In Jain tradition, it is generally considered better to eat with the right hand and to keep eating manners clean and respectful.

Left hand is usually avoided for eating in many Jain households and communities, mainly for discipline, purity, and decorum. However, this is more a custom and etiquette practice than a core universal Jain vow.

So, in short:

• Preferred: right hand
• Usually avoided: left hand
• Reason: cleanliness and traditional conduct

Different Jain families and communities may follow this with different strictness, but the common practice is to eat with the right hand.
