A Fish Tale? More on That Seafood, Melanoma Study
A study published last week linking the consumption of fish to melanoma had sushi eaters looking up the number of the nearest dermatologist. But experts said the findings had several important limitations and that no one should change their diet based on the results. At the beginning of the study people reported how much fish they had consumed over the previous year, which varied widely by person. Then researchers tracked participants for 15 years, counting who developed cancer and who did not.
@md-aslam NIH researchers never checked to see how their diet changed over time, as this was a study meant to observe changes in health status starting from a baseline point. The researchers assumed that the level of fish intake recorded at the beginning of the study remained steady.
