WHAT ARE BRAIN FATS?

Brain fats refer to the lipids (fats) that make up a large portion of the brain’s structure and function. The brain is about 60% fat, making lipids essential for brain health, cognition, and longevity.

Types of Brain Fats & Their Roles

1. Omega-3 Fatty Acids (DHA & EPA) 
• DHA (docosahexaenoic acid) is a key structural fat in the brain, making up about 25% of total brain fat.
• Supports memory, learning, and mood regulation.
• Sources: Fatty fish (salmon, sardines), walnuts, flaxseeds.
2. Omega-6 Fatty Acids 
• Needed for brain cell communication and inflammation regulation.
• Balance is key—excess omega-6 (from processed foods) can lead to inflammation.
• Sources: Nuts, seeds, vegetable oils.
3. Cholesterol 
• 25% of the body's total cholesterol is in the brain.
• Essential for neuron function, memory formation, and hormone production.
• Sources: Eggs, dairy, healthy fats (but body also makes its own).
4. Phospholipids (Cell Membrane Fats) 🧬
• Important for cell membranes, neurotransmitter function, and brain plasticity.
• Types: Phosphatidylcholine & Phosphatidylserine (PS).
• Sources: Egg yolks, soybeans, fish, liver.
5. Saturated Fats 
• Helps brain cell integrity and energy production.
• Too much may contribute to cognitive decline, but moderate intake is beneficial.
• Sources: Coconut oil, dairy, grass-fed meats.

Why Brain Fats Matter for Longevity

✅ Prevents neurodegenerative diseases (Alzheimer’s, Parkinson’s)
✅ Supports memory, learning, and focus
✅ Reduces brain inflammation
✅ Improves mood & mental health
