Jainism
Food and fasting

The practice of non-violence towards all living beings has led to Jain culture being vegetarian. Devout Jains practice lacto-vegetarianism, meaning that they eat no eggs, but accept dairy products if there is no violence against animals during their production. Veganism is encouraged if there are concerns about animal welfare. Jain monks, nuns and some followers avoid root vegetables such as potatoes, onions, and garlic because tiny organisms are injured when the plant is pulled up, and because a bulb or tuber's ability to sprout is seen as characteristic of a higher living being. Jain monks and advanced lay people avoid eating after sunset, observing a vow of ratri-bhojana-tyaga-vrata. Monks observe a stricter vow by eating only once a day.
