The Autism/Nutrition Connection


Autism Spectrum Disorder (ASD) is an overarching term for a group of complex neurodevelopmental disorders of the brain affecting cognitive development, verbal and nonverbal communication, social interaction, and repetitive behavior. These behaviors are typically addressed in therapies such as Occupational Therapy, Speech Pathology, Physical Therapy, Behavioral Therapy, Social Groups, and many others. These therapies are completely vital to treating ASD, but amidst treating the symptoms, the root cause can often be overlooked. Many times, the root cause of a behavior is completely unknown, possibly stemming from somewhere deep inside the brain. Other times, the root cause can be quite simple.

Brittyn Coleman, MS, RDN/LD speaks about the importance of nutrition in autism spectrum with Dr. Wilson of Wilson Chiropractic. Between food selectivity, nutrient deficiencies, food sensitivities, and gastrointestinal issues, there is so much we can do for those on the autism spectrum through diet.

During a consult, I will take a holistic and comprehensive approach to pinpoint and treat your child's nutrition problems. These can manifest in many different ways such as:

  • Food selectivity or extreme “pickiness”

  • Food aversions to textures, appearance, smells, or temperature

  • Avoidance of entire food groups

  • Frequent constipation and/or diarrhea

  • GI problems

  • Bacterial or yeast overgrowth

  • Present or suspected food intolerances/allergies

  • Poor appetite

  • Difficulty sleeping


  • Poor weight gain, underweight, or failure to thrive

  • Excessive weight gain, overweight, or obesity

  • Poor methylation

  • Eczema or other skin conditions


  • Anemia or other nutrient deficiency

  • Suspected poor nutrient intake

  • Feeding or eating disorders

  • Craving non-food items (pica)

  • Genetic mutations

Read more about the success of nutrition intervention (diet and nutritional supplements versus medication) on autism through a study done by the Autism Research Institute.

(HINT: parents report higher success with nutrition intervention than medication usage).

Can You CURE Autism?

To date, there is no known definitive cure or cause of autism. What I WILL do is provide your child with an individualized nutrition plan that will help treat root causes of autistic behaviors and assist you in helping them reach their nutritional recommendations. By following certain diets, participating in feeding therapy, healing the gut, and decreasing systemic inflammation, we are able to treat many behavioral symptoms that stem from these underlying nutrition and medical problems without medications in order to help heal your child from the inside out. A large majority of people see great improvements in their child's behavior, academic performance, cognition, and gastrointestinal symptoms, which all contribute to autistic behaviors. Just as every child is different, every child's improvement will be different.
