A team of Swedish scientists recently concluded a fifteen year study on the relationship between fatty or lean fish consumption and the risk of kidney cancer; the study revealed that those who ate on average more than one serving per week of fatty fish had 44 percent less risk for developing renal cell carcinoma, the most common form of kidney cancer. Though all previous studies on the relationship between fatty fish and the prevalence of kidney cancer have been inconclusive, the Swedish scientists attribute the lower rate of kidney cancer to increased intake of omega 3 fatty acids. Lean fish is rarely rich in omega 3’s, and those in the study who ate lean fish had the same risk for developing renal cell carcinoma as those who ate no fish at all.
