Sugar blamed for UK obesity: how much is in our food?

Experts want to banish sugary drinks at meal times and cut recommended sugar intake in half

LAST UPDATED AT 10:15 ON Fri 14 Nov 2014

As UK obesity increases, sugar is increasingly under attack. Experts want to banish sugary drinks for children and cut the current sugar guidelines for men and women in half. Cola drinks, lemonade and even fruit juice are major contributors to the obesity epidemic, experts have said, and a particular problem for children who consume more of them than adults. Campaigners have been urging the government to introduce a sugar tax for months, describing sugar as the "new tobacco". But is it really that bad?

How much sugar should we eat?

The recommended daily guidelines for added sugar are currently 70g (17.5 teaspoons) for men and 50g for women (12.5 teaspoons), depending on a person's size, age and activity levels. But the Scientific Advisory Committee on Nutrition this week recommended that this should be cut in half. This would mean just one 330ml can of Coke (35g sugar), a 250ml glass of cranberry juice (36.3g sugar) or a Mars bar (33g sugar) would exceed limits for women and take up most of the mens' daily intake.

Why the concern about sugar now?

Sugar has been cast as the villain of Britain's obesity crisis. A third of British children and two-thirds of British adults are obese or overweight, with diabetes levels doubling in the past two decades. Obesity and diabetes already costs the UK more than £5bn every year and this is likely to rise to £50bn in the next 36 years.

But is sugar really to blame?

Representatives from Action for Sugar, a campaign group of health experts and academics, say that sugar is "the new tobacco" pushed on unsuspecting parents and children by "a cynical industry focused on profit not health". Sugary foods and drinks cause tooth decay and can contribute to people becoming overweight, which increases risk of heart disease and type 2 diabetes, says the NHS.

But others, including many in the sugar and confectionary industry, argue sugar alone is not to blame. Over-consumption of calories from all types of food, including fats and alcohol, and our increasingly sedentary lifestyles have caused obesity, they say. The British Dietetic Association has acknowledged that there is little evidence to say that sugar itself causes type 2 diabetes and research from Sugar Nutrition UK, funded by the World Health Organisation, found that "any link to body weight was due to overconsumption of calories and was not specific to sugars".

Should we stop drinking juice?

The NHS notes that fruit juice is "still a healthy choice", with one 150ml serving counting towards your five a day. However, it says that any more than this does not count towards the fruit quota and recommends that it is drunk with a meal to avoid tooth decay. It also says that we should not cut down on fruit as it is an important part of a healthy diet.

How can sugar content be reduced?

Many food companies have voluntarily agreed to cut sugar in their products by ten per cent under the government's Responsibility Deal, but academics say this does not go far enough. Here are some of the ideas currently up for debate:

  • Better packaging: It is not just sugary drinks and sweets that are the problem, many people are unaware of the sugar levels in other products such as soups, ready meals and cereals. So-called "hidden sugars" are often listed as glucose, sucrose or fructose and it can sometimes be hard to tell if sugar content is natural or added. Nutritionist Katharine Jenner, of Action on Sugar, tells the BBC it is "nigh on impossible" for people to work out how much added sugar they are consuming.
  • Reduce sugar levels in products: Action on Sugar has calculated that reducing sugar in processed foods by between 20 and 30 per cent over the next three to five years could remove 100 calories a day from diets, which it claims is enough to halt or reverse the obesity epidemic.
  • Ban on advertising: The campaign group has also asked companies to stop advertising sugary drinks and snacks to children.
  • Sugar tax: Health Secretary Jeremy Hunt has ruled out a sugar tax, but campaigners continue to argue that it would help curb obesity. A study by Oxford University last year suggested that a 12p tax on fizzy drinks would cut consumption by 15 per cent and mean 180,000 fewer obese adults. However, Prof Richard Tiffin, director of the Centre for Food Security at the University of Reading, says that many other studies suggest it would not work. "The real battleground is in the mind of the consumer," he writes in the Daily Telegraph.
