History and background

Although Christianiy doesn't have general food prohibitions, there are a few connected to particular denominations.

Catholicism – there are holy days and periods on which devout Catholics will fast. For example, meat is not allowed on Fridays during Lent. And fasting is expected on Good Friday and Ash Wednesday.

Eastern Orthodox Christians – if practicing, there will be weekly fasts that require abstention from alcohol, eggs, dairy, fish, meat and olive oil. There are other fasts that are longer and are more exclusionary in their food choices.

Seventh-Day Adventists – are what’s called lacto-ovo-vegetarians. This means they avoid alcohol, fish, poultry and other meat, but will eat some animal products, such as eggs and dairy.
