Study shows consumers need more guidance about fish consumption choices
Brigham and Women's Hospital researchers lead a novel evaluation of the factors that influence fish consumption in the United States
In a first-of-its kind summary of fish consumption choices, a team of researchers from Brigham and Women's Hospital has determined that consumers are not getting all the information they need to make informed decisions about fish consumption. Their research is published in the June 1 issue of Environmental Health Perspectives.
The researchers, led by Susan Korrick, MD and Emily Oken, MD of Brigham and Women's Hospital (BWH), summarized the issue of fish consumption choice from toxicological, nutritional, ecological, and economic points of view through evaluation of the scientific literature, public health guidelines and fish consumption advisories made in the United Sates. They found that there is no one place that gives consumers a complete view of the advantages and disadvantages of various fish species.
"Our research shows that there is no one perfect fish when considering nutritional value, toxicity rates and the environmental and economic impact," said Oken. "Consumers are forced to decide what tradeoffs they are willing to make. But as a consumer standing in a store, it is difficult to understand the pros and cons of a fish purchase, because the amount of readily available information is limited."
"Our research highlights the need for the development of clear and simple consumer advice that describes the multiple impacts of fish consumption," said Korrick. "Despite caveats, fish is generally a healthy food; the challenge is providing advice that is both comprehensive and accessible so consumers don't give up eating fish out of frustration."
Additionally, researchers also emphasize the need for policy and fishery management interventions to ensure long term availability of fish as an important source of human nutrition.
This study was funded by a Dartmouth College Superfund Research Program Grant, a Dartmouth Formative Children's Center Grant, the National Institutes of Health (R01 ES 016314), the Harvard Clinical Nutrition Research Center, the Gelfond Fund for Mercury Research & Outreach, the Consortium for Interdisciplinary Environmental Research, SUNY Stony Brook, the Harvard Pilgrim Health Care Institute, the Swiss National Science Foundation, the National Institute of Environmental Health Sciences and the United States Environmental Protection Agency.
This study is a companion to a study led by Dartmouth researcher Margaret Karagas, Ph.D. which examines the current scientific evidence for effects of low-level exposures to methylmercury on neurological and other human health outcomes and also appears in the June 1 issue of Environmental Health Perspectives. Both papers resulted from the Coastal and Marine Mercury Ecosystem Research Collaborative.

Fraunhofer IPA has developed a proximity sensor made from silicone and carbon nanotubes (CNT) which detects objects and determines their position. The materials and printing process used mean that the sensor is extremely flexible, economical and can be used for large surfaces. Industry and research partners can use and further develop this innovation straight away.
At first glance, the proximity sensor appears to be nothing special: a thin, elastic layer of silicone onto which black square surfaces are printed, but these...
3-D shape acquisition using water displacement as the shape sensor for the reconstruction of complex objects
A global team of computer scientists and engineers have developed an innovative technique that more completely reconstructs challenging 3D objects. An ancient...
Physicists have developed a new technique that uses electrical voltages to control the electron spin on a chip. The newly-developed method provides protection from spin decay, meaning that the contained information can be maintained and transmitted over comparatively large distances, as has been demonstrated by a team from the University of Basel’s Department of Physics and the Swiss Nanoscience Institute. The results have been published in Physical Review X.
For several years, researchers have been trying to use the spin of an electron to store and transmit information. The spin of each electron is always coupled...
