Graham's Key takeaways
  • Essential fatty acids (EFAs) are crucial for brain function, heart health, and inflammation control.
  • Omega-3 and Omega-6 fatty acids must be obtained through diet, as the body cannot produce them.

Essential fatty acids (EFAs) are polyunsaturated fats that are vital for maintaining overall health. These fats are categorised into two primary types: Omega-3 and Omega-6, both of which play essential roles in various bodily functions, including brain development, heart health, and immune system regulation.

What Are Essential Fatty Acids?

EFAs are fats the body cannot synthesise on its own and must be consumed through dietary sources. They are important for cellular function, hormone production, and reducing inflammation.

The two main types of EFAs include:

  1. Omega-3 Fatty Acids: Found in fish, flaxseeds, and walnuts, these fats support brain and heart health.
  2. Omega-6 Fatty Acids: Found in vegetable oils and nuts, these fats contribute to immune function and skin health.

Health Benefits of Essential Fatty Acids

  1. Supports Brain Function:
    • Omega-3s, particularly DHA, are critical for cognitive development and mental health.
  2. Promotes Heart Health:
    • Helps lower triglyceride levels, reduce blood pressure, and improve cholesterol balance.
  3. Reduces Inflammation:
    • Plays a role in managing chronic conditions such as arthritis and cardiovascular diseases.
  4. Enhances Skin and Hair Health:
    • Essential for maintaining hydration, elasticity, and overall skin health.
  5. Supports Immune System Function:
    • Helps regulate immune responses and combat infections.
