In Australia, the UK and USA, per capita consumption of refined sucrose decreased by 23%, 10% and 20% respectively from 1980 to 2003. When all sources of nutritive sweeteners, including high fructose corn syrups, were considered, per capita consumption decreased in Australia (−16%) and the UK (−5%), but increased in the USA (+23%).
Furthermore, there was a reduction in Australian sales of sweetened beverages by 64 million litres from 2002 to 2006 and a reduction in the percentage of Australian children consuming sugar-sweetened beverages between 1995 and 2007.
Despite this, the prevalence of obesity increased threefold in Australia since 1980.
The findings confirmed what the Aussie researchers labelled an Australian Paradox a substantial decline in refined sugar intake over the same period that obesity increased markedly.
As the researchers noted, the implication of these findings is that efforts to reduce sugar intake may reduce consumption but may not reduce the prevalence of obesity.
