How Cod Saved the Vikings

The Vikings suffered many hardships living in the north of Europe: long, cold winters and importantly a lack of sunlight. Luckily, they had cod.
Check out Vitamania:
When making a video about vitamins I thought the story would mainly be about supplement pills, whether we should or shouldn't take them and how they're made. But what I found out is vitamins have a remarkable story that affects many more aspects of our lives. For example the Vikings needed a source of vitamin D to last the dark winter months and for their children to develop strong, healthy bones, avoiding rickets.

Do one thing tell the person on Mars to send his time and blast Mars at the same time (Assuming it takes 20 mins for light to travel from earth to mars and instantaneous for light to travel from mars to earth ) Earth send message at 12 :10 Mars recieves at 12 :30 but the person thinks it is at 12 :20 and send a message that the time is 12:20 and instantaneously blast Mars Now if earth saw mars in real time earth will see Mars blast at 12 :30 and earth will also receive a message that it is 12: 20 and hence proved that the previous assumption was correct that it takes 20mins for the light to go to mars and instantaneously comes back to earth

Nice one, but didn't you wonder why the vikings on their long trips didn't get scurvy? 🤔 It's because all they ate during their trips was fish and meat. They were on carnivore diets. You don't need lemons or vitamin C supplements when you eat a carnivore diet. Something to think about. 🤔

Another amazing video. I particularly liked the part around 5:00 where you explained how the practice of drinking the liver oil might have caught on. Too often in teaching complicated ideas we get bogged down in personifying the involved parties. This was a great description about a natural emergence and development of a concept.

There's some people who think your bone marrow wants to produce blood cells as if you're going to have a bunch of small injuries (as a hunter-gatherer would), and by bloodletting or blood donation to simulate that, you can marginally improve your health (assuming your diet has enough iron and protein that you won't miss the extra blood).

A reply to your argument that "the scientific method is the greatest technology that humans have ever developed."- I would counter that the ability to store and use information is more critical to human cultural and technological development, and is an underlying necessity for the scientific method.

You have to wonder if the Vikings actually figured out the secret of needed vitamins or was it just a fact that they needed to eat and the fish was there? As far as cod liver oil again I really think that it was recognized as providing energy perhaps as a skin treatment and so on. I doubt the average Viking had any concept of the actual relationship of vitamins and health and where these came from.

Hopefully you see this comment. My blood test indicated low vitamin D. I watched your show Vitamania. When researching ways to get more vitamin D i used cod liver oil. However, you didn't mention mushrooms. Furthermore, there is the interesting suggestion that if you expose the gills to the sun prior to you eating them you can get vitamin D on the order of thousands of milligrams above your RDA. I hope you explore that more in an future episode. Thanks

Great video! Being a Norwegian I've noticed the use of cod oil (tran) has diminished over the past 20 years. I'm guessing it has been replaced by (other) supplements and D-vitamine fortified food. But before that tran commercials where usual. I remember my grandparents emphasise the importance of tran as part of the daily diet. That would be a (circumstantial) evidence for scientific knowledge through evolution. 🙂 Oh, and BTW: science is not a technology; it's a kind of knowledge. 😉

i remember a story my friends up in north of Sweden told me about their parents and going way back, they used to have a barrel of liquid and at the surface it was mold. Once a week they were forced to drink that liquid, i can't even imagine that taste lol. their ancestors knew way before the invention of penicillin that drinking that liquid with mold kept them healthy. That is pretty amazing.

As a Norwegian l thank this channel for only discussing cod, and not mentioning the shame of our sweetened pickled herrings. Oh well thanks to this video at least now l know why they exist and it's because some severe illnesses are actually worse than eating sugary pickled herrings. Wow.

Great information, I'd just add about the British, one must consider the Irish contingency of Vikings were ousted by the Jews, and the Dutch to a degree, and moved to Wirral in England. They then crossed the Mersey River to inhabit much of South West Lancashire. The county is the Red Rose County, and the 2nd city of the empire, Liverpool, is also in South West Lancashire. So there's a direct connection, plus Scandinavian companies to this day pay no taxes here, England, if they are based here, they pay it to their home country. England was ruled by Danish King's for a spell, read Hamlet by Shakespeare. 😁

If you want to understand the value of conservatism, it's at the heart of the failure of the Greenland colony. Culture brings customs that carry inherited knowledge of what works. Much of it isn't understood. Much of it is wrong. But the cultures that have lasted millennia have important insights to contribute. Progressivism is important, of course, but it must be tempered with humility. Vegetarianism in Viking culture would have been ethical and possibly deadly.

More like the cod liver oil drinkers survived and procreated, the non drinkers either died of osteomalacia or gave birth to children with rickets. Just emulate Darwin, no need of fancy theories here.

In Norway the most common cod liver oil product is Tran. and there's a saying that you should drink a little bit of tran every day in the months that have and R in them. And it its because it's the months with the least sunlight.

The fiefdom of Normandy was given to the vikings in the treaty of Saint-Clair-sur-Epte to get them to stop raiding West Francia (France). The vikings/normans instead conquered England. So the British fleet that "came to dominate the sees" were in some way a little bit viking.

Regarding wisdom in tradition. You're points made me think of psychedelic mushrooms and other hallucinogens. There are benefits to them in a number of areas, but science have been slow to research them. Many of the insights about them from users and researchers aren't taken seriously to fund more scientific research. I love science, but it feels like the institutions for research are regressive and not so open mind sometimes.

Cod Liver oil isn't a health invention. It was just one more way to preserve a food source. Everything was preserved one way or another. When this oil was first invented there was no medical meaning behind it. And then, pretty much all oils or preserved liquids were said to be miraculous and good for you in a way or another. This is a basic behavior in any self sufficient society.
