There has been debate surrounding a paper “The Australian Paradox” which reported the observation that upward changes in the prevalence of overweight and obesity in Australia run counter to changes in refined sugars intake. Unfortunately, the "debate" has not been conducted in a very civil manner, and has become amongst other things, a series of ad hominen attacks.
An Australian economist claims there is no Australian Paradox, just unreasonable treatment of the available data. However, in critiquing the Australian Paradox, the economist relies heavily on data from the Australian Bureau of Agricultural and Resource Economics and Sciences. Unfortunately, there are factual errors in the economist’s arguments, and misinterpretation of the distinctions between total sugars vs. refined sugars, sugar availability vs. apparent consumption, sugar-sweetened and diet soft drinks, and other nutrition information.
The economist also holds an erroneous belief that the sugar fructose is the primary cause of obesity, despite the existence of very strong evidence that fructose is no more fattening than any other form of carbohydrate when consumed in typical (physiological) amounts as part of a healthy balanced diet.
A detailed response to the economist has been published in the Australian Paradox Revisited paper, and a new independent review of Australian's sugar consumption indicates that it is still continuing to decline. A new analysis of sweetened beverage consumption has been published and it too confirms that sugars from these sources continues to decline. The Australian Government is currently conducting an Australian Health Survey to ascertain the dietary habits of Australians. It will provide further insight into trends in sugar consumption amongst Australian children and adults. This information is due for release in 2014.
The reason why added sugar consumption is decreasing in Australia is because Australians have taken public health messages to eat less sugar seriously, and have switched to using alternative sweeteners instead. However, perhaps surprisingly, there is little evidence that alternative sweeteners actually help people to reduce their added sugar or kilojoule intake.
Added refined sugars like sucrose, fructose and glucose are essentially devoid of nutrients other than kilojoules. It is therefore recommended that we consume no more than 10% of energy from added sugars. For someone consuming 8,700 kJ a day, this is equal to no more than 55 grams, or 13 teaspoons a day. It’s important to note that total not added sugars are listed in a foods nutrition information panel. It is therefore not necessarily appropriate to choose foods with less than 10% (10 g per 100 g) of (total) sugars as this may inadvertently lead to unnecessary exclusion of nutritious foods and drinks like fruits and certain dairy foods from the diet.
