This is according to the results of a new study led by Queensland University of Technology (QUT) academics and published in the journal Frontiers in Neuroscience. A trial using mice has shown that a diet high in sugar from childhood may lead to significant weight gain, persistent hyperactivity and learning impairments in adulthood. This has particular relevance to people on ‘western’ diets, many of whom consume four times more sugar than recommended by the World Health Organisation (WHO).
