The best sort of fat you can get is one that’s high in omega-3 fatty acids. There are two common omegas: omega-3 fatty acids and omega-6 fatty acids. Omega-3s are found in fatty cuts of fish, egg yolks, avocados, and nuts, as well as a few other foods, and they can also be supplemented. Foods that are high in omega-3s are considered to be good fats.
