Speaking during Obesity and health, the big fat, sugar and salt debate , which aired on July 3, Graham MacGregor, professor of cardiovascular medicine at the Wolfson Institute of Preventive Medicine, said: “We know that duties … work.
“If you look at cigarettes, look at alcohol, the higher the tax, the lower the consumption. Certainly my view is that we should plan in the UK to put a tax on sugar as a threat to the food industry in order to get them to conform to targets and we could have regulatory targets for sugar.
“That’s been done in many countries for salt across the world and we know exactly how to do this and we can do the same for fat.”
MacGregor cited the tax on sugary soft drinks in France, claiming the latest information indicated that it was reducing sweetened, soft carbonated drink consumption. Mexico, which had exceptionally high obesity rates, has also imposed a duty on sugar, he added.
However, he continued: “Yes, it would work; the question is: would the government do it and the government’s more likely to go for a voluntary reformulation, which has worked for salt, albeit a lot more slowly than what we would like.”
He warned the poorest people in the UK had no choice over what they would eat – they had to buy the cheapest products, so these needed to be reformulated.
Dr Charlotte Evans, lecturer in nutritional epidemiology and public health nutrition at the University of Leeds, said: “There’s a lot of emphasis on individuals making the decision; it’s no good if you target reformulation, but then market and advertise foods high in fat, sugar and salt, put them on the end of [supermarket] aisles.
“We need a holistic approach … we are in a position where the cheapest foods are not good for our health and so I think that tax is a very good idea, and of course evaluating to make sure we do identify any unforeseen circumstances as well.”
However, Barbara Gallani, director of regulatory affairs, science and health at the Food and Drink Federation (FDF) cited figures that cast doubt on the effectiveness of tax as an incentive.
‘Not particularly successful’
“There are examples of taxes that have been tried in other countries and they have not been particularly successful. I was looking the other day at data from France [on soft drinks tax].
“Although in 2012 the volumes of sales decreased by two percent, in 2013 the volumes grew by 0.5% and since the beginning of 2014, they have increased by a further six percent.”
Barbara stressed the food industry had successfully brought down salt content in foods and cited FDF members’ recent commitment to deliver a 250 calorie cap on single-serve confectionery items by spring 2016.
As part of the Department of Health’s Public Health Responsibility Deal, these efforts, together with continued initiatives to cut saturated fat content, showed the industry was willing to make a difference.
However, MacGregor called the Responsibility Deal “a dead duck in the water”, insisting it wasn’t working and a common reporting mechanism and clearer targets were needed.
Three influential groups – the Institute of Food Science & Technology, the British Dietetic Association and the Nutrition Society – backed the webinar in a bid to introduce more science into the obesity debate.
