Malnutrition and Diet-Related Health
Explaining how dietary patterns can contribute to undernutrition, excess and named health risks without reducing disease to one cause.
How to prepare for the written examination
Move from person or food context to relevant evidence, scientific or nutritional principle, consequence and justified decision. Complete all practical and NEA work only through authorised centre arrangements.
Core concepts
Concept 1
Malnutrition includes deficiencies, imbalances and excesses, not only insufficient total food.
Exam cue: State the dietary exposure, body mechanism and possible health consequence.
Concept 2
GCSE content links diet with obesity, cardiovascular health, blood pressure, bone and dental health, iron-deficiency anaemia and type 2 diabetes.
Exam cue: Use contributes to risk rather than proves or causes in every individual.
Concept 3
Risk is usually multifactorial; a strong explanation identifies the dietary mechanism while acknowledging relevant non-dietary factors.
Exam cue: Distinguish prevention-oriented population advice from diagnosis or treatment.
Risk pitfalls and guardrails
Equating malnutrition only with low body mass.
Guardrail: Do not replace explanation with a memorised food fact, undated public-health figure or a practical project that belongs to NEA.
Claiming one food directly causes a complex disease.
Guardrail: Do not replace explanation with a memorised food fact, undated public-health figure or a practical project that belongs to NEA.
Confusing iron-deficiency anaemia with lack of calcium.
Guardrail: Do not replace explanation with a memorised food fact, undated public-health figure or a practical project that belongs to NEA.
Memory anchors
Malnutrition
Poor nutritional status caused by inadequate, excessive or imbalanced intake or use of nutrients.
Dietary Risk Factor
A pattern or exposure associated with greater probability of a health outcome.
Cardiovascular Health
Health of the heart and blood vessels, influenced by several dietary and non-dietary factors.
Iron-Deficiency Anaemia
Reduced oxygen-carrying capacity associated with inadequate available iron, loss or impaired use.
Multifactorial Condition
A health outcome influenced by multiple interacting dietary, biological, behavioural and environmental factors.
Checkpoint rule
Do the check-up only after you can summarize each concept in one sentence and identify one dangerous pitfall from memory.
