Association between planetary health diet and cardiovascular disease: a prospective study from the UK Biobank
- Prospective cohort study
Authors' conclusion
In this large cohort of middle-aged and older British adults, adherence to the PHDI was associated with a lower risk of CVD.
Study context
- Population
- Individuals aged 40–69 years from the UK Biobank, free of cardiovascular disease (CVD) at 2009–12, followed up to 20215,257 incident CVD cases
- Participants
- 118,469 individuals
- Exposure
- Highest vs lowest quartile of Planetary Health Diet Index (PHDI) adherence
- Outcome
- Incident CVD (primary MI or stroke)
- Follow-up
- 9.4-year follow-up

Observational data: associations, not effects.
Further findings
| Outcome | HR (95% CI) | |
|---|---|---|
| MI · multivariable-adjusted | 0.88 (0.80–0.97) | |
| Stroke · multivariable-adjusted | 0.82 (0.70–0.97) | |
| 0.512Hazard ratio (log scale) |
Sensitivity analyses (excluding T2DM, ≥3 diet assessments, excluding CVD cases in first 3 years)
- Results remained robust
PHDI food group components
- Strongest association with lower CVD risk: higher whole grains, whole fruits, fish; lower added sugars and fruit juices
