The Claim

Dairy consumption is associated with a very small increase in mortality risk, with rate ratios near 1.04 and confidence intervals that barely exclude 1.00, suggesting that any observed effect is minimal and potentially confounded by unmeasured lifestyle factors.

Supports is higher

Support is ahead, but a single strong opposing study can change this.

In plain English

People who consume dairy have a very slight increase in death risk compared to those who do not, but the difference is so small that it may be due to other lifestyle habits rather than dairy itself.

See the scientific wording

The observed associations between dairy consumption and mortality are weak, with rate ratios near 1.04 and confidence intervals barely excluding 1.00, indicating that any effects are small and may be influenced by unmeasured lifestyle factors.

Why this might work

Eating more dairy raises the amount of saturated fat in the blood, which increases bad cholesterol and causes slow inflammation in blood vessels, slightly raising the chance of death over time.

What the research says

1 study
  1. Study: Dairy consumption and 10-y total and cardiovascular mortality: a prospective cohort study in the Netherlands.

    The study found that eating a little extra butter might slightly raise the chance of dying, but the increase is so tiny it could just be due to other habits like smoking or exercise. For most people, dairy didn’t seem to affect lifespan at all.
