The Claim

Dairy consumption is associated with a 22% lower all-cause mortality risk in non-obese individuals (BMI <30), but no such association is observed in obese individuals (BMI ≥30), indicating that obesity modifies the relationship between dairy intake and mortality.

What the research says

Supports is higher

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

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

In plain English

People with a body mass index below 30 who consume dairy have a 22% lower risk of dying from any cause compared to those who do not, but this lower risk is not seen in people with a body mass index of 30 or higher.

See the scientific wording

The protective association between dairy consumption and mortality is stronger in non-obese individuals (BMI <30), with a 22% lower all-cause mortality risk, but absent in obese individuals (BMI ≥30), suggesting obesity may blunt the potential health benefits of dairy intake.

Why this might work

In people who are not obese, compounds from dairy improve how the body uses energy and calm down harmful inflammation, which helps prevent disease and death. In obese people, excess fat blocks these benefits by disrupting energy use and keeping inflammation high.

  1. Study: Dairy Food Intake and All-Cause, Cardiovascular Disease, and Cancer Mortality: The Golestan Cohort Study

    The study found that people who aren’t overweight who eat yogurt and cheese live longer, but this benefit doesn’t show up in people who are obese — meaning being overweight might block the good effects of dairy.
