I’ll answer your question directly and also bring it back to the Jain viewpoint on food.

First, I’ll request: let’s avoid abusive language for any Dharma or practice. In Jainism, samyam (self‑control) and vinay (respect) in speech are important, even when we dislike something.

1. What is halal?

• Halal is an Islamic term meaning “permitted.”
• In food context, it mainly refers to:

- Meat from animals killed in a specific religious way. - No pork, no alcohol.

• There is intentional killing of animals, so from a Jain viewpoint, halal meat is strongly hiṁsā (violence) and completely unacceptable as āhār.

2. What is kosher?

• Kosher is a Jewish term meaning “fit / proper.”
• In food context, it includes:

- Specific animals allowed and forbidden. - Special slaughter method. - Separation of milk and meat, etc.

• Again, animals are killed for food, so from the Jain view it is also hiṁsā and not allowed.

So:

• Halal and kosher both accept killing animals.
• Jain āhār is based on not killing (or minimizing harm) to any jīva.

3. Why do they “taste” different from Jain āhār?

Taste is:

• Personal habit,
• Tongue conditioning,
• Spices and cooking style.

From Jain Darshan, taste is not the main point. The main point is:

> “How much violence (hiṁsā) to jīvas is involved?”

So:

• Halal / kosher non‑veg:

- Direct, intentional killing of 2‑indriya, 3‑indriya, 4‑indriya animals (and higher) → very heavy karma‑bandh.

• Jain āhār:

- Pure vegetarian, usually no meat, fish, eggs, honey, and mostly no root vegetables, no night‑eating, etc. - Aim = minimum hiṁsā, maximum sattvikta and samyak bhāva.

If someone feels Jain food “tastes bad”, usually:

• They are used to strong刺激 (onion–garlic, meat, alcohol, etc.),
• Simple sattvik food then feels “bland” at first.

But as rāga–dveṣa (likes–dislikes) calm down, many people find:

• Light, ahimsak food actually makes the body and mind much more peaceful and clear.

4. Jain focus: Why Jain āhār is different

Jain food rules come from one main principle: Ahimsā Parmo Dharmaḥ – non‑violence is the highest religion.

So Jain āhār tries to:

1. Avoid killing higher jīvas (animals, birds, fish, etc.).
2. Reduce harm even to small jīvas (e.g., avoiding root vegetables, eating in daylight, filtered water).
3. Keep the mind calm, not over‑excited (so avoiding alcohol, excess spice, etc.).

In summary:

• Halal = Islamic permitted food, includes animal slaughter.
• Kosher = Jewish permitted food, also includes animal slaughter.
• Jain āhār = minimum violence, pure vegetarian, very careful about even tiny lives and mental purity.

So from a Jain standpoint, it’s not about which “tastes like shit”, it’s about which causes less hiṁsā and less karmic bondage.
