In Jain teachings, food choices are governed by ahimsa (non-violence) and the goal of reducing harm to all living beings. Milk and dairy are a nuanced topic within this framework.

• What is commonly said: Milk can be a source of nutrition (protein, calcium, energy) and has historically been considered a relatively less harmful animal product compared to meat. Many lay Jains have consumed dairy as part of a lacto-vegetarian diet, especially for children, elders, or those who need extra nourishment. But in modern times, many Jains, especially ascetics, re-evaluate dairy because industrial dairy practices involve animal suffering, calves being separated from mothers, and other harms. So the stance on milk varies by personal vows and community tradition.

• Why some avoid milk (ahimsa emphasis): From a strict ahimsa perspective, any animal product can involve violence or suffering in its production. Many Jain monks and nuns (both Digambara and Śvetāmbara) choose to abstain from milk and all dairy as part of their vow to minimize harm. This reflects a deeper aim to reduce violence to higher-sensed beings and to follow the path of pure non-violence in daily life.

• Practical guidance in Jain thought: If one chooses dairy, the emphasis is on mindful, compassionate choices and striving to minimize harm, while also recognizing health needs. Some Jains supplement or switch to plant-based milks to align with ahimsa more strictly. The key is balancing health, compassion, and the spiritual aim of reducing violence.

In short: cow milk is considered nutritionally beneficial, but its acceptance in Jain practice depends on how one weighs ahimsa and the source of dairy. Different communities and individuals may have different practices, with many ascetics avoiding dairy altogether and many lay practitioners choosing dairy with an awareness of ahimsa and animal welfare.
