If you were to follow the advice commercials aired on television, you would end up eating too much fat, sugar and salt. Explain it in an article published in the Journal of the American Dietetic Association, Michael Mink and colleagues at Armstrong Atlantic State University.
According to the authors of the study, the ubiquity of television in America makes it a potential key factor in creating an environment "obesogenic", that promotes obesity. The commercials on TV are in fact a proposal for a diet. Da queste considerazioni nasce l'idea di paragonare il contenuto nutrizionale dei cibi proposti dalla pubblicitĂ con le linee guida sull'alimentazione.
A questo scopo sono state analizzate 84 ore di programmazione mandate in onda in prima serata e il sabato mattina durante l'autunno del 2004. Dal test è emerso che un'alimentazione basata sui cibi offerti dagli spot avrebbe 25 volte il valore di zucchero consigliato, 20 volte quello di grassi e solo il 40% delle porzioni di verdura ottimali, il 32% di latticini e il 27% di frutta. Nel complesso il menu giornaliero risulterebbe troppo ricco in proteine, grassi, grassi saturi, colesterolo e sodio, e povero in carboidrati, fibre, vitamine A, E e D, acido pantotenico, ferro, fosforo, calcio, magnesium, copper and potassium.
In fact, a hypothesis which finds some confirmation is that advertising changes consumer preferences. A study has shown, for example, this appears persuasive promotions aimed at children, especially when they use the most famous cartoon characters. The research was led by Chris Roberts and colleagues at Yale University, and published on the number of Pediatrics, 21 June. It was found that children in the age group 4-6 years are the most delicious cookies, candies and even the carrots when they are printed on the package recognizable characters like Dora, Scooby Doo and Shrek. For example, in the case of biscuits, 55% of children said that those with the character had a better taste, compared with 37% who chose the answer "same taste" and 7% who preferred to those without character. The results for the marshmallows to the fruit were similar, while in the case of carrots showed a less marked preference.
In both cases, the study ends with an appeal to the regulation of advertising of foods with a high-calorie and low nutritional value.
