C - It could be any # of labs - there are hundreds of them, e.g.:

- Eurofins
- Matis
- Exova
- Intertek

The first step in fish oil refining (short path distillation) removes most of the contaminants like mercury. Not all DS makers are created equal. Clearly some are more responsible than others.

Here's a lab posted voluntarily to Ifos for the OmegaVia 500 EPA rTG (which I've described in an earlier post as being a voluntary organization for the more responsible DS makers to submit their labs for a given batch of O-3). I myself would not be worried about 10mg of DHA in a 500 mg pill even if I had CVD. Also, the color is removed in the processing of the fishoils to make it clear as I stated in an earlier post. It's called the Gardner score - for V the Gardner score is 0 after processing (show the purity to the naked eye). Natural fish oils vary depending on what the fish have been eating - their scoring could range from 8-14. If the fish have been eating more krill than the oil will be more red. If they have been eating more copapods or worms then the oil will usually be more yellow.



I think its important to remember that Dr. Preston Mason's video - while I thought it was very good is still a marketing tool to promote V created by a biomedical research firm for AMRN - they crank out studies on demand. That doesn't diminish it's message, but I thought when I watched the video originally posted the week after AHA by Zu as I recall, that it was a little bit wonky regarding the processing slides and that fishoil is used to feed animals (like for aquaculture).

We all are animals. The FDA approval processes to certify plants are practically the same, just parallel, regarding approvals for human or pet food plants for example. The reason? Because some Americans eat pet food.

Lipid oxidation is a problem for all oils - Americans consume a lot more soy and corn oil than fish oils. We should start with reducing our edible oils consumption.



Global oils consumption by type:



I don't know if anyone else on the board has read Dr. Cate Shanahan's book "Deep Nutrition" (first edition was 2008 and then she updated it last year) - I just started reading it. She's a PHd in Biochemistry out of Cornell and a MD from Rutgers. Plus, she spent 10 years in Hawaii studying ethnobotany. Pretty fascinating especially her focus on epigenetics and it more than helps her cover for the lack of nutrition training in a typical MD curriculum as she said. Also, in the hierarchy that is modern medicine nutrition is lower on the hierarchical totem pole compared to other subject areas. Preventative medicine is often seen as a "womans" domain, ...or so I've heard.

Strange since maybe if there had been enough other doctors grounded in the science they could have more effectively challenged Dr. Ancel Keys back in the 50's before we got into this CVD mess. US soy consumption (and I believe edible oils are about 30%? of our 1800-3000 calorie American diet...)



I may read this one next:



Typical medical school curriculum (the 4 years before residency) - I don't see too much human nutrition:











I wonder if Dr. Preston Mason is still planning on presenting in Portland at the end of Feb. at the Clinical Lipid Update I may drive down to see if can listen in.
