Kaç Tane Omega Yağ Asitleri Vardır?

Memeli dokusunda dört ana omega (ω) yağ asidi ailesi bulunmaktadır: omega-3, omega-6, omega-7 ve omega-9. 1

Omega Yağ Asidi Aileleri

Dört Ana Aile

  • Omega-3 (ω-3): Soğuk su balıkları, kanola yağı, soya fasulyesi, ceviz, keten tohumu ve bunların ürünlerinde bulunur 1

    • Ana formları: EPA (eikosapentaenoik asit), DHA (dokosaheksaenoik asit), ve ALA (α-linolenik asit) 2, 3
    • ALA (18:3n-3) esansiyel bir yağ asididir ve diyetle alınması gerekir 1

  • Omega-6 (ω-6): Diğer tüm bitkisel yağlarda baskın olarak bulunur 1

    • Ana formları: Linoleik asit (18:2n-6) ve araşidonik asit (20:4n-6) 1, 3
    • Linoleik asit esansiyel bir yağ asididir 1

  • Omega-7 (ω-7): Memeli dokusunda bulunan dördüncü poliansatüre yağ asidi ailesidir 1

  • Omega-9 (ω-9): Ağırlıklı olarak zeytin ve zeytinyağında bulunur 1

    • Ana form: Oleik asit (18:1) 1, 4
    • İnsanlarda endojen olarak sentezlenebilir, bu nedenle kısmen esansiyel kabul edilir 4

Önemli Klinik Noktalar

Esansiyel Yağ Asitleri

  • İnsan sağlığı için esansiyel kabul edilen yağ asitleri ilk iki aileden gelir: omega-3 ailesinden 18:3 (ALA) ve omega-6 ailesinden 18:2 (linoleik asit) ve araşidonik asit (20:4) 1

  • Bu esansiyel yağ asitleri vücutta sentezlenemez ve diyetle alınması zorunludur 1

Kardiyovasküler Sağlık İçin Öneriler

  • American Heart Association tüm yetişkinlerin kardiyovasküler sağlık için haftada en az iki kez yağlı balık tüketmesini önerir 2

  • Genel kardiyovasküler sağlık için günde 500 mg EPA+DHA veya haftada en az iki kez yağlı balık tüketimi önerilir 5

  • Koroner kalp hastalığı olan hastalar günde 1 gram EPA+DHA tüketmelidir 5, 2
