The World Health Organization International Agency for Research on Cancer has similarly indicated that red meat is "probably carcinogenic" and that processed meat is "carcinogenic" to humans (3). These recommendations are based on observational studies at high risk for confounding, which thus limits causal inferences.Johnston and colleagues conducted a rigorous systematic review focusing on cardiovascular and cancer outcomes.
