FAB RESEARCH COMMENT:
This study adds some new experimental evidence to the longstanding question of whether opioid-like peptides derived from A1 beta-casein (found in cows' milk) may play a role in autistic spectrum disorders (ASD) - and related conditions.
Previous studies - like this one - have found some evidence of abnormal peptide profiles in at least a subset of children with ASD, but as usual, differences in the populations studied and methodologies used have made any clear conclusions difficult.
As usual - more research is needed, as discussed by Paul Whiteley in his 'Questioning Answers' blog, and the associated FAB comment.
