"There are strong connections between the immune system and the brain, which are mediated through multiple physiological symptoms," Klein said. "A majority of the pain receptors in the body are located in the gut, so by adhering to a gluten-free, casein-free diet, you're reducing inflammation and discomfort that may alter brain processing, making the body more receptive to ASD therapies."
The team found that parents who eliminated all gluten and casein from their children's diets reported that a greater number of their children's ASD behaviors, physiological symptoms and social behaviors improved after starting the diet compared to children whose parents did not eliminate all gluten and casein. The team also found that parents who implemented the diet for six months or less reported that the diet was less effective in reducing their child's ASD behaviors.
According to the researchers, some of the parents who filled out the surveys had eliminated only gluten or only casein from their children's diets, but survey results suggested that parents who completely eliminated both gluten and casein from their child's diet reported the most benefit.
"While more rigorous research is needed, our findings suggest that a gluten-free, casein-free diet might be beneficial for some children on the autism spectrum," Pennesi said. "It is also possible that there are other proteins, such as soy, that are problematic for these children."
The reason Klein and Pennesi examined gluten and casein is because they are two of the most common "diet offenders."
"Gluten and casein seem to be the most immunoreactive," Klein said. "A child's skin and blood tests for gluten and casein allergies can be negative, but the child still can have a localized immune response in the gut that can lead to behavioral and psychological symptoms. When
