What is a major source of omega-3 fatty acids?

Omega-3 fatty acids are essential fats that play a crucial role in heart health, brain function, and reducing inflammation in the body. One of the most significant dietary sources of omega-3 fatty acids comes from fish, particularly fatty fish such as salmon, mackerel, sardines, and trout. These fish are rich in two specific types of omega-3s known as EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid), which are readily utilized by the body and have been linked to numerous health benefits, including a reduced risk of heart disease and improved cognitive function.

While other food sources like flaxseeds, chia seeds, and walnuts do contain omega-3s (specifically ALA, or alpha-linolenic acid), they are not as efficient as fish in providing the beneficial EPA and DHA forms of omega-3s. In contrast, options such as red meat, leafy greens, and cereal grains contribute only limited amounts of omega-3 fatty acids, making fish the standout source in the diet. Therefore, the identification of fish as a major source of omega-3 fatty acids is well-supported by nutritional science.
