Background/Objectives: Individuals with Autism Spectrum Disorder (ASD) often exhibit low dietary diversity due to Food Selectivity (FS), leading to various forms of malnutrition, such as obesity and/or micronutrient deficiencies. The main objective of the AUT-MENU project is to improve meal acceptance among individuals with ASD. A secondary goal is to evaluate the effectiveness of a nutrition education course for parents of enrolled participants to reduce FS. Methods: The study is a bicentric intervention conducted in three care centers (Northern area, Pavia and Milan) and one secondary school (Southern area, Rome), involving individuals with ASD aged 3 to 35 years. The study consists of an observational phase (T0) and an intervention phase (T1). At T0, biographical data, clinical characteristics, and dietary patterns of participants are collected. Based on T0 findings and existing nutritional recommendations for ASD individuals, targeted menus are developed and tested. At T1, the same assessment tools used at T0 will be applied to evaluate intervention effects. Additionally, a nutrition education course for caregivers will be implemented between T0 and T1, with a pre- and post-course knowledge questionnaire to assess its effectiveness. Results: This paper reports the results from the care centers in the Northern Area. Conclusions: Menu adaptations, developed according to individual preferences and nutritional guidelines, did not significantly modify food consumption but were well tolerated, allowing for an improvement in the nutritional profile of meals without reducing acceptability. These findings support the feasibility of implementing tailored menu strategies in collective catering for individuals with ASD.
