Type 2 diabetes risk

Inflammation: red meat specifically

key nuance Low-moderate meta-analysis of trials + cohorts (2025) (AAA)

IMPORTANT: red meat is NOT 'inflammatory' by itself. In controlled trials, at most a MODEST rise in CRP is seen (and mainly with mixed or processed meat and in people who already have cardiometabolic disease); IL-6 and TNF-alpha do not change, and observational studies find no association with CRP, IL-6 or TNF. What is linked to inflammation is the whole PATTERN (sugar, soft drinks, refined grains and, above all, PROCESSED meat), not lean red meat by itself.
