## Описание

This clip is from episode #380 ‒ The seed oil debate: are they uniquely harmful relative to other dietary fats? | Layne Norton, Ph.D.


In this clip, they discuss:


- Seed Oils Are a Modern Addition – Highlights that humans did not evolve consuming meaningful amounts of seed oils, yet today they may account for 10–15% of total calories for some people
- Modern Diets Are Fundamentally Different – Notes that even diets perceived as “natural” today differ dramatically from historical human diets
- Evolution Prioritizes Reproduction, Not Longevity – Explains that biology is optimized for passing on genes, not for maximizing health deep into old age
- Chronic Disease as a Modern Outcome – Suggests higher cardiovascular disease rates occur partly because people now survive infections, violence, and early death
- Evidence Over Evolutionary Guesswork – Concludes that dietary decisions should be guided by total evidence and net health effects, not by whether something existed in the past

### Segment 1 (00:00 - 02:00) []

We did not evolve in an environment where people were consuming seed oils in much quantity at all. And yet today, people are probably getting 10 to 15% of their total calories from these things, right? — Some people do. Yeah, for sure. — Isn't there just sort of a first principles argument to be made here that says how would that be a good thing? — Even people who think they eat natural these days, the human diet now is not in any way, shape, or form what it used to be. So people will point out, well look at how these vegetables and fruits and plants have been modified. Yeah, but we've done the exact same thing to our animals. If you think having a fatty ribeye is a ancestral diet, it's not. Those cows are much different than they used to be. Take that out of it for a moment, though. The purpose of biology is to pass on your genetic material. There's a reason things start to kind of go downhill after like, you know, age 40 or whatever. It's cuz you're past breeding age. Evolution's done with you. Yes, rates of cardiovascular disease have gone up because you actually have the chance to get cardiovascular disease now because you're not killed by a virus or waring tribe bacteria. I don't think what we think might be natural is necessarily a good barometer for what is conducive to living the longest healthiest life. I think you're kind of getting the order reversed. mankind [clears throat] evolved in this environment where I think one of the reasons we were able to thrive is we were some of the most adaptable creatures out there. Obviously smarter as well but being so adaptable to our environment helped us greatly because we used to think well the strongest survive and really we know it's actually the animals that are most adaptive survive. So when we look at all the data together, the question really shouldn't be did we evolve eating seed oils or this. The question should be based on the best evidence we have, what is the overall net effect of these
