World Community Autism Program

World Community Autism Program is a not-for-profit organisation founded in 2001 by autism researchers Sandra and Max Desorgher who have been advocates of a holistic nutritional approach to autism since 1994. They developed a lutein-free diet program, known as Sara's Diet,, also known as the Lutein-free diet, which has led to recoveries and significant improvements for people diagnosed with autism spectrum disorders and has been described as beneficial by the National Autistic Society, UK.

"Single cause" theory
In 2000, Positive Health magazine published an article by the Desorghers called "Autism: Dietary Treatment Options", which explains the theory on which the lutein-free approach is based. In this theory, autism is seen as a neuro-gastro-immunological disorder resulting from an immunogenetic error during fetal development rather than as a psychological condition. According to this theory, the developing immune system selects lutein as a non-self pathogen. Autistic behaviors begin to emerge during early childhood as lutein-containing foods increasingly enter the infant's diet, triggering immune system responses as well as neurological and metabolic changes. This theory was further explained in "Autism, Pigments and the Immune System", published in 1999.
