I take fermented cod liver oil daily (from Green Pastures if you google). I have been taking four caps per day for the past two years. I was introduced to this small company from the Weston Price Foundation. Anyway, i have always been thoroughly happy with the product, and really do believe that i am supporting not only my own health, but a wonderful small company who really cares about our health.
However, i just read a post on their own website by the company manager himself which says "The fclo [fermented cod liver oil] is catabolic, the skate and butter oil are anabolic." Although the whole post itself is very short, if you wanna see the context here is the link: http://www.greenpasture.org/community/?q=node/301
That short statement struck me as odd and i just wondered if anyone on these boards had an opinion (or a study link or two would be great but) as to the truth of it.
I am not sure why cod liver oil would be catabolic. I am guessing you are worried about it preventing muscle growth. I wonder if that is what the offer meant by it. I think on a low-carb type diet, fish oils would add fuel to the fire of burning fat, but I doubt it will break down muscle. If anything I would think its intake would help preserve muscle.
According to some studies fish oil actually is has catabolic-inhibition properties. I would not think there would be a difference in the different fish oils for that effect. http://www.lef.org/protocols/prtcl-029.shtml
I agree with Mike's answer. "Fish Oil would add fuel to the fire of burning fat". It is fish protein that is catabolic not the fish oil. Excess protein will burn fat to get energy and contribute to weight loss. Excess fat intake will contribute to weight gain.
Here's another entry regarding anabolic/catabolic properties of certain oils. A quote from the link above:
"something unusual about the Fermented skate liver oil is that it is anabolic. very key if any other omega 3 rich oils are anabolic."
"to research this topic further look up Revici or revici method"
Edit: hehheh, wrong thread.
I am in the same boat as you as I find this statement to be odd. I did some poking around on the Weston A Price website and found some good articles on fish oils and specifically cod liver oil.
From what I read, part of the debate over CLO is the vitamin A and vitamin D content and the ratio of these two vitamins to each other. There are some who claim that taking CLO regularly will lead to the body storing too much vitamin A: side effects include birth defects, liver problems, and reduced bone mineral density. (source: NIH http://ods.od.nih.gov/factsheets/vitamina/)
I remember reading somewhere else that too much vitamin A prevents the body from synthesizing vitamin D properly. This may be true, but maybe you need something like 25,000 IU a day to get to that point.
I have no idea if this is what the company manager was getting at or not. Again, I can't think of any reason why CLO would be catabolic. I do not plan to stop taking it daily.
