Abstract
The scientific literacy related to nutrition, exercise and health plays a crucial role in making everyday decisions. Therefore, this paper describes an educational proposal based on continuous evaluation to fill the gaps related to the presence of alternative ideas in students about those contents.

This promotes the development of a critical scientific thinking in the current consumer society.
