Which research question would most directly address the uncertainty that high protein intake may displace other important nutrients at the population level?

A regional nutrition program has limited budget. Compare the likely population-level impacts of two options: (A) distributing low-cost energy-dense but low-protein food (high caloric porridge) versus (B) distributing smaller quantities of fortified food higher in protein and micronutrients. Which is more likely to reduce both wasting and edema and why?

Critically evaluate the statement: 'Because existing observational studies link high protein with improved weight loss, no further research is needed on long-term health tradeoffs.' Which rebuttal is most defensible?

Which mechanism best explains why insufficient dietary protein leads to peripheral edema in kwashiorkor?

What combination of clinical features would prompt classification as marasmic kwashiorkor rather than either marasmus or kwashiorkor alone?

Which concise definition best describes protein-energy malnutrition (PEM)?

In a population survey, two malnourished children are identified: Child A with severe wasting and Child B with edema and fatty liver. Break down the physiological mechanisms that explain why Child B develops edema while Child A does not.

Which of the following best states the current AMDR for protein and its conceptual rationale relative to total daily calories?

A rural health program can either distribute vouchers for locally available animal-source foods twice weekly or provide bulk fortified cereal every day. Applying principles of PEM prevention, which choice is most likely to sustainably reduce both stunting and kwashiorkor risk and why?

A clinician measures serum albumin of a child with generalized pitting edema and suspects kwashiorkor. If albumin falls from a normal 4.0 g/dL to 1.5 g/dL, explain qualitatively how this change affects oncotic pressure and fluid distribution, and recommend one immediate nutritional priority.
