Making sure fish ends up on your dinner plate a couple of times a week may be a good way to cut your risk for developing heart disease, but it may not do the same for diabetes.

Diet is a key factor in preventing the onset of diabetes in adults, but how omega-3 fatty acid intake impacts diabetes risk is still unresolved.
To examine the ties between fish and omega-3 fatty acid intake and the development of diabetes, American researchers followed 152,700 women enrolled in the Nurses' Health Study and 42,504 men enrolled in the Health Professionals Follow-Up Study. Overall, 9,380 cases of adult-onset diabetes developed among these healthcare workers during up to 18 years of follow up.
After adjusting for lifestyle and other dietary factors, plus body weight, family history of diabetes, and menopausal status and hormone use when applicable, an increased diabetes risk was noted in those consuming higher levels of omega-3 fatty acids.
Diabetes was 1.17 times more likely among people who ate fish 2 to 4 times a week, and 1.22 times more likely among those who ate fish 5 or more times a week, relative to those who ate lesser amounts of fish.
There was no evidence of reduced risk for diabetes among adults who ate more fish, or the essential omega-3 fatty acids obtained primarily from seafood. Rather, the above findings suggest that eating 2 or more servings of fish a week may slightly increase diabetes risk.
Further studies are required to determine the mechanisms behind the observation that high fish intake may raise diabetes risk.
