Latest evidence of the Gluten Free Casein-Free Diet in Autism Spectrum Disorders
The evidence to support GFCF diets in treatment of children for ASD remains weak and inconclusive. However success is possible for a subset of children who have gastrointestinal problems (constipation, diarrhea, bloating) and food sensitivities. Here’s a quick summary from my review of two recent scientific papers:
–Children predisposed to GI problems might particularly benefit from a GFCF dietary intervention.
–Children with allergy symptoms also demonstrated improved ASD symptoms on GFCF diet.
–The better the compliance to the diet, the greater the improvement in symptoms.
–Drawbacks to the diet include: 1) nutritionally inadequate in calcium, phosphorus, vitamin D, magnesium and other minerals; 2) social stigmatization and difficulty in complying with the diet.
–Probiotics containing lactobacilli provide protection against infection in the gut and healthy immune function.
–Work closely with a dietitian in monitoring dietary adequacy and choosing an appropriate vitamin and probiotic supplement.
