Why APOE4 matters
- APOE4 homozygotes (~2% of the population) have ~10-15× elevated Alzheimer's disease risk vs APOE3/3.
- APOE4 heterozygotes (~20% of the population) have ~3× elevated risk.
- Also confers different lipid metabolism — hyper-responsiveness of LDL to saturated fat.
Dietary approach
Prioritise
- Mediterranean or MIND diet pattern.
- Omega-3-rich fish 2–3 times/week.
- Berries and polyphenols and vegetables.
- Legumes and whole grains.
- Extra-virgin olive oil as primary fat.
Minimise
- Saturated fat — APOE4 carriers show larger LDL/apoB increases with saturated-fat intake than APOE3/3.
- Alcohol — even modest intake has larger cognitive-decline signals in APOE4.
- Ultra-processed food.
- Refined carbohydrates and added sugars.
Pharmacotherapy considerations
- Aggressive apoB target (often ~50 mg/dL).
- Consider statin + ezetimibe combination earlier.
- PCSK9 inhibitors if statin+ezetimibe insufficient.
Cognitive-preservation approach
- All lifestyle levers apply: sleep, exercise, hearing, social, cognitive engagement.
- Sleep especially: APOE4 carriers may benefit disproportionately from good sleep hygiene given amyloid-clearance biology.
