Which food is highest in omega-3 fatty acids?

Salmon is known to be one of the best sources of omega-3 fatty acids, particularly in the forms of EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid). These essential fatty acids are crucial for various bodily functions, including heart health, brain function, and inflammation reduction. Salmon, especially fatty varieties such as wild-caught salmon, has a high concentration of these beneficial nutrients, making it an excellent choice for increasing omega-3 intake.

Other options provided do not match the omega-3 concentration found in salmon. Bok choy, while nutritious, is primarily a source of vitamins and minerals but contains only trace amounts of omega-3. Coconut oil is mainly composed of saturated fats and lacks significant omega-3 fatty acids. Chicken offers some healthy nutrients but is not a notable source of omega-3s compared to fatty fish such as salmon. Thus, salmon stands out as the food highest in omega-3 fatty acids among the given choices.
