Question: I read a very interesting news article that David Beckham, an English soccer player, is taking Omega-3 but his wife does not like his halitosis, a kind of mouth odor, by taking the Omega-3. Likewise, many people take Omega-3 regularly for their health. What is Omega-3 and what does it do in our body?

Answer: Omega-3 is one type of fatty acid. As our body is made of many cells, they require nutrients to maintain health (Simopoulos, 2002). Omega-3, an essential nutrient, cannot be produced independently inside our body so people have to take this from foods or outside sources. In fatty acid nomenclature, the number 3 denotes a double bond at the 3rd carbon in the fatty acid chain (Figure 1).


Most importantly, Omega-6 promotes inflammation and Omega-3 counteracts the effects of inflammation caused by Omega-6. According to the research by Heller et al. (2006), maintaining a balance is significantly important in our body’s organs and organ systems such as musculoskeletal system, brain, and eyes. There are 2 types of Omega-3 : DHA and EPA. DHA is an integral building block of nerve cells and EPA replaces some of the Omega-6s in the membranes of cells, and in doing so reduces the production of inflammatory cytokines and increases inflammation-resolving cytokines (Omex, 2012). A cytokine is a substance that is involved in cell signaling to control immune system. Western diets are deficient in Omega-3 fatty acids, and have excessive amounts of Omega-6 fatty acids (Simopoulos, 2002) . This unbalanced diet causes inflammation and further extreme disorders of autoimmune system. In order to balance these two, knowing which foods contain many Omega-3 and consuming them is crucial. One representative example is Salmon. People can eat salmon or otherwise take an Omega-3 supplement, like David Beckham did (Figure 2). It is important to have a well-balanced diet; while we know that Omega-3 is good for our health, taking too much may throw off the balance. I would say “Scientia est potential!; Knowing is a power!”
