Optimising your omega 3 intake | Dr Bill Harris | The Proof Podcast EP 208

Published 2022-05-31
In Episode 208, I’m joined by expert researcher Dr Bill Harris to discuss the relationship between omega-3 fatty acids and human health.

Increasingly, online nutrition conversation is moving away from scientific literature and is more heavily influenced by marketing and controversial claims for personal gain. Whether people are making these statements to grow their online community or capitalise on a financial opportunity, omega-3 and omega-6 fatty acids are yet another topic surrounded by bold claims.

Dr Bill Harris is a leading researcher in omega-3 fatty acid research. As the author of more than 300 scientific papers on fatty acids and health, he brings decades of researched knowledge to the conversation. He is a true expert in field who has been researching these fats for decades, offering a thoroughly informed and genuinely scientific perspective.

In this episode, you’ll learn about the different types of dietary fats and why saturation is important in terms of human health. We cover the connection between cholesterol, fat saturation, and heart disease; the benefits and potential concerns of consuming omega-3s; supplementation guidelines; omega-6s and inflammation; the difference between adequate and optimal intake; and much more.

Specifically, we discuss:

    How does this channel not have more subscribers? Yes, the episodes are long, but they are chock full of great conversation and poignant questions.
  • @postpunkjustin
    I've been going through the whole backlog of the podcast and this is easily one of my favorite episodes so far. I loved learning more about what omega-3 fatty acids do and how, but having a specific evidence-based supplementation plan is absolutely priceless. Cheers Simon, keep up the fantastic work!
  • @jp7357
    You are an excellent interviewer … you never try to impress the audience with your obviously deep knowledge and let your guest show their expertise. I also like the way you dot go off on non plant foods. I’ve added fatty fish back into my plant based diet due to protein requirement (120g-150g) while still trying to maintain a 500kcal deficit ..
  • @simashakila
    Could you invite Dr. Brooke Goldner next? She uses the high Omega 3 and low Omega 6 approach in her protocol reverse autoimmune conditions in her patients.
  • @azdhan
    Many thanks to you and your host for this. It really helps cut through a lot of conflicting, confusing, and contradictory information I have come across on this issue.
  • @71taeus
    Such an excellent episode. It answered so many of my questions and had me checking my supplements cupboard; happy to find I had the ideal omega3s, just need to adjust my dosage slightly. I would love to have heard his thoughts on recommendations for pregnancy and was disappointed this wasn’t covered. Excellent interview as usual Simon
  • @mayurim9839
    I always learn something new when listening to Dr Harris on a podcast, he's really good at explaining things! Also, the questions asked were really helpful and ones that I haven't heard posed in a such a way to him before. Learnt a lot. Thank you.
  • @ImpulseFortune
    I wish someone would mention cost in these discussions. Ballpark figures, ~500 mg per day of epa+dha (roughly what most governments recommend on average) will run you about $0.10 a day in the form of fish oil but $0.50 a day in the form of algal oil. In other words to get what he is recommending (~1000 mg a day) you are asking people, on the vegan side, to literally spend a dollar a day to achieve that. That is… not a negligible amount of money for a significant fraction of the population, even ignoring the third world.
  • @kdcoys3
    Thanks for diving into the science and chemistry of Omegas!
  • @woofinu
    Thank you for a very detailed, nuanced discussion
  • @joannsmith9
    I think one of the brilliant minds in the science/longevity field is the Wellness Messiah. I’d love to see him get the attention he deserves. He did a deep dive into the Sinclair/Brad controversy regarding resveratrol. His medaresearch was phenomenal and his conclusions fascinating.
  • @user-ry7wf3df9h
    I hope you know how important what you are doing is for the public. Even if someone doesn’t understand all the intricacies of the research- it helps people understand HOW to look at research and all the factors that go into a study. Thank you for all the thoughtful important information and challenging different “camps” in the nutrition world ❤
  • @bettyle88
    This is one of my favorite health channel, I like the deep dive. May we have a topic about dry skin, especially postmenopausal dry skin, and hypothyroidism dry skin? Thanks!
  • @cadupradoo
    Nice, Simon! Awesome, actually! I did miss some of the possible disadvantages of fish consumption due to PCBs, mercury, etc.
  • @hrc6408
    Great episode.. loved this and thanks for doing topics like this that are not just about being vegan. I am predominantly plant based but I eat fish and take omega 3s. It’s what I feel is best for me.
  • @astonuk9403
    Definitely need a part two, maybe Dr B could muster up some research on dietary omega 3 and fatty acids on the gut microbiota. It appears omega 3 intake also alters the gut microbiome composition and some of its cardiovascular effects appear to be potentially mediated by its effect on gut microbial fermentation products indicating that it may be a prebiotic nutrient.
