Recent research has shown that long-chain omega-3 fatty acids derived from fish and fish oils, may help reduce the risk of type 2 diabetes.
The study is being carried out at the University of Eastern Finland under the name Kuopio Ischaemic Heart Disease Risk Factor Study (KIHD).
The researchers went through the serum omega-3 fatty acid concentrations of 2,212 men between 42 and 60 years of age at the onset of the study.
During a follow-up of 19.3 years, 422 men were diagnosed with type 2 diabetes.
The risk of men in the highest serum omega-3 fatty acid concentration group to develop type 2 diabetes was 33 percent lower than the risk of men in the lowest concentration group.
Serum long-chain omega-3 fatty acid concentrations were used to divide the subjects into four categories.
The study sheds new light on the association between fish consumption and the risk of type 2 diabetes. A well-balanced diet should include at least two fish meals per week, preferably fatty fish.
The study has been published in journal Diabetes Care.
