Calcium intake may explain the reduction of colorectal cancer odds by dietary selenium - a case-control study in Poland.

ABSTRACT:

Background

Colorectal cancer (CRC) has been placed among top three cancer sites in high income countries. Although there are several inconsistencies across studies it is widely accepted that diet contributes to approximately 70% of CRC. Several dietary factors have been investigated; however, the knowledge about the role of trace elements and their interplay with other dietary factors in CRC odds is limited. The aim of the study was to estimate the odds ratio of colorectal cancer associated with the content of selenium in diet, and to check whether dietary calcium is a modifier of selenium effect in the population characterized by low selenium intake.

Methods

Face-to-face interviews were used to gather data on dietary habits (by 148-item semi-quantitative food frequency ques
