Free Fatty Acid Effects In Type 2 Diabetes
Repositioning Omega-3 Fatty Acids For Treatment Of Glycaemia And Cardiometabolic Disease
Omega-3 fatty acids are natural fats found in foods such as oily fish and flaxseed. Omega-3 fatty acids have been found to have positive effects on cardiovascular health, but there is less evidence on if they can help manage blood glucose in individuals with both cardiovascular disease and type 2 diabetes.
This study will investigate whether the beneficial effects found in omega-3 fatty acids such as lowered blood glucose and reduced inflammation - both of which are important for managing type 2 diabetes and cardiovascular disease, can be beneficial for individuals with type 2 diabetes. As omega-3 fatty acids are already found naturally in food, and are already available as supplements, they could be a safe option to help manage these diseases.
The aim of this study is to investigate if omega-3 fatty acids can slow down the progression of type 2 diabetes and reduce the risk of cardiovascular disease in individuals with type 2 diabetes.

Waist-to-hip circumference compared to placebo administration
Tidsramme: From baseline to 28 days of treatment
|
Waist circumference (in cm between the lower rib and iliac crest) and hip circumference (in cm at the widest part of the hips/buttocks) will be combined to calculate waist-to-hip circumference

Homeostatic Model Assessment of Insulin Resistance (HOMA-IR) index compared to placebo administration
Tidsramme: From baseline to 28 days of treatment
|
Insulin resistance will be measured by calculating HOMA-IR using the formula: HOMA-IR = fasting plasma glucose (mg/dL) x fasting plasma insulin/405.
Higher values indicate greater insulin resistance.
This is a derived continuous index with no fixed minimum or maximum value.
