Bread and Kidney Cancer

 

A diet high in bread intake and low in vegetables may increase the

risk of renal cell carcinoma, the most common type of kidney cancer,

a new study reports.

 

Researchers at the Istituto di Ricerche Farmacologiche "Mario Negri"

in Italy explained that although nutrition and diet have been related

to renal cell carcinoma (RCC), the role of specific foods or

nutrients on this cancer is still controversial.

 

The case-control study evaluated the relation between a wide range of

foods and the risk of RCC. Between 1992 and 2004, researchers

interviewed 767 patients (494 men and 273 women) under the age of 79

with incident, histologically confirmed RCC and 1,534 controls (988

men and 546 women) admitted to the same hospitals.

 

Patients completed a validated and reproducible food frequency

questionnaire including 78 foods and beverages. There was a separate

section on alcohol drinking that was used to assess patients' dietary

habits two years before diagnosis or hospital admission.

 

Researchers obtained multivariate odds ratios (OR) after allowance

for energy intake and other major confounding factors. A significant

direct trend in risk was found for bread and a modest excess of risk

was observed for pasta and rice, and milk and yogurt. Poultry,

processed meat and vegetables were inversely associated with RCC

risk. No relation was found for coffee and tea, soups, eggs, red

meat, fish, cheese, pulses, potatoes, fruits, desserts and sugars.

 

The study concluded that a diet rich in refined cereals and poor in

vegetables may have an unfavorable role on RCC.

 

The U.S. Department of Agriculture (USDA) recommends a diet that

emphasizes fruits, vegetables, whole grains and fat-free or low-fat

milk and milk products; includes lean meats, poultry, fish, beans,

eggs and nuts; and is low in saturated fats, trans fats, cholesterol,

salt (sodium) and added sugars.
