Omega-3 fatty acids are essential to human nutrition and are thus termed essential fatty acids; however, the human body is unable to efficiently synthesize these. Omega-3 must be consumed within the diet to appropriately intake the necessary amount for a healthy diet (Eisemann and Kim, 2013). Omega-3 can be converted into EPA and DHA, which is also a very inefficient process. EPA and DHA provide extreme health benefits so it is imperative that humans are able to incorporate these into their diets, either through consumption or supplementation. There have been studies that showed increased consumption of a-linolenic acid does not result in increased levels of DHA. The overall conversion from a-linolenic acid to EPA was studied to be around .2% and near .05% for DHA. In another study, increased intake of EPA did not result in increased levels of DHA, which suggest low efficiency in their conversion as well. Most research suggest that desiring increased levels of a-linolenic acid, EPA, or DHA, must be achieved through increased levels of dietary consumption with these fatty acids in higher concentrations (Berquin et al., 2008). There are many health benefits to consuming omega-3 that vary from reduction in cardiovascular disease, decrease in depression, positive behavioral changes in children, as well as fetal development in pregnant women.
Since omega-3 fatty acids are essential and cannot be synthesized by the body, humans must ingest the appropriate amounts in order for proper and healthy function (Eisemann and Kim, 2013). EPA and DHA are derived from omega-3 and are from fish-oil. In numerous studies, both EPA and DHA are shown to provide health benefits. Nearly 25% of all Americans within the western world do not consume fish, w...

... appropriate amounts of omega-3 in their diets or supplement. EPA and DHA are converted from a-linolenic acid, which is a large makeup of omega-3 fatty acids, and is a relatively inefficient process (Berquin et al., 2008). These molecules have numerous health benefits and have been studied in numerous research experiments including: cancer, fetal brain development, depression, and cardiovascular disease. Since nearly 25% of western countries’ population does not eat fish, which is a very good source of omega-3, it has been supplemented into other foods through fish oils. There is also an imbalance of omega-6 to omega-3 ratio which has led to increased levels of cardiovascular disease in many adults (Lucas, 2006). There should be a strong effort to include the appropriate blend of omega-3 in the human diet as a method to increase health and maintain well balanced diet.
