Kashrut (also kashruth or kashrus, כַּשְרוּת) refers to Jewish ietary laws. Food in accord with halakha (Jewish law) is termed kosher in English, from the Hebrew term kashér, meaning "fit" (in this context, fit for consumption by Jews according to traditional Jewish law). Jews who keep kashrut may not consume non-kosher food, but there are no restrictions on non-dietary use of non-kosher products, for example, injection of insulin of porcine origin.
