What did you learn today? Share it with us!

We learn something new every day. This is a community dedicated to informing each other and helping to spread knowledge.

The rules for posting and commenting, besides the rules defined here for lemmy.world, are as follows:

Rules (interactive)


Rule 1- All posts must begin with TIL. Linking to a source of info is optional, but highly recommended as it helps to spark discussion.

** Posts must be about an actual fact that you have learned, but it doesn't matter if you learned it today. See Rule 6 for all exceptions.**



Rule 2- Your post subject cannot be illegal or NSFW material.

Your post subject cannot be illegal or NSFW material. You will be warned first, banned second.



Rule 3- Do not seek mental, medical and professional help here.

Do not seek mental, medical and professional help here. Breaking this rule will not get you or your post removed, but it will put you at risk, and possibly in danger.



Rule 4- No self promotion or upvote-farming of any kind.

That's it.



Rule 5- No baiting or sealioning or promoting an agenda.

Posts and comments which, instead of being of an innocuous nature, are specifically intended (based on reports and in the opinion of our crack moderation team) to bait users into ideological wars on charged political topics will be removed and the authors warned - or banned - depending on severity.



Rule 6- Regarding non-TIL posts.

Provided it is about the community itself, you may post non-TIL posts using the [META] tag on your post title.



Rule 7- You can't harass or disturb other members.

If you vocally harass or discriminate against any individual member, you will be removed.

Likewise, if you are a member, sympathiser or a resemblant of a movement that is known to largely hate, mock, discriminate against, and/or want to take lives of a group of people, and you were provably vocal about your hate, then you will be banned on sight.

For further explanation, clarification and feedback about this rule, you may follow this link.



Rule 8- All comments should try to stay relevant to their parent content.



Rule 9- Reposts from other platforms are not allowed.

Let everyone have their own content.

My doctor told me that vitamin B12 deficiency is common these days, because we get B12 from bacteria that live in dirt and with how cleanly our food is now, you just don't get the occasional dirt in your diet anymore (and the animals you might consume don't really get that either).

So, maybe¹ eating dirt might actually be healthy.


¹) Okay, no. Get B12 supplements. They're almost as cheap as dirt and don't give you illnesses.

Nutritional yeast is also cheap and supposed to be a good supplement of b12 too

[–] NottaLottaOcelot@lemmy.ca 7 points 16 hours ago (2 children)

I think B12 is found in most animal products. Interestingly, rabbits are one of few strict herbivores, and have to eat their own feces because it contains some B12 produced by their intestinal tract, as they have too few other dietary sources

Most carnivore humans are b12 deficient. And also at risk for cardiovascular disease.

Everyone should just take b12 and d supplements.

Most carnivore humans are b12 deficient.

How are carnivores at high risk for B12 deficiency?

https://ods.od.nih.gov/factsheets/VitaminB12-HealthProfessional/

Perhaps you mean the standard diet, which is omnivore and 70% plant based already, in which case yes - lots of people are under eating essential animal proteins and at risk for deficiencies.

And also at risk for cardiovascular disease.

I'd love to see a non epidemiological source for this. Especially in zero carb carnivores, heck even ketogenic people, not the 70% plant based omnivore that is carb loading and eating processed food all day. We know from early pre westernizationed health surveys of carnivore populations they didn't have CVD.

From my reading CVD is driven by inflammation and hyperinsulinemia. Zero carb carnivore fixes the insulin so the cardio vascular system works properly and can repair properly, and is very low inflammation.

The good news is that people like this won't spread disinformation for long...because they'll die very young

[–] jet@hackertalks.com 1 points 3 hours ago* (last edited 3 hours ago)

it's disinformation to ask for the sources of your statements? My reading of the literature indicates a metabolically healthy individual eating meat and not inflammatory compounds like seed oils, and not suffering from hyperinsulinemia (excessive dietary carbohydrates) does not have a meaningful CVD risk. I'm happy to share my sources.

Wishing you all the best health and long and happy life.

How efficient! Why didn't we think of this before? We can make vitamin B12 inside our bodies, but instead of just retaining it, we'll make it so that it has to be shit out first then and re-ingested to be absorbed. Perfect!

[–] WraithGear@lemmy.world 15 points 19 hours ago* (last edited 19 hours ago) (1 children)

My knock off 5 hour energy gives me 20,000% of my daily dose of B12!

[–] NIB@lemmy.world 15 points 18 hours ago (2 children)

B12 isnt easily absorbed by the body, thats why supplements and food have wild daily portions, so even if you pee most of it, you still absorb some.

[–] zarkanian@sh.itjust.works 1 points 3 hours ago

You probably have enough B12 stored in your body to last for years.

Estimates suggest that a healthy adult's body holds between 2 and 5 milligrams of vitamin B12, with approximately 50% of this total amount residing within the liver. This substantial reserve is why it can take anywhere from three to five years for a deficiency to manifest after an individual stops consuming B12-rich foods.

Large numbers look impressive, though, and since it's water-soluble, you're just going to pee out the excess.

Methocobalomin is.
