Correlates of Feeding Difficulties Among Children with Autism Spectrum Disorder: A Systematic Review

Improving Meal Acceptance of Individuals With Autism Spectrum Disorder (AUT-MENU Project): Protocol for a Bicentric Intervention Study

BACKGROUND

Individuals with autism spectrum disorder (ASD) often exhibit low dietary diversity due to food selectivity, leading to various forms of malnutrition, such as obesity or micronutrient deficiencies.

OBJECTIVE

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 food selectivity.

METHODS

The study is a bicentric intervention conducted in 3 care centers (Pavia and Milan) and 1 secondary school (Rome), involving approximately 200 participants 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 individuals with ASD, 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 postcourse knowledge questionnaire to assess its effectiveness.

RESULTS

Due to different timelines depending on the centers and schools involved, participant enrollment and data collection will take place at different times between Pavia, Milan, and Rome. In September 2024, enrollment was held in the Pavia and Milan care centers for a total of 74 participants enrolled. In Rome, the enrollment phase has not yet started; activities are expected to be carried out similar to those in Pavia and Milan.

CONCLUSIONS

The AUT-MENU study is expected to yield significant insights and improvements in meal acceptance among individuals with ASD, particularly through the introduction of targeted menus in collective catering settings both in care centers and schools.

Eating disorders in children under 4 years of age with autism spectrum disorder: Description and determinants: Eating disorders in children with autism spectrum disorder

BACKGROUND

Eating disorders in children with autism spectrum disorder (ASD) are multifactorial and complex, and impair their quality of life. The link between eating difficulties and ASD is still controversial, and few studies have focused on very young children with ASD.

OBJECTIVES

Our objectives were: 1) to characterize the eating disorders of ASD children under 4 years; 2) to study the links between these eating disorders and the characteristics of the child (symptoms and severity of ASD, level of development).

METHODS

33 ASD children (18 months to 4 years) were included. Their developmental level was assessed by the Brunet-Lézine Revised test (BL-R) and characteristics of ASD by the Autism Diagnosis Interview-Revised (ADI-R). We used a new questionnaire on eating disorders of children between 9 months and 6 years of age that covered 4 dimensions: eating behavior, oro-motor skills, oral and bodily sensory characteristics, and parental impacts and strategies.

RESULTS

70 % of parents declared eating disorders in their child, with an early frequent onset beyond 12 months of age. These disorders caused significant parental suffering and worries about the future in two-thirds of parents, and more than half of the parents implemented strategies to handle them. We found two striking results: 1) No statistical link was observed between the severity of an eating disorder and the severity of ASD symptoms or the child's developmental level; 2) Children with better communication and socialization levels had more eating disorders.

CONCLUSION

These results show that eating disorders in our population are probably linked with the relational nature of the act of eating.

Feeding Behaviors in Infants and Toddlers Later Diagnosed with Autism Spectrum Disorder: A Systematic Review

Children with autism spectrum disorder (ASD) are five times more likely to have feeding difficulties than neurotypical peers, although the majority of evidence describes feeding difficulty in children age 2 years and older. The purpose of this study is to systematically review the literature on feeding characteristics of children age 0-24 months who were later diagnosed with ASD with an emphasis on the measurement tools used to assess these feeding behaviors. We conducted a systematic review of the literature using PRISMA guidelines. Using selected keywords, a search was conducted using PubMed, PsycINFO, and CINAHL databases for relevant articles to identify feeding characteristics in infants and toddlers (age 0-24 months) later diagnosed with ASD. Sixteen studies were selected for this review by two independent reviewers. Among the selected studies, feeding difficulties were reported in all infant oral feeding modalities (breastfeeding, bottle feeding, and complementary feeding) by infants later diagnosed with ASD. However, the evidence was conflicting among studies regarding feeding characteristics, such as sucking differences while breastfeeding, use of the spoon with feedings, and preference of solid food texture, that presented in infants later diagnosed with ASD. A lack of consistent measurement of feeding behaviors in infants later diagnosed with ASD contributes to the difficulty in comparison across studies. Future research should focus on developing targeted, validated instruments for measuring feeding difficulty in this population with emphasis on breastfeeding and bottle feeding difficulty.

The Increasing Prevalence of Autism Spectrum Disorder in the U.S. and Its Implications for Pediatric Micronutrient Status: A Narrative Review of Case Reports and Series

INTRODUCTION

Micronutrient deficiencies are considered uncommon in the United States. However, children with autism spectrum disorder (ASD) are at higher risk due to food selectivity and restrictive eating patterns. The prevalence of ASD in the U.S. has quadrupled over the past two decades, amplifying the need to address nutritional gaps in this population.

OBJECTIVE

This narrative review examines the prevalence and clinical impact of underreported micronutrient deficiencies beyond vitamin C in children with ASD using case reports and series.

METHODS

Case reports and case series reporting micronutrient deficiencies in children with ASD published from 2014 to 2025 were identified through PubMed and ScienceDirect using search terms "autism and deficiency" and "autism and vitamin A, K, magnesium, iron deficiency". Eligible cases included children aged 2-18 years with ASD and laboratory-confirmed micronutrient deficiencies.

RESULTS

A total of 44 cases from 27 articles were analyzed. Frequently reported deficiencies were vitamin D (25.0%), vitamin A (24.8%), B-vitamins (18.0%), calcium (10.8%), and iron (9.6%). Less common deficiencies included iodine, zinc, vitamin E, etc. Diseases such as xerophthalmia, rickets, pellagra, and goiter were reported. Co-occurring deficiencies were present in 70% of cases, and all cases reported food selectivity, with deficiencies occurring despite normal growth parameters in some children.

CONCLUSIONS

Based on cases reviewed, children with ASD are at high risk for micronutrient deficiencies, despite meeting normal growth parameters. Further research is needed to develop a standardized nutrition assessment, but combining anthropometric, biochemical, and dietary assessments can aid in early intervention and prevent complications.

Caregiver perspectives regarding the impact of feeding difficulties on mealtime participation for primary school-aged autistic children and their families

PURPOSE

Although up to 89% of autistic children experience feeding difficulties, little is known about the impact of these difficulties on mealtime participation. The aim of this study was to explore the impact of feeding difficulties on the mealtime participation of autistic children and their families based on caregiver experiences.

METHOD

Participants were 78 caregivers who completed online surveys for 80 children (5-12 years) with a formal diagnosis of Autism Spectrum Disorder (ASD). The online survey contained eight open-ended questions exploring how children participated in mealtimes at home, in the community, at celebrations, on holidays, and at school; as well as exploring cultural influences on mealtimes.

