Although, there has been some controversy regarding the effect of omega-3 fatty acids in diabetes, scientific experts and research studies support the use of fish oil supplementation for patients with type 2 diabetes, suggesting a positive effect on triglyceride levels and no adverse effect on glycemic control.
Diabetes was Shown to be Significantly Suppressed
In a study investigating the effect of long-term administration of EPA (highly purified eicosapentaenoic acid ethyl ester); the incidence of diabetes was shown to be significantly suppressed at an EPA intake level of 0.3g/kg or higher. Furthermore, administration of EPA was shown to decrease the elevation of plasma glucose after an oral glucose load and ameliorate coagulation-related parameters. In addition, ADP (collagen-induced platelet aggregation) and the cholesterol to phospholipids (C/P) molar ratio in platelet membranes were both suppressed at an EPA dose of 0.1 g/kg or higher.
Lowers Blood Pressure and Triacylglycerol Concentrations
According to some researchers omega-3 fatty acids may improve many of the adverse metabolic effects of insulin resistance by lowering blood pressure and triacylglycerol concentrations. Administration of EPA (1800 mg/day for 48 weeks) to patients with type 2 diabetes mellitus resulted in significant beneficial effects on diabetic neuropathy and serum lipids as well as other diabetic complications such as nephropathy and macroangiopathy. EPA was found to improve clinical symptoms (coldness, numbness), the vibration perception threshold sense of the lower extremities, and significantly decrease serum triglycerides as well as excretion of albumin in urine.
Research studies suggest that omega-3 is useful in combating circulation problems associated with diabetes by rendering the walls of the veins and arteries smoother and more elastic.
Reduced Diabetes Risk
According to some researchers DHA (docosahexaenoic acid, an omega-3 fatty acid found in fish oil) has a positive effect on adult-onset diabetes mellitus and various other diseases.
According to Dr. Weil, diets rich in omega-3s can decrease insulin resistance in diabetics.
According to Dr. Michael Colgan, omega-3 fatty acids inhibit adult-onset diabetes.
According to a recently published study in the American Journal of Clinical Nutrition (73:1019-102, 2001), polyunsaturated fatty acids reduce women’s risk of type 2 diabetes.
