The primary dietary restriction observed by Muslims is the prohibition of consuming pork and its by-products, as outlined in Islamic dietary laws known as halal. Additionally, the consumption of alcohol is strictly forbidden. Halal refers to what is permissible or lawful in Islam, and foods must meet specific criteria to be considered halal. This includes not only the types of food consumed but also how they are processed and prepared. Many Muslims are also cautious about ensuring that meat comes from animals that have been slaughtered according to Islamic guidelines, known as zabiha.
