Lower diabetes risk with higher omega-3s

In a population of 2000 men without type 2 diabetes at baseline, the risk of developing the disease was a third lower in those with the highest serum omega-3 PUFAs after 20 years, compared to those with the lowest omega-3s.

Mercury levels, thought to cause pancreatic islet beta-cell dysfunction, were not associated with type 2 diabetes risk.

Similarly, dietary fish intake taken from four-day food diaries was not associated with diabetes risk.

However, high serum omega-3 PUFAs were not necessarily linked with a healthy lifestyle, being associated with higher BMI, higher alcohol intake and lower fibre intake.
