Plant-based diets and long-term health: findings from the EPIC-Oxford study
Proceedings of the Nutrition Society review summarising EPIC-Oxford: vegetarians and vegans typically show lower BMI, LDL cholesterol, and blood pressure than comparable regular meat-eaters, alongside lower bone mineral density and higher vigilance needs for vitamin B12, vitamin D, calcium, and iodine—especially in vegans.
Scope
EPIC-Oxford long-running cohort used here as a plant-based vs omnivorous risk-factor lens (vegetarian = plant-based + dairy/eggs; vegan = fully plant-based).
Risk-factor themes (review abstract)
- Anthropometrics / lipids / BP: vegetarians/vegans commonly have lower BMI, lower serum LDL-C, and lower blood pressure than comparable regular meat-eaters.
- Bone: lower BMD reported in plant-based groups—interpret next to calcium / vitamin D / protein adequacy and activity.
- Micronutrients: authors flag B12, vitamin D, calcium, iodine as higher-risk insufficiency domains—especially vegans.
Evidence hygiene
This entry is cohort/review orientation for intermediate phenotypes—pair with hard-outcome diet RCTs (e.g. PREDIMED republication) and bone-fracture supplement meta-analyses when users ask about events, not biomarkers alone.

Outcomes
- EPIC-Oxford synthesis: vegetarians and vegans typically have lower BMI, LDL cholesterol, and blood pressure than comparable regular meat-eaters, with lower bone mineral density and higher micronutrient vigilance (B12, vitamin D, calcium, iodine), especially for vegans.
