\"\"<\/a>Pessoas que exageram na ingest\u00e3o dos chamados junk food<\/em> (alimentos com pouco valor nutritivo, ricos em gordura e a\u00e7\u00facar) tendem a perder o interesse por alimentos de uma dieta equilibrada, segundo um estudo publicado em uma revista cient\u00edfica. Um experimento feito com ratos mostrou que o excesso de junk food<\/em> pode modificar o comportamento alimentar, enfraquecer o autocontrole e levar a pessoa \u00e0 obesidade.<\/p>\n

Os pesquisadores da Escola de Ci\u00eancias M\u00e9dicas da Universidade de New South Wales, coordenados pela especialista em farmacologia Margaret Morris, descobriram que uma dieta pobre em nutrientes provoca mudan\u00e7as duradouras nas \u00e1reas do circuito de recompensa do c\u00e9rebro, respons\u00e1vel pela sensa\u00e7\u00e3o de prazer, e no c\u00f3rtex orbitofrontal, que responde pela tomada de decis\u00f5es.<\/p>\n

Durante o experimento, os pesquisadores ensinaram os ratos a associar \u00e1gua com a\u00e7\u00facar a um som e cereja e uva a outro. Os ratos saud\u00e1veis paravam de responder a est\u00edmulos ligados ao sabor que haviam experimentado em grande quantidade. Este mecanismo inato, difundido em animais, protege contra excessos e \u00e9 respons\u00e1vel por promover uma dieta saud\u00e1vel e equilibrada.<\/p>\n
