Omega-3 fatty acids

Definition

Omega-3 fatty acids are essential polyunsaturated fats that play crucial roles in human health, particularly in cardiovascular health, brain function, and inflammation reduction. These fatty acids cannot be synthesized by the body and must be obtained through diet, primarily from sources like fish, flaxseeds, and walnuts. Their significance extends beyond basic nutrition to areas like functional foods and historical food science developments, highlighting their importance in dietary recommendations and health innovations.
