🥑 Omega-3, Omega-6 and Omega-9: The Ideal Balance in the Diet

How the fatty acid ratio affects health

Omega-3, omega-6 and omega-9 are fatty acids with different effects. Let's look at what ratio is considered ideal and how to achieve it in the diet.

🔬 What are omegas

Omega-3 and omega-6 are essential PUFAs (polyunsaturated fatty acids) that the body cannot synthesize itself. Omega-9 is a monounsaturated, non-essential one.

  • Omega-3 — essential, anti-inflammatory.
  • Omega-6 — essential, energy source.
  • Omega-9 — monounsaturated.
  • Balance affects inflammation.

⚖️ Omega-3 and omega-6 balance

Omega-6 (linoleic acid) in excess promotes inflammation, while omega-3 counteracts it. The ideal ratio is 3:6 = 1:1–1:4, but in a typical diet it is 1:15–1:20.

  • Omega-6 — pro-inflammatory in excess.
  • Omega-3 — anti-inflammatory.
  • Ideal 1:1–1:4.
  • In the diet often 1:15+.
Important: reducing omega-6 (vegetable oils) matters more than supplements.

🥑 Omega-9

Omega-9 (oleic acid) is a monounsaturated fatty acid from olive oil and avocado. The body can synthesize it itself, so the balance matters less.

  • Oleic acid.
  • Olive oil, avocado.
  • Non-essential.
  • Good for the heart.

How to improve the balance

  • Less sunflower and corn oil.
  • More fish, flax, walnuts.
  • Olive oil for omega-9.
  • Omega-3: 1–2 g EPA/DHA/day.

Important: the goal is to lower omega-6, not just add omega-3.

💡 Practice

  • Fatty fish 2 times a week.
  • Replace sunflower with olive oil.
  • Add flaxseed and walnuts.
  • Monitor inflammation (hsCRP).
  • For supplements — verified quality.
