The claimWhat Paul actually said
In a BBC Radio 4 interview, McCartney recalls that he and Linda first went vegetarian out of compassion for animals, and that a health rationale was added later as doctors and others raised concerns about high red meat intake. He frames it as one strand among several, not the original motive.

- Pan et al., Arch Intern Med, 2012, two prospective cohorts: higher red meat intake associated with increased mortality
- Zeraatkar et al. (NutriRECS), Ann Intern Med, 2019, systematic review: low-certainty evidence, very small absolute mortality reduction from cutting meat
Why it mattersWhy this matters for longevity
Red and processed meat are everyday staples, so even small per-serving risks scale across a population.
Diet advice is often sold with false certainty; the honest picture here is real but modest.
The evidenceWhat the science says
Pooled analyses of large cohorts associate higher red meat intake with increased all-cause, cardiovascular and cancer mortality, with processed meat showing the strongest and most consistent link.
A 2019 systematic review concluded the certainty of evidence is low and that reducing meat yields only a very small absolute reduction in risk, so the benefit is real but smaller than headlines suggest.
TakeawayThe honest takeaway
The practical lesson
Lean toward less processed and red meat and more plants, but treat it as a modest improvement, not a miracle.

SupplementsThe supplement angle: Protein, iron and vitamin B12
Support a habit, do not replace one
People who cut red meat should make sure protein, iron and B12 come from other foods or, if needed, supplements, since plant diets can run short on B12; this is about adequacy, not added benefit.
Supplements can support good habits. They do not replace sleep, movement, nutrition, or medical care. Talk with your healthcare provider before starting anything new.
