How much vitamin D in cod liver?

[Berna Blee]

Does anyone know how much vitamin D there is in cod liver? I
can find data for cod liver *oil*, but not for the liver
itself. I have a tin (can) of 120g cod liver in its own oil;
label says it's 99% cod liver and 1% salt. I'd like to know
how much vitamin D is in there, and if I can throw out my
supplement if I eat one of those cans a week.

It would have an excess of vitamin A (retinol).

Thank you! Hmm, that's about 2x the vit. A my Dutch database
says it has (the liver is in there, it just doesn't say
anything about vit. D). Oh, and I see it also has vit. E,
which the 'Eetmeter' also doesn't mention. I've bookmarked
that site, it looks really good.

But now I have another question: how much vit. A is too much?

The optimal of retinol intake seems to be between 500 to 1000
micrograms a day (1500-3000 IU) a day. Take in to account that
you get it from other food sources as well. Greater amount of
retinol is associated with reduced bone mineral density and
fractures in the long term. (Melhus H et al., Excessive
dietary intake of vitamin A is associated with reduced bone
mineral density and increased risk of hip fracture. Ann Intern
Med 1998;129:770-778.) http://www.annals.org/content/vol129/i-

level of retinol intake that is only about twice the current
recommendation for adult females." (Crandall C. Vitamin A

Hm. I've been getting quite a lot then already. But it's
mostly because I've eaten chicken liver a few times; maybe if
I cut that out, I'd be able to eat cod liver once every 2
weeks or so. Looks like I have to eat less chicken liver in
any case. That's a pity, because I really like that stuff. :-(

There is little or no adverse effect from consuming large
amounts of retinol from real food sources. The problem is in
consuming too much overly refined supplements.

The Inuits used to consume vast amounts of these vitamins in
seal oil and they were extremely healthy.

Why would that make a difference? I'd like to think you are
right, and in fact I am trying to get as much of my vitamins
&c. as I can from food instead of supplements, hence my
original question about cod liver; but isn't a molecule of
retinol a molecule of retinol, whatever the source? I do hope
you're right, because as I said I really like chicken liver! I
think I am going to eat the ones I have in the fridge tonight,
even though it's only 6 days ago I ate it last. I'm going to
have to study this a bit more I think, to decide what I'm
going to do long-term; but I don't think one extra dose of
chicken liver is going to hurt me. It's not like it is polar
bear liver! ;-)
