Sugar statistics for everyone to ignore

Mike Gibney has dug out some sugar statistics from around the world to show, for the umpteenth time, that sugar consumption has not been rising during the obesity 'epidemic'.

The Food & Agricultural Organisation (FAO) of the UN measures the “disappearance” of sugar in countries worldwide which takes overall national production data, adds imports and subtracts both exports and non-human use. If used wisely and for time trends only, such data can be very valuable.

In Australia, such data shows a decline in per capita intake of sugar from 152 grams per day in 1980 to 127 in 2011. Using similar techniques, data from the Australian Bureau of Statistics shows a 17% reduction in apparent sugar consumption from 1961 to 2011 (139 to 115g/hd/d). Data from Australian National Nutrition Surveys, which are based on surveys of actual sugar intake at individual level, also show a decline in total sugar intake, from 115 grams per day in 1995 to 105 in 2012. Given that among the devils of sugar sources, those from beverages are considered as the Satanic level, it is interesting to note that such Satanic influences have also fallen over time.

No matter how defined (soft drinks, sugar sweetened beverages, sugary products, sodas plus juices etc.), the time-related decline of sugar intake in liquid form is still obvious. Data from industry sources were also made available to the authors and once again, no matter how defined, the same pattern of a decline in solid and liquid sugar intake is seen. For example, the % of children classified as “consumers “ of sugar-sweetened beverages declined from about 65% in 1995 to 25% in 2012. Energy from sugar-sweetened beverages plus juices in children fell from an average of 9.2 % of calories in 1995 to about 5.5% in 2012. All in all, there is not a shred of evidence from the either global overview or the Australian deep-dive into sugar intakes to suggest any rise whatsoever in sugar intakes.

Facts don't make any difference in this debate, of course. People believe whatever they want to believe and I sympathise with Mike's frustration:

Why therefore do we suffer the avalanche of data telling us about the poisonous nature of sugar and the wicked damage it is doing to the health of our children? In my view this is a consequence of our post truth era where post-truth is defined by The Oxford Dictionary as: ‘An adjective relating to or denoting circumstances in which objective facts are less influential in shaping public opinion than appeals to emotion and personal belief’.

You see, sugar was extracted on the back of the global slave trade and is now used by corporate food giants to manipulate the food supply to make a tasteless mechanically derived ultra-processed foods into ones which are rendered hyper-palatable with copious levels of added sugars. Gurus from California with impeccable medical backgrounds have shown conclusively that sugar is toxic, the new tobacco in fact. Tax the damn thing and be done with it!

That’s the emotional argument. It wins out every time against the peer-reviewed data cited in this blog. As a life timer in nutrition I have come to accept this and other such misuse of nutritional data and its adaptation by populist experts and governmental departments.

Last week another study came out showing a decline in sugar consumption in Australia over the last thirty years. This is laughably called the 'Australian paradox' because (a) it is assumed that sugar consumption must have risen if obesity has risen, and (b) it is assumed that sugar consumption has risen in other countries.

Neither assumption is true, but that hasn't stopped one anti-sugar fanatic hounding those who prefer data to doctrine. Rory Robertson set up a green ink website several years ago attacking Jennie Brand-Miller and Alan Barclay after they published a study showing a fall in sugar consumption over several decades. He even managed to get Sydney University to investigate the pair, both of whom were cleared of any misconduct.

Robertson has since been threatened with being banned from Sydney University for allegedly acting in an 'aggres­sive and intimidating manner'. You won't be surprised to hear that Robertson gave up eating sugar, lost weight and is now something of a crusader. Thanks to his n=1 study, he seems to think that sugar is the sole cause of obesity.

I don't know what it is about giving up sugar that makes people so angry but I see a lot of it Twitter. Perhaps we will one day discover that carbs are good for mental health.
