(WebMD) Eating fatty fish — but not lean fish or shellfish — cuts

women's risk of kidney cancer, a Swedish study shows.

 

A recent overview of all existing dietary studies recently found no

proof that eating fish fights cancer. But that study didn't

differentiate fatty fish — which are full of healthy omega-3 fatty

acids and vitamin D — from lean fish.

 

Alicja Wolk, DMSc, of the Karolinska Institute in Stockholm, Sweden,

and colleagues looked at more than 15 years of data on 61,433 women

aged 40 to 76. The women filled out food-frequency questionnaires.

 

Women who ate fatty fish at least once a week had a 44 percent lower

risk of kidney cancer than those who ate no fish. Those who

consistently ate lots of fatty fish over a 10-year period had a 74

percent lower risk of kidney cancer.

 

" Our study suggests that consumption of fatty fish may reduce the

occurrence of [kidney cancer] in women, " Wolk and colleagues

conclude. " In contrast, consumption of lean fish or other seafood

was not associated with the risk of [kidney cancer]. "

 

Fatty fish, in the Wolk study, included salmon, herring, sardines,

and mackerel. Lean fish included cod, tuna, and fresh-water fish.

 

Of course, this study simply finds a link between lower kidney-

cancer risk and eating fatty fish. It doesn't prove fatty fish

prevents cancer. But eating fatty fish once or twice a week is good

for you. So there's no harm in making sure it's part of your diet.

 

The study appears in the Sept. 20 issue of The Journal of the

American Medical Association.
