The Claim

Consumption of fermented milk is associated with a 6% lower risk of cancer mortality, while consumption of yogurt is not significantly associated with cancer mortality, indicating that non-yogurt fermented milks or their unique microbial or metabolite profiles may be responsible for the observed reduction in cancer mortality.

In plain English

People who consume fermented milk have a 6% lower risk of dying from cancer compared to those who do not, but people who eat only yogurt do not show this lower risk, suggesting that other types of fermented milk or their specific microbial compounds may be responsible for the effect.

See the scientific wording

Fermented milk consumption is associated with a 6% lower risk of cancer mortality, while yogurt consumption alone shows no significant association with cancer mortality, suggesting that non-yogurt fermented milks or their unique microbial/metabolite profiles may drive this protective effect.

Why this might work

Fermented milk introduces special compounds made during fermentation that change the bacteria in the gut. These changed bacteria produce substances that calm down chronic inflammation throughout the body and reduce damage to DNA, which lowers the chance of cancer developing and spreading.

  1. Study: Fermented foods consumption, all-cause, and cause-specific mortality: a meta-analysis of prospective cohort studies

    People who ate fermented milks like kefir or sour milk had a slightly lower chance of dying from cancer, and this study confirms that. But it didn’t check if yogurt alone is different from other fermented milks, so we can’t say for sure if yogurt is special or not.
