Vegetarian consumption, foods, and markets vary widely—from the US and Europe’s meat-alternative growth to India’s longstanding demand. On this page, you’ll connect dietary choices to food systems outcomes, including greenhouse-gas and land-use differences, as well as animal welfare in intensive farming. We also summarize health evidence on cardiovascular and metabolic risks, and show how vegetarian identification differs by country.
