What is the primary source of omega-3 fatty acids in the diet?

The primary source of omega-3 fatty acids in the diet is fish and seafood. Omega-3s are essential fatty acids that play a crucial role in heart health, brain function, and overall cellular health. Fatty fish, such as salmon, mackerel, and sardines, are particularly rich in eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), which are the two most beneficial forms of omega-3.

While some plant-based foods can provide alpha-linolenic acid (ALA), such as flaxseeds and walnuts, the conversion of ALA to EPA and DHA in the body is inefficient. Therefore, consuming fish and seafood is the most effective way to ensure adequate intake of these more beneficial and readily usable forms of omega-3 fatty acids. Other options, such as red meat, poultry, and dairy products, do not offer significant amounts of omega-3s compared to fish and seafood.
