People who eat cheese have the same or lower risk of dying from any cause compared to those who eat less cheese.
See the scientific wording
Cheese consumption is associated with neutral or reduced all-cause mortality.

What the research says
14 studies reviewedSupporting (13)
Cohort StudyHuman2023
This study found that people with colon cancer who ate more cheese and other full-fat dairy after diagnosis were more likely to die sooner. This suggests cheese might not be harmless — it could even be risky for some people.
Systematic Review With Meta-AnalysisMeta-analysis2026
People who eat a small amount of cheese each day don’t seem to have a higher chance of dying from any cause, and they might even have a slightly lower risk of dying from heart disease. So cheese doesn’t appear to be harmful.
Cohort StudyHuman2021
The study found that people who ate cheese didn’t have a higher or lower chance of dying compared to those who ate less — so cheese doesn’t seem to make you more or less likely to die. This matches the claim that cheese is neutral for lifespan.

Cohort StudyHuman2019
The study found that people who ate a lot of dairy, like milk and cheese, were slightly more likely to die early than those who ate less. It didn’t single out cheese, but the overall trend doesn’t show cheese helping people live longer.
Quality-weighted scoring: we follow the GRADE framework — each study is rated High, Moderate, Low, or Very Low based on study design, methodology rigor, and risk of bias. A single high-quality RCT can outweigh several weaker observational studies.
Scores reflect study quality, not just count.
Cheese contains compounds that reduce inflammation in the blood and prevent calcium from building up in artery walls. This keeps blood vessels flexible and reduces damage to organs, which lowers the chance of dying from heart disease, stroke, or other chronic conditions.
