Question:
Answer:

Norwegian dietary studies show that Norwegians consume 91% of EPA and DHA from fish and cod liver oil or other Omega-3 supplements2. The reason why fish constitutes such a good source of the long-chained Omega-3 fatty acids is that they feed on algae containing them. Individuals who have a low amount of EPA and DHA in their diet convert plant-derived Omega-3 into these fatty acids in the body. Unless they have a very high intake of plant Omega-3, they have a much lower level of EPA and DHA in their bodies than what is considered optimal. If they do not take marine oil supplements and rarely eat oily fish, they do not achieve the recommended amount of EPA and DHA in their diets1,3.
