The Omega-3 Fatty Acids

Dietary fat is broken down into fatty acids in our body. Fatty acids are important for many bodily functions including energy production, making cell membranes, and for signaling the inflammatory cascade. Among the several types of fatty acids, omega-3s have special benefits. Many people take supplements containing them in the form of fish oil. But, why? Can we get omega-3s in food? Why do we need them? How are they beneficial?
