Health officials claim that because the foods and beverages mentioned or consumed on many television programs are extremely low in nutritional value, watching television has a bad influence on the dietary habits of television viewers. The claim by health officials depends on the presupposition that ['television viewers are only interested in the people on television programs who have the same eating and drinking habits as they do', 'seeing some foods and beverages being consumed on, or hearing them mentioned on, television programs increases the likelihood that viewers will consume similar kinds of foods and beverages', 'the eating and drinking habits of people on television programs provide health officials with accurate predictions about the food and beverages that will become popular among television viewers', 'the eating and drinking habits of people on television programs are designed to mirror the eating and drinking habits of television viewers']
