yogurt improves cardiovascular health
In plain terms: Is yogurt good for your heart?
Part of: • Yogurt
The evidence is genuinely mixed. Some studies tie yogurt to slightly lower blood pressure and heart risk, but several careful ones find no benefit for yogurt specifically - any effect tends to show up only at high intakes or for 'fermented dairy' in general. A reasonable food to enjoy, but don't count on it as heart protection.

What the evidence shows
Whether yogurt itself helps the heart is genuinely contested. Some meta-analyses and the Framingham cohort suggest fermented dairy and yogurt track with modestly lower blood pressure and cardiovascular risk — but several large, careful analyses find no significant association for yogurt specifically, with any benefit appearing only at high intakes (≥200 g/day) or for the broad 'fermented…

|---|---|---|---|---|
| Ralston RA, Lee JH, Truby H, Palermo CE, Walker KZ 2012 · J Hum Hypertens | meta-analysis | mixed | moderate | SR/meta 5 cohorts: fluid dairy (milk/yogurt) RR 0.92 for elevated blood pressure. |
| Wu L, Sun D 2017 · Nutrients | meta-analysis | mixed | moderate | Meta-analysis of 9 prospective cohorts (14 comparisons, 291,236 participants), highest vs lowest yogurt intake. Pooled CVD RR 1.01 (95% CI 0.95 to 1.08, I2=52%) - a precise null; by outcome CHD 1.04 (0.95 to 1.15), stroke 1.02 (0.92 to 1.13), but composite 'incident CVD events' 0.87 (0.77 to 0.98). Only the 3 comparisons whose top category reached >=200 g/day showed RR 0.92 (0.85 to 1.00), versus 1.06 (0.98 to 1.15) for the 11 below 200 g/day (difference p=0.09); authors describe a dose-response 'trend'. Findings on CVD point both ways (null overall and for CHD/stroke; lower risk in the composite-event and high-dose strata) -> mixed. Observational; Egger p=0.228 (no small-study bias detected). |

Disagree, or know a study we missed?
We grade by evidence, not opinions. The way to weigh in is to point us to a study we haven't cited (check the evidence table above first), or to flag a problem with one we have. Every submission is reviewed; if it holds up, the grade updates and shows in Science Changes Its Mind.
Opens a short form. You'll sign in with Google so submissions are tied to a real account — we don't display your identity, and we only accept a link we can verify (PubMed, DOI, ClinicalTrials.gov).
