Choose eggs from cage-free chickens that are fed diets high in the omega-3s, such as flaxseed. These eggs are now widely available and are a much healthier choice than conventional eggs.
According to the University of Nebraska’s Institute of Agriculture and Natural Resources, omega eggs are a type of "designer egg," in which the yolk's fatty acid profile has been modified by altering the hens' diet. Specific lipids—fatty acids and fat soluble vitamins—can be modified in the egg yolk by feeding the hen increased proportions of "good" fatty acids and increased amounts of fat soluble vitamins from dietary sources such as flax seed, fish oil or bioengineered algae. Omega eggs contain increased amounts of n-3 fatty acids and decreased amounts of saturated fatty acids. The increase in yolk polyunsaturated fatty acid (PUFA) is accompanied by a substantial decrease in saturated fatty acids, creating a healthier fat profile.
