This study involved a randomized, controlled, single-blind 12-month treatment study of a comprehensive nutritional and dietary intervention. Participants were 67 children and adults with autism spectrum disorder (ASD) ages 3-58 years from Arizona and 50 non-sibling neurotypical controls of similar age and gender. Treatment began with a special vitamin/mineral supplement, and additional treatments were added sequentially, including essential fatty acids, Epsom salt baths, carnitine, digestive enzymes, and a healthy gluten-free, casein-free, soy-free (HGCSF) diet. There was a significant improvement in nonverbal intellectual ability in the treatment group compared to the non-treatment group (+6.7 ± 11 IQ points vs. -0.6 ± 11 IQ points, p = 0.009) based on a blinded clinical assessment. Based on semi-blinded assessment, the treatment group, compared to the non-treatment group, had significantly greater improvement in autism symptoms and developmental age. The treatment group had significantly greater increases in EPA, DHA, carnitine, and vitamins A, B2, B5, B6, B12, folic acid, and Coenzyme Q10. The positive results of this study suggest that a comprehensive nutritional and dietary intervention is effective at improving nutritional status, non-verbal IQ, autism symptoms, and other symptoms in most individuals with ASD. Parents reported that the vitamin/mineral supplements, essential fatty acids, and HGCSF diet were the most beneficial.

BACKGROUND: An effective treatment for fibromyalgia (FM) has yet to become available. OBJECTIVE: To assess the efficacy ofa lifestyle program consisting of a modified elimination diet and a supplemental medical food on clinical symptoms of FM assessed by the Fibromyalgia Impact Questionnaire (FIQ), FibroQuest Symptoms Survey (FibroQuest), Medical Symptoms Questionnaire (MSQ), metallothionein mRNA expression, and urinary toxic element excretion. METHODS: Eight women (aged 48-74 years) were enrolled in an 8-week pilot trial employing a sequential design. During the initial 4-week Program A (control), participants consumed a modified US Department of Agriculture food pyramid diet and a rice protein powder supplement that provided basic macronutrient support. During the second 4-week Program B (intervention), participants consumed a modified elimination diet and a phytonutrient-rich medical food. RESULTS: Compared to baseline, both programs showed trends toward lower mean FIQ total score, MSQ total score, and FibroQuest total score, FIQ stiffness score, and FibroQuest headaches score. Compared to Program A, Program B resulted in a significant decrease (P< .05) in the FIQpain score and stiffness score. Participants also had better pain tolerance at five tender points during Program B than during Program A. Higher metallothionein mRNA expression was observed during Program B. An increase in creatinine-adjusted mercury excretion and suggestive increase in creatinine-adjusted arsenic excretion were noted when Program B was compared to baseline. Urinary mercury/arsenic concentrations were inversely associated with FIQand FibroQuest scores. CONCLUSIONS: Program B was shown to be a safe and efficacious botanically derived medical food treatment program for the amelioration of FM symptoms.
