Final answer:
The primary sources of EPA and DHA, which are crucial for heart health, reducing inflammation, and brain development, are found in fish like salmon, trout, and tuna, as well as in fish oils, seaweed, and algae.
Step-by-step explanation:
The sources of the long-chain omega-3 fatty acids, EPA and DHA, are primarily found in certain types of fish and seafood. Eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) are essential for many body functions, including heart health, reducing inflammation, and playing critical roles in brain and eye development, particularly in infants. While these omega-3 fatty acids can be synthesized in the body from alpha-linolenic acid (ALA), the conversion is not very efficient, making direct consumption of EPA and DHA important. Thus, intake of fish like salmon, trout, and tuna, or fish oils, which are rich in these omega-3 fatty acids, is beneficial.
Moreover, sources such as seaweed, algae, and fish oils are also good sources of EPA and DHA. For those who do not consume fish, omega-3 supplements might be of benefit, particularly for individuals with an increased risk of cardiovascular disease.
