22 Aug 2019 --- Increasing omega 3 consumption has little or no effect on the risk of Type 2 diabetes, according to research from the University of East Anglia. The World Health Organization (WHO) commissioned this systematic review ahead of the imminent update of its dietary guidance on fats. Other measures of diabetes risk – including blood glucose, insulin and glycated hemoglobin – were unchanged by fish oil consumption. The researchers maintain that people should not be encouraged to take omega 3 oil supplements for the prevention or treatment of diabetes.
