The campaign group Action on Sugar is demanding a ban on freakshakes and all milkshakes with more than 300 calories. It surveyed milkshakes sold in restaurants and fast food shops in the UK and found they contained “grotesque levels of sugar and calories”. Freakshakes are milkshakes that also contain chocolates, sweets, cake, cream and sauce. The Toby Carvery Unicorn Freakshake came top of the survey with 39 teaspoons of sugar or 1,280 calories. That is more than half the daily recommended amount of calories for an adult and over six times the amount of sugar recommended for seven to 10-year-olds. It is the equivalent of drinking more than four cans of cola. The British Heart Foundation calculates an average 25-year-old would need to jog for nearly three hours or vacuum the house for five hours to burn off the calories. The researchers found that many other shakes contain more than half the daily recommended amount of calories for an adult. They say that of the 46 products included in the survey with nutrition labelling available online, all would receive a red/high label for excessive levels of sugar per serving. Action on Sugar, which is made up of specialists concerned with sugar and its effects on health, are calling for mandatory traffic light-coloured nutrition labelling across all menus. The government is currently consulting on menu calorie labelling. Public Health England (PHE) also has a sugar reduction programme as part of the government’s childhood obesity plan. It is challenging businesses to cut sugar by 20% by 2020 and milkshakes are included in that. Action on Sugar chairman Graham MacGregor, professor of Cardiovascular Medicine at London’s Queen Mary University, said that does not go far enough. “These very high calorie drinks, if consumed on a daily basis, would result in children becoming obese and suffering from tooth decay – that is not acceptable,” he said. “These high calorie milkshakes need to be reduced immediately below 300kcal per serving.” Registered nutritionist Kawther Hashem, a researcher at Action on Sugar based at Queen Mary, said it was “shocking this information is hidden from the consumer, who would struggle to find it”. She said it was “time the government introduced legislation to force companies to be more transparent about what is in their products”.
