POP Pollutants in fish?

Always read from the original sources, not from the site that tries to sell you supplements through fear (avoid the middle-man):

http://care.diabetesjournals.org/cgi/co ... t/30/3/622*Nowhere is fish mentioned

http://www.newscientist.com/article/mg1 ... betes.html*Nowhere is fish mentioned

http://news.bbc.co.uk/2/hi/health/6544709.stm *This one is funny, as the headline uses fish as the 'shock factor,' but nowhere is the claim justified in the rest of the article.

But I will add that it has been established elsewhere that fish, and many other foods, contain POPs. Still waiting on definitive prove on everything else.

Also:

No causal link

But the work does not confirm a causal link - it is possible that that having insulin resistance could reduce people's ability to clear POPs from their system, thus explaining the association.

Lead author Professor Duk-Hee Lee said the evidence needed to be replicated and developed in other studies, and called for molecular studies to explain the link between pesticides and insulin resistance.


Matt Hunt, Head of Science Information at Diabetes UK, said: "Insulin resistance is often observed as an early warning sign for developing diabetes and therefore possible contributors to this state are always of interest."

However, he said the current research was very complex and still speculative and did not provide a mechanism by the which the POPs could cause insulin resistance.

He said: "At the moment we would not conclude that the rise of obesity can be attributed to pesticide use, and should still be put down to increasingly unhealthy diets and lack of exercise."

Most of us here do not eat large amounts of fish, nor are we obese, so we have little to worry. However, soon pollutants in fish may become out of hand, and we will eventually have to find replacements, such as eggs and meats. But it has not come to that point yet.

Know your fish: do not buy the most polluted species, and avoid commerically farmed fish (with a few exceptions). This will cause one to avoid a majority of the chemicals and pollutants, and hopefully the body is healthy enough to take care of the rest, for now...

Thank you!! Good reply!!

Oh Tampa Bay, I used to live in St. Petersburg. Neat!!

Darkgalaxy,

I actually wouldn't worry excessively because of POP, dioxins or other toxins in fish, just because a diet composed mainly of raw vegetable material do its homework detoxifying those substances.

See:

http://www.jstage.jst.go.jp/article/bpb ... e/-char/en

Where they conclude: "These results suggest that several vegetable constituents might play a role in protection against dioxin toxicity."

Regarding dioxins,

From http://en.wikipedia.org/wiki/Dioxins_an ... rough_diet,

The major sources of human exposure (96%) are

Animal fats found in meats
Full fat dairy products
Fatty fish (herring, mackerel, salmon, sardines, trout, tuna)
