Although usually more expensive, some eggs are high in omega-3 fatty acids because they come from chickens fed an omega-3-rich diet; this type of diet may include soybeans or flaxseed, for example. According to Harvard School of Public Health, omega-3s may protect you against heart disease. Since omega-3 fatty acids are essential for proper fetal growth and development, they are important for pregnant women or women who may become pregnant. If eggs are enriched with omega-3s, the nutrition label generally provides information about the amount of omega-3s provided in each egg.
