In Jainism, brinjal (baingan / eggplant) is generally avoided by many Jains.

Why it is avoided

• Jain dharma emphasizes ahimsa — non-violence toward all living beings.
• Brinjal is considered to have many tiny seeds and is believed to involve more subtle forms of life compared with many other vegetables.
• Because of this, many Jains feel it creates greater violence in eating and preparing it.
• It is also traditionally avoided in many Jain households on religious days, fasting days, and during strict vrat.

Tradition

• In most Jain communities, brinjal is treated as a forbidden or avoided food item.
• This is a customary dietary discipline based on ahimsa and purity of conduct.
• Some practices may differ by community, region, and level of observance, but the general Jain view is to avoid brinjal.

Simple conclusion

For a Jain following a strict ahimsa-based diet, brinjal is usually not eaten.
