A study of 2,300 Italians dietary habits found a relationship between high bread eating and renal cell carcinoma. The researchers warn that pasta and rice could also increase the risk and at the same time eating more vegetables could lower a persons risk for this particular type of kidney cancer. The study was first published online in the October 20th edition of the International Journal of Cancer.
The most common kind of kidney cancer is renal cell carcinoma (RCC). Previously researchers found that diet may have contributed to an increased risk for developing renal cell carcinoma. They did not know which foods directly contributed to this increase which has spurred this new study led by Francesca Bravi of the Institute of Pharmacological Research "Mario Negri" in Milan who conducted a large case-controlled study of 2,301 Italians to determine which foods might increase a persons risk.
There were 767 adults that were diagnosed with RCC and 1,534 participant adults that were free of this disease. The study was conducted between 1992 and 2004. There were two controls that were matched based on gender, age range, and location. The researchers collected information from the participants in regards to their lifestyle habits, sociodemographic information, anthropomorphic measures, along with their personal and family health history. They also had the participants complete a 78 item food questionnaire and asked the frequency the person ate each food each week. This food questionnaire collected the average weekly consumption for each item over the previous two years. The researchers took this food data and used statistical analyses.
"A significant direct association was observed for bread consumption (OR=1.94) for the highest compared to the lowest quintile of intake," the researchers report. The more bread the participant ate the higher the chance for RCC. There was also a modest increase for pasta and rice (OR=1.29). There was a decrease risk if a participant ate more poultry, processed meat, and both cooked and raw vegetables.
The researchers believe that the correlation may be related to the high glycemic index of these foods causing more insulin to be released in the blood. They also suggest that the vegetable consumption may have nutrients such as vitamins, carotenoids, flavonoids, and phytosterols that may help prevent the growth of cancer.
The researchers do admit that this study was conducted with a questionnaire format and may not be 100 percent accurate reports from the participants, but they do say since there is such a large sample of participants to collect data from it helps to reflect accurate data.
"Our results confirm that diet may play a role on the risk of RCC, and in particular, a moderate cereal and high vegetable consumption may have a favorable effect on this neoplasm," the authors conclude.
