Broadcast date: August 13, 2026

Hosts: Dr. Bill Harris & Kelly Patterson

Guest: Dr. Barry Sears

Dr. Barry Sears joins Dr. Bill Harris and Kelly Patterson to explore how omega-3 fatty acids, diet, and insulin intersect with inflammation and metabolic health. From EPA and DHA to brain health and the Omega-3 Index, Dr. Sears shares his perspective on using nutrition to help control—and resolve—inflammation.

Hosts: Dr. Bill Harris & Kelly Patterson

Guest: Dr. Aleix Sala-Vila

In this episode, Dr. Bill Harris and Kelly Patterson interview Dr. Aleix Sala-Vila about the relationship between omega-3 fatty acids, brain health, and dementia. Dr. Sala-Vila discusses recent research using UK Biobank data showing that people with higher blood levels of omega-3s—particularly DHA and other omega-3 fatty acids—had a lower risk of developing dementia, including early-onset dementia (before age 65). He emphasizes that these findings are observational, meaning they show associations rather than proof that omega-3s prevent dementia, but they add to growing evidence that maintaining higher omega-3 status may support long-term brain health.

 Broadcast date: June 17, 2026

Hosts: Dr. Bill Harris & Kelly Patterson

Guest: Dr. Aleix Sala-Vila

About this episode: In this episode, Dr. Bill Harris and Kelly Patterson talk to Dr. Aleix Sala-Vila. Dr. Sala-Vila received his PhD in biomedicine from the University of Barcelona in 2004. His research has involved the role of bioactive compounds, especially omega-3 fatty acids from cellular biology to epidemiology, with the ultimate goal of reducing the incidence of chronic disease by optimizing omega-3 status. He has received four postdoctoral fellowships and has published over 45 papers on fatty acids. The main focus of their discussion is a new paper on omega-3 and Alzheimer’s that is causing controversy because it claims omega-3s may accelerate cognitive decline.

 Hosts: Dr. Bill Harris & Kelly Patterson

 Guest: Dr. Simon Dyall

About this episode: In this episode, Dr. Bill Harris and Kelly Patterson talk to Dr. Simon Dyall, who received his BS in biochemistry from the University of Sussex and his PhD in neuroscience from Queen Mary University of London, where his research focused on neuroprotective roles of Omega-3 fatty acids. Dr. Dyall currently leads the Master of Science Clinical Neuroscience program at the University of Roehampton in Great Britain. His research sits at the interface of neuroscience, nutrition, neurobiology, and psychology, also known as nutritional neuroscience. Some of his current projects include exploring the role of polyunsaturated fatty acids and lipid mediators in perinatal health, and a neuroimaging study investigating the therapeutic effects of a high omega-3 fatty acid multi-nutrient supplement on stress and anxiety in young adults.

In this “Ask Us Anything,” we break down the omega-3 & atrial fibrillation (AFib) story (who’s at risk—and who isn’t), explain why the Omega-3 Index target is 8–12%, and cover practical decisions like how to read fish-oil labels (EPA + DHA), choosing sources (fish oil, algal oil, krill, salmon roe, ahiflower), and storing products to limit oxidation.

Omega Matters 2026 is back with Dr. Bill Harris (OmegaQuant) and new co-host Kelly Patterson, RD—answering your most-asked questions about omega-3s, the Omega-3 Index, and what the clinical data actually show.

Topics covered:

• AFib risk: why the signal shows up mainly with high-dose omega-3 in high cardiovascular-risk patients, not typical supplement/food intakes
  
  
• Plaque progression: what the evidence says about slowing coronary plaque growth
  
  
• Brain health: omega-3 status and dementia risk (including early-onset dementia and APOE4)
  
  
• EPA vs DHA (and why “both” usually wins) + common ratio myths
  
  
• Bleeding concerns, SPMs, immunity markers (NLR), dry eye, omega-6 (linoleic acid), and omega-3 for pets

Conflicting Omega-3 Index World Maps (What's Correct?)

OmegaMatters: Episode 48

Hosts: Drs. Bill Harris and Kristina Harris Jackson

About this episode: In this episode, Drs. Harris and Jackson talk about a new world map Omega-3 paper, which prompted the question: “Why do different laboratories provide different values for blood Omega-3 fatty acids, which resulted in two very different world maps of Omega-3 status?” So they dug into the paper to see if they could understand better why they have two very different views on Omega-3 status in the world.
