Dha, uv light, magnetism and grounding are the key elements to a healthy life but with all the emfs, concrete , big food , big pharma are making sure we dont realize this or else they wld go out of business
Thanks, Dr Kruse! 😁
Thanks, jack
Thanks, Carlos!
Brilliant of you to get the GREAT Michael Crawford! 👏🏽❤
'Brain awareness week!! Yes, what a concept! Thank you both, for such focus on DHA and marine resources.
Oh my! Most impressed as this brilliant man wraps up with his passionate inspirations for “regenerative” marine foods farming - bring back our rich marine resources, and communities so sustained.
Amazing and highly informative conversation, thank you both!
Very interesting discussion
Great work man!
Yes Max, do one again with Cameron! And discuss this.
Thanks so much for this hugely important and interesting discussion. I have long been a big fan of Elaine Morgan's book The Aquatic Ape and her theory which has been supported by more recent findings eg Vernix on seals and human newborns. I wonder if you could do an entire session on this fascinating topic?
No seafood for 54 years and having excellent health. I do take an algae DHA/EPA spplement, much better than dead fish.
first, the algae DHA/EPA supplement is a result of science, which in turn is based on a culture of large brains...
second, show me your blood bio markers first before claiming excellent health
third, if you are so proud of having survived malnutrition, why are you then taking a supplement?
fourth, alzheimers and dementia due to lack of DHA shows up as an end stage, you might have collected a lot of damage already....
No, those oils are highly unstable and prone to oxidation. It has been shown that many, if not most, of those supplements contain rancid oils not suitable for human consumption. It is much better to eat fresh or freshly frozen animal foods.
Watching from Liverpool, great stuff!
Indigenous peoples in coastal AK, are now focusing more on harvesting and utilizing kelp as well as oysters and other shellfish on a commercial scale. And, to supply to more inland peoples. Just like the ancestral trade routes must have done, but western (pinker people') had discouraged (to say the least).?!?
I’ve been trying to find how heat affects DHA in seafood. Unfortunately, some of the best source I have for DHA is canned sardines. Do you know if it’s degraded or altered by heat?
Prof Crawford discussed this with Cameron Borg on the Ricci Flow Nutrition podcast. Crawford suggests not significantly. Worth watching that interview as well as ones with Food Lies/Brian Sanders, Decentralized Radio.
Dr. Rhonda Patrick has talked about studies that show high omega 3 intake of the Japanese from seafood may be responsible for their longevity despite their heavy smoking (among men). I've incorporated canned chub mackerel or sardines in water one can everyday. They are too small to be farmed and swim too deep to worry about mercury poisoning.
Sardines in Olive oil for me. 🏋🏻🏋♂️🦊
Olive oil much better in terms of preservation than water.
@@omrit2 Not all oil labeled "Olive" is "Olive". And Canola is highly toxic. Best not to risk it.
@@bethannea4842 oxidised canola. If you drain the oil first, the benefits by far far far far outweigh the effect of canola... And there are sardines canned in bio EVOO
And, NIR to be increased by outdoor light exposure, for maintaining brain!!?
Feeding brains and marrow (and other fat) to very young children just as they are weaning, must enable a bit more movement inland?
Algae is where the fish get their DHA. A vegetarian alternative is DHA / EPA supplements from algae. Also most folks can convert the omega fats from ground flaxseed into DHA.
This conversation is extremely small & insufficient to meet massive requirements of optimal brain growth. Need preformed sources, preferably marine food web
the conversion is very slow, and inefficient. Only2..5% of ALA get converted... you would have to eat sth like 3 kg flax seed per day... Do You?
@@monnoo8221 Are you familiar with the research and my genetics? Can you offer a Pubmed link that contradicts the WHO and MayoClinic on AA conversion rates? I do take preformed DHA/EPA from algae sources, as suggested in my comment, along with flaxseeds, just in case. Thanks for your concern.
@@ddexteraI’ll take this chaps wisdom, experience and knowledge over any (particularly recent) pubmed study and certainly anything the WHO or any other government/state body says. Nowadays they are all utterly compromised by big pharma funding and as such cannot be trusted. There is a hard push towards veganism, algae fits that narrative, humans are meant to eat animal source for the majority of their nutrients. Don’t buy into the mainstream lies, it will be to your detriment.
Is canned seafood (sardines, mackerel, wild salmon) good?
Yep🏋♂️🏋🏻🦊
Do what you can with what you have
if good quality, yes. Sardines are a super food
@@maxgulhanemd Nice pun! And thanks answering.
c0v1d is what happens when we the humans are deficient in DHA
Can a vegetarian get adequate Omegas from ALGAE OR NOT?
Would you please provide me an alternative option… I really hate killing anything!!!
Algea are also alive.
Hating the idea of killing anything is just a thought that you have. Most of our thoughts are not particularly good or useful. Everything dies and everything eats something else. It's the warp and weft of life.
Not sufficient. See Crawford pods with Cameron Borg (ricci flow nutrition) & Decentralized radio to learn more about
Neanderthal expanding in latitude northward became light-limited, and had to wait for physiology to adjust, gradually adapting? Were their populations more numerous along coasts? Eating brains could have increased DHA, as they moved more away from the marine environment? Hunting youngest megafauna, could have increased the DHA content in the diet, yielding better survival even though they were more inland?
