Taking fish oil every day sounds appetizing doesn't it? Bring back bad memories when you had to wolf down a tablespoon of cod liver oil? Well, the fact is, your mom was thinking about your overall health when she forced that oily concotion down your throat.
The main health benefit of taking daily fish oil is that fact that it is loaded with Omega-3 fatty acids. The main benefit to taking Omega-3 fatty acids is that they are naturally anti-inflammatory. That means that they can aid is diseases and processes that cause inflammation (also known as swelling). Aruguably, inflammatory processes are THE most common cause of many diseases including Celiac's, Rheumatoid Arthritis, Type 2 Diabetes, heart disease, and many more diseases. That can only mean that taking a regular regiment of Omega-3's will help with many of theses diseases.
But Omega-3 fatty acids aren't strictly for reducing swelling. They are also crucial elements in different structures of your body. First of all, most (if not all) cells in your body contain Omega-3 fatty acids in the cell walls and other structures. Secondly, your nerves and nervous system are cushioned by Omega-3 fatty acids. So if you think about it, when you don't get enough Omega-3 fatty acids in your diet (which I can guarantee that at least 90% of the US population does not) you are more prone to cellular malfunction/destruction and nervous system lockdown (that's why fish is typically referred to as "brain food").
There's a reason why drug companies are starting to market prescription fish oils. It's because they have realized how important taking fish oil can be for many different ailments. The fact of the matter is, you don't need a prescription for taking fish oil, we sell them in the clinic and they are readily available at health food stores. Just talk to one of the doctors if you have any questions about what a good fish oil would be. Not to mention there are quite a few choices that eliminate that fishy taste if you're not into seafood.
