In Jainism, onions, garlic, and other root vegetables are avoided mainly because of ahimsa (non-violence) and the desire for mental purification.

• Killing many lives: Root vegetables are dug up from the ground, which often harms the plant as well as tiny life forms around its roots. Jains believe even small organisms are living beings, so uprooting and eating them increases harm (himsa) compared to above-ground plants.
• Ananthkay (infinite lives): Many root vegetables are thought to shelter many life forms. Eating them is seen as harming many beings in one act.
• Senses and discipline: Certain foods, like onions and garlic, are believed to stimulate passion and disturb calm, which can hinder spiritual focus and self-control.

Traditionally, both Digambar and Shwetambar communities generally avoid root vegetables, though practical dietary choices can vary by household or region.
