Medical Forum / General / Nutrition / July 2005How much vitamin D in cod liver?
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. Berna  Signature( )_( ) Berna M.

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? Berna Signature( )_( ) Berna M.

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/issue10/images/large/3TT6.jpeg "Adverse effects may occur at a level of retinol intake that is only about twice the current recommendation for adult females." (Crandall C. Vitamin A intake and osteoporosis: a clinical review. J Womens Health (Larchmt). 2004 Oct;13(8):939-53.)

J Womens Health (Larchmt). 2004 > Oct;13(8):939-53.) 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. :-( Berna Signature( )_( ) Berna M.

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! ;-) Berna Signature( )_( ) Berna M. Bleeker-Slikker / . . \ berna.bleeker@gmail.com \ \@/ / http://www.volksliedjes.nl |
