Fish Sauce vs. Fish Oil: Understanding the Difference
Many people often confuse fish sauce and fish oil, assuming that they are the same thing. However, it is important to note that these two products have different characteristics and uses. While both are derived from fish, their consumption and uses are very different. This article aims to provide a comprehensive understanding of the differences between fish sauce and fish oil.
What is fish sauce?
Fish sauce is a condiment commonly used in Asian (East and Southeast) cuisine, as well as in other culinary traditions such as Greek cuisine. It is made by salting and fermenting fish in barrels for an extended period of time, ranging from a few months to up to two years. Oily fish, such as mackerel or anchovy, are often used to make fish sauce. Alternatively, shrimp or krill may be used.
During the fermentation process, the fish breaks down into a savory and fishy black or brown liquid. Some manufacturers enhance the color of the sauce by adding ingredients such as molasses, caramel, or toasted rice. However, the end result should always be a salty, watery, clear sauce. Fish sauce is used not only as a seasoning, but also as a dipping sauce. It is often compared to soy sauce, and some people even consider soy sauce to be a vegetarian substitute for fish sauce. Conversely, many people use fish sauce as a substitute for soy sauce.
Fish sauce adds flavor to a variety of dishes, including marinades, salad dressings, stir-fries, pasta, vegetable soups, and roast chicken. Its strong flavor requires that it be used in small amounts, and it is advisable to taste the dish frequently during preparation. Fish sauce can be stored at room temperature for approximately three to four years, whether the bottle has been opened or not.
What is fish oil?
Fish oil, on the other hand, is extracted from fish tissue and typically comes from oily fish such as tuna, anchovies, mackerel, and herring. It is known for its high content of omega-3 fatty acids, which provide numerous health benefits. To reap these benefits, it is recommended that you eat fish at least once or twice a week or take an omega-3 fatty acid supplement.
Fish oil contains approximately 30% omega-3 fatty acids, with the remainder consisting of other fats. Its consumption has been linked to several health benefits. For example, fish oil may help lower cholesterol and triglycerides, lower blood pressure, prevent arterial plaque formation, and reduce the risk of fatal arrhythmias. It has also been shown to improve brain function, alleviate certain mental disorders, promote eye health, and have strong anti-inflammatory effects.
While fish oil can be consumed by incorporating fish into one’s diet, many people prefer the convenience of taking fish oil supplements in capsule form. This option is especially appealing to those who do not like to eat fish. There are even odorless fish oil supplements that dissolve in the intestines, eliminating any unpleasant taste.
