Video summary

In this discussion, Dr. Rhonda Patrick addresses whether low omega-3 levels are comparable in severity to smoking cigarettes, citing a pivotal study from Dr. Bill Harris's group at the Fatty Acid Research Institute. The core metric highlighted is the Omega-3 Index measured in red blood cells rather than plasma, as RBCs provide a long-term marker reflecting intake over 120 days compared to the short-term snapshot of plasma levels. The data reveals that individuals with an index below 4% face significantly higher all-cause mortality rates, whereas those maintaining an index above 8%, such as populations in Japan who consume more seafood, enjoy increased life expectancy. When stratifying this data by lifestyle factors like physical activity and BMI, the results show a stark correlation: non-smokers generally live longest, while smokers with low omega-3 levels have the shortest life expectancies. Notably, smokers who maintained high omega-3 indices through diet or supplementation exhibited similar longevity to non-smoking individuals with adequate levels, suggesting that severe deficiency in these fatty acids may be as detrimental to mortality risk as smoking itself regarding cardiovascular health. Dr. Patrick clarifies that while observational data establishes a strong correlation rather than definitive causation due to potential healthy user bias, the biological mechanisms supporting omega-3s are robust and independent of lifestyle factors like exercise or diet quality alone. Smoking is widely recognized for increasing lung cancer risk in a dose-dependent manner, but its impact on cardiovascular disease appears non-linear; even minimal smoking can drastically elevate heart attack risk. Omega-3 fatty acids serve as a primary defense against this specific threat by reducing inflammation, which is a major driver of cardiovascular disease. Randomized control trials have demonstrated that purified forms of EPA and DHA significantly lower the risk of dying from cardiovascular events compared to placebos. Therefore, while one cannot rule out confounding variables entirely in observational studies, there is clear evidence that optimizing omega-3 status provides critical protection against heart disease regardless of other health behaviors. For individuals struggling with seafood consumption due to cost or cooking difficulties, Dr. Patrick recommends supplementation as a viable strategy to reach the target Omega-3 Index of 8%. She notes that physicians often prescribe ethyl ester forms like Vascepa (pure EPA) or Lesa (DHA and EPA), typically at doses around four grams daily, but suggests that two grams per day is an effective starting point for most people to bridge the gap from a standard American diet level of roughly 4% up to the optimal range. This dosage is considered safe for the general population and can effectively raise red blood cell levels within three months. When selecting supplements, consumers should look for third-party testing data regarding purity and oxidation; specifically, products with total oxidation below 10 are preferred to avoid consuming rancid fats that could negate health benefits. The quality of a supplement is further determined by its molecular form, primarily triglyceride or ethyl ester. Triglyceride-form omega-3s mimic the natural structure found in fish and offer superior bioavailability compared to purified ethyl esters, though some manufacturers reconvert ethyl esters back into triglycerides for enhanced absorption regardless of cost. Crucially, Dr. Patrick emphasizes that these supplements must be taken with a meal containing fat to ensure proper absorption; taking them on an empty stomach renders the dose largely ineffective. For those attempting to meet their needs through diet alone, wild Alaskan salmon is highlighted as one of the best sources due to its low contaminant levels like mercury and PCBs per ounce. However, because cooking methods can degrade heat-sensitive omega-3s and dietary intake may not be sufficient for everyone without supplementation, a combined approach often yields the most realistic results: consuming fish meals twice weekly while taking approximately two grams of high-quality triglyceride-form supplements daily to maintain optimal blood levels.

