Guest guest Posted December 14, 2003 Report Share Posted December 14, 2003 The question is: Is there something magic about eating fish flesh (other than the touted omega 3's which I can get from fish oil)? BTW, I've read where some of those small pens are actually contiguous with ocean waters, not just contained lakes, whatever. Probably helps to pollute the ocean, maybe more than raising cattle. Regards. ----- Original Message ----- From: Gifford Sent: Sunday, December 14, 2003 9:41 AM Subject: [ ] Mercury and Tuna > If there is some magic to eating fish> flesh maybe smaller, farmed fish would> be safer.If you're worried about the sanitary side of eating fish, then you shouldavoid farmed fish. Farmed salmon are raised in small pens where theyessentially eat/ breathe/ live in their own faeces. Lice infestations arealso extreme in farmed fishI personally stick to wild salmon (Pacific) from smaller fish. When I havethe time, which is not very often now, I try to acquire fresh wild trout,though the time spent on that has little to do with the food...Cheers,________________________ Quote Link to comment Share on other sites More sharing options...
Guest guest Posted December 14, 2003 Report Share Posted December 14, 2003 Dunno for sure if there's more to fish than oil, but I'd suspect so. Some studies have suggested as much: Cancer Epidemiol Biomarkers Prev. 2003 Jan;12(1):64-7. Links A prospective study of intake of fish and marine fatty acids and prostate cancer. Augustsson K, Michaud DS, Rimm EB, Leitzmann MF, Stampfer MJ, Willett WC, Giovannucci E. Department of Nutrition, Harvard School of Public Health, Harvard Medical School, Boston, Massachusetts, USA. katarina.augustsson@... Experimental studies suggest that marine fatty acids have an antitumor effect on prostate tumor cells. The aim of this study was to investigate whether high consumption of fish and marine fatty acids reduces the risk of prostate cancer in humans. We followed 47882 men participating in the Health Professionals Follow-up Study. Dietary intake was assessed in 1986, 1990, and 1994, using a validated food frequency questionnaire. During 12 years of follow-up, 2482 cases of prostate cancer were diagnosed, of which 617 were diagnosed as advanced prostate cancer including 278 metastatic prostate cancers. Eating fish more than three times per week was associated with a reduced risk of prostate cancer, and the strongest association was for metastatic cancer (multivariate relative risk, 0.56; 95% confidence interval, 0.37-0.86, compared with infrequent consumption, i.e., less than twice per month). Intake of marine fatty acids from food showed a similar but weaker association. Each additional daily intake of 0.5 g of marine fatty acid from food was associated with a 24% decreased risk of metastatic cancer. We found that men with high consumption of fish had a lower risk of prostate cancer, especially for metastatic cancer. Marine fatty acids may account for part of the effect, but other factors in fish may also play a role.

Guest guest Posted December 14, 2003 Report Share Posted December 14, 2003 there's so much we don't know about the health giving effects of eating the whole enchilada. Try to get your nutrients from foods rather than supplements seems to be the moral of the story. on 12/14/2003 2:53 PM, Dowling at dowlic@... wrote: > Dunno for sure if there's more to fish than oil, but I'd suspect so.

Guest guest Posted December 15, 2003 Report Share Posted December 15, 2003 Hi : The fish may be the reason the japanese have a very low incidence of prostate cancer despite consuming a fair amount of alpha-linolenic acid, which seems to be associated with increased prostate cancer risk. (There are very nearly as many new cases of, and deaths from, prostate cancer in men as there are of breast cancer in women. So this is not a minor detail).

Guest guest Posted December 15, 2003 Report Share Posted December 15, 2003 Most, (likely all), "Atlantic salmon" sold in stores in North America is farmed salmon. The fish are raised in sea pens in the North Atlantic European coastal waters (Norway and south). I won't buy it because of the amount of pesticides fed to them to control parasites, which are a problem because so many fish are raised in crowded conditions. : -( Bruce -who ties a mean deer hair nymph- : -) ----- Original Message ----- From: jwwright Sent: Sunday, December 14, 2003 9:04 AM Subject: Re: [ ] Mercury and Tuna The question is: Is there something magic about eating fish flesh (other than the touted omega 3's which I can get from fish oil)?

Guest guest Posted December 16, 2003 Report Share Posted December 16, 2003 Hi Jw: Maybe. And if so then my bet is that the 'rda' for mercury will have been more than taken care of by leaching from the fillings in our teeth.
