calcium (4). In addition, elimination diets increase the risk of inadequate nutrient<br />

status. There have been reports of impaired bone growth in boys <strong>with</strong> autism, as<br />

measured by bone cortical thickness (BCT) (5). These changes were seen in boys<br />

whether they were on a restricted diet or not, but there was lower BCT in those on a<br />

gluten-free, casein-free diet.<br />

Alternative <strong>Nutrition</strong> <strong>Interventions</strong><br />

There are many diet-based interventions to treat ASD, although scientific evidence<br />

confirming their efficacy is limited. Sophisticated marketing, testimonials, and<br />

claims have prompted many parents to adopt dietary changes and supplementation<br />

regimens <strong>for</strong> their children <strong>with</strong> ASD. The plethora of in<strong>for</strong>mation available to parents<br />

and families on the Internet provides added challenges to RD’s and other health care<br />

providers.<br />

The most common nutrition interventions include:<br />

• Gluten-free/casein-free diet<br />

• Specific carbohydrate diet (SCD)<br />

• Yeast-free diet<br />

• Vitamin supplement <strong>for</strong> ASD, i.e. “Super Nu-Thera®”<br />

• Specific nutrients – B6, magnesium<br />

• Fatty acid supplements<br />

• Probiotics<br />

• Enzymes<br />

• Dimethylglycine (DMG)<br />

Gluten-free/casein-free (GFCF) diet<br />

The GFCF diet is the most popular dietary treatment intervention <strong>for</strong> children <strong>with</strong><br />

ASD. The “leaky gut syndrome” (also called the opiate theory) is part of the basis<br />

<strong>for</strong> using the diet, and was originally developed by researchers in Europe (6,7). The<br />

theory is that children <strong>with</strong> ASD cannot properly digest the casein and gluten in dairy<br />

and wheat foods, leaving partially broken down polypeptides. With more permeable<br />

or “leaky” intestines, these polypeptides are believed to enter the circulatory<br />

system, passing through the blood-brain barrier. There they <strong>for</strong>m compounds <strong>with</strong><br />

endorphin receptors in the brain, causing some of the characteristics and behaviors<br />

seen in children <strong>with</strong> ASD. Removal of casein and gluten from the diet is there<strong>for</strong>e a<br />

treatment.<br />
