You grab your phone and open TikTok. An influencer points a yogurt at the camera and says it looks healthy, but it's actually an industry trick. A content creator claims intermittent fasting has changed their life. Another thirty-second video makes gluten the big enemy to defeat. You've just watched them, you close the app, sit down at your computer, and open an artificial intelligence tool to prepare a personalized diet for you. We've never received so many messages about what to eat, what to avoid, and how to do it. But, amidst this avalanche of information, distinguishing scientific evidence from digital noise has become an increasingly complex task.This situation is not anecdotal. An analysis by Dublin City University and MyFitnessPal of over 67,000 TikTok videos concluded that only 2.1% of nutrition content adhered to public health and nutrition guidelines. It is in this context that undergraduate and postgraduate nutrition training is being advocated for, mainly within healthcare professions. If the foundation for practice is a degree in Human Nutrition and Dietetics, master's degrees allow for deeper exploration into increasingly complex areas, such as personalized nutrition, sports nutrition, public health, or food and planetary health. In Catalonia, public universities offer various possibilities in these fields.The challenge of myths and screens

In the consultations of dietitians-nutritionists, the impact of social networks and AI has been detected for some time. “I perceive a society with more nutritional information, but also more confusion, where patients tend to react in a polarized way: either they adopt extreme diets, or they are blocked from any change”, summarizes Mar Gassó, dietitian-nutritionist at the BCN Diabetes & Endocrine Institute (IBADE). As she explains, in recent years these habits have even “rradicalized”, and there are people who restrict food groups or are less afraid of miracle diets.

Beyond being a symbol of culture and identity, Catalan cuisine is healthy: balanced, varied, and rooted in the principles of the Mediterranean diet. "It's very complete because it combines vegetables, legumes, grains, fish, meat, and olive oil," explains Mar Gassó, a dietitian and nutritionist at the Barcelona Diabetes & Endocrine Institute (IBADE), to ARA.
