Biomedical Intervention

Before you read any further, take a few minutes to watch this startling video. It will remove any doubts you may have that food can affect behaviour.


What is meant by the term "biomedical"? The description by Dr. Sid Baker (see Resources) refers to the fundamental principle of biology - the individuality of each living creature. Treatment options are unique for each patient.

Although biomedical interventions may not help every child, to date they have helped thousands of children improve, sometimes quite drastically. Parents play an active role in the evaluation of which options prove helpful for their child.

Healing the Intestines

Research has shown that the majority of autistic children suffer from bowel problems such as persistent diarrhea or constipation, foul-smelling stools, bloating or abdominal pain. Since these children often cannot verbally express how they feel, they may exhibit behaviours that are an attempt to alleviate their pain, e.g. pressing their stomach against a chair.


Many practitioners who care for the medical needs of autistic children consider diet as the first step of biomedical intervention. In fact, Dr. Jaquelyn McCandless (see Resources) believes so strongly in healing the gut, that she will only accept new patients whose parents are willing to implement a diet free of gluten, casein and soy.

The basic strategies for healing the gut are to:

  1. remove foods that are harming the child's intestines (e.g. gluten, casein)
  2. supplement with essential vitamins, minerals and fatty acids
  3. add probiotics and digestive enzymes.

As the intestines are healed, there is often a significant improvement in the behaviours of an autistic child.
