Mediterranean Diet Sustainability and Health Impacts
Summary
The Mediterranean diet combines a predominantly plant‐based nutritional profile with moderate consumption of fish, dairy and minimal red meat, underpinned by extra-virgin olive oil as the principal fat source. Its health benefits extend from cardiovascular protection and improved metabolic profiles to reduced incidence of neurodegenerative diseases and certain cancers. Concurrently, this dietary pattern exerts a lower environmental burden through reduced greenhouse gas emissions, land use and water consumption compared with more animal-centric models. The inherent biodiversity of the Mediterranean food system, with its array of local cereals, legumes, fruits, vegetables, herbs and nuts, sustains agro-ecological resilience and nutrition security. Social and cultural practices such as shared meals, seasonal eating and minimal processing strengthen community cohesion and reinforce dietary adherence. Growing evidence supports this model as a scalable framework for global health promotion and planetary stewardship, with practical implications for dietary guidelines, food policy and sustainable supply chains.

Mediterranean Diet Sustainability and Health Impacts publication trend
The graph below shows the total number of articles in mediterranean diet sustainability and health impacts across all publications each year (not limited to Nature Index journals).
Technical terms
Biodiversity: Variation among living organisms within a specific ecosystem or region, encompassing species and genetic diversity.
Greenhouse gas emissions: Release of gases such as carbon dioxide and methane that trap heat in the atmosphere, contributing to climate change.
Eutrophication: Enrichment of water bodies with nutrients (nitrogen and phosphorus) that stimulates excessive algal growth and depletes oxygen.
Carbon footprint: Total greenhouse gas emissions, expressed in carbon dioxide equivalents, associated with an activity, product or diet.
