The evidence in Spanish about how to measure food intake in Children scarcely shows that some instruments fail to meet the criterion commonly used to design valid and reliable questionnaires. In specific cases these basic psychometric properties are not reported or even the Cronbach's alpha index is lower than the measurement literature indicates. Regardless this measurement problem, a common characteristic is that only permits obtain data about consumption frequency. To obtain information about how the foods that are consumed are perceived is needed. In this article, some of the main findings about the most common instruments to measure food intake are reviewed. The purpose is to show findings in advance to get a reliable and valid instrument in Mexico to measure frequency of food intake and food perception of those. The hypothesis is that, food perceived as healthy would be consumed more frequently than those perceived as unhealthy. To probe the good of fit index structural equation models are proposed as well as another index of reliability, Omega. An instrument with this standard will allow generate more scientific evidence to struggle epidemic problems like obesity, eating disorders such as anorexia nervosa.
