Fish Consumption Linked to Type 2 Diabetes

CB064567A recent study suggests that fish intake may modestly increase the risk of developing type 2 diabetes. 

Harvard researchers examined the dietary habits of over 195,000 study participants over the course of at least 14 years.  Increasing consumption of fish and long-chain omega-3 fatty acids (mostly from fish) was linked to a higher onset of type 2 diabetes—up to 24% higher comparing the lowest with the highest consumers.


This is a preliminary research finding and requires validation by other studies.  The study authors write:

Given the beneficial effects of LCFA [long-chain fatty acids] intake on many cardiovascular disease risk factors, the clinical relevance of this relation and its possible mechanisms require further investigation.

At this point, I believe that the benefits of reasonable omega-3 fatty acid and fish consumption outweight the possible risk of developing type 2 diabetes.

    Oh great! lol

    Can only hope that other aspects of med diet helps out with the type 2 diabetes part!

    That’s encouraging Steve. I’m not gonna reduce fish consumption at all – more if anything.

    Can’t help but wonder about the study. In the Omega Diet Simpolous talks about a study of mega dose Omega 3 – all to good effect. Would have to re-read, but I thought that included diabetes.


  3. Given the amount of data out there with fish consumption as well as pharmaceutical omega 3 supplementation, I’d take this study with a huge grain of salt.
