Omega-3 information panel essential fatty acids recommended by the American heart association

Omega-3 fatty acids are essential poly-unsaturated fats that help you to maintain a healthy lifestyle. These fats are primarily found in oily fish and some nuts and seeds such as flaxseed or walnuts. They play an important role in supporting your immune system, while also helping to maintain normal vision and brain function. Omega-3's have also been seen to help support a healthy heart and cardiovascular system, as well as aid in childhood development.

Omega-3 fatty acids are considered essential because they cannot be produced by the human body, whilst also performing vitally important roles in brain, heart, and immune system functions. This means humans must consume Omega-3’s from their diet. The American Heart Association recommends Adults eat two servings of fatty fish a week or supplement at least 1 gram of Omega-3s daily to help with general health and wellbeing (Kris-Etherton, et al 2003). 

Omega-3 information panel modern diet has too many Omega-6's high Omega-6 intake is linked to disease

Chemically Omega-3 fatty acids are defined by their placement of a double bond, three carbons away from the omega carbon of the fatty acid chain. Three main dietary Omega-3s exist; Alpha Lipoic acid (ALA), Eicosapentaenoic acid (EPA) and Docosahexaenoic acid (DHA), each with differing double bond placement and chain length, however they all share the Omega-3 double bond. Typically, ALA is found in plant based foods such as flaxseed oil and walnuts, whereas EPA and DHA are typically found from fatty fish sources. 

Omega-3 information panel high Omega-6 intake linked to inflammation reducing Omega-6 increase Omega-3 helps produce balanced immune response

Traditionally the Human diet would consume equal amounts (1:1 ratio) of Omega-3s and their close chemical cousin Omega-6. However, modern diets are becoming heavily overwhelmed with Omega-6 fatty acids, which raises concerns to scientists about the imbalance of the Omega-3 to Omega-6 ratio (Simopoulos, 2002). Currently, some modern diets are consuming up to 30 times more Omega-6 than Omega-3s which can increase your chances of immune or cardiovascular disease and even cancers (Simopoulos, 2006: Okuyama, et al 2006). 

A high Omega-6 diet increases the chances of disease through proinflammatory pathways. In a classical inflammatory response, both Omega-3’s and Omega-6’s are converted into inflammatory compounds by the COX2 enzyme (Smith, 2008). However, Omega-6’s and Omega-3’s produce different inflammatory compounds at different speeds and intensities, with Omega-6’s producing a quicker and higher inflammatory response (Wada, et al 2007). Typically in a diet which consists of a 1:1 ratio of Omega-3 to Omega-6, both will compete for the COX2 enzyme evenly, helping to produce a stable inflammatory response (Simopoulos, 2003). However, it is hypothesized that in a high Omega-6 diet, the inflammatory response is perturbed resulting in excessive and chronic inflammation throughout the body. This is what researchers believe to be the main cause of the increase in the likelihood of immune or cardiovascular disease and even cancers (Simopoulos, 2008). 

Overall, it is important to note that Omega-6s are still essential for general health and wellbeing in the body, thus they must still be consumed in the modern diet. However, understanding how having a 1:1 ratio of Omega-6’s to Omega-3’s can benefit compared to a current modern diet.