RESULT

Using thematic analysis, three themes were identified: 1) Participation at home, emphasised the individualised nature of experiences and impacts for children and families, while 2) participation in the community, highlighted the range of contexts in which children and families experience challenges. 3) Influence and experience, accounted for cultural and social factors that mediated the child and family's impacts and experience, including a lack of understanding in the community.

CONCLUSION

The findings highlight that autistic children with feeding difficulties and their families may experience a range of mealtime participation challenges. Caregivers also reported feelings of failure, stress, and judgement; some of which stemmed from interactions with extended family, friends, school, and society which increased their difficulties when navigating mealtime participation. Addressing the challenges requires a strengths-based approach including creating inclusive and accessible community environments that accommodate diverse feeding preferences and support the well-being of neurodivergent children and their families.

Comparing eating and mealtime experiences in families of children with autism, attention deficit hyperactivity disorder and dual diagnosis

LAY ABSTRACT

Children with neurodevelopmental conditions like autism and attention deficit hyperactivity disorder may experience eating difficulties and related health issues later in life. Sharing family meals can help prevent these issues developing, but most studies have looked at families with neurotypical children. Our goal was to learn more about how families of children with autism, attention deficit hyperactivity disorder and both conditions (autism + attention deficit hyperactivity disorder) experience mealtimes. We developed an online survey asking caregivers about their child's eating, mealtime experience and if they experienced stress. We tested it with nine caregivers and made improvements based on their feedback before recruiting 351 caregivers to complete the main survey. We found that families of children with neurodevelopmental conditions experienced greater food fussiness, emotional undereating, 'problematic' child mealtime behaviours, dietary concerns, higher stress for caregivers and spouses and less frequent conventionally structured mealtimes compared to those without these conditions. Families of children with attention deficit hyperactivity disorder and autism + attention deficit hyperactivity disorder reported greater appetite, 'problematic' mealtime behaviours and increased stress for caregivers and spouses compared to families of children with autism. Meanwhile, families of children with autism and autism + attention deficit hyperactivity disorder reported less enjoyment of food and less structured mealtimes compared to those with attention deficit hyperactivity disorder. Our findings highlight that families of children with neurodevelopmental conditions, particularly those with autism + attention deficit hyperactivity disorder, have different mealtime experiences and eating behaviours compared to those with neurotypical children. These families may benefit from support at mealtimes. Learning why people do or do not participate in shared family meals will be crucial to developing improved mealtime support in the future.

Unraveling the Connections: Eating Issues, Microbiome, and Gastrointestinal Symptoms in Autism Spectrum Disorder

Autism spectrum disorder (ASD) is a neurodevelopmental condition characterized by challenges in social communication, restricted interests, and repetitive behaviors. It is also associated with a high prevalence of eating disorders, gastrointestinal (GI) symptoms, and alterations in gut microbiota composition. One of the most pressing concerns is food selectivity. Various eating disorders, such as food neophobia, avoidant/restrictive food intake disorder (ARFID), specific dietary patterns, and poor-quality diets, are commonly observed in this population, often leading to nutrient deficiencies. Additionally, gastrointestinal problems in children with ASD are linked to imbalances in gut microbiota and immune system dysregulation. The aim of this narrative review is to identify previous associations between the gut-brain axis and gastrointestinal problems in ASD. We discuss the impact of the "microbiome-gut-brain axis", a bidirectional connection between gut microbiota and brain function, on the development and symptoms of ASD. In gastrointestinal problems associated with ASD, a 'vicious cycle' may play a significant role: ASD symptoms contribute to the prevalence of ARFID, which in turn leads to microbiota degradation, ultimately worsening ASD symptoms. Current data suggest a link between gastrointestinal problems in ASD and the microbiota, but the amount of evidence is limited. Further research is needed, targeting the correlation of a patient's microbiota status, dietary habits, and disease course.

Does food selectivity drive differences in dietary resemblance between children with intellectual disabilities and typical development?

Although children's dietary intake often resembles that of their parents', dietary resemblance has not been examined among children with intellectual disabilities (ID), where food selectivity is a common parental concern. We compared dietary resemblance in children with typical development (TD), ID, and ID and co-occurring autism (ID + A) in parent-child dyads, and examined whether child food selectivity mediated between-group differences. Dietary data from parents and their children (3-8 years, male = 61.8%, TD = 52.9%, ID = 18.6%, ID + A = 28.4%) were analyzed as mother-child (n = 100) and father-child (n = 70) dyads. Dietary resemblance was operationalized as the proportion of foods that were reported as eaten/not eaten by both parent and child in parent-completed Food Frequency Questionnaires. Food refusal rate was used to capture food selectivity (total foods children would not eat/total foods offered). Among mother-child dyads, dietary resemblance did not differ between children with ID compared to TD (P = 0.243). Among father-child dyads, dietary resemblance was 10% lower in children with ID than TD (66.4% vs. 74.1%, P = 0.032), and the difference was partially explained (mediated) by food refusal. Among mother-child dyads, dietary resemblance was 19% lower among children with ID + A than TD (61.5% vs. 75.6%, P = 0.001), and the difference was completely explained by food refusal. Among father-child dyads, dietary resemblance was 22% lower among children with ID + A than TD (57.9% vs. 74.1%, P < 0.001), and the difference was completely explained by food refusal. Subanalyses by food groups produced similar results. Compared to TD children, dietary resemblance was lower in children with ID + A, but not children with ID, and differences were explained by food selectivity. Our findings suggest parents of children with ID + A may have less influence over their child's dietary intake than parents of children with ID or TD.

Diet, growth, nutritional status and predictors of severity of feeding difficulties in autistic children with co-occurring pediatric feeding disorder

BACKGROUND

Feeding difficulties are commonly reported in autistic children. However, there is limited data on the presentation, severity, and impact of feeding difficulties in autistic children in Asia.

AIMS

To describe the dietary patterns, growth and nutritional status of autistic children with pediatric feeding disorder (PFD), and identify factors associated with more severe feeding difficulties.

STUDY DESIGN

A retrospective review of electronic medical records.

SUBJECTS

Autistic children (aged between 0 and 18 years) with PFD, who attended a multidisciplinary feeding clinic between August 2013 and December 2022.

OUTCOME MEASURES

The children's parents provided a 3-day food diary, which was verified by the dietitian and analyzed for their nutritional content using Foodworks 10 Professional. Food selectivity was classified as mild, moderate or severe, based on the number of food groups accepted and the absolute number of foods accepted in each group. Information regarding demographics, height, weight, medical information, developmental history (autism diagnosis, cognition, adaptive skills) and relevant nutritional bloodwork were collected. Parents also completed two validated questionnaires (the Behavioral Pediatrics Feeding Assessment Scale (BPFAS), which assessed childhood mealtime behaviors; and the Caregiver Feeding Style Questionnaire (CFSQ), which determined caregiver/ parental feeding styles). Factors associated with higher BPFAS total frequency scores (TFS) (representing more severe feeding difficulties) and food selectivity were analyzed.

