Meat subtypes and their association with colorectal cancer: Systematic review and meta-analysis.

Frequent consumption of meat, such as beef and lamb, may increase an individual's susceptibility to colorectal cancer.

This study investigated the relationship between the consumption of different types of meat and the odds of developing colorectal cancer by meta-analysis. Twenty-three (23) studies were included in this meta-analysis.

Researchers found out that habitual dietary intake of beef and lamb promoted the development of colorectal and colon cancers. On the other hand, no association was found between beef consumption and rectal cancer. In addition, high dietary ingestion of pork and poultry was also found to have little or no effect on colorectal cancer risk in this study. The findings of this meta-analysis show that high colorectal cancer risk is associated with generous intake of different types of meat, such as beef and lamb.
