The Claim

Intake of animal protein is not significantly associated with all-cause mortality, cardiovascular mortality, or cancer mortality when adjusted for other dietary and lifestyle factors, based on pooled data from prospective cohort studies.

In plain English

Eating animal protein does not show a clear connection to increased risk of dying from any cause, heart disease, or cancer when other diet and lifestyle factors are taken into account.

See the scientific wording

Intake of animal protein is not significantly associated with all-cause, cardiovascular, or cancer mortality, based on pooled data from 11, 8, and 9 prospective cohort studies respectively, indicating that animal protein sources alone do not show a clear link to increased death risk when adjusted for other dietary and lifestyle factors.

Why this might work

Eating animal protein does not increase the risk of dying from heart disease, cancer, or other causes because it does not trigger harmful changes in cholesterol, inflammation, or cell growth signals that lead to disease. The body processes animal protein in a way that keeps these systems stable, especially when other diet and lifestyle factors are accounted for.

1 study
  1. Study: Dietary intake of total, animal, and plant proteins and risk of all cause, cardiovascular, and cancer mortality: systematic review and dose-response meta-analysis of prospective cohort studies

    This study found that eating more meat, dairy, or eggs didn’t make people more likely to die early, even after considering other lifestyle habits. So, animal protein alone doesn’t seem to increase the risk of dying from heart disease, cancer, or other causes.
