What are the juristic rules related to foods and drinks in Islamic jurisprudence?

The basic principle concerning food is permissibility, unless there is a textual proof of its prohibition, such as carrion, blood, intoxicants, pork, and anything harmful. This is based on the Almighty's saying: "He has only forbidden to you carrion, blood, the flesh of swine, and that which has been dedicated to other than Allah," and the hadith: "There should be no harm or reciprocating harm," and "Every intoxicant is forbidden."
