Omega-3s and brain health: what the science really says | Dr. Bill Harris & Prof. Sarah Berry

In this episode of the ZOE Science & Nutrition podcast, Jonathan is joined by Dr. Bill Harris, a leading expert on omega-3 fatty acids, and Prof. Sarah Berry to explore the links between omega-3s and brain health. They discuss what omega-3 fatty acids are, differentiating between ALA (plant-based) and EPA/DHA (fish-based), and why the latter are more bioactive. They address the prevalence of omega-3 deficiency in the West and the importance of achieving an optimal Omega-3 Index. The conversation covers the impact of omega-3s on heart health, including debunking myths around cholesterol and atrial fibrillation, and delves into the emerging research on omega-3s and brain health, including their potential role in reducing the risk of dementia, anxiety, and depression. They provide actionable advice on how to increase omega-3 levels through diet and supplementation, recommending oily fish like salmon, mackerel, anchovies, sardines, and herring, and aiming for a daily intake of 1,000 milligrams of EPA and DHA.
