In Jain tradition, food is commonly classified into four types of āhāra:

1. Khādya — food that is chewed

- Example: roti, rice, fruits, dry snacks

1. Svādya — food that is sucked

- Example: sugarcane, some fruits

1. Lehya — food that is licked

- Example: pickles, chutney, honey-like substances

1. Peya — food that is drunk

- Example: water, milk, juice, soup

Jain scriptures also discuss food from the point of ahiṃsā and purity, such as:

• Sacitta — containing life/bodily vitality, generally avoided
• Acitta — lifeless or properly prepared, acceptable
• Trasa — moving living beings, avoided
• Sthāvara — immobile living beings, also to be carefully avoided in harmful form

In practical Jain dietary conduct, food is judged not only by category, but also by:

• harm to living beings,
• freshness and purity,
• time of preparation,
• and whether it is suitable for vows and practices.

If you want, I can also give the Jain classification of food for lay followers and sadhus separately.
