PrepTest 49, Section 3, Question 20
Magazine article: Sugar consumption may exacerbate attention deficit disorder (ADD) in children. A recent study found that children produce large amounts of adrenaline within hours after consuming large amounts of sugar. This increase in adrenaline is especially noticeable if the source of sugar is candy, in which case the sugar's effects are not ameliorated by the ingestion of other foodstuffs.
