Plant-Based Diets Associate With Lower Breast Cancer Risk
A 2026 Frontiers in Nutrition study jointly analyzed UK Biobank and CLHLS cohorts (about 67,045 cancer-free UK participants, 3,397 baseline breast cancer patients, and 7,431 CLHLS participants) to assess plant-based diets and micronutrient intake in relation to breast cancer incidence and mortality. Higher Healthful Plant-Based Diet Index adherence correlated with lower breast cancer incidence (11% reduction) and 28% lower all-cause mortality; several micronutrients were protective while higher sodium increased mortality.
Scoring Rationale
Moderate novelty and robust cohort evidence, but observational design limits causal inference and immediate clinical actionability.
