From the Jain viewpoint, ahimsa (non-violence) is a core principle. Eating fish involves harming aquatic life, so most Jains avoid fish as part of a strictly vegetarian (ahimsa-based) diet. This applies to both Digambar and Shwetambar traditions, though individual practices can vary slightly by community.

If you’re seeking vitamins and nutrients without fish, good vegetarian options include:

• Leafy greens (spinach, saag, collards) for iron and calcium
• Whole grains, legumes, and fortified cereals for B vitamins and minerals
• Nuts, seeds, and legumes (chia, flax, walnuts, soy) for omega-3s and healthy fats
• Fruits and vegetables rich in vitamins A, C, and other micronutrients
• Algal (seaweed) or algae-based omega-3 supplements as a plant-based alternative to fish oil
• Dairy or fortified plant milks (if dairy or vegan options align with your personal Jain practice)

If you have health concerns or a specific nutritional need, it’s best to consult a Jain teacher or a healthcare professional who understands Jain dietary principles to help tailor a safe vegetarian plan.
