Oh dear. The latest moral panic gathers pace."All the evidence indicates that per capita consumption of sugar,salt, fat and calories has been falling in Britain for decades. Percapita sugar consumption has fallen by 16 per cent since 1992and per capita calorie consumption has fallen by 21 per centsince 1974""According to the British Heart Foundation (2012 :107):‘Overall intake of calories, fat and saturated fat has decreased sincethe 1970s. This trend is accompanied by a decrease in sugar andsalt intake, and an increase in fibre and fruit and vegetable intake.’http://www.iea.org.uk/sites/default/files/in-the-media/files/Briefing_The%20Fat%20Lie.pdf
iea, as in the Institute of Economic Affairs, the think tank that has been revealed to happily do some lobbying on behalf of the tobacco industry in return for some funding?

Not a very credible source on issues of public health.

And how about DEFRA?"This statement may come as a surprise to some people, but it isfactually correct. All the available data support it. The Departmentfor Environment, Food and Rural Affairs (DEFRA) has carried outannual surveys of the British diet since 1974. These surveys arebased on diet diaries compiled by a cross-section of the public andare supported by till receipts (DEFRA, 2013)."
Such is my contempt for organisations that lobby for the tobacco industry that I'm not going to follow any links to the Institute of Economic Affairs. But now that you have mentioned DEFRA 2013 (your first post didn't mention DEFRA), I have not only located that report, but also skimmed through it. (It can be found here: https://www.gov.uk/government/uploads/system/uploads/attachment_data/file/38... if anyone is interested.)
What exactly is DEFRA 2013 supposed to prove? Reading it does very little to convince me that there shouldn't be warning labels on sweet drinks. I see in chart 2.3 that consumption of soft drinks (not including water and fruit juice) has increased since 1992. There's a quite drastic increase in purchases of "low-calorie" soft drinks in recent years. Presumably that's because people have switched to artificially sweetened beverages? As you can tell from one of my posts above I don't think using artificial sweeteners is better than using sugar. I think it's just as bad or even worse. I can't find any diagram showing how the intake of artificial sweeteners and other sugar substitutes has changed over the years. My guess would be that the use of artificial sweeteners has skyrocketed in recent decades?
The IEA say "These surveys are based on diet diaries compiled by a cross-section of the public and are supported by till receipts", but if you check DEFRA 2013 it says: "Survey participants record their food and drink purchases in a two week diary. They are able to attach till receipts or to write in diary entries to cover amount spent and quantity purchased for each individual item." That's a bit different. Participants can attach till receipts if they want to. No doubt the IEA want to give the impression that the survey is very accurate. But to think that the numbers in the survey are very accurate would be a mistake I think. I've found an article discussing problems with Dietary Intake Studies:
http://www.theatlantic.com/health/archive/2012/03/why-calories-count-the-problem-with-dietary-intake-studies/254886/
A quote from that article: "Nutrition scientists have put enormous effort into trying to evaluate the magnitude of reporting errors. They find that people underestimate their true calorie intake by astonishing percentages, typically 30 percent, with a range of 10 to 45 percent depending on such factors as age, sex, body composition, and socioeconomic status. Underreporting of food -- and therefore calorie intake -- increases with age and is greater among women, people who are overweight, and those of low education and income status. People also tend to exaggerate intake of foods they think are supposed to be good for health".
The section in "DEFRA 2013" that discusses potential problems and inaccuracies in the survey is way too short.
