Answer

No. In Jain Dharma, one should not intentionally eat nails or skin.

Explanation

Jain conduct emphasizes purity, self-control, and carefulness in food and bodily habits. Nails and skin are not considered proper food, and intentionally eating them is an impure habit.

Also, biting nails or chewing skin can involve:

• Carelessness toward the body
• Impurity and unhygienic behavior
• Lack of self-restraint
• Possible harm to small living beings or microorganisms

If it happens accidentally, that is different from doing it knowingly and repeatedly.

Spiritual Understanding

Jain Dharma teaches awareness in every action. Even small habits matter because they shape discipline, cleanliness, and inner control. Avoiding such habits supports samyam — self-restraint.

Takeaway

A Jain should avoid eating nails or skin intentionally and try to overcome the habit with awareness, cleanliness, and self-control.
