Researchers at Karolinska Institutet in Sweden report  that women who consume oily fish may reduce the risk of developing renal cancer. In this study 61 433 women in the ages 40-76 filled out a questionnaire regarding their eating habits. The results of the study were published in The Journal of the American Medical Association.
The data was collected during the years 1987-1990 and again in 1997. The researchers then compared the data from the questionnaire with data from the cancer registry. The women who had eaten oily fish at least once per week during the period 1987-2004 reduced the risk of renal cancer by 74 percent, compared to those who never ate oily fish. The reason for this could be that oily fish is very rich in vitamine D and the omega-3 fatty acids EPA and DHA.
