Could Fish Oil Fatty Acids Raise a Woman's Risk for Diabetes? Is it a doubt or fact?
The finding no doubt is sure to complicate traditional dietary thinking, given the fact that highly touted health benefits often associated with this group of essential nutrients, which includes the omega-3 polyunsaturated acids typically found in fish.
The study authors Fagherazzi and Dow were scheduled to present their research this week at a meeting of the European Association for the Study of Diabetes in Munich, Germany. The findings should be viewed as preliminary until published in a peer-reviewed journal.

-“- Women who consume high amounts of meat, fish, eggs and other common foods rich in several different types of fatty acids may end up facing a greater risk for type 2 dinoabetes, a large and long-term French study suggests.”
The study authors, Guy Fagherazzi and Courtney Dow, both epidemiologists with the Center for Research in Epidemiology and Population Health at INSERM in Villejuif, France say ."The principal sources of the harmful fatty acids in our study were meat and fish/seafood," said "However, we would not go so far as to say that fish is no longer a healthy and safe option," the study authors said. "Other studies are needed, and it was only in the group with the highest consumption of these fatty acids that we observed an association." Dietary questionnaires revealed consumption habits regarding several types of fatty acids, including:
•arachidonic acid (AA), an omega-6 fatty acid found in meat, fish, seafood, and eggs;
•docosapentaenoic acid (DPA), an omega-3 fatty acid found in meat, fish and seafood;
•and alpha-linolenic acid (ALA), also an omega-3 fatty acid found inflaxseed, canola oil, walnuts, and certain types of eggs.
Overweight women (with a body mass index over 25) in the highest consumption group saw their diabetes risk go up by 19 percent, compared with those in the lowest consumption group. By contrast, normal-weight women (body mass index under 25) saw their relative risk go up 38 percent, the findings showed. DPA, for example, was linked with a 45 percent jump among normal-weight women and a 54 percent jump for overweight women in the highest consumption group, compared to those in the lowest. In the highest consumption group, AA was associated with a 50 percent increased risk for normal-weight women and a 74 percent increased risk for the overweight, compared with the lowest consumers.
By contrast, ALA was not linked to any increase in diabetes risk among normal-weight women. And among overweight women, ALA was linked to a relative increase of just 17 percent among the highest consumption group.
The researchers noted that meat was the largest source of both DPA and AA, making up 31 percent and 43 percent of the food intake for each respective fatty acid.
Still, Fagherazzi and Dow cautioned that their investigation showed an association, not a cause-and-effect relationship.They also said "it remains unclear" whether the same risk association might be seen among men as well. And they noted that because their studies focused exclusively on food intake, they could not comment on whether fatty acid supplementation (such as fish oil supplements) might also be linked to similar elevations in diabetes risk.
"There is oodles of evidence for why those things are good for us," Sandon said. "But if I were a big meat eater, I would cut back."
