People who eat more dairy—like milk, cheese, and yogurt—tend to have a slightly lower chance of dying from heart disease than those who eat very little dairy.

Appropriate Language Strength
association

Assessment Explanation
The claim uses 'associated with,' which correctly reflects observational study findings. It does not imply causation, which is appropriate since dairy intake is typically measured in cohort or case-control studies. A 7% reduction is a specific, modest effect size commonly reported in nutritional epidemiology. The claim avoids overstatement by not claiming dairy prevents death or that the effect is guaranteed.
More Accurate Statement
“Higher total dairy consumption is associated with a 7% lower risk of cardiovascular disease mortality compared to low dairy intake.”

This study found that people who ate more dairy overall (like milk, cheese, and yogurt) had a 7% lower chance of dying from heart disease compared to those who ate less dairy — which is exactly what the claim says.
