Planetary health diet, other plant-based diets and risk of type 2 diabetes: a prospective study from the UK Biobank.
Article in Cardiovascular diabetology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundType 2 diabetes remains a major global health concern, and plant-based diets (PBD) offer substantial preventive value. The Planetary Health Diet Index (PHDI) captures adherence to an environmentally sustainable PBD with potential metabolic benefits. However, evidence on its association with type 2 diabetes risk remains limited, notably in comparison with other preexisting PBD. The objective of this study was to evaluate the association between adherence to the PHDI and type 2 diabetes risk in a large British adult cohort and compare it to other well-known PBDs.
methodsThis analysis included 112,032 participants aged 40-69 years from the UK Biobank who were free of type 2 diabetes and cardiovascular disease at baseline (2009-2012) and were followed until 2021. Dietary intake was assessed using at least two 24-h dietary recalls, and PHDI scores (range: 0-130) were computed based on adherence to 14 food groups recommendations. The other PBDs (alternate Mediterranean Diet score (aMED), healthful plant-based index (hPBD), Dietary Approach to Stop Hypertension (DASH), and Alternate Healthy Eating Index (AHEI-2010)), were estimated using established methodologies. Incident type 2 diabetes was ascertained through clinical records, hospital admissions, and self-reporting. Cox proportional-hazards regression models were used to estimate hazard ratios (HR) and 95% confidence intervals (CIs), adjusting for key confounders.
resultsDuring a median 9.4-year follow-up, 2666 cases of type 2 diabetes were identified. When comparing participants in the highest versus the lowest quartile of PHDI adherence, the multivariable-adjusted HR (95% CI) for type 2 diabetes was 0.57 (0.50, 0.64), which was more pronounced than that observed for the aMED: 0.70 (0.62, 0.78) and hPDI: 0.64 (0.57, 0.72) and similar to DASH: 0.58 (0.51, 0.65); AHEI-2010: 0.59 (0.53, 0.67). Further adjustment for BMI led to a 13-19% attenuation of the association. High consumption of vegetables and fish, and limited intake of red/processed meats and added sugars were associated with reduced type 2 diabetes risk.
conclusionsIn this large cohort of British adults, higher adherence to the PHDI was associated with a substantially lower risk of type 2 diabetes, with effect sizes comparable to or greater than those observed for other well-known PBDs. These findings support the promotion of the PHDI and PBDs as an environmentally sustainable choice with potential to reduce type 2 diabetes risk.