are low Omega-3s worse than smoking cigarettes um I don't know that they're worse so omega-3 fatty acids are in you know they're essential for many things and um I think you're referring to one specific study that came out of uh Dr Bill Harris's group he's the head of the fatty acid Research Institute and he's actually the pioneer of the omega-3 index test which is how you should measure your omega-3 levels um there measured in our red blood cells rather than which you'll 99% of the time find if you get a omega-3 test it's plasma levels so red blood cells take about 120 days to turn over so it's a long-term marker of your omega-3 whereas if you go and get a omega-3 plasma test it's kind of like what did I eat for dinner in the last week right so you you may have had a bunch of salmon but maybe you don't usually eat salmon so so anyways the omega-3 index is a way to measure omega-3 levels and he had done a study looking at omega-3 levels and what's called all cause mortality so people dying from all sorts of non-accidental causes cardiovascular dis disease is always at the top of the list because that's pretty much what everyone's dying of that's like the number one cause of uh death in most developed countries and so um he was looking at all cause mortality and correlating that with the omega-3 index which essentially is measuring omega-3 fatty acid levels and um what he found was that so people that have a low omega-3 index so that would be 4% or less H and then comparing it to people that had a high omega-3 index so that would be 8% or higher so people that had the high omega-3 index had a fiveyear increased life expectancy compared to people with the low now people in the United States on average have about a four to 5% omega-3 index so it's pretty pretty standard pretty standard I would say in terms of like what people in the US have in terms of their omega-3 versus Japan where they eat a less Seafood their omega-3 index is like 10 % so and they have a 5-year increased life expectancy by the way compared to people in the United States um so what he also did uh him and his his colleagues looked at they stratisfied the data and looked at other factors physical activity you know BMI smoking and this is where it got super interesting because um and I I I just the graph of this data does it like more Justice you know because you can visually see it but he looked at all cause mortality and people that like lived the longest were of course the high omega-3 index with no smoking right so like non-smokers they had the longest life expectancy and then people with the lowest life expectancy were smokers with a low omega-3 index but then when he looked at people that smoked but had a high omega-3 index either they're eating a lot of fish or supplementing they had the same life expectancy as people with low omega-3 but didn't smoke so in other words having a low omega-3 index was like smoking with respect to all cause mortality and that's you know and of course I get all the smokers out there going oh so all I have to do is supplement with omega-3 I'm like no no no no no that's the wrong way to think about it you know I think I think most people now know smoking is terrible for your health and it and it goes back to this idea this framework that I like to think about nutrition which is what do we need right instead of like always focusing on what to avoid because if you focus on what to avoid you still may not getting what you need to run your metabolism to run you know neurotransmitter synthesis and all of that so omega-3 fatty acids are hugely important for many things and we could talk hours for that but with respect to smoking it's really quite you know it's it's kind of AST astounding when you just look at that graph and they're like overlaid where you're like oh wow non-smokers are with omega-3 are living as long as smokers with high omega-3 do you think that this is a direct cause of the Omega-3s or is there some healthy user bio that's Upstream from the kinds of people who are the kinds of people that are like people that will have omega-3s in their diet great question so um with this type of data which is observational data it's always a correlation so you can never you know definitively say it's cause right a causation so yes there could be it could be a healthy user bias there were other factors that were accounted for but I will say this smoking everyone thinks about smoking and lung cancer or like cancer right risk right actually the biggest problem with smoking is heart disease it is a huge it's so when you so here's the thing that I like to think about like with respect to smoking and disease risk smoking in a dose dependent manner will increase your risk for lung cancer so in other words the more cigarettes that you smoke the higher the risk of cancer but it's not a linear increase with respect to cardiovascular disease and heart attack risk so you can just have a little bit of cigarettes and your your heart disease risk skyrockets and omega-3 is one of the biggest things that it protects against is heart disease right doctors prescribe it so there's been randomized control trials where people are given high do omega-3 purified omega-3 um in the form of either EPA which is one of the Marine sources or a combination of DHA and EPA um and and and a variety of Studies have shown that like heart attack risk um risk of of dying from card card vascular disease is dramatically lower in people that are given Omega-3s compared to a placebo so you know the fact that the the nonsmokers with um a low omega-3 index are probably affect it's affecting their cardiovascular health inflammation is a big also a Big Driver of cardiovascular disease and Omega-3s are really good at lowering inflammation in many different ways so yeah to sort of the long-winded you know answer to your question is no you can't definiely say that healthy user bias isn't involved but there's a mechanism that we could see how it would work there is and you know again there is adjustment for other health factors so you would think that that would show up let's say that someone goes I hadn't even thought about Omega-3s I should probably optimize those what's the 020 of getting good Omega-3s in your diet someone might struggle with seafood it's kind of hard or expensive to cook at home where would you send them for getting it from diet getting it from supplementation what do they need to know so I think um I talked about the omega-3 index and again you want to get 8% or higher it's always good to measure things but there's been studies done where people with a low omega-3 index so the standard American basically 4% if you give them about two grams a day of Omega-3 they