The term "special dietary requirements" refers to specific food restrictions or preferences that an individual may have due to medical, religious, cultural, or personal reasons. These requirements can include avoiding certain ingredients such as gluten, dairy, or nuts; following a particular diet like vegan or keto; or adhering to certain beliefs that dictate what foods are considered acceptable for consumption. When dining out or ordering meals, individuals with special dietary requirements need to ensure that their needs are accommodated by the establishment in order to maintain their health and well-being.
