Children with autism spectrum disorders (ASD) have several risk factors for low bone mineral density. The gluten-free, casein-free (GFCF) diet is a complementary therapy sometimes used in ASD that raises concerns for the adequacy of calcium and vitamin D intake. This study evaluated the prescribing practices of calcium and vitamin D supplements and the practice of checking 25-hydroxy vitamin D (25(OH)D) levels by providers in 100 children with ASD, 50 of whom were on the GFCF diet. Fifty-two percent and 46% of children on the GFCF diet were on some form of vitamin D and calcium supplements, respectively, compared to 18% and 14% of those not on this diet...

BACKGROUND: Autism spectrum disorders (ASDs) are a group of developmental disabilities in childhood and adolescence. Beside genetic predisposition also environmental influences may contribute to the ASD pathogenesis. Family members of children and adolescents with ASD often ask for specific diets to alleviate ASD-associated symptoms. The aim of this review is to provide evidence-based data on nutritional interventions for children and adolescents with ASD, thus enabling practitioners to competently assess these diets...

To obtain information on the safety and efficacy of the gluten-free/casein-free (GFCF) diet, we placed 14 children with autism, age 3-5 years, on the diet for 4-6 weeks and then conducted a double-blind, placebo-controlled challenge study for 12 weeks while continuing the diet, with a 12-week follow-up. Dietary challenges were delivered via weekly snacks that contained gluten, casein, gluten and casein, or placebo. With nutritional counseling, the diet was safe and well-tolerated. However, dietary challenges did not have statistically significant effects on measures of physiologic functioning, behavior problems, or autism symptoms...

BACKGROUND: Little is known about the effect on dietary adequacy of supplements given to children with autism spectrum disorder (ASD). OBJECTIVE: This cross-sectional study examines dietary supplement use and micronutrient intake in children with ASD. DESIGN: Three-day diet/supplement records and use of a gluten/casein-free diet (GFCF) were documented. Estimates of usual intake of micronutrients from food and supplements were compared with the Dietary Reference Intakes...

On the basis of review of the published literature,limitations in current data do not support the use ofa gluten-free and casein-free diet (gfcf-d) asa primary autism spectrum disorder (ASD) treatment.(13)(25)(26)(36) On the basis of clinical opinion, given the popularity of parents seeking a gfcf-d for their children with ASD, clinicians should acknowledge family’s concerns and provide appropriate information about a gfcf-d toguide them and prevent possible harm.

Dietary intervention as a tool for maintaining and improving physical health and wellbeing is a widely researched and discussed topic. Speculation that diet may similarly affect mental health and wellbeing particularly in cases of psychiatric and behavioral symptomatology opens up various avenues for potentially improving quality of life. We examine evidence suggestive that a gluten-free (GF), casein-free (CF), or gluten- and casein-free diet (GFCF) can ameliorate core and peripheral symptoms and improve developmental outcome in some cases of autism spectrum conditions...

BACKGROUND: One in 110 children in the US have autism spectrum disorder (ASD), a debilitating and life-long disorder that affects the health, relationships, and learning of affected children. Existing research on the etiology, contributing factors, and treatment for ASD is limited and controversial. Studies suggest that GI symptoms are related to behavior issues in children with ASD, which may be improved by a gluten-free, casein-free (GFCF) diet. OBJECTIVES: To evaluate the relationship between a GFCF diet and gastrointestinal symptoms and behavior patterns in children with ASD...

OBJECTIVES: Studies on the gluten-free and/or casein-free (GFCF) dietary intervention for children with autism spectrum disorders (ASDs) suggest that some children may positively respond to implementation of the dietary intervention. Other research suggests that children diagnosed with ASD can be classified into subpopulations based on various factors, including gastrointestinal (GI) abnormalities and immune function. METHODS: This study analyzes parental report data collected using a 90-item online questionnaire from 387 parents or primary caregivers of children diagnosed with ASD on the efficacy of the GFCF diet...

The prevalence of classic autism and autism spectrum disorder (ASD) appears to be on the rise, and to date, there remains no clear etiology or cure. Out of desperation, many families are turning to new therapies and interventions discovered through various media sources and anecdotal reports from other parents. Unfortunately, many of these newer, well-publicized interventions have little empirical support. One of the most popular yet currently scientifically unproven interventions for ASD is the gluten-free, casein-free (GFCF) diet...

Consumption of macro- and micronutrients and food group servings by children with autism spectrum disorders (ASDs; n = 46) and typical development (n = 31) were compared using 3-day diet records. Children with ASDs consumed significantly more vitamin B6 and E and non-dairy protein servings, less calcium, and fewer dairy servings (p < .05). The significantly lower dairy serving intake persisted after controlling for child age and sex and parental dietary restrictions, and excluding children on the gluten-free casein-free (GFCF) diet...

This study tested the efficacy of a gluten-free and casein-free (GFCF) diet in treating autism using a randomized, double blind repeated measures crossover design. The sample included 15 children aged 2-16 years with autism spectrum disorder. Data on autistic symptoms and urinary peptide levels were collected in the subjects' homes over the 12 weeks that they were on the diet. Group data indicated no statistically significant findings even though several parents reported improvement in their children. Although preliminary, this study demonstrates how a controlled clinical trial of the GFCF diet can be conducted, and suggests directions for future research...
