Why athletes often show low omega‑3
William Harris explains athletic demands may lower omega‑3 levels and athletes may need higher intakes to maintain levels.
Confusion around omega-3, seed oils and the omega-6:3 ratio has fuelled major misconceptions. In this episode, Angela speaks with leading researcher Dr William Harris to clarify what the evidence really shows about omega-6 fats, seed oils and long-chain omega-3s - and why much popular advice is outdated.
They explore why the omega-6:3 ratio doesn’t predict inflammation, why EPA/DHA deficiency is so common, and how omega-3 status affects mental health, pregnancy, cognition and cardiovascular resilience.