RESULTS

There were a total of 98 patients (82 males), with mean ± SD (range) age of 59.2 ± 27.5 (17-169) months. They had mild (19.4 %), moderate (22.4 %) and severe (58.2 %) food selectivity, respectively. While the majority had normal weight (84.7 %) and height (88.8 %) for age, 69.4 % had diets deficient in calories, macronutrients or micronutrients (iron, calcium). Comparison between groups according to parental feeding style found that there was a significant difference in BFPAS TFS between different parental feeding styles (p < 0.001). Post-hoc testing revealed that parents who reported an authoritarian parental feeding style on the CFSQ were significantly more likely to report higher frequencies of difficult feeding behaviors on the BPFAS (98.3 ± 15.8), while an uninvolved parental feeding style was associated with the lowest BPFAS TFS (80.9 ± 11.0), Bonferroni-adjusted p < 0.001; indulgent (p = 0.012) and authoritative (p = 0.096). Intellectual impairment and Malay ethnicity were associated with more severe food selectivity [adjusted odds ratio 123.7 (95 % CI 3.09-4945.4, p = 0.01) and 38.0 (95 % CI 1.35-1074.18, p = 0.03)], respectively.

CONCLUSIONS

In this retrospective cohort, autistic children with PFD were at significant nutritional risk despite demonstrating normal growth patterns, with specific patient profiles being associated with more severe feeding difficulties.

Exploring Dietary Interventions in Autism Spectrum Disorder

Autism spectrum disorder (ASD) involves social communication difficulties and repetitive behaviors, and it has a growing prevalence worldwide. Symptoms include cognitive impairments, gastrointestinal (GI) issues, feeding difficulties, and psychological problems. A significant concern in ASD is food selectivity, leading to nutrient deficiencies. Common GI issues in ASD, such as constipation and irritable bowel syndrome, stem from abnormal gut flora and immune system dysregulation. Sensory sensitivities and behavioral challenges exacerbate these problems, correlating with neurological symptom severity. Children with ASD also exhibit higher oxidative stress due to low antioxidant levels like glutathione. Therapeutic diets, including ketogenic, high-antioxidant, gluten-free and casein-free, and probiotic-rich diets, show potential in managing ASD symptoms like behavior, communication, GI issues, and oxidative stress, though the evidence is limited. Various studies have focused on different populations, but there is increasing concern about the impact among children. This review aims to highlight the food preferences of the ASD population, analyze the effect of the physicochemical and nutritional properties of foods on the selectivity in its consumption, GI problems, and antioxidant deficiencies in individuals with ASD, and evaluate the effectiveness of therapeutic diets, including diets rich in antioxidants, gluten-free and casein-free, ketogenic and essential fatty acids, and probiotic-rich diets in managing these challenges.

The characterization of feeding challenges in autistic children

LAY ABSTRACT

Feeding challenges are common for autistic children. Currently, research and intervention for feeding challenges focuses on single factors (e.g. behavior or sensory). Research is needed to understand the complexity of feeding challenges. This study provides a comprehensive description of feeding challenges. Furthermore, this study identifies what factors predict the severity and type of feeding challenges experienced by autistic children. Using the Survey for Characterization of Feeding Challenges in Autistic Children-United States, 427 caregivers of autistic children provided information about their child's feeding challenges. Children were between the ages of 2 and 12 with an average age of 8.42 years. Children in the study had a wide variety of feeding difficulties including challenges in early childhood, sensory challenges, difficulty with family mealtime, and variable self-help skills. On average children's feeding challenges were present prior to their autism diagnosis. We found that children who had early feeding challenges had more severe feeding challenges in later childhood. Also, specific early feeding challenges predicted the types of feeding challenges children would have later in childhood. For example, children who had difficulty transitioning to table foods and who continued to restrict their diet over time were more likely to have sensory-based feeding challenges. Results from this study show how feeding challenges present in a wide variety of ways for autistic children. The findings also highlight the importance of screening for feeding challenges in early childhood and collaborating with families to understand individualized feeding challenge experiences. These results could be used to inform evaluation and intervention for feeding.

Autistic traits and eating behaviors in Chinese preschoolers: Role of sensory profiles and home environment

OBJECTIVE

This study aims to 1) explore the association between autistic traits and eating behaviors in Chinese preschoolers; 2) explore the mediating role of sensory processing patterns on the relation of autistic traits and eating-related behaviors; and 3) examine home nurturing environment as a moderator between autistic traits and eating-related behaviors. We hypothesize that there is a significant association between autistic traits and eating behaviors, which is mediated by sensory processing patterns and moderated by the home nurturing environment.

METHOD

509 children aged 3-4 years participated in this cross-sectional research. They were assessed using the Social Responsiveness Scale-Second Edition (SRS-2) for autistic traits, the Chinese Preschoolers' Eating Behavior Questionnaire (CPEBQ) for eating-related behaviors, the Short Sensory Profile-Second Edition (SSP-2) for sensory processing patterns, and the Children Home Nurture Environment Questionnaire (CHNEQ) for home nurturing environment. Mediation regression analyses were used to examine the role of sensory processing patterns, while moderation analyses to examine the role of home nurturing environment.

RESULTS

We observed a positive association between autistic traits and eating behavior problems among typically developed children. Sensory processing patterns significantly mediated the impact of autistic traits on children's eating-related behaviors and home nurturing environment also moderated this relationship.

DISCUSSION

Our research suggests that Chinese preschoolers with higher autistic traits may face more eating challenges when they possess more heightened sensory processing patterns, while living in supportive home environments helps to improve their eating behaviors. These findings contribute to the understanding of how and to what extent eating problems are influenced by autistic traits, and they offer insight into the alleviation of eating problems from the perspectives of sensory patterns and family nurturing environments.

Autistic Children/Adolescents Have Lower Adherence to the Mediterranean Diet and Higher Salivary IL-6 Concentration: Potential Diet-Inflammation Links?

