Quite many observational studies have associated high red meat consumption with potential risk of colorectal cancer. There are certain relevant associations suggest that people should limit the intake of red meat to certain amount, for instance, 500g per week, particularly processed or overcooked red meat. The object of this paper is to study the case in Canada by using a single log form model to analyze the correlation of red meat consumption and colorectal cancer, adopting the annual data from 1981 to 2010 in Canada Statistics. In addition, there is a statement that white meat is a better substitution for the risky red meat, so in this paper, we also try to find out whether other healthier white meat, such as poultry and fish, can be a good replacement of red meat. According to the result of the analysis in this paper, we find that red meat consumption doesn’t correlate with colorectal cancer strongly, which emphasize a good healthy life style is the main factor to keep cancer incidence low, but not the consumption of some other things.
