B12 Deficiency Video

[MoKayD]

This video does not address the need for B12 injections, it just recommends oral supplementation but I still thought it was interesting nutritionfacts.org/video/fr...

Very nice video! I liked all the papers he referenced - a few I had not seen before (like the functional deficiency one and the unsuable...hands..something, going to look them up now LOL. He mentions PA but does not really explain it unfortunately. Nice find, thanks

BTW I added your video to the Various resources page so you may have gotten a tag notice.

I thought the parts about gorillas eating their feces to get B12 was really something 😂😂

[MoKayD in reply to jade_s]

The gorilla reference was pretty funny. Dr. Greigor is kind of a goof ball but I trust his quality research.

I like Dr. Greger and his daily dozen app was extremely helpful for me in improving my diet. I watch many of his videos and I like his book ("How Not To Die"). He also has very useful and (mostly) accurate supplement recommendations. But I will say, he has some flaws to be aware of. His position in several areas is not evidence based. For example, he often argues for low fat and removing oils from the diet when evidence-based nutrition shows clear benefits to replacing saturated fats with poly and monounsaturated fats like olive oil and rapeseed/canola oil. He overinflates intervential studies that claim to have reversed heart disease where the intervention included many lifestyle changes other than diet, which he nevertheless attributes to a low-fat wholefood vegan diet.

He never distorts a paper (to my knowledge) but he does cherry-pick papers - you will never see a video from him in which he admits that evidence based nutrition shows that some types of fatty fish eaten twice a week are generally beneficial, that some types of dairy, in certain amounts are not necessarily harmful and that small amounts of other animal foods will not be detrimental to health, for example even unprocessed red meat under 400g (2 servings) a week. If you listen only to Dr.Greger all animal foods, in any amounts, are poison.

To get a more unbiased view, I prefer to listen to folks like Simon Hill, Gil Carvalho of Nutrition Made Simple, Alan Flanagan of Sigma Nutrition, Walter Willett, Christopher Gardner and others who take a 100% evidence based approach. I am an ethical vegan but I don't want my knowledge of the nutrition research to be distorted by this - if the evidence shows that eating some particular amounts or types of animal foods to be healthy (or at least not harmful), then that's what it shows, I think there's no excuse for distorting the science to support a foregone conclusion.

[MoKayD in reply to Technoid]

I'm a dairy loving carnivore so I just ignore his vegan proselytizing. You're right about his cherry picking. In spite of that, I feel he does a lot of the research study heavy lifting for me. Often one of his articles will send me off to dive deeper into the subject

[Technoid in reply to MoKayD]

Indeed, his videos are an avalanche of research 😁

Thanks for the list of people to follow Technoid . I'm on a nutritional health pathway now and this is a great start to have recommended good sources of advice. As you say, it's v time consuming trying to work out who cherry picks info and who uses good quality info. 👍

Not seen that before.So noone knows an oral dose needed without PA or an absorption problem.

Gp told me to take 2x 50mg b12 tablets a day to reduce Injections not stop them.

This is common practice I wonder on what evidence?

Then it's a 1000mcg a day and so on .

Definitely the message of supplements before you get ill persuasive and nowhere advised unless you follow a vegan diet ??

Just looked at my multi vits.

Some for over 50s

Some adults any age

B12 2.5mg

Over 50 3mg !

Different makes have no more.

However my husbands b12 serum was 180. ( 200-900) first test.

No symptoms but pushed to check it out by me.!!

He takes 2.5mcg oral b12 daily .

His serum b12 rose to 360 ( 200-900)

He doesn't take any other supplements but continues to take these.

Obviously absorbs and a boost.

So without an absorbtion problem that video makes sense 🤔

Yes I agree.