BACKGROUND

Autism spectrum disorder (ASD) is one of the most prevalent neurodevelopmental disorders. Many patients with ASD often show behavioral problems at mealtimes, including food selectivity and atypical feeding behaviors. The Mediterranean diet (MD) has a beneficial effect on mental health for the general population across different ages. There is evidence that good adherence to the MD is effective in reducing peripheral inflammatory markers, such as the cytokine interleukin-6 (IL-6). The present study was designed to evaluate adherence to the MD in children with ASD using age- and sex-matched, typically developing individuals (TDs) as a control group and to determine whether differences in adherence to the MD are associated with salivary IL-6 and IL-6 receptor concentration.

METHODS

Twenty children and adolescents with ASD (mean age 9.95 ± 0.65 years) and twenty TDs (mean age: 9.85 ± 0.59 years) participated in this study (N = 16 males and N = 4 females in each group). Participants with ASD were enrolled in a psychiatric consultation in Valencia (Spain), and TDs were recruited from two public schools in Valencia. The parents of both ASD and TD groups answered the items in a validated Mediterranean Diet Quality Index for children and adolescents (KIDMED) questionnaire on their children's adherence to the MD.

RESULTS

The mean adherence to MD score was significantly lower in the ASD group (9.10 ± 0.42) (range 6-12) than in the TD group (10.35 ± 0.31) (range 8-12) (p = 0.02, Mann-Whitney U test). There was no statistically significant association between adherence to the MD and age or sex in both groups, but there was a significant correlation between the total KIDMED score and body mass index (BMI) in the ASD group. Regarding the concentration of Il-6 and the Il-6 receptor in saliva samples, there were no significant differences between the two groups; however, linear regression analysis by group revealed significant associations between the adherence to MD score and the concentration of IL-6 and its receptor in saliva in the ASD group (p = 0.003, OR = 0.68, 95% CI 0.007 to -0.02; p = 0.009, OR = -0.64, 95% CI -0.01 to -0.00). In contrast, no significant associations were observed between the adherence to MD score and the concentration of IL-6 and its receptor in saliva in the TD group.

CONCLUSIONS

Children and adolescents with ASD showed significantly lower adherence to the MD, which can contribute to nutritional deficits described in ASD, and the role of BMI composition (fat versus lean mass) needs to be further investigated in this group. The concentration of IL-6 and its receptor in saliva is associated with adherence to the MD, suggesting a possible link between IL-6 and diet in ASD. Further studies to clarify the associations between IL-6, psychiatric alterations, and diet in ASD are needed.

Sensory sensitivity and intelligence are correlated with nutrient deficiency in children with autism spectrum disorder and intellectual disability

BACKGROUND/OBJECTIVES

Relationship between dietary intake and sensory sensitivity and intelligence in autism spectrum disorder (ASD) is not well described. This study aims to investigate nutrition status in children with ASD and ID and its association with sensory sensitivity and intelligence.

SUBJECTS/METHODS

84 students (34 ASD and 48 ID) in a special education school were recruited. Dietary intakes were evaluated with 3-day food dairy. Sensory sensitivity was measured using short sensory profile (SSP). Wechsler IQ test were performed.

RESULTS

Two out of twenty-four investigated nutrients had an adequate intake rate of over 50%. Four out of ten investigated vitamins had an inadequate intake rate of over 90% and another two over 80%. 75.6% of participants had inadequate energy intake. After adjusting for age, ASD participants had a higher intake of all surveyed nutrients but only the intake of vitamin E and folate were statistically different (p < 0.05) along with a smaller number of inadequate nutrients (p < 0.001). Taste/smell sensitivity, movement sensitivity, underresponsive/seeks sensation, and total sensory sensitivity symptoms severity were slightly higher in ASD group than in ID group (all p < 0.05). After adjusting for IQ and sensory sensitivity score, difference of number of inadequate nutrients between ASD and ID group were not statistically significant (p = 0.193).

CONCLUSIONS

Individuals with ASD had better dietary intake but worse sensory sensitivity compared to those with ID. Sensory sensitivity and intelligence are correlated with nutritional status in individuals with neurodevelopmental disorder.

Parents' perceptions of the impact of the novel coronavirus (COVID-19) on the eating behaviors and routines of children with autism spectrum disorders (ASD)

Background

Restricted interests and repetitive behavior are characteristics of autism spectrum disorder (ASD). The likelihood that persons with ASD will respond adversely to unfamiliar situations is great. The novel coronavirus outbreak has resulted in disruptions to all aspects of routine and behavior. Hence, this study proposed to investigate the impact of the outbreak on the eating behavior and routines of children with ASD in Saudi Arabia through the perceptions of their parents.

Method

A cross-sectional study with a quantitative approach was utilized to obtain data from 150 parents of children with ASD aged ≤18 years in Saudi Arabia. The data collected included demographic data of the parents, the ASD status of the family, impact of COVID-19 to the family, eating behavior of the children with ASD, and daily routines of the children with ASD. Moreover, parents were able to provide comments regarding their children's eating behavior or daily routines.

Results

The study found that changes in the eating behavior of children with ASD were found to differ significantly (p<0.05) based on the number of children with ASD, the age of the children with ASD, the gender of the children with ASD, and the severity of their ASD symptoms. Moreover, changes to dinner-time routines were found to differ significantly (p<0.05) based on the age of the children with ASD. Also, changes to morning routines were found to differ significantly (p<0.05) based on the age of the children with ASD, their gender, and the severity of their ASD symptoms. Additionally, impact of COVID-19 to the family had a significant impact to eating behavior and daily routines of the children with ASD.

Conclusion

This study found that the eating behavior and daily routines of children with ASD in Saudi Arabia have been considerably worsened and changed. The study recommends the collaboration of multidisciplinary teams and parents to modify or design interventions that help to change their eating behavior and routine can be implemented in the home. It also recommends the provision of virtual helplines to aid parents of children with ASD in such cases.

Dietary intake and gastrointestinal symptoms are altered in children with Autism Spectrum Disorder: the relative contribution of autism-linked traits

BACKGROUND

Dietary and gastrointestinal (GI) problems have been frequently reported in autism spectrum disorder (ASD). However, the relative contributions of autism-linked traits to dietary and GI problems in children with ASD are poorly understood. This study firstly compared the dietary intake and GI symptoms between children with ASD and typically developing children (TDC), and then quantified the relative contributions of autism-linked traits to dietary intake, and relative contributions of autism-linked traits and dietary intake to GI symptoms within the ASD group.

METHODS

A sample of 121 children with ASD and 121 age-matched TDC were eligible for this study. The dietary intake indicators included food groups intakes, food variety, and diet quality. The autism-linked traits included ASD symptom severity, restricted repetitive behaviors (RRBs), sensory profiles, mealtime behaviors, and their subtypes. Linear mixed-effects models and mixed-effects logistic regression models were used to estimate the relative contributions.

