EPA may correct Vascular Dysfunction in Diabetes


EPAA study evaluate the effects of EPA (eicosapentaenoic acid) on vascular endothelial function and free fatty acid composition.

The outcome is impressive considering the beginning and middle of the study doesn’t say much about the immediate effects of EPA supplementation.

Before we jump into the study – what is endothelial dysfunction in diabetes? It refers to conditions of cardiovascular disease like the vascular tone, cell flexibility, and coagulation of blood cells.

EPA has inhibitory effects on culprits that cause these types of health maladies.  Researchers wanted to see how it works. Patients were  initially evaluated based on cholesterol and forearm blood glow (FBF). They were evaluated  again after taking 1,800 mg of EPA daily. for 3 months.

EPA supplementation did not change cholesterol levels. EPA supplementation restores endothelium-dependent vasodilatation in patients with elevated cholesterol, despite having no effect on lowering the level of cholesterol in the blood.

Although the cholesterol numbers don’t show a change, it is hypothesized that EPA may improve vascular function at least partly because it changes fatty acid composition.

Sources of EPA include fish oil and oily fish like herring, mackerel, salmon, and sardines. It can also be obtained through various types of edible seaweed. Still waters run deep. Bag yourself some seaweed salad or sautéed salmon. Your heart may thank you.
