This is an implementation type II hybrid study with randomisation in cluster, whose objective is to compare two strategies of implementation of the Brazilian cardioprotective diet guidelines in primary health care in two Brazilian cities. All health professionals from the health units (clusters) randomized to the intervention group will receive training on the subject. The health professionals from the health units randomized to the control group will follow the usual activities, receiving only the printed guidelines, as usually done. After 6 months, the prescription rate of the Brazilian cardioprotective diet will be evaluated, as well as the quality of the diet of patients in both groups.

Clusters Inclusion criteria: All Public Primary Care Units from both cities will be included. However, the Health services that encourage health professionals to use the Cardioprotective Food manual before randomization will be excluded.