RESULTS

Children with ASD had poorer diets with fewer vegetables/fruits, less variety of food, a higher degree of inadequate/unbalanced dietary intake, and more severe constipation/total GI symptoms than age-matched TDC. Within the ASD group, compulsive behavior (a subtype of RRBs) and taste/smell sensitivity were the only traits associated with lower vegetables and fruit consumption, respectively. Self-injurious behavior (a subtype of RRBs) was the only contributing trait to less variety of food. Limited variety (a subtype of mealtime behavior problems) and ASD symptom severity were the primary and secondary contributors to inadequate dietary intake, respectively. ASD symptom severity and limited variety were the primary and secondary contributors to unbalanced dietary intake, respectively. Notably, unbalanced dietary intake was a significant independent factor associated with constipation/total GI symptoms, and autism-linked traits manifested no contributions.

CONCLUSIONS

ASD symptom severity and unbalanced diets were the most important contributors to unbalanced dietary intake and GI symptoms, respectively. Our findings highlight that ASD symptom severity and unbalanced diets could provide the largest benefits for the dietary and GI problems of ASD if they were targeted for early detection and optimal treatment.

Self-Restricted Diet in Pediatric Autism Leading to Vitamin A Deficiency and Severe Photophobia

In developed countries, vitamin A deficiency (VAD) remains rare but is a leading cause of global blindness. We describe the case of a 10-year-old girl with autism spectrum disorder (ASD) initially presenting mild VAD symptoms, escalating to severe photophobia and reluctance to leave a darkened room due to a self-restricted diet of fast-food french fries. A timely examination revealed severe VAD and vitamin A supplementation resolved her symptoms in three weeks. This case highlights the challenge of obtaining accurate patient history in ASD, emphasizing the need for routine dietary discussions and micronutrient testing, especially at ages nine and 13 when the United States Department of Agriculture (USDA) recommends increased vitamin A intake. Early intervention can prevent micronutrient deficiencies in pediatric patients, particularly those with ASD.

Investigating the impact of autistic children's feeding difficulties on caregivers

AIM

The aim of this study was to investigate the influence of children's autism characteristics, sensory profiles and feeding difficulties on caregiver-reported impact at mealtimes.

BACKGROUND

Caregivers of children (5-12 years) with a diagnosis of Autism Spectrum Disorder completed an online survey examining (a) demographic characteristics, (b) children's autism characteristics (Social Communication Questionnaire), (c) sensory profiles (Sensory Profile 2-short form), (d) feeding difficulties (Behavioural Paediatrics Feeding Assessment Scale, BPFAS) and (c) caregiver-reported impact of feeding difficulties (Feeding-Swallowing Impact Survey, FS-IS).

RESULTS

Seventy-eight caregivers completed surveys for 80 children. Children with clinically significant feeding difficulties on the BPFAS (n = 55, 68.8%) had higher levels of caregiver-reported impact on daily activities, worry and feeding difficulties compared to children without clinically significant feeding difficulties (FS-IS; U = 257.000, z = -4.471, p < 0.01). Spearman's rank correlation showed a statistically significant, moderate correlation between BPFAS total frequency score and FS-IS Daily activities score, rs (98) = 0.56, p < 0.01, indicating that as the frequency of feeding difficulties increased, the impact of these feeding difficulties on caregivers also increased. Using multiple regression, a model comprising of the three factors was statistically significant (F[1, 78] = 87.75, p < 0.001, adj. R2  = 0.52), with children's frequency of feeding difficulties the strongest predictor of caregiver-reported impact with a moderate effect size (r = 0.49).

CONCLUSION

Autistic children's feeding difficulties had a greater impact on caregivers than autism or sensory profiles, with the frequency of feeding difficulties and the caregiver impact of these feeding difficulties positively correlated. The findings demonstrate that efforts to understand and address feeding difficulties in autistic children must extend beyond the children to include their families.

Eating and Sensory Features of Children With Autism Spectrum Disorder and Their Typically Developing Peers

IMPORTANCE

Impaired sensory processing is associated with eating problems. There seem to be no previous studies that compare those who have autism spectrum disorder (ASD) with eating problems (ASD-W) and those with ASD without eating problems (ASD-WO) with typically developing (TD) groups. Comparisons are expected to provide further knowledge to guide the intervention programs.

OBJECTIVE

To investigate differences among ASD-W, ASD-WO, and TD groups in eating and sensory features; to detect associations between sensory and eating behaviors and any most involved sensory dimensions; and to search for age-related differences in sensory and eating features in ASD.

DESIGN

Nonrandomized comparison study.

SETTING

Questionnaires administered as parent interviews.

PARTICIPANTS

A total of 165 children were recruited: 117 with ASD and 48 TD children.

OUTCOMES AND MEASURES

Standardized questionnaires: the Brief Autism Mealtime Behaviors Inventory for eating problems; the Short Sensory Profile and the Sensory Experience Questionnaire for sensory problems.

RESULTS

The ASD-W group showed generalized, impaired eating behaviors and turned out to be the most impaired with regard to sensory responsiveness. No differences in feeding behaviors were found between the ASD-WO and TD groups. All children with ASD showed sensory hyper- or hyporesponsiveness. Four main sensory dimensions were found to be associated with eating behaviors in ASD. No age differences were found in the eating and sensory behaviors of children with ASD.

CONCLUSIONS AND RELEVANCE

Differing eating and sensory profiles were found between the ASD and TD groups, especially in children with ASD-W. Early eating interventions using sensory stimulations are strongly recommended. What This Article Adds: This study reports novel information derived from the comparisons of children with ASD with eating problems and those with ASD without eating problems with typically developing groups of children.

Avoidant-restrictive food intake disorder and autism: epidemiology, etiology, complications, treatment, and outcome

PURPOSE OF REVIEW

There is considerable overlap between the features of avoidant-restrictive food intake disorder (ARFID) and autism. The purpose of this scoping review is to provide an overview of studies published on ARFID and autism in 2022 and the first half of 2023.

RECENT FINDINGS

ARFID and autism are highly heritable conditions that often co-occur. In a large autism cohort, 21% of participants and 17% of their parents presented with avoidant-restrictive features. Of children diagnosed with ARFID, 8.2-54.8% are autistic. More than half of individuals with ARFID also have other neurodevelopmental, psychiatric, or somatic diagnoses. Anxiety, depression, sleep disorders, and learning difficulties are particularly common co-occurring issues. Various strategies have been developed to support autistic children with feeding difficulties. It appears that their feeding difficulties, particularly sensory sensitivities, food preferences, and mealtime rituals and routines frequently persist into adolescence and adulthood, but research on optimal support for adults and adolescents is still scarce. Untreated ARFID in autistic individuals may lead to serious complications.

