Monday Dec 8, 2008 (foodconsumer.org) -- Consumption
of fat, protein and meat poses no risk for renal cell cancer, a new study
published in the Dec 3 2008 issue of Journal of National Cancer Institute
study led by Lee JE and colleagues from Brigham and Women's Hospital, and
Harvard Medical School showed that the association between the consumption of
fat and animal protein was not found when other factors were adjusted.
case-control studies have suggested that high consumption of mean (all meat,
red meat or processed meat) is associated with an elevated risk of renal cell
current study examined the association based on data from 13 prospective
studies of 530,469 women and 244,483 men for 7 to 20 years.
the entry of the studies, all participants were surveyed by a validated food frequent
A total of 1478 incident
cases of renal cell cancer were recorded in the studies.
researchers discovered statistically significant positive associations or
trends in pooled age-adjusted models for intakes of total fat, saturated fat,
monounsaturated fat, polyunsaturated fat, cholesterol, total protein, and
example, those in the quintile of the highest consumption of total fat and
total protein were 30 percent and 17 percent more likely respectively to be
diagnosed with renal cell cancer than those in the quintile with the lowest
these associations became statistically insignificant after adjusting for other
factors including body mass index, fruit and vegetable intake, and alcohol
instance, after adjusting for other factors, the risk of renal cell cancer was
increased in those who consumed the highest amounts of total fat and total
protein by 10 percent and 6 percent respectively, which the authors said were
Lee et al. said that intakes of red meat, processed meat, poultry or seafood
were not correlated with the risk of renal cell cancer.
concluded that "Intakes of fat and protein or their subtypes, red meat,
processed meat, poultry, and seafood are not associated with risk of renal cell
cell cancer or renal cell carcinoma, a type of kidney cancer, forms in the
lining of very small tubes in the kidney that filter the blood and remove waste
type of kidney cancer is called renal pelvis carcinoma that forms in the center
of the kidney where urine collects.
cancer also includes Wilms tumor - a type of kidney cancer that usually
develops in children under the age of 5.
kidney cancer is expected to be diagnosed in 54,390 men and women in the United
