The Claim

Higher consumption of fermented dairy products is associated with a 35% lower risk of all-cause mortality in middle-aged adults over a 12-year follow-up period, with a hazard ratio of 0.65 (95% CI: 0.47–0.90) after adjustment for lifestyle, diet, and BMI.

In plain English

People who ate more fermented dairy products like yogurt and cheese over 12 years had a 35% lower risk of dying from any cause compared to those who ate less, after accounting for lifestyle, diet, and body weight.

See the scientific wording

In a cohort of 4,526 middle-aged adults followed for up to 12 years, higher consumption of fermented dairy products (such as yogurt and cheese) was associated with a 35% lower risk of all-cause mortality, with the highest intake group showing a hazard ratio of 0.65 (95% CI: 0.47–0.90) after adjusting for lifestyle, diet, and BMI, suggesting a potential protective association that warrants further investigation.

Why this might work

Good bacteria from fermented dairy products produce compounds that calm down harmful inflammation in the body and help regulate blood sugar and fat levels, which keeps organs working properly and lowers the chance of dying from any cause.

1 study
  1. Study: Consumption of dairy products and associations with incident diabetes, CHD and mortality in the Whitehall II study.

    People who ate more yogurt and cheese were less likely to die during the study, even when scientists accounted for other healthy habits — suggesting these foods might help people live longer, though it doesn’t prove they cause it.