SUMMARY

Individuals seeking specialist care for autism, eating disorders, or gender dysphoria should be screened for ARFID. More research is needed on how to support autistic adolescents and adults with features of ARFID.

Factors in Infancy That May Predict Autism Spectrum Disorder

The global increase in the prevalence of ASD (Autism Spectrum Disorder) is of great medical importance, but the reasons for this increase are still unknown. This study sought to identify possible early contributing factors in children who were later diagnosed with ASD. In this retrospective cohort study, postnatal records of 1105 children diagnosed with ASD were analyzed to determine if any signs of ASD could be found in a large database of births and well-baby care programs. We compared the recordings of typically developing children and analyzed the differences statistically. Rapid increases in weight, height, and head circumference during early infancy predict the development of ASD. In addition, low birth weight, older maternal age, and increased weight and height percentiles at six months of age together predict the development of ASD. At two years of age, these four parameters, in addition to impaired motor development, can also predict the development of ASD. These results suggest that the recent increase in ASD prevalence is associated with the "obesity epidemic" and with recommendations of supine sleeping to prevent Sudden Infant Death Syndrome, associated with atypical neural network development in the brain.

Patterns of Food Selectivity among Children with Autism Spectrum Disorder

Autism spectrum disorder (ASD) is a heterogeneous group of neurodevelopmental disorders characterized by food selectivity in a significant portion of the population. The nature of this selectivity remains unclear, with hypotheses suggesting associations with sensory disorders or stereotypical and repetitive patterns of activity and interests. This study aimed to determine the prevalence and nature of food selectivity traits in individuals with ASD compared with the neurotypical population. This study involved 219 participants, with 115 diagnosed with autism and 92 without. Twelve children undergoing diagnosis were excluded from the analyses. The findings revealed that food selectivity traits are more common in individuals with ASD, with differences in preferences mainly involving structure, color, taste, and serving method. Children with ASD had more food selectivity traits than those without, and the intake of certain food characteristics could be altered as they grow. Selectivity occurred for both sensory and stereotypical reasons, but stereotypical features significantly differentiated neurotypical individuals from those with ASD.

Priorities, barriers, and facilitators for nutrition-related care for autistic children: a qualitative study comparing interdisciplinary health professional and parent perspectives

Introduction

Children with autism spectrum disorder often face nutrition-related challenges, such as food selectivity, gastrointestinal issues, overweight and obesity, and inadequate nutrient intake. However, the role of routine nutrition-related screening or care by interdisciplinary health professionals is not well understood. This study aimed to compare the beliefs of health professionals with those of parents of autistic children regarding high-priority nutrition-related challenges, barriers and facilitators to care, and desired education and resources related to nutrition for autistic children.

Participants

Interdisciplinary health professionals (n = 25) (i.e., pediatricians, occupational therapists, speech-language pathologists, board certified behavior analysts, registered dietitians) and parents of autistic children (n = 22).

Methods

The study used semi-structured phone interviews, which were recorded, transcribed, verified, and double-coded using the Framework Method.

Results

Thematic analysis of transcripts revealed that while health professionals and parents of autistic children shared some perspectives on nutrition-related challenges and care, they also had distinct viewpoints. Parents emphasized the importance of addressing food selectivity, behavioral eating challenges, sensory issues, and sleep disturbances affecting appetite. Both groups acknowledged the need for tailored support, access to an interdisciplinary care team, and reasonable expectations. Some health professionals perceived parents as lacking motivation or the ability to make changes. In contrast, many parents felt that health professionals lacked the knowledge and motivation to take nutrition or growth concerns seriously. Health professionals acknowledged that their lack of knowledge or capacity to provide nutrition education or referrals was a common barrier to care, particularly given limited community resources.

Discussion

Health professionals who serve autistic children are motivated to address nutrition-related challenges but lack resources related to nutrition. To promote better health outcomes for autistic children, professionals should identify and support parent motivations around nutrition-related care. Both groups expressed interest in accessing autism-specific resources for education, referral, and screening guidance. Future research could explore the development of healthcare training models that improve the competency of health professionals in providing nutrition care and referral for autistic children.

Dietary recommendations to customize canteen menus according to the nutritional and sensory needs of individuals with autism spectrum disorder

Individuals with autism spectrum disorders (ASD) are often characterized by food-selectivity, food-neophobia and a marked preference for mild flavor, semi-liquid foods with pale colors. Therefore, they adopt a monotonous dietary pattern, and they prefer ultra-processed food, leading to a high risk of developing malnutrition. In Italy, where 75,072 individuals are diagnosed with ASD, center-based services play a crucial role in their daily management. Despite the centrality of nutrition in maintaining a good state of health, even more for vulnerable subjects, no validated protocol at collective catering level has been developed yet. The manuscript presents customized dietary recommendations aimed at managing the meals for individuals with ASD at collective catering service, derived from a non-systematic literature review exploring food behaviors and nutritional needs in individuals with ASD. Simple practical tips for mealtimes, such as eating together, proper seating, lighting, smell control, presenting food in a simple manner and using the same type of tableware at each meal, to meet the needs of individuals with ASD, were described. The proposal could represent a starting point in developing official guidelines aimed at ASD individuals, in collective catering service.Level of Evidence: Level V.

Each systematic review brief summarizes the evidence on a theme related to a systematic review topic. This systematic review brief presents findings from the systematic review on interventions to support participation in basic and instrumental activities of daily living by autistic1 children and adolescents (birth to 18 yr).

Short report: The role of oral hypersensitivity in feeding behaviors of young autistic children

LAY ABSTRACT

Feeding problems are common among autistic children and are linked to negative health consequences. Therefore, understanding feeding problems and factors that influence these behaviors is important for developing supports for children and families. While certain sensory processing patterns are commonly associated with feeding problems, less is known about the link between sensory processing and feeding behaviors in autism, as well as how parent behaviors and feelings during mealtime differ based on child sensory preferences. This research examined two groups of young autistic children who were reported to be picky eaters by their parents: those with and those without oral hypersensitivity. Children with oral hypersensitivity had more difficulty with food acceptance and their parents reported more negative feelings around feeding their child. However, the two groups of children (oral hypersensitive and not) did not differ in their medical/oral motor symptoms, mealtime behavior, or parent use of strategies at mealtimes. This research supports the need for personalized treatment strategies based on the child's sensory preferences to support both the child and parent in managing mealtimes.

