Benefits and Risks of Dietary Fish Consumption

Developing models to clarify tradeoffs among risks

Christoph Rheinberger


Diets rich in fish are known to be protective against cardiovascular disease, though fish are also an important source of exposure to toxins including methyl mercury (associated with cognitive deficits to offspring and, potentially, cardiovascular risk to adults) and persistent organic pollutants such as PCBs (associated with cancer). We are developing risk-assessment models to clarify the tradeoffs among these risks and how they depend on the quantities and species of fish consumed as well as the age and sex of the consumer.
