Researchers from the University of Liverpool found the change could save lives across England and cut the number of overweight people
More than 100,000 obesity-related deaths could be prevented in the next two decades if food companies were forced to make a change, according to health experts. Researchers from the University of Liverpool discovered that warning labels for foods high in fat, salt or sugar placed on the front of packaging – as seen in several other countries – could save lives across England and reduce the number of overweight people.
Chile was the first country to introduce a mandatory nutritional warning label law in 2016, requiring food and drink high in fat, salt or sugar to display a black octagonal warning on the front of packs. Other nations, including Mexico and Canada, have followed suit with similar changes.
In the UK, while it is compulsory for nutrition information to be displayed on the back of all food packaging, putting any details on the front, such as the traffic light system, is voluntary.
In a new study published in the Lancet Regional Health – Europe, experts used modelling to see what differences mandatory warning labels could make.
Looking at the 20-year period from 2024 to 2043, they estimated that mandatory implementation of traffic light labelling could reduce obesity prevalence by 2.34 percentage points and prevent or postpone 57,000 obesity-related deaths.
However, mandatory implementation of nutrient warning labelling, as seen in other countries, would have a more significant effect, with a 4.44 percentage point reduction in obesity prevalence and 110,000 fewer obesity-related deaths.
The authors have urged the Government to consider implementing nutrient warning labels. Dr Rebecca Evans, corresponding author of the study, said: “Our findings suggest that mandatory nutrient warning labels could deliver substantial health benefits for the population, reducing both obesity rates and related mortality.
“These results support current government discussions about alternative labelling approaches and provide robust evidence to guide future UK food labelling policy.”
Dr Zoe Colombet, a contributor to the study, added: “Nutrition labels are a simple yet powerful tool. Making them mandatory could help people make healthier food choices and encourage the food industry to rethink what goes on our shelves, helping to prevent thousands of deaths linked to obesity”.
Amanda Daley, professor of behavioural medicine at Loughborough University, also said: “We need effective public health interventions to reduce the number of deaths related to people living with obesity and mandatory warning labels on food may be one way to achieve this.
“Importantly, we need the food industry to play their part in helping people to make informed decisions about the food they purchase and consume. The requirement for food manufacturers in the United Kingdom to include warning labels may encourage the sector to consider more carefully the contents and portion size of food items that they sell. Let’s not forget, the public have the right to be fully informed about the impact of the food they consume on their health.”
Dr Jordan Beaumont, from Sheffield Hallam University, wrote that whilst the traffic light system is a “useful tool for consumers”, he did highlight that it could be “tricky to interpret in context of our wider food choices and dietary intake.”
He explained: “Given we often have very little time to actually inspect labelling and make truly informed decisions when shopping for food, nutrition warning labels provide simpler and more explicit information that is quick and easy to interpret, which explains the larger impact of such information in this modelling.”
Andrea Martinez-Inchausti, assistant director of food at the British Retail Consortium, which represents retailers, concluded: “Retailers are fully committed to helping improve the health of their customers and have been consistent in providing advice on healthy living, including providing nutritional information on all their products. Supermarkets have also keenly adopted the traffic light system for nutritional information on their own products.”
