Jain vegetarianism is practiced by the followers of Jain culture and philosophy. It is one of the most rigorous forms of spiritually motivated diet on the Indian subcontinent and beyond.
The Jain cuisine is completely lacto-vegetarian and also excludes root and underground vegetables such as potato, garlic, onion etc., to prevent injuring small insects and microorganisms; and also to prevent the entire plant getting uprooted and killed.
