Omega-3 fatty acids are also found in other foods, especially high-fat fish such as salmon , mackerel and herring , but also flaxseed. In no case do omega-3 eggs lower the cholesterol level, because omega-3 fatty acids (O3F) only reduce triglycerides in the body . They also thin the blood.
“One omega-3 egg corresponds to about 7 g of flaxseed, which is certainly the cheapest way to get enough O3F. Because the flaxseeds take the detour via the chicken feed into the animal and then into the eggs, a lot of O3F is lost. Since the high-fat fish salmon and herring are rich in DHA and EPA , the same amounts are covered by consuming around 5 g of these fish. "
