Researchers in Sweden recently examined the association between long-term fish consumption and the risk of renal (kidney) cell carcinoma (RCC) in a group of more than 61,000 women aged 40–76 years who are part of the ongoing Swedish Mammography Cohort, a population-based prospective cohort trial. The purpose of this particular study was to determine whether eating fatty or lean fish over a 15-year period could reduce the incidence of RCC.
After making adjustments for potential confounders, the researchers reported an inverse association with fatty-fish consumption and the risk of RCC. However, no such association was found with lean-fish consumption.
Writing in the September 20, 2006, issue of The Journal of the American Medical Association, the researchers concluded that “consumption of fatty fish may reduce the occurrence of RCC in women.”
The American Heart Association recommends that you eat fish at least twice a week, especially fish that are high in omega-3 fatty acids. Good choices include mackerel, lake trout, herring, sardines, albacore tuna and salmon.
