If you ask those fans of mackerel and salmon why they loved those fish so much and what is omega-3, they will probably give you a long lecture on how important or beneficial essential fatty acids are to your health. They will site a number of studies proving the positive effects of fatty acids on our bodies and how these can be used to treat a variety of conditions, ailments or diseases.
Some, and these are the really omega-3 fanatics, can go on and on and on. From the benefits of omega-3 fatty acids to the preparations and cooking of salmon. At the end you find yourself mumbling and probably cursing why you asked in the first place. However, despite the long lecture, you might notice your friend leaving behind an issue that is often disregarded but is equally important with the benefits of fish oils. And that can be addressed by answering the question: is fish oil harmful?
I am all for the various benefits of fish oils. I don’t discount it, I don’t question the studies nor do I criticize the testimonies from long time users. But personally, I don’t believe that fish oils are purely good. We have this saying that too much of anything is bad for you. The same should apply to fish oils. After researching the internet, reading a number of articles, and a couple of cups of coffee, I found out that fish oils do have some side effects, some even quite harmful.
Among the more minor side effects are diarrhea and that fishy after taste. You will experience these side effects if you too much dosage of fish oils. Commonly doctors would prescribe or recommend a 2 gram intake of fish oil daily at the minimum.
