In Jain dharma, kāma is mainly a mental and karmic attachment, not just a result of one food. Still, some foods are considered to stimulate the senses and increase restlessness or desire.

Commonly avoided or reduced in Jain discipline:

• Onion
• Garlic
• Very spicy food
• Very oily / fried food
• Excessively sweet food
• Stale or heavy food
• Intoxicants like alcohol

These are believed to increase rajas-like restlessness, making the mind more agitated and less controlled.

For a Jain way of life, the best support is:

• simple sattvic-style food
• moderation
• fasting or restraint
• control of senses
• meditation and self-discipline

If you want, I can also give a Jain list of foods that help reduce kāma and increase brahmacharya.
