Allergy testing, psychological assessment and dietary treatment of the hyperactive child syndrome.
Salzman LK
Thirty-one children with behavioural problems and learning difficulties were allergy tested for sensitivity to salicylates, artificial colours and flavours, eighteen children had a positive response, and 15 of these were given the Australian Version of the Feingold K.P. diet. Ninety-three per cent responded with improved behaviour in the areas of overactivity, distractability, impulsiveness and excitability. Sleep and enuresis problems were resolved partially or completely. This study demonstrates that the aforementioned elimination diet significantly affects behaviour.
