Dietary restrictions refer to specific limitations or guidelines on the types of foods or beverages that individuals are advised or required to avoid or limit in their diet. These restrictions are often based on factors such as allergies, intolerances, medical conditions, religious beliefs, cultural practices, or personal preferences. Common examples of dietary restrictions include gluten-free diets for individuals with celiac disease, lactose-free diets for those with lactose intolerance, and vegan diets for individuals who choose to avoid animal products. Adhering to dietary restrictions can be crucial for managing medical conditions, promoting overall health, and respecting cultural or religious beliefs.
