Which food is known to be a significant source of omega-3 fatty acids?

Salmon is widely recognized as a significant source of omega-3 fatty acids, particularly EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid). These fatty acids are essential for various bodily functions, including cardiovascular health, brain function, and anti-inflammatory processes. Omega-3 fatty acids are not produced by the body and must be obtained through diet, making foods like salmon an important part of a balanced diet.

Notably, the other options do not provide the same level of omega-3 fatty acids as salmon. Coconut oil is primarily composed of saturated fats and lacks omega-3s, while butter predominantly contains saturated fats with very little omega-3 content. Olive oil, though a healthy fat with monounsaturated fats, also has low levels of omega-3 fatty acids in comparison to fatty fish like salmon.
