A) Showed no sodium effect B) Demonstrated dose-response BP reduction with sodium restriction in the DASH dietary pattern context — additive to the DASH dietary pattern effect; established sodium restriction at intervention research depth and informed subsequent population sodium reduction recommendations C) Was superseded D) Was contradictory
13. Mendelian randomization in nutrition epidemiology:
A) Uses random food assignment B) Uses genetic variants as proxies for lifetime nutritional exposure to test causal inference where intervention RCTs are infeasible — example: genetic variants affecting lifetime LDL cholesterol exposure used to test the causality of LDL on cardiovascular outcomes (Ference 2017 EHJ consensus); methodologically powerful for some questions, limited by pleiotropy and instrument validity assumptions C) Has no nutritional application D) Is purely observational
14. Selective insulin resistance in metabolic syndrome:
A) Has no clinical relevance B) The state in which hepatic insulin resistance fails to suppress gluconeogenesis (elevated fasting glucose) but continues to activate hepatic SREBP-1c-driven lipogenesis under insulin stimulation; explains the coexistence of hyperglycemia and hypertriglyceridemia in metabolic syndrome; Shulman ectopic lipid framework cross-reference C) Is independent of cellular mechanism D) Has been superseded
15. Mediterranean diet pattern positioning at Master's depth:
A) Stands alone B) Is held jointly across cardiovascular nutrition intervention research (Food L2), metabolic syndrome integration (Food L4), and the dietary pattern framework distinguishing pattern-level from nutrient-level evidence — the strongest cumulative intervention research signal in cardiovascular nutrition at Master's depth C) Has been definitively rejected D) Is equivalent to low-fat dietary recommendation
16. Food systems and ultra-processed food policy at Master's depth:
A) Is purely individual B) Addresses structural drivers — food system industrialization, marketing to children regulatory environment, SNAP eligibility for sugar-sweetened beverages, school meal programs, federal nutrition policy lifecycle, urban food access (food deserts and food swamps) — and the systems framing of population nutrition that complements individual dietary counseling C) Has no public health dimension D) Applies only to outliers
17. Industry influence on dietary guidelines:
A) Is undocumented B) Has been documented through systematic reviews (Mialon 2016 PHN methodology, Cullerton 2016 framework) demonstrating industry stakeholder participation, advisory committee revolving doors, comment-period influence patterns, and post-publication communication strategy; methodologically transparent process operates within these documented influence patterns C) Has been resolved D) Has been overstated
18. The food-as-medicine framework at Master's depth:
A) Replaces clinical pharmacology B) Describes the prescriptive use of dietary interventions for clinical conditions — DASH for hypertension, Mediterranean for cardiovascular prevention, low-FODMAP for IBS, etc. — within the integrated clinical care framework; complementary to pharmacotherapy, not substitutive for it; one component of the lifestyle medicine framework C) Is unproven D) Applies only to research
19. NOVA classification critique at methodological depth:
A) Has none B) Includes critique that "ultra-processed" is somewhat under-specified at margins, that NOVA conflates degree of processing with nutritional composition in some cases, and that ad libitum effect on intake (Hall 2019) may operate through multiple mechanisms beyond processing per se (energy density, texture, palatability, additive effects); the framework remains the dominant processing-as-exposure variable in population nutrition epidemiology C) Has been resolved D) Has rendered NOVA invalid
20. Personal nutrition integration at Master's depth (Food L5):
A) Is prescriptive B) Integrates clinical nutrition translation, food systems framing, eating disorder vigilance, and the Loucks energy availability framework into the personal-nutrition decision conversation — held descriptively as graduate-level life literacy, with clinical decisions routed to qualified healthcare providers (registered dietitian nutritionists, physicians, sports medicine clinicians); the personal integration is research-informed not prescriptive C) Replaces clinical care D) Is purely theoretical
Part C — Application (30 points, 6 points each)
Write 5-7 complete sentences with specific reference to chapter content, primary literature citations, and methodological framings where asked.
21. DASH trial methodology and pattern-level intervention framing. Walk the Appel et al. 1997 NEJM DASH trial methodology (3-arm controlled feeding RCT, 459 adults, three diets with weight held constant and sodium controlled, BP primary outcome). Identify what the trial demonstrated (5.5-11.4 mmHg systolic BP reduction in hypertensive participants from dietary pattern alone) and how this established dietary pattern as the methodologically appropriate intervention unit. Position DASH as the foundational anchor of the Master's chapter and articulate the parallel to Lam 2016 (Light), ARDSNet 2000 (Breath), and Heerspink 2020 (Water) as Master's clinical-translational anchors.
22. Hall 2019 ultra-processed food inpatient crossover study. Walk the Hall 2019 Cell Metabolism methodology (20-participant inpatient crossover RCT, ad libitum eating, UPF versus minimally processed diets matched on macronutrients/energy density/fiber/sugar). State the findings (~500 kcal/day higher intake on UPF arm, ~0.9 kg weight gain over 2 weeks). Identify why the inpatient controlled-environment design matters methodologically — what confounders does it address that free-living UPF cohort studies cannot? What does the study demonstrate and what does it NOT demonstrate? Apply the five-point framework (design, population, measurement, effect size, replication).
23. Mendelian randomization and the LDL-cholesterol causality framework. Explain Mendelian randomization methodology (genetic variants as proxies for lifetime exposure to enable causal inference where intervention RCTs are infeasible). Use the LDL-cholesterol cardiovascular causality framework (Ference 2017 European Heart Journal consensus integrating Mendelian randomization, genetic, and pharmacological evidence) as the exemplar. State the methodological limitations (pleiotropy, instrument validity assumptions, lifetime versus shorter-window exposure). Why is this methodology useful where dietary intervention RCTs at hard cardiovascular endpoints are practically constrained?
24. Eating disorder vigilance and crisis resources at Master's depth. A graduate-program peer in a competitive academic environment shows escalating food rigidity, daily weighing, body image distress, and exercise compulsion. Walk the recognition framework at Master's depth (Loucks energy availability cross-reference where applicable, clinical recognition versus self-diagnosis, descriptive-not-diagnostic stance). Name verified currently-active crisis resources: 988 Suicide and Crisis Lifeline (call or text 988, 24/7), Crisis Text Line (text HOME to 741741, 24/7 — not ALLIANCE), National Alliance for Eating Disorders helpline (866-662-1235, weekdays 9am-7pm Eastern, staffed by licensed therapists), SAMHSA National Helpline (1-800-662-4357, 24/7) for substance use treatment referral. Identify the older NEDA helpline (1-800-931-2237) as non-functional since June 2023 and explain why it must not be cited.
25. Food systems policy and industry influence at Master's depth. Apply the food systems policy framework at Master's depth to one structural intervention surface — sugar-sweetened beverage taxation (Mexico 2014 policy, Berkeley 2016, Philadelphia 2017 evaluations), school meal program reform, ultra-processed food regulation in marketing-to-children contexts, or SNAP eligibility for sugar-sweetened beverages. Address: the public health rationale, the documented industry response pattern, the methodological evidence base for the intervention's effects, and the limitations of individual-counseling-only framings of population nutrition. Cross-reference the wellness-industry-research-gap pattern that appears across the Master's tier — how does food systems policy operate at a different scale of intervention than individual dietary counseling?
