Unofficial thoughts on medicine and medical school

Hi All!

This is a quick note, so, poorly written, but I’ve been looking up the safety of fish,and I think the take home message seems to be that lots of fish are unsafe — unfortunately.Marion Nestle’s book, What To Eat, talks about this in detail.  She reports that a studycame out in Science (2004) which looked at the PCB levels of 700 samples of salmon from all over the world.  

Salmon is typically known as one of the safest fish out there, and one of the mostnutritious.  Unfortunately, this report found that these salmon all were contaminatedwith unsafe levels of PCBs.  Only salmon from Chile and Washington State were deemedacceptable.  Fish from everywhere else?  The study found those other salmon simply had unacceptable levels of PCBs.   

Moral of the story?  It seems like this would be an argument whyone would want to use fish oil supplements — from a good brand which has taken outall the dioxins, PCBs and methylmercury.   Only five brands — omegabrite,nordic naturals, olay, vitamin shoppe and coromega have allowed themselves to be independentlytested for dioxins, PCBs and methylmercury (source: www.consumerlabs.com).These are just drafts of thoughts, so more on this later — but I wanted to just let you all about this sooner, as opposed to later.

Best,

Jeff
