Dietary practice in Buddhism varies widely across traditions and cultures. While many Buddhists choose vegetarianism to express compassion for all living beings, there is no universal rule that applies to everyone. Some Buddhists do eat animal products or meat, especially in communities where meat is common or where meat offerings are given to monks and nuns as alms. Monastic rules about meat also differ by tradition—in some places meat is avoided, in others it may be permitted under certain conditions. Fasting practices are not fixed to Sundays for all Buddhists; fasting or abstaining from meals at certain times occurs on specific days in some traditions but is not a universal requirement. So the statement that best fits the range of practices is that some Buddhists are vegetarians and some eat animal products.