I’m curious about this too
Eating only leaner meat of springtime adult megafauna, would pressure toward illness, if the people did not balance this out with an equal amount of fat? So, they needed to eat the young rather than the adults in the spring, but the adult megafauna in the Fall would have been fat enough, so young animals would not have been as necessary to eat then? So this is largely maybe sub optimal DHA, but enough to sustain health enough to live more inland? Light exposure must have been critical to maximize to live more northerly.
Does retinol increase in eyes of people living more northerly?
the last surviving Neandertals, also as it seems, most culturally evolved, lived on the coast of gibraltar
Oysters as antidote for beer, must help survival in a bar!?
If the Bristol mothers had eaten more brain of inland mammals, could they have compensated a bit for for less marine diet?
If they ate young mammals, including brain and marrow, and eyeballs, could these mothers gain enough DHA even though they were eating less marine diet?
Dr. Jack Kruse, kicking his ass . ❤ 😢
haven't started yet....but have listened to Me Crawford before.....Where he talks about a direct line correlation between DHA consumption and IQ. I'm on a very tight budget BUT the day i get paid (once a month) I go get some sashimi and bacon wrapped scallops!!!!!
We FILIPINOS EAT A LOT OF SEAWEEDS and OYSTERS!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! FULL OF OMEGA 3'S / DHA/EPA
summary : we almost evolved into whales :))
thank you very much for this fascinating interview.
instead of spending billions in order to go to Mars, Elon should spend just 500 mio to develop large scale free floating and sustainable marine food production devices.
Agreed. there are much more pressing human problems on this planet and marine agriculture is one
centenarians don't eat marine foods. only in Okinawa and only a bit
The problem with seafood: loaded with mercury & other pollutants 👀
When you eat healrhy and keep the nervous system calm. Those thing s don’t matter.
We didn’t go in depth in this podcast but the solution exists in the fish- selenium & selenoproteins. See Crawford podcast with Cameron Borg Ricci Flow nutrition & my 2nd podcast with Lily Nichols to learn more. Advantages >>> risks seafoods
And who do we thank for that .Our caring government
simple rule. the bigger the fish, the more polluted. Sardines and mackerels are small. Atlantic sardines are effectively free of pollutants
Had pink ling last night, beautiful.❤
omg please read up on this more. Lesson 101: fish is a source of omega-3s, fish themselves do not produce them. Rather, they are obtained from the algae (microalgae in particular) and plankton consumed in their diets. We can produce these now, without fish! So yeah you don't need to kill any animal to get it. Goog health to you.
Poor Plankton
Some research people need spokespersons who can be understood.
I'm still not convinced. Lamb is just as good of a source.
But would you have to eat the wall too?
I meant 'wool'.
@@raykinney9907 no...but you probably need the brain. I take back what I said, because I've been in a slump...an emotionless state...in a haze...for like 3 days. I had a tin of sardines and the veil was lifted, lol. For the EPA/DHA, you'd need the brain and I haven't been able to source that in awhile.
@@Afrobomination LOOOL ... from that you can derive a direct recommendation for your own nutrition...
The biogenics field (Ray Peat community) is saying Omega 3's in any appreciable amount is actually harmful.
He's a clown. Probably bought and paid for by some US health group with globalist banker money.
Michael Crawford is an actual genius tho…
I think Crawford's work demonstrably shows the problems with demonising PUFAs in all forms. Clearly omega-3 in form of seafood is essential
However, he was a huge promoter of oysters, cod, sardines, calamari and shellfish.He was against the guzzling of fish oil. As we have enzymes which take the hydrogens off a saturated fatty acid, the body is able to produce the unsaturated DHA as needed. It was the lack of B-vitamins and other minerals which impeded these enzymes.
As Crawford states, the value of sea food is much much more than DHA. I fell for the scaremongering about mercury and pcbs and completely removed seafood from my diet. I did this after testing high in mercury and other heavy metals. My health suffered big time. After finding Peat in 2012, I introduced shellfish, cod and crab & lobster into my diet. My latest test for mercury, lead, cadmium and arsenic were surprisingly low.
Michael Crawford's work though is next level - truly impressive. I could eat seafood every day easily but I can't eat red meat, chicken or pork every day as I quickly tire eating land animals. I find this strange as my ancestors come from high mountainous area in Europe. Far, far from the sea. Cod was eaten only on festive days like Christmas and Easter. Perhaps, these populations had very efficient desaturating enzymes or their native diet was rich in cofactors and minerals to support synthesis of endogenous DHA. They ate pork and lamb and their only fats were lard, occasional olive oil and dairy fat from sheep cheese. Their pig's were fed good food to produce the best quality and flavoursome meat. They were very particular on which food to feed and not to feed.
He seems healthy ? 😢.
He's 94 yrs old. In case you don't know.
@@inviteweddingid6011 and his brain sharp as a knife !!!!!
for sure, some other parameters he did not optimise...
Exceptionally lucid and stable (Very Healthy!). Lovely brain in action, amazing esp at his ‘era’.
❤❤❤
WRONG !
no, bro, its not wrong, its dead simple and his statements about DHA and the brain 100% correct.
btw, to what specifically d you refer? are you addict to some sort of elimination diet?
@@monnoo8221 I agree with DHA , Omeg 3s and the brain . Eyes mind heart and soul wide open. NO FEAR! Decentralization, Ai will soon take the guess work out of it and all gurus and snake oil salesmen will soon be gone. Don't die,we are coming. See you in 2500 . !
