    ..The main sources of long-chain PUFA were fish and seafood, and meat, poultry, and eggs. From a public health perspective, it seems desirable to tackle the problem of low n-3 PUFA intake. ..

    ..Furthermore, the replacement of meat products rich in SFA by poultry would increase the arachidonic acid intake. As well, fatty fish consumption needs to be increased, as it is a rich source of long-chain n-3 PUFA. ..

    ..Only 11.6% of the population sample reached an intake level of 500 mg EPA&DHA per day. The study showed that other strategies will be needed to increase the EPA&DHA intake in the long term. ..
