Omega-3 fatty acids are a group of polyunsaturated fats that are essential nutrients for human health. The human body cannot produce omega-3 fatty acids on its own, so they must be obtained through diet. The three most important omega-3 fatty acids are alpha-linolenic acid (ALA), eicosapentaenoic acid (EPA), and docosahexaenoic acid (DHA). ALA is found in plant-based foods like flaxseeds, chia seeds, and walnuts. EPA and DHA are primarily found in fatty fish such as salmon, mackerel, and sardines, as well as in algae.

These fatty acids play crucial roles in various bodily functions. They are important components of cell membranes, influencing their structure and fluidity. Omega-3s are also involved in reducing inflammation, which is linked to many chronic diseases. They are vital for brain health throughout life, from fetal development to cognitive function in older adults. Additionally, research suggests that omega-3 fatty acids may contribute to heart health by helping to lower blood pressure and triglyceride levels.

Deficiencies in omega-3 fatty acids can have negative health consequences. Adequate intake is generally recommended for overall well-being. Dietary sources are preferred, but supplements containing EPA and DHA are also available for those who do not consume enough fatty fish or have specific dietary needs. It is advisable to consult with a healthcare professional for personalized advice regarding omega-3 intake.