Interrelated development of autism spectrum disorder symptoms and eating problems in childhood: a population-based cohort

Eating problems, such as food selectivity or picky eating, are thought to be an epiphenomenon of autism spectrum disorders (ASD). Yet eating problems are also common in the general pediatric population and overlap with ASD symptoms. However, the temporal association between ASD symptoms and eating problems is poorly understood. This study examines the bidirectional association between ASD symptoms and eating problems across child development, and investigates whether these associations differ by child sex. Participants (N = 4,930) were from the population-based Generation R Study. Parents reported their child's ASD symptoms and eating problems using the Child Behavior Checklist at 5 assessments from toddlerhood to adolescence (1.5 to 14 years, 50% girls). A Random Intercept Cross-Lagged Panel Model was used to examine the lagged associations between ASD symptoms and eating problems at the within-person level, controlling for stable, trait-like differences at the between-person level. At the between-person level, there was a strong correlation between ASD symptoms and eating problems (β = .48, 95% CI: 0.38 to 0.57). Controlling for these between-person effects, there was limited evidence for consistent, predictive effects of ASD symptoms and eating problems at the within-person level. Associations did not differ by child sex. Findings suggest that ASD symptoms and eating problems may represent a cluster of traits that are highly stable from early childhood to adolescence, which have a minimal reciprocal effect at the individual-level. Future research could focus on these trait-like qualities to inform the development of supportive, family-focused interventions.

Realist evaluation of a transdisciplinary mealtime management service for autistic children

LAY ABSTRACT

Mealtimes and eating can be difficult for autistic children. A service where different professions work together is required to address the varied and complex mealtime difficulties of autistic children. Little is known about what is needed for such services to be effective. We interviewed six caregivers of autistic children who were engaged in a mealtime service and 10 therapists who are involved in delivering the service to understand their perspectives on the factors that were driving the effectiveness of the mealtime service. We found that different health professionals from different disciplines working together, focusing on adapting intervention to the child and family and managing expectations of the caregiver were important in contributing to outcomes of the mealtime service. The findings of this study can be used to inform the development of more effective interventions and services to support the well-being and development of autistic children.

A case study on the effect of light and colors in the built environment on autistic children's behavior

Background

The importance of strategies and services by caregivers and family members substantially impact the psychological and emotional wellbeing of autistic children. The rapid research developments in clinical and non-clinical methods benefit the features of autistic children. Among various internal and external factors, the influence of the built environment also impacts the characteristics of autistic children. This study investigates primarily the psychological effect of light and colors on the mood and behavior of autistic children to identify the most favorable and preferred indoor lights and color shades.

Methods

A questionnaire survey was conducted at an autism center among autistic children and their parents. This study included autistic children aged between 6 and 16 (45 males, 42 females, mean age 8.7 years, standard deviation 2.3). Eighty-seven participants were involved in the survey to determine the sensory perceptions, intolerance, preferences, and sensitivities of children with an autism spectrum disorder toward colors and lighting. The margin of error at the statistical analysis's 95% confidence level is ± 0.481.

Results

As per this case report, the children have various color preferences and respond differently to different shades. Different hues have varying effects on autistic children, with many neutral tones and mellow shades proven to be autistic-friendly with their calming and soothing effect, while bright, bold, and intense colors are refreshing and stimulating. The stimulus of bright-lighting causes behavioral changes in autistic children prone to light sensitivity.

Conclusion

The insights gained from this interaction with parents and caretakers of autistic children could be helpful for designers to incorporate specific autistic-friendly design elements that make productive interior spaces. A complete understanding of the effect of factors like color and lighting on the learning ability and engagement of autistic children in an indoor environment is essential for designers and clinicians. The main findings of this study could be helpful for a designer and clinicians to address designing an autism-friendly built environment with a color palette and lighting scheme conducive to their wellbeing and to maximize their cognitive functioning.

Case report: Pulmonary hypertensive crisis leading to cardiac arrest during endoscopic evaluation in a 6-year-old boy with autism, severe malnutrition, and undiagnosed scurvy

Pediatric gastroenterologists are often responsible for the evaluation of malnutrition in the setting of selective eating. Endoscopic evaluation for conditions including eosinophilic esophagitis and celiac disease can help to identify and treat mucosal disease contributing to food selectivity. However, undiagnosed micronutrient deficiencies can cause cardiovascular derangements that significantly increase a patient's anesthetic risk. Vitamin C deficiency in particular, alone or in combination with severe malnutrition, is associated with a severe but reversible form of pulmonary arterial hypertension that, while life threatening in the acute phase, may significantly improve within days of starting ascorbic acid replacement therapy. Here we present a case of a 6-year-old boy with autism spectrum disorder (ASD), severe malnutrition, and undiagnosed chronic vitamin C deficiency who developed a pulmonary hypertensive crisis after induction of general anesthesia leading to cardiac arrest during endoscopic evaluation. While the association between food selectivity among youth with neurodevelopmental differences and vitamin C deficiency is well-described, and pulmonary hypertension is a recognized rare complication of scurvy, extant literature has not addressed next steps to improve patient outcomes. Using this case report as a foundation, we discuss specific patient populations to screen and treat for micronutrient deficiencies prior to anesthesia and propose a novel clinical algorithm for pre-anesthesia risk stratification and mitigation in patients specifically at risk for scurvy and associated pulmonary hypertension.

Dietary intake in children on the autism spectrum is altered and linked to differences in autistic traits and sensory processing styles

Diets of children and adolescents on the autism spectrum often differ when compared to their non-autistic peers. Most dietary studies have been limited by small sample sizes and rarely assess the heterogeneity of autism. Addressing this gap, this study compared the anthropometrics, dietary composition, dietary quality, and food variety of 154 Australian children and adolescents on the spectrum and 213 non-autistic children (71 siblings and 142 unrelated controls). Beyond the case-control approach, within-group comparisons assessed the influence of autism clinical presentations and sensory processing styles on body mass index (BMI) and measures of dietary intake among those on the spectrum. In this word first study of diet that included between-group comparisons with non-autistic peers (siblings and an unrelated comparison group) and within-autism group comparisons, we found that children on the spectrum consumed limited variety and lower quality of food and non-autistic siblings also ate comparably higher levels of energy-dense, nutrient poor food, and less diary. This may be due to autistic traits influencing family's diets or shared sensory sensitivities driving dietary intake. Within the autism group, higher autistic traits were associated with lower BMIs and a specific dietary pattern higher in simple carbohydrates and lower in unprocessed protein. Contrastingly, greater sensitivity to sensory stimuli was associated with a healthier diet. Increased age was linked to more varied diets but also diets higher in saturated fats and energy-dense, nutrient poor foods. Overall, this research highlights that potential mediators of dietary intake, such as familial influences, autistic traits, sensory processing styles, age and sex, need to be considered when assessing diet in the autistic population. LAY SUMMARY: In this study of dietary differences linked to autism, children, and teenagers on the spectrum ate fewer different foods and were less likely to eat recommended amounts of fruits and vegetables when compared to non-autistic siblings and unrelated children and teenagers. There were also family differences, in that those on the spectrum and their siblings ate more unhealthy foods and less dairy. Among those on the spectrum, dietary differences were linked to age, sex, autistic traits and sensory processing styles.

