We live in an era where the transition to online life is a reality. In this context, the communication tactics of all health professions, but also of the dietitian in particular are modified. The dietitian's communication skills are the cornerstone of a successful career. One of the most important things to remember in this area is that communication is not limited to publishing information, that is, simply informing. In this new conext of communication, Social Media (SM) are playing a crucial role. The number of customers getting informed by SM is growing.
SM provide to dietitians a smart way to promote her/his work. Although they have several negative dimensions, they are still a great opportunity for the dietitian to communicate nutritional messages, to correct misconceptions, to speak / communicate directly and quickly with the public. In order to formulate an effective communication policy, it is initially important to identify two parameters:

1. The audience we are addressing (age, geography, interests) and
2. What is our goal. Also, the definition of content, the human-centered approach and the way of interaction define the framework of a successful social media communication policy.
