Dietary food refers to any food that is specifically intended for individuals who follow certain dietary restrictions or preferences. This type of food is usually free from specific ingredients, such as gluten, dairy, soy, nuts, or sugar, and may also be low in calories or high in nutrients. Dietary foods are often marketed towards people with certain dietary needs, such as those who follow a vegan, vegetarian, kosher, halal, or gluten-free diet. The term "dietary" is used to describe the type of food that falls within these specific guidelines and restrictions.
