157 unresolved questions extracted from the limitations and future-work sections of 977 Child Nutrition and Feeding Issues papers in our library. Each links back to the study that raised it.

What the literature leaves open

  • The study is a secondary analysis of data collected from two independent cohorts. The study only examined cross-sectional associations between household chaos and appetitive traits. Longitudinal and experimental studies are needed to clarify temporality and underlying mechanisms. The study primarily included higher-SES families.

    Associations between household chaos and appetitive traits in preschoolers and preadolescents · 2026 · DOI

  • The mechanisms by which household chaos relates to childhood obesity risk are unclear. Prior research has not fully examined the associations between household chaos and appetitive traits in preschoolers and preadolescents.

  • The role of the parenting environment is also theorized as mutually beneficial for both early language and mental health, but the relationship between these three constructs has rarely been studied together.

  • Future research should focus on clarifying its core elements, goals and outcome measures.

  • Future research should focus on standardizing diagnostic criteria and developing culturally sensitive interventions.

  • While these methods are often studied for their nutritional implications, their impact on maternal mental health, particularly generalized anxiety disorder (GAD), remains understudied.

  • Current data suggest a link between gastrointestinal problems in ASD and the microbiota, but the amount of evidence is limited.

  • Background/Objectives: Research on the safety and efficacy of high-dose folinic acid in Chinese children with autism spectrum disorder (ASD) is limited, and the impact of folate metabolism gene polymorphisms on its efficacy remains unclear.

  • Despite growing evidence, the link between B12 and ASD remains inconclusive due to inconsistent findings across studies.

  • The need for dietician and health professional input and support is key, whereas a lack of guidelines acts as a barrier to blended feeding.

  • BACKGROUND: The main cause of growth and development delays remains unknown, but it can occur as an interaction between genetic, environmental, and socio-economic factors.

  • Their intake of fruits and vegetables is inadequate and hence their intake of vitamins and minerals is insufficient, contributing to stunting.

  • While antibiotics are the primary treatment for SIBO, their effectiveness in promoting weight gain among malnourished children remains uncertain.

  • The etiology and mechanisms of autism and autism spectrum disorder (ASD) are not yet fully understood.

  • Previous studies have found a tendency towards food selectivity with food monotony and difficulties with food texture in children with ASD, but studies in this area, especially in Brazil, are still scarce.

  • The review also highlights the need for standardized treatment protocols and further research on the long-term outcomes of these disorders, aiming to enhance therapeutic strategies and family support systems.

  • 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.

    Exploring Dietary Interventions in Autism Spectrum Disorder · 2024 · DOI

  • Investigation of the long-term efficacy and safety of atypical antipsychotics in children with autism spectrum disorder. Further study of emerging therapies, such as microbiota transfer therapy and high-dose folinic acid.

    Medical treatment of autism spectrum disorder in children: Current evidence, controversies, and clinical challenges · 2026 · DOI

  • Limited understanding of the efficacy and safety of medical treatments for autism spectrum disorder in children. Need for more research on emerging therapies and biomarker-driven interventions.

    Medical treatment of autism spectrum disorder in children: Current evidence, controversies, and clinical challenges · 2026 · DOI

  • Future research should focus on developing effective early identification and intervention strategies for eating disorders in childhood. Future research should investigate the role of family and school contexts in the development and prevention of eating disorders.

    Identificação precoce e intervenção dos transtornos alimentares na infância: uma revisão sistematizada do papel da escola e da família · 2026 · DOI

  • There is a need for early identification and intervention strategies for eating disorders in childhood. The existing literature lacks a comprehensive review of the risk factors and early manifestations of eating disorders in childhood.

    Identificação precoce e intervenção dos transtornos alimentares na infância: uma revisão sistematizada do papel da escola e da família · 2026 · DOI

  • Individuals with eating disorders may experience heightened sensitivity to sensory experiences, leading to anxiety and avoidance. The sensory properties of cutlery can be complex and multifaceted, making it challenging to identify the most important characteristics. There is a need for further research on the relationship between cutlery preferences and eating disorder symptoms.

    Exploring sensory aspects of cutlery in neurodivergent-informed eating disorder care · 2026 · DOI

  • The role of nonfood objects, such as cutlery, in shaping eating experiences has been largely overlooked. Prior research has focused primarily on food texture, taste, and olfactory cues, as well as environmental factors. There is a need for further research on the sensory properties of cutlery in eating disorder care.

  • Limited treatment options for ASD. Inconsistent evidence for CAT approaches. Small sample sizes and methodological limitations in prior studies.

    Complementary and Alternative Treatments for Autism Spectrum Disorder: A Comprehensive Review · 2026 · DOI

  • The role of father involvement in complementary feeding practices remains insufficiently synthesized. There is a need to examine the relationship between father involvement and children’s nutritional status.
