What food rituals do Seventh-day Adventists have?

I was raised in the Seventh-day Adventist church. My father was a minister. To answer your question, typically no. Adventists believe that to have a clear mind you must to as healthy as possible and that the body is the temple of God and since meat tends to degrade the health, most Adventists do not eat meat. However, if you are going to eat meat, Adventist believe that the health laws of Leviticus are still binding so that the only meats that a Bible believer can eat are the ones that The Bible defines as being clean.

Clean animals are as follows:

Mammals: Must have a cloven hoof and chew the cud (Leviticus 11:3) Examples of Clean Mammals: Cows and Chickens

Fish: Must have scales and fins (Leviticus 11:9)

Birds: Clean except for listed unclean birds (Leviticus 11:13) (unclean being scavengers like vultures, hawks, eagles, etc.)

Other answers/comments:

Outside of the United States, the number of Adventists that eat meat varies, but is often higher than in the US.