Food Selectivity and Its Implications Associated with Gastrointestinal Disorders in Children with Autism Spectrum Disorders

Food selectivity (FS) in children with autism spectrum disorders (ASD) is common, and its impact on a nutritional level is known. However, the etiology of gastrointestinal disorders (GID) related to alterations in the intestinal microbiota in children with ASD remains unclear. This article provides a narrative review of the literature on FS from the last 15 years, and its relationship with GID in children with ASD. Sensory aversion in ASD leads to food elimination, based on consistencies, preferences, and other sensory issues. The restriction of food groups that modulate the gut microbiota, such as fruits and vegetables, as well as the fibers of some cereals, triggers an intestinal dysbiosis with increased abundance in Enterobacteriaceae, Salmonella Escherichia/Shigella, and Clostridium XIVa, which, together with an aberrant immune response and a leaky gut, may trigger GID. It is observed that FS can be the product of previous GID. GID could provide information to generate a hypothesis of the bidirectional relationship between FS and GID. Emphasis is placed on the need for more studies with methodological rigor in selecting children with ASD, the need for homogeneous criteria in the evaluation of GID, and the adequate classification of FS in children with ASD.

Sensory processing and eating behaviours in autism: A systematic review

OBJECTIVES

The aim of this study was to assess the relationship between sensory processing and a broad range of eating behaviours across the lifespan.

METHODS

Five electronic databases of published and unpublished quantitative studies were systematically searched, evaluated for risk of bias and synthesised according to identified eating outcomes.

RESULTS

Across 25 studies, there was consistent evidence of a relationship between sensory processing and a range of eating behaviours. There was early evidence for the particular role of taste/smell sensitivities, as well as hypersensitivities, although future research is needed looking at different sensory patterns and modalities. There was also tentative evidence to suggest this relationship extends across development.

DISCUSSION

Study findings are discussed in relation to implications for sensory-based eating and feeding interventions and the development of eating disorders. Methodological and conceptual limitations are discussed and suggestions for future research are made to address these limitations. A broader investigation of multi-sensory issues and clearly defined eating behaviours, including disordered eating in clinically diagnosed samples, will allow for a more comprehensive and robust understanding of the relationship between sensory processing and eating behaviours in autism.

Feeding and Swallowing Issues in Autism Spectrum Disorders

Children with autism spectrum disorder (ASD) often experience difficulties related to communication and behaviour. However, their feeding issues are most distressing to their families and healthcare professionals as they impact on the children's adaptive function and health. In comparison to typically developing children, those with ASD experience significantly more feeding difficulties. Children with ASD may display distinctive feeding difficulties and atypical feeding behaviours that include picky eating, limited independent feeding, need for increased feeding times, and a highly restrictive food repertoire. Many of these feeding difficulties continue into childhood, persist in adolescence, and even spill over into adulthood. This proves to be a formidable challenge, as feeding is an essential component for healthy nutrition, growth, and development. This article will highlight how particular food items that are eaten and preferred by affected children may be contributing to their exhibited feeding difficulties. Next, it will be shown how the children's restrictive diets supplant more healthy food options. When this is combined with the children's noted reduced physical activity, the consequences are especially serious, as they include not only malnutrition but also give rise to childhood obesity. In sum, it will be demonstrated that feeding difficulties in young children with ASD are not well understood nor managed. The dearth of knowledge about feeding issues in this population affects both assessment choices and, specifically, management practices - aspects that will be elaborated on in this article. Conclusions will include suggested future directions for enhancing and complementing knowledge of these issues for stakeholders.

Ratings of the Effectiveness of Nutraceuticals for Autism Spectrum Disorders: Results of a National Survey

Autism spectrum disorder (ASD) often involves a wide range of co-occurring medical conditions (“comorbidities”) and biochemical abnormalities such as oxidative stress and mitochondrial dysfunction. Nutritional supplements (“Nutraceuticals”) are often used to treat both core ASD symptoms and comorbidities, but some have not yet been formally evaluated in ASD. The potential biological mechanisms of nutraceuticals include correction of micronutrient deficiencies due to a poor diet and support for metabolic processes such as redox regulation, mitochondrial dysfunction and melatonin production. This paper reports on the results of the National Survey on Treatment Effectiveness for Autism, focusing on nutraceuticals. The Survey involved 1286 participants from across the United States. Participants rated the overall perceived benefits and adverse effects of each nutraceutical, and also indicated the specific symptoms changed and adverse effects. From these ratings the top-rated nutraceuticals for each of 24 symptoms are listed. Compared to psychiatric and seizure medications rated through the same Survey, on average nutraceuticals had significantly higher ratings of Overall Benefit (1.59 vs. 1.39, p = 0.01) and significantly lower ratings of Overall Adverse Effects (0.1 vs. 0.9, p < 0.001). Folinic acid and vitamin B12 were two of the top-rated treatments. This study suggests that nutraceuticals may have clinical benefits and favorable adverse effect profiles.

Ketogenic Dietary Therapies in Patients with Autism Spectrum Disorder: Facts or Fads? A Scoping Review and a Proposal for a Shared Protocol

Autism spectrum disorder (ASD) is a neurodevelopmental disorder with increasing incidence. An expanding body of literature is examining connections between ASD and dietary interventions. Existing reports suggest a beneficial effect of ketogenic dietary therapies (KDTs) in improving behavioral symptoms in ASD. In this context, the purpose of this scoping review was to identify and map available evidence in the literature about the feasibility and potential efficacy of KDTs in pediatric patients with ASD and to inform clinical practice in the field. Moreover, based on the resulting data from the literature review, we aimed to provide a shared protocol to develop a personalized KDT intervention in patients with ASD. A comprehensive and structured web-based literature search was performed using PubMed and Scopus and it yielded 203 records. Seven papers were finally selected and included in the review. Data were abstracted by independent coders. High variability was identified in study designs and dietary aspects emerged among selected studies. Results supported the effectiveness of KDTs in promoting behavioral improvements. Clinical recommendations on which patients may benefit most from KDTs implementation and difficulties in dietary adherence were discussed.
