Is it true that eating 50 grams of processed meat daily increases colorectal cancer risk by 18 percent, according to the WHO's IARC?
Yes. One peer-reviewed source states that IARC concluded each 50-gram daily portion of processed meat raises colorectal cancer risk by 18 percent, matching the claim exactly. Several other sources support a processed meat–colorectal cancer link but do not attribute the 18 percent figure to IARC.
