Vette vis reduceert de kans op nierkanker met bijna driekwart.*
Meer dan een keer vette vis, zoals ansjovis, zalm, haring, makreel, forel, sardines of tonijn en de kans op nierkanker reduceert met wel 74% volgens Zweedse onderzoekers. In deze vijftienjarige studie onder ruim 61.000 vrouwen werd gekeken naar de de visconsumptie en het ontstaan van nierkanker. De onderzoekers concludeerde dat zij die regelmatig vette vis aten de kans op nierkanker 44% kleiner was dan zij die geen of alleen magere vis zoals kabeljauw, tarbot, schol en tong aten. Zij die gedurende meer dan 10 jaar wekelijks vette vis aten reduceerde de kans op nierkanker wel tot 74%.
Zowel
de omega-3 vetzuren EPA en DHA en vitamine D die volop in vette vis zitten
zullen hiervoor verantwoordelijk zijn.
De verwachting is dat wereldwijd jaarlijks ongeveer 210.000 keer de diagnose
nierkanker wordt gesteld en ruim 100.000 mensen hier aan doodgaan.

Context The
epidemiological evidence that fatty fish consumption may be
associated with the lower risk of several cancers is not consistent
and no studies of renal cell carcinoma (RCC) exist.
Objective To
examine the association between fatty and lean fish consumption and
risk of RCC in women.
Design, Setting, and
Participants The Swedish Mammography Cohort, a population-based
prospective cohort study of 61 433 women aged 40 to 76 years
without previous diagnosis of cancer at baseline (March 1,
1987-December 14, 1990). Participants filled in a food frequency
questionnaire at baseline and in September 1997.
Main Outcome Measure
Incident renal cell carcinoma.
Results During a
mean of 15.3 years (940 357 person-years) of follow-up between
1987 and 2004, 150 incident RCC cases were diagnosed. After
adjustment for potential confounders, an inverse association of fatty
fish consumption with the risk of RCC was found (P for trend = .02),
but no association was found with lean fish consumption. Compared
with no consumption, the multivariate rate ratio (RR) was 0.56 (95%
confidence interval [CI], 0.35-0.91) for women eating fatty fish once
a week or more. Compared with women consistently reporting no fish
consumption, the multivariate RR was 0.26 (95% CI, 0.10-0.67) for
those women reporting consistent consumption of fatty fish at
baseline and 1997 (based on a subset of 36 664 women who filled
in the baseline and 1997 questionnaires, with 40 incident RCC cases
during the 1998-2004 follow-up period).
Conclusion Our
study suggests that consumption of fatty fish may reduce the
occurrence of RCC in women.
