Key Takeaways
- Monitor APOE status – Get genetic testing to understand your APOE variants (e.g., APOE4) as they significantly impact Alzheimer’s risk.
- Optimize cholesterol levels – Maintain healthy LDL and HDL levels to support brain lipid homeostasis and reduce Alzheimer’s risk.
- Prioritize omega-3 intake – Consume EPA/DHA-rich foods or supplements to support brain lipid metabolism.
- Reduce refined carbs and sugars – These negatively impact lipid metabolism and may exacerbate Alzheimer’s risk.
- Exercise regularly – Physical activity improves lipid metabolism and brain health.
Bottom Line
Get your APOE status checked, optimize cholesterol and omega-3 intake, and maintain an active lifestyle to reduce Alzheimer’s risk.
