Doctor: So, based on the guidelines and the WHO stuff, I’d recommend cutting back on the red meat—especially the processed stuff like bacon and sausage. It’s linked to higher risk of heart disease and some cancers.
Patient: Linked how? From actual trials, or just those big observational studies?
Doctor: Mostly the cohort studies. People who eat more red meat show higher rates of cardiovascular events and certain cancers. Usually something like a 10–20% relative risk bump at the high end.
Patient: Those are just associations though, right? The people eating more red meat also tend to smoke more, sit around more, drink more, and eat more junk overall. How cleanly can you separate that? And has any real randomized trial shown that cutting red meat actually prevents heart attacks, strokes, or death?
Doctor: The trials are pretty thin. Most of them just look at cholesterol or blood pressure, not the hard outcomes. The Women’s Health Initiative cut red meat a bit as part of a low-fat diet and basically saw no clear benefit on mortality.
Patient: Right—so the one big trial that actually reduced red meat didn’t move the needle on dying from heart disease or overall mortality? And the shorter trials on lipids and blood pressure are mostly neutral depending on what you’re comparing it to?
Doctor: Yeah. Versus plant proteins you sometimes get a small LDL difference. Versus other animal proteins it’s often a wash.
Patient: And that IARC thing that put processed meat in the same category as cigarettes? One of the actual panelists—a USDA scientist—said it was the most frustrating experience of his career. Weak observational data, ignored trials that didn’t support it, and a lot of people who already had their minds made up.
Doctor: That process has gotten a lot of criticism. The risks were modest and the data weren’t consistent.
Patient: So if I’m eating steak a few times a week, staying active, not smoking, and not living on ultra-processed food… is there solid evidence that cutting back more is going to meaningfully lower my chance of dying from heart disease or cancer?
Doctor: You know what, screw it—eat as much steak as you want. The evidence to avoid it is paper thin, but I have to tell you to avoid it so I can keep my job. Think I’m gonna have steak tonight too!
