Is eating processed or red meat linked to a higher risk of cancer?

Yes, according to a new report from the American Institute for Cancer Research, a nonprofit based in Washington that studies links between diet and cancer.
As part of a larger, five-year review of more than 7,000 studies, the group’s specialists pored over 87 studies on the potential link between colorectal cancer and red meat, including beef, pork, and lamb. In excessive amounts, “red meat is a convincing cause of colorectal cancer,” the group said, although more research needs to be done on the precise mechanisms.
