The exhibition, titled Small changes to eat better, introduces the hand method as a simple tool for portion control. This technique uses an individual's hand size to estimate the recommended amounts of vegetables, proteins, and carbohydrates for a balanced daily diet.

Visitors can engage with educational displays to build a healthy plate and learn about seasonal foods. The project is supported by the Catalan Public Health Agency and the hospital's own Nutrition and Dietetics Unit to provide science-based dietary advice.