can raise their omega-3 index from 4% to 8% so that would be a supplemental form pretty two gram so I'll just give you to give you some perspective you know Physicians prescribe um what's leesa which is a DHA and EPA ethylester form we can talk about different forms of Omega-3 um of omega3 and they also prescribe uh vispa which is a highly pure EPA form and they prescribe them at gr um in the gram dose of four grams per day so that's twice as much as two grams a day which so what I'm getting at it's a fairly safe dose and um so two grams a day can raise people from 4% to 8% I think that's a really good sort of just starting point or the average person now I take experimentally higher doses but but you know I think generally speaking it's pretty safe for most people to take two grams a day and you're going to get that high Omega 3 index at 8% where are they going to go how are they going to assess without getting some Norwegian farmer that's squeezing fish into a barrel and and doing it holistically himself what can you say about assessing the quality of I I even remember cod liver oil tablets back in the day there's all sorts of uproar before there was even a podcasting Universe to kind of scrutinize it what do people need to know if they're choosing their omega-3 supplement I think choosing omega-3 supplement is um we actually have a lot of data now a days and we have access to that data quite easily because there's a lot of third party testing sites that go out and they just randomly get fish oil supplements off the grocery store shelves and they say I'm going to take this supplement I'm going to measure important things I'm going to measure the concentration of the Omega-3s EPA and DHA is the concentration in there what is stated on the bottle I'm going to measure you know so fish it's being isolated it's like it's an oil it's in the fat right so um fish also have contaminants they have pcbs they have mercury among others and so measuring those contaminants is important because fish oil is generally purified but you want to make sure a good job was done so those contaminants are measured and then um oxidation so Omega-3s are a polyunsaturated fatty acid prone to oxidation and so you don't want to get something that has an oxidation greater than 10 so anything greater than 10 of total oxidation you want to avoid because it's like consuming rancid fat right rancid lipids like you don't want to do that so so you those things are all measured and um there's sources out there so consumer lab is a you know thirdparty testing site that you know they just there's a lot of affordable brands that you can find because some supplements are just very expensive so I do like to kind of send people there because I have no affiliation with consumer lab by the way I just like that I I like I use them so I like that you can go and find a a pretty decent quality fish oil supplement if you're a data nerd like me you can take this up a level and you can go to the international fish oil standard site ifos they just I mean it's like data party like they give you so much data but like you have to like know what to do with it so they measure all these things but like and everything else right um and they also tell you the form it's in so I mentioned ethylester for the prescription form there's also triglyceride form those are the two main forms that you can find fish oil supplements or Omega-3 supplements in and um generally speaking triglyceride form is is the most bioavailable triglyceride form is what is the form if you're eating fish the Omega-3s are in triglyceride form when the Omega-3s are purified they take it out of the triglyceride form and they purify it and it's in an ethylester form some companies then reify it back into that form to make it Supreme and more bioavailable both pure and bioavailable exactly but not everyone does that and so if you get an ethylester form which is what is prescribed most people that are getting prescription form of Omega-3 to help prevent cardiovascular disease they're taking aester form that's what I've got the thing to know is you have to take it with a meal and preferably with a higher fat meal because it is absorb it you will absorb so little if you're taking it on empty stomach it's very important and um I didn't want to get into all the new ones but I mentioned two grams a day of Omega-3 will raise your omega-3 index from low to high right 4% to 8% well if you really kind of look at the form people were taking triglyceride versus ethylester you know they had to take you know less of the triglyceride form to get there but so I like to just average it out and say two but um so if you can get triglyceride form it's it's a great form to get how much salmon or Cod or halbot do I need to eat per week if I was going to try and get this through my diet right I mean that's that's a question that I don't have empirical data to back up but Al so so here's my sort of thoughts on that um I do think that wild Alaskan salmon is one of the best sorts of Omega-3 because um that is a fish that has a very low level of contaminants like Mercury um pcbs per gram or per ounce I guess is usually measured per ounce of of the fish right so salmon would be a great source now how much of that do you have to eat uh it's really you know depends on the cooking method like how how cooked was it because you can degrade some of the Omega-3s are somewhat heat sensitive so I don't know how much you You' have to do a test right so you'd have to say okay I typically eat salmon two nights a week or three nights a week and and then you want to wait 120 days right because it takes that long for your red blood cells to turn over okay I know here's the pro Ronda just just tell me how much salmon I need to eat come on please I I don't know I a week at least at least I would I would say you probably have to supplement on top of that I don't know that twice a week is NE necessarily going to go from 4% to 8% got you but if you were to do you know I would imagine a lot of the people that care about this listening to this protocol will think right I'm going to find a good quality uh low oxidation triglyceride version of Omega-3s that are responsibly sourc that I like the look of I'm going to take two Gams of that per day and I'm probably going to try and have some sort of fish meal twice per week does that seem realistic that's absolutely that's kind that's what I do I mean I that's what I I do I do up the dose a little bit more but like I said you know I like eat it like I take it throughout the day the Omega-3s in other news this episode is brought to you by element stop having coffee first thing in the morning your adenosine system that caffeine act on
