The Mind-Blowing Science of Omega-3 Fatty Acids for Heart Health, Brain Health and Longevity (Rebroadcast)

I think they're about 65 years old when we screened them, when we measured their omega-3 levels. And then we followed them up for about 10 or 12 years. So between, say, 65 and 75. Some people died, some people didn't, right? Some people were smokers, some people weren't smokers.

And we did all the statistics and found that the people who lived the longest were non-smokers and had the highest omega-3 levels, okay? And contra that, the people who died the soonest, most likely to die, were smokers and those with the lowest omega-3. And in the middle, I think is the area you're kind of talking about,

If you had high omega-3 and were a smoker, you had about the same risk of death as if you were a low omega-3 and non-smoker. It's kind of in the middle. So they were roughly equivalent in a way in terms of risk prediction. I've got to be careful with this.

Because some people will take this and say, okay, all I got to do is eat more fish, take some fish oil pills, and then the smoking I'm doing right now is not going to bother me. I wouldn't go that far. But we all have some sense of how much smoking increases your risk for bad outcomes. And I just want to get people to realize that the omega-3 level is kind of in the same category.

It's on the other side, of course. Or I guess you'd say a low omega-3 is kind of like being a smoker in terms of your risk. But fair enough. That's a good way to explain it.

It was. I mean, when I first saw that graph come back from our biostatistics people and showed the lines, the death lines, so to speak, and showing that the omega-3s were basically canceling out the smoking in terms of effect on... I was amazed, too. But they said, trust us, so I trust them. But it's a pretty cool finding.

Yeah, it's a great story. And I assume if you were a typical vegan, you were below our like 4% in that red zone. And that's not a good place to be. What do we know about omega-3 and depression and anxiety? And this is, yeah, there's been quite a bit of research in the area. And it's mixed.
