AHS18 Michael Rose - Evolutionary Biology of Diet, Aging, and Mismatch.

[@johnthom3342]

I think Michael Rose should replace the word adapt with the more appropriate term “tolerate.” Humans can tolerate the agricultural diet at younger ages, but as we age this unnatural diet causes ever accumulating amounts of damage that result in the manifestation of disease. Switching to a natural carnivorous diet will aid recovery to some extent, but a great deal of unrecoverable damage will have occurred. By age 60 there will be a huge difference in the health of an individual on an unnatural agricultural diet when compared to the much healthier person who has been on a natural carnivorous diet for their entire life.

[@mryan4452]

Riiiiight. Evidence?

[@chinmaykrishna2646]

ok. first thing first. when an evolutionary biologist uses the word adapt or adaptation, what he/she means is a process that results in an organism well suited or well fitted to a particular environment or to particular ecology over EVOLUTIONARY TIME SCALE (over many generations) as a result of natural selection.

[@QuandarNl]

In summary: paleo type diet is the best, especially at later ages. But I advice you to look to PDK diet. It's a little more researched and andvanced than just paleo.

[@overcomer4226]

What is PDK?

[@rckindkitty]

Beautiful talk! Such an important perspective concerning a scientific perspective on what constitutes an optimal diet at a population level. I would love to know if Dr. Rose thinks that a more paleo type diet would also hold added benefit for certain subsets of the population other than the aged. For example, a 25 year old with autoimmune disease or a young adult that has sustained an environmental insult which they might not be genetically well suited for such as some sort of heavy metal toxicity or mold exposure.

u are correct from stuff ive read i have a chronic auto-immune disease (ME/CFS) initially caused by leaky gut from too many antibiotics -.- So ive done YEARS of research into how other people managed to heal themselves, while i was trying to figure out what was causing my version. There's various root causes from Lymes' to Epsein-barr to candida to amalgam to mould etc etc and for many people, just changing their diet alone gave them a return to full health! and nearly always made an improvement if adhered to and im not even talking a proper ancestral diet, just cutting out gluten, milk and junk food im almost one of them XD diet has returned me to 50% after 3 months paleo-keto despite that every month i have broken my diet n fallen out of ketosis. the worst being december when i broke my diet every week

[@jmichaelhayes5974]

Caused me to modify my diet even more so! Excellent.

[@jackschneider5869]

vert excellent presentation

[@nedisings]

Where can I find out about the supplementation results?

[@fingersm]

Dude looks amazing!

[@milknhoney]

Excellent presentation.

[@jarodbarker2375]

I think Mat Lalonde destroyed this argument years ago. This whole argument relies on the assumption that you could never find a better food source. By that standard, we should go back to a primate diet. The one we followed before we started cooking food, the one we followed before eating meat and developing our large brains. See why that is flawed? Obviously, we found a better food source. We started eating meat and then we evolved and developed larger brains. With the flies, who cares if they went back to the old diet. That assumes you couldn't find a better food or develop a better food, and so that's not a good argument.

[@aquamarine99911]

This isn't an "argument". This isn't Fox News or Rachel Maddow. It's science. Mat Lalonde (who I like, btw) is not an experimental scientist. He has his opinions, but this is his hobby. His job is science safety officer at Harvard, where he also lectures.

[@slickwillie3376]

I agree. Something is off here for sure. Plants are poisonous.

[@terraflow__bryanburdo4547]

The ancient diet has to be that of or species ancestors (H.sapiens), NOT our distant relatives among the apes. When we became carnivorous (H. habilis), we burned the bridges on most plant foods (i.e. lost our caecum, special enzymes, etc.)

[@jussi3378]

You do realise finding these new, better foods come with a cost? Evolutionarily speaking, those who weren't adapted, were less likely to pass on their genes. I'm personally not going to myself or my family members through an eugenics program for the off chance some of our engineered foods would be better for us in the long term

[@nadinejoyce1203]

Good to learn he presented at the new version of "cbj" now known as "people unlimited' out of Arizona...after c ( Charles Brown)died; (b for Bernadine and j for James), calling into question ❓⁉️ their professations of *physical immortality* . I think their meetings may focus more on longevity now. Less on groupie follower power. For the definitive text on physical immortality there is nothing to compare to 'the sidereal testament' by menrise, the pseudonym of Richard Talbot who taught r-e-c-a-r-nation, emphasis on "carn", incarnate, carnivory...at the now defunct *life therapy institute* in 🏜️ desert Hot springs in the 70's.

[@nedisings]

I UNDERSTOOD THAT !

[@yawangle90]

how can this guy be ~63yo, doesn't look anywhere near that age

[@tintintuntun2]

24:58 yes, he cracked the code of ageing.

[@Jean-yn6ef]

💚 really interesting and follows what I've experienced in my own life. Could eat anything in any amount until I had children at 29 through 43 years old. At that point I had to gradually clean up, clear out, and reduce my consumption. I see myself eventually ending up mostly carnivore, as that is what my northern European ancestors had available.

[@terryjackson9395]

Are you going for the lifespan of your European ancestors?

[@terraflow__bryanburdo4547]

@@terryjackson9395 They lived well past 100 years in many cases. Hadza do today.

[@nataleo9093]

fascinating!

[@jhg699]

Beautiful theory. Next time I want to feed my pet fly I'll review the vid again

[@robertb4563]

Ever seen a five-year-old use a smartphone? I guess the young can adapt faster.

[@poorpotato7623]

this deceptively boring lecture is one of the most concrete demonstration that the paleolithic diet is the optimal diet

[@IngenieurAerospatia]

Optimal diet if you are old. And then, only if you are a fruit fly and optimising egg laying ability. Its not a bad model, fruit flies are relatively fast reproducers but you would need to run this across rodents for the next iteration.

[@evaeyez9379]

amazing info he's in his 60!!!????

[@gettingittogether6189]

wait what... oml

[@amodiarosemary1331]

Yes, he looks 20 years younger than his chronological age.

[@marcin1699]

Gotta love some fruit flies experiments extrapolations for human population...but since it's "complex maths based" I'm sold of course, no questions asked (math models are even more valuable than fruit flies extrapolations).

[@aquamarine99911]

"Genetically speaking, people and fruit flies are surprisingly alike, explains biologist Sharmila Bhattacharya of NASA's Ames Research Center. "About 61% of known human disease genes have a recognizable match in the genetic code of fruit flies, and 50% of fly protein sequences have mammalian analogues.""

[@slickwillie3376]

I get the feeling something is missing from the data. Is it just me?

[@RobertPaterson]

Hi Michael - Maybe this is an explanation for why in Southern Europe, Italy etc, people age so quickly and radically - cultures where reproduction starts early?

[@fingersm]

Robert Paterson they age quickly in Southern Italy??
