Omega 3s

Omega 3s have numerous health benefits

most notably in the prevention of cardiovascular disease by lowering triglycerides, regulating cholesterol, lowering blood pressure and preventing the build of atherosclerotic plaques. There is also evidence that omega 3s can combat mental disorders and their progression, reduce inflammation, reduce the risk of autoimmune conditions, and are also associated with lowered cancer risks.

Omega 3 supplements

Good sources of omega-3s and omega-6s should be consumed in the proper ratio. Omega-6 fatty acids compete with omega-3s and can inhibit their effect. Ideally the ratio of omega-6 to omega-3 should be around 2:1, but the typical Western diet is closer to 16:1 due to processed foods and oils. This imbalance may be responsible for a number of inflammatory diseases such as heart disease and type 2 diabetes, and play a key role in the development of obesity.

What we test

Omega Fatty Acid Profile

This omega 3 index blood spot test measures the levels of essential fatty acids and their ratios that are critical to good health.

This blood spot test measures:

The omega-3 index is the sum of the fatty acids Eicosapentaenoic Acid (EPA) and Docosahexaenoic Acid (DHA) in red blood cell membranes, and is expressed as a percentage.

Excessive amounts of omega-6 fatty acids and a very high omega 6: omega 3 ratio (as is found in today's Western diets) promote the development of many diseases, including cardiovascular disease, cancer, and inflammatory and autoimmune diseases. Increased levels of omega-3 fatty acids (a low omega 6: omega 3 ratio) exert suppressive effects.

The AA/EPA ratio is considered the best marker of cellular inflammation in the body. It represents the ratio of the omega-6 fatty acid arachidonic acid (AA) and the omega-3 fatty acid eicosapentaenoic acid (EPA).

Trans fatty acids (trans fats) in our blood come only from the food we eat, with the vast majority being from partially hydrogenated vegetable oils. Consumption of industrially-produced trans fats has been linked to poorer heart health.

The most advanced strategy for coronary risk assessment is a ‘multi-marker’ approach which combines several risk factors, rather than only measuring the traditional markers of high blood pressure, cholesterol, smoking and diabetes.
