Proper nutrition is a critical component in supporting the overall health and development of individuals with autism spectrum disorder (ASD) who experience eating difficulties associated with their autistic traits. Evidence regarding the prevalence, origins, and consequences of eating issues related to ASD is largely derived from studies on autistic children, while information pertaining to adults remains scarce. It is therefore essential to critically review existing research focusing on autistic adults to draw robust conclusions and identify clear research gaps. A computer-aided search in PubMed, Science Direct, Scopus, and Web of Science databases spanning the years 2013–2024 using the search terms covering ASD/Autism, Adult, Nutrition/Nutritional Status, and Diet yielded 43 full-text articles. In our literature review, we explored three critical aspects of nutrition in adults with ASD: their food preferences and sensory processing patterns, studies on nutritional status, and whether dietary and nutritional interventions have improved their adherence to healthier diets. Autistic adults appear to select food based on sensory perceptions. This selection pattern can affect their nutritional status, with a tendency toward overweight and nutritional deficiencies. The most promising intervention strategies incorporate sensory adaptation and structured meal planning. Further research should apply rigorous methodologies that account for this population’s specific characteristics.

Background/Objectives: Dysphagia represents a significant global health concern with particularly high prevalence in specific clinical conditions, yet educational gaps persist among healthcare professionals and caregivers. This observational, cross-sectional quantitative study aimed to provide a comprehensive overview of the current self-perceived knowledge and learning needs among stakeholders involved in dysphagia management. Methods: An international online survey was conducted in five European countries (Greece, Italy, Lithuania, Spain, and Turkey) with 463 participants: 297 professionals (healthcare and non-health specialists, educators, students) and 166 non-professionals (patients, family members, caregivers, interested individuals). Two structured questionnaires explored self-perceived knowledge, learning needs, relevancy of thematic areas, and preferred learning methods. Chi-square and Fisher’s exact tests were used for statistical comparisons. Results: Professionals reported higher self-perceived knowledge than non-professionals (p < 0.001), yet both groups expressed comparable needs for further education. Priority learning areas varied by respondent profile: “Identification & Treatment” was prioritized by both speech-language pathologists and healthcare specialists, as well as by non-professionals, while dietitian-nutritionists focused on “Diet & Nutrition” and “Food Preparation”. Short-duration courses and visual, hands-on learning tools were preferred across groups. Conclusions: This study highlights a broad demand for dysphagia education among professionals and non-professionals. Tailored, technology-enhanced learning programs could bridge existing knowledge gaps, strengthen multidisciplinary collaboration, and support better daily management of dysphagia.

Bread by-product and maize silage as substrates for Tenebrio molitor larvae were studied in four isonitrogenous diets: a control substrate (CTL) made of wheat grain, wheat bran, and soybean meal and three diets where wheat grain and wheat bran were partly substituted with bread by-product (BBP) or with this and either a low (MSL) or high (MSH) proportion of maize silage (170 or 310 g/kg, respectively). Larval weight was weekly monitored, and the chemical composition of larvae and residual substrates was analyzed at the end of the experiment. Larvae fed CTL and BBP grew more than those fed MSL and MSH (p < 0.001). Feed intake was greatest for BBP (p < 0.001), and consequently, feed-to-gain ratio (F:G) was better for larvae fed CTL than BBP, and better for BBP than MSL and MSH (p < 0.001). Besides, total production of crude protein and ether extract were greater for CTL and BBP than for MSH and MSL (p < 0.001). The inclusion of bread by-product in the substrate did not affect growth performance, whereas diets including maize silage impaired larval growth, substrate intake, and F:G. Both by-products can be advantageously used for feeding T. molitor larvae, but the impairments in growth performance should be considered to optimize production costs.
