What is Feeding Therapy?

Specialised support for food selectivity, oral motor skills, and mealtime challenges.

Evidence Summary

Research on feeding therapy for autism remains limited. Of 43 studies reviewed, most showed limited or moderate evidence quality, with only one study rated as strong. The evidence base includes very few participants overall, making it difficult to draw firm conclusions about effectiveness. While some research suggests potential benefits for eating difficulties, more high-quality studies with larger groups are needed before clearer patterns emerge about who might benefit most.

Unlocking the Link: Exploring the Association Between Food Selectivity and Health Outcome in Autism Spectrum Disorder-A Systematic Review.

Nutrition reviews2026

Conti Maria Vittoria, Breda Chiara, Basilico Sara et al.

Plain-English summary

This review looked at how picky eating affects the health of people with autism. It found that autistic individuals who are very selective about food are more likely to be overweight or obese, have nutritional deficiencies, and experience stomach problems. The picky eating patterns common in autism can lead to not getting enough vitamins and minerals, which affects overall health. However, studies used different ways to measure picky eating, making it hard to compare results.

Eating behaviours of children with ASD: Associations with parental stress, perceived symptom severity, and parenting style in a sample from Türkiye.

Appetite2026

Tekin Serra, Brown Janice, Karadeniz Gülçin

Plain-English summary

Researchers studied 69 Turkish families with autistic children aged 2-9 to understand how parenting stress and styles affect eating behaviours. They found that stress levels and autism severity didn't predict picky eating or how well children knew when they were full. However, strict parenting was linked to children enjoying food less, while overprotective parenting was associated with children enjoying food more. Cultural differences may play a role in these patterns.

"I've got to fix this": Mothers' challenges when experiencing feeding difficulty in their autistic children during infancy.

Research in developmental disabilities2026

Campbell Amy A, Barroso Julie, Weitlauf Amy et al.

Plain-English summary

This study interviewed 24 mothers about feeding problems they had with their babies who were later diagnosed with autism. Mothers faced three main challenges: actual feeding difficulties, emotional stress from these problems, and pressure to feed their baby properly. The researchers found that mothers need much more support during this time, including help from doctors, mental health professionals, and feeding specialists. Early support could reduce the stress and burden on families dealing with feeding challenges.

Unique feeding profiles in children with pediatric feeding disorder and comorbid autism spectrum disorder: a retrospective cohort study.

European journal of pediatrics2026

Galai Tut, Goldberg Yael, Ziv Alma et al.

Plain-English summary

This study looked at feeding problems in young children (0-5 years) with and without autism. Children with both autism and feeding difficulties were more likely to be boys, born by cesarean section, and have parents with less education. Their feeding problems appeared later and were more often related to nutrition rather than social/behavioral issues around eating. Importantly, feeding problems sometimes appeared before autism was diagnosed, suggesting feeding difficulties might be an early sign of autism.

Plain-English summary

This review looks at two brain chemicals (oxytocin and vasopressin) that might help explain why autism and anorexia, despite affecting different genders more often, sometimes occur together. Autism is more common in boys, anorexia in girls, but both involve social difficulties and eating issues. These brain chemicals affect social behavior and eating, and might work differently in males and females.

Children with autism spectrum disorder and alterations in eating behavior: could it be gastroesophageal reflux disease?

Jornal de pediatria2026

de Almeida Christine Audet, Siqueira Eduardo Sampaio, Souto Maior Marcelo do Rego Maciel et al.

Plain-English summary

This study looked at eating problems in 115 autistic children and found that 60% had eating difficulties. Of those with eating problems, almost 90% showed signs of acid reflux (GERD). When doctors examined some children more closely with a camera test, they found inflammation in the throat and stomach in 3 out of 8 children tested. This suggests that some eating problems in autistic children might be caused by medical issues like acid reflux that cause pain or discomfort when eating.

Plain-English summary

This study looked at 110 autistic children aged 3-6 years to see if those with picky eating had different behaviors than those without. Children with picky eating showed more aggressive behaviors and more withdrawn behaviors. This suggests that when helping children with eating difficulties, it's important to also consider their emotional and behavioral needs. Early identification by doctors can help families get support from feeding specialists.

