Abstract:  A questionnaire evaluation of 486 hyperactive children (HA) (82% boys, aged 7-13 years and IS% girls, aged 8-13 years) showed that more than 60% of cases reported a positive behavioural response (i.e. increased problems) in relation to consuming or being exposed to synthetic colourings and flavourings, food and beverage preservatives, cow's milk and associated products, chemical detergents and perfume. 

In contrast, 172 sex- and age-matched control children (C) reported only 12% of cases responding to synthetic colourings and flavourings and chemical solvents. 

The main health problems reported by the 96% of hyperactive children affected by synthetic colourings and flavourings were persistent thirst problems, the development of eczema, ear and/or chest infections, and the production of excessive amounts of catarrh. 

Trace element measurements undertaken by inductively coupled plasma mass spectrometry showed that a low zinc and iron status is associated with hyperactive children when compared with control children.
