This study found that majority of respondents offered their children sunnah food, Omega-3 supplements and vitamin and mineral supplements, omitted food additives, gluten and casein, seafood, egg and legumes as they thought these may help in improving their children’s behavior and health. The main sources of information regarding these food practices were Autism Club Malaysia, internet, doctor and religious teacher.