Symptomatic Vitamin and Nutrient Deficiencies of Autism Spectrum Disorder and the Potential for Treatment.

Journal of child neurology2026

McAbee Gary N, Morse Anne Marie

Plain-English summary

Children with autism often have very restricted diets due to food sensitivities, preferences, or digestive issues. This puts them at much higher risk of vitamin and nutrient deficiencies - about 5 times more likely than other children. These deficiencies can affect brain development, behavior, sleep, and physical skills. The warning signs can be hard to spot, but if caught and treated early, the problems are usually reversible. If left untreated, some effects could be permanent.

Plain-English summary

Researchers interviewed 24 mothers about feeding their babies who were later diagnosed with autism. They found that feeding difficulties during the first year of life might be early signs of autism. These included problems with bottle feeding, drinking from cups, and starting solid foods. The feeding challenges seemed related to repetitive behaviors, communication differences, and sensory sensitivities that are common in autism.

Plain-English summary

This study looked at how feeding difficulties affect mealtimes for 80 autistic children aged 5-12. Researchers surveyed parents and found that feeding challenges impact family life both at home and in the community. Parents reported feeling stressed, judged by others, and like they were failing. These feelings often came from interactions with family, friends, schools, and the wider community who didn't understand their child's needs.

Plain-English summary

This review looked at eating problems in autistic children and teens. It found that sensory issues, rigid thinking patterns, and gut-brain communication problems all contribute to feeding difficulties. Autistic children often have very limited food preferences and may develop serious eating disorders. Some become underweight while others become overweight. The research shows that treatment needs to address nutrition, behavior, and emotions together for each individual child.

Matthews Zoe, Pigden-Bennett Donna, Tavassoli Teresa et al.

Plain-English summary

This study looked at mealtime challenges in families with children who have autism, ADHD, or both. Researchers surveyed 351 families and found that mealtimes are much more stressful for families with these conditions. Children were more fussy with food, ate less when upset, and showed more difficult behaviors at meals. Parents experienced higher stress levels. Children with both autism and ADHD had the most challenges. The findings suggest these families need extra support around mealtimes.

Plain-English summary

This study looked at eating problems in young children with autism and other developmental delays. More than half of the children had feeding difficulties, even though most were growing normally. Children who showed more repetitive behaviors and weren't in school yet had more eating problems. This suggests parents and doctors should watch for feeding issues even when children are growing well, especially if the child has strong repetitive behaviors.

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

Appetite2025

Rancaño Katherine M, Curtin Carol, Must Aviva et al.

Plain-English summary

This study looked at how similar children's diets are to their parents' diets. Children with intellectual disability and autism ate much less similarly to their parents (19-22% less) compared to typically developing children. Children with just intellectual disability were mostly similar to their parents, except with fathers. The main reason for these differences was food selectivity - children with autism and intellectual disability refused more foods, which explained why their diets were less like their parents'.

Plain-English summary

This study looked at 503 preschoolers in China to understand how autism-like traits relate to picky eating and food avoidance. Parents filled out questionnaires about their children's social behaviors, sensory sensitivities, and eating habits. The research found that sensory processing differences help explain why some children with autism traits have more feeding difficulties. Children who are over-sensitive to sensory input or who avoid certain sensations tend to have more eating problems, while those with under-responsive sensory systems may actually eat better.

This study looked at eating habits and stomach problems in 121 children with autism compared to children without autism. Children with autism ate fewer fruits and vegetables, had less variety in their diet, and experienced more constipation and stomach issues. The researchers found that certain autism behaviors affected what children ate, but stomach problems were mainly caused by poor diet quality rather than autism behaviors directly. This suggests that improving diet quality could help reduce stomach problems in children with autism.

Plain-English summary

This study looked at feeding problems in 427 autistic children. Most feeding challenges started before the autism diagnosis. Children who had feeding problems early on often had more serious feeding issues as they got older. The type of early feeding problem could predict what kind of challenges they'd have later. For example, kids who struggled moving from baby food to regular food were more likely to have sensory feeding issues. The study shows feeding problems are complex and different for each child.
