RESUMO
Chile has a serious public health problem due to the high prevalence of both unhealthy dietary patterns and mental illnesses. Given that dietary quality is positively associated with the quality of mental health, it is urgent that healthy dietary patterns be promoted among Chileans. The WHO recommends the use of mass media for the dissemination of knowledge about mental health. Since health news affect people's attitudes and health behaviors, this study analyzed the coverage by three Chilean online newspapers with the largest readership regarding the relation between diet and mental health in 2016. A previously constructed corpus of 2551 news items about food was analyzed quantitatively. The results show that the relevance of the topic diet and mental health was low in all three newspapers. The most frequent type of information was on "foods" and not "nutrients" that "benefit"-not that "damage"-mental health. The quality of the news was poor as a narrow range of sources was found. An individual responsibility frame predominated in the information to the detriment of a public health frame.
