Kosher

Certain food items are considered appropriate for the kosher style of life. Most grains, vegetables and fruits are considered kosher. The meat, eggs and milk of certain animals are permitted for consumption, while others are not; however, meat and milk are never combined. Certain laws specify how the animal in question should be prepared and which parts of the animal are most appropriate for consumption. With that in mind, specific foods (such as meat and milk) should not be consumed at the same time. Individuals consuming both items should allow for a stretch of time between each item. Wines and fruit juices must be approved before they can be categorized as kosher.  These beverages can be approved by a rabbi or kashrut supervision agency. 

In order for a restaurant or eating establishment to serve food that is deemed kosher, the establishment must receive certification from a rabbi, rabbinical institution or kashrut supervision agency.  Processed foods must also be certified by one of these institutions in order to be considered kosher.
