Many Rastas eat limited types of meat in accordance with the dietary Laws of the Old Testament; they do not eat shellfish or pork. Others abstain from all meat and flesh whatsoever, asserting that to touch meat is to touch death [with the exception of fish which can be eaten], and is therefore a violation of the Nazirite oath. However, the prohibition against meat only applies to those who are currently fulfilling a Nazirite vow, for the duration of the vow. Many Rastafari maintain a vegan diet all of the time, with or without the exception of honey.
Usage of alcohol is also generally deemed unhealthy to the Rastafarian way of life, partly because it is seen as a tool of Babylon to confuse people, and partly because placing something that is pickled and fermented within oneself is felt to be much like turning the body (the Temple) into a "cemetery".
In consequence, a rich 'alternative' cuisine has developed in association with Rastafari tenets, eschewing most synthetic additives, and preferring more natural vegetables and fruits such as coconut and mango. This cuisine can be found throughout the Caribbean and in some restaurants throughout the western world.
Some of the Houses or "Mansions" as they have become to be known of the Rastafari culture, such as the Twelve Tribes of Israel, of which Bob Marley was a part, do not specify diet beyond that which to quote Christ "Is not what goes into a man's mouth that defile him, but what come out of it". Wine is seen as a "mocker" and strong drink is "raging", however simple consumption of beer or the very common "Roots Wine" are not systematically a part of Rastafarian culture this way or that. Separating from Jamaican culture, different interpretations on the role of food and drink within what some might call a religion remains up for debate.
