Different dietary patterns in relation to age and the consequences for intake of food chemicals.

This paper principally addresses the question of whether exposure to food additives/contaminants is likely to be higher in children than adults. Food consumption surveys conducted in the United Kingdom indicated that 99% of infants were receiving some solid food at 6 months of age (mean age of introduction 13 weeks), mainly 'family' foods not specifically produced for infants. On a body weight basis, young children, age 1 1/2-4 1/2 years, were shown to consume more than adults most notably of dairy products, puddings and confectionery (up to five times adult intakes) and of soft drinks (up to 16 times adult values). Two examples of risk assessments are given, for chlorinated dibenzodioxins and saccharin, where the intake was highest in children, in some cases exceeding the Provisional Tolerable Weekly Intake or Acceptable Daily Intake, respectively. The necessary risk management measures taken are discussed.
