Recent high-quality reviews of red meat and health outcomes, including Type 2 diabetes, heart disease and cancer:
Processed meat intake and chronic disease morbidity and mortality: An overview of systematic reviews and meta-analyses (Using GRADE systematic review methodology)
PLoS One 2019
Conclusion: “Overall, the quality assessments of primary studies of the reviews are generally lacking; the scientific quality of the systematic reviews reporting positive associations between processed meat intake and risk of various cancers, T2D and CVD is moderate, and the results from case-control studies suggest more often a positive association than the results from cohort studies. The overall certainty in the evidence was very low across all individual outcomes, due to serious risk of bias and imprecision.”
