The Claim

Total intake of bacterial fermented foods, including dairy, vegetables, and meat, is not significantly associated with all-cause mortality, cancer mortality, or cardiovascular disease mortality in a 15-year follow-up of 34,409 Dutch adults after adjustment for age, sex, smoking, BMI, physical activity, education, and intake of fruit, vegetables, and alcohol.

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

In a 15-year study of over 34,000 Dutch adults, consuming bacterial fermented foods such as yogurt, sauerkraut, and fermented meats showed no measurable difference in the risk of dying from any cause, cancer, or heart disease, after accounting for other lifestyle and dietary factors.

See the scientific wording

Total intake of bacterial fermented foods, including dairy, vegetables, and meat, showed no significant association with all-cause, cancer, or cardiovascular disease mortality in a 15-year follow-up of 34,409 Dutch adults after adjustment for age, sex, smoking, BMI, physical activity, education, and intake of fruit, vegetables, and alcohol.

Why this might work

Eating fermented foods like yogurt, cheese, and sauerkraut introduces bacteria and metabolites into the gut, but these do not change blood sugar, fat levels, inflammation markers, or immune activity enough to affect how long people live.

  1. Study: The relationship between fermented food intake and mortality risk in the European Prospective Investigation into Cancer and Nutrition-Netherlands cohort

    This big study found that people who ate lots of yogurt, cheese, and sauerkraut didn’t live longer or shorter lives than those who ate less — after accounting for other healthy habits. So, eating fermented foods doesn’t seem to make a big difference in how long people live.
