Omega-3 Fatty Acids — glossary definition

Omega-3 Fatty Acids

Omega-3 fatty acids are essential polyunsaturated fatty acids that the body cannot produce on its own.

Omega-3 fatty acids are essential fats that must be obtained from food. The most important omega-3 fatty acids are EPA and DHA (from fish) and ALA (from plant sources such as flaxseeds and walnuts).

Omega-3 fatty acids have research-backed anti-inflammatory effects. They support heart health, brain function, and may promote recovery after exercise. Studies also suggest that adequate omega-3 intake may support fat burning and muscle cell insulin sensitivity.

Nutritional guidelines recommend fish at least 2-3 times per week. Good sources include salmon, herring, vendace, and sardines. In vegetarian diets, ALA-form omega-3 is available from flaxseeds, chia seeds, and hemp seeds, but conversion to EPA and DHA is inefficient.

From a weight management perspective, omega-3 supports normal metabolic function and may help reduce inflammatory reactions that slow weight loss. Fish oil as a supplement is a safe alternative if fish consumption is low.
