“…The most convenient way to distinguish vegetarians is according to the food categories they choose to include in or omit from their diet, including semi-vegetarian/flexitarian (consumes vegetarian most of the time, occasionally meat), pesco-vegetarian (consumes seafood), pollo-vegetarian (consumes poultry), lacto-ovo vegetarian (consumes dairy and eggs), lacto-vegetarian (consumes dairy), ovo-vegetarian (consumes eggs), and vegan (does not consume any animal-based products) ( Beardsworth and Keil, 1991 ; Raphaely and Marinova, 2014 ). Many researchers have proposed that the general reasons for selecting a vegetarian diet are health concerns, ethical reasons, the welfare of animals, concerns about the environment, religious faith, social concerns, weight management, flavor, and abomination toward the sensory properties of meat ( Ruby, 2012 ; Hoffman et al, 2013 ; Cramer et al, 2017 ; Plante et al, 2019 ; Šmugović et al, 2021 ). Whatever the classification basis may be, the vegetarian population has become far more varied and complex than may originally have been conceived.…”
