Where are omega-3 fatty acids commonly found?

Omega-3 fatty acids are essential fats that the body cannot produce on its own, making it necessary to obtain them through diet. They play a crucial role in heart health, brain function, and overall inflammation reduction. Fish oils, particularly from fatty fish such as salmon, mackerel, sardines, and anchovies, are some of the richest sources of omega-3 fatty acids, specifically EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid).

While options such as nuts and seeds do contain omega-3 fatty acids—specifically ALA (alpha-linolenic acid)—they are not as concentrated in omega-3s as fish oils. Red meats typically have a different fatty acid profile, primarily consisting of saturated fats and omega-6 fatty acids rather than beneficial omega-3s. Vegetable oils may contain omega-3s, but they are usually present in lesser amounts compared to fish oils, and many common vegetable oils are more likely to be sources of omega-6 fatty acids.

Therefore, the correct answer highlights the best-known and most concentrated dietary source of omega-3 fatty acids, which is found in fish oils.
