Omega-3 boost
One of the arguments used to promote oily fish is that it provides the long chain omega-3 fats EPA and DHA important for health. Omega-3 from plants (ALA) is converted in the body to EPA and DHA but conversion rates may be low. However, new research indicates that vegetarians convert ALA at a better rate than fish-eaters. This may explain why fish-eaters and non fish-eaters have a smaller than expected difference in omega-3 levels.
Welch et al., 2008. Estimated conversion of alpha-linolenic acid to long chain n-3 polyunsaturated fatty acids is greater than expected in non fish-eating vegetarians and non fish-eating meat-eaters than in fish-eaters. Journal of Human Nutrition and Dietetics. 21 (4) 404.
