Description

Research to define and convey seafood risks and benefits, such as cultural significance and nutritional value, is critical to making scientifically informed regulatory decisions. Furthermore, life stage determinants and genomic factors can influence susceptibility and alter the risks and benefits of seafood consumption. We have collaborated on seafood consumption surveys among Asian-American women of childbearing age, in particular Korean and Japanese populations, in the Puget Sound area. This is a critical study to consider the overall dietary patterns in determining the benefits and risks from seafood consumption to better understand potential impacts when fish consumption advisories limiting ingestion are proposed. This research directly informs how we should consider issuing fish advisories. Results show disproportionate seafood benefits and ingestion rates, and emphasize the need for research details. For example Korean populations consumed more shellfish than Japanese populations although the consumption of finfish was approximately the same between two populations. A large percentage of these populations did not consume recommended amounts of omega-3 fatty acids even though they consume seafood at a rate much higher than the U.S. average population. Nutritional needs vary across life stage and by pregnancy status, but so do toxicological impacts. When factored in with the role of individual genetic differences and epigenetic determinants of health over time, one is not surprised to find that there is much to consider when both defining and conveying the positive and negative aspects of seafood. This work helps guide regulatory processes at the intersection of nutrition, toxicology, and risk assessment.
