Doctors call on workplaces to ban the sale of sugary drinks

Research at the University of California shows a ban slashed staff’s intake by nearly half.

Doctors have called on workplaces to ban sales of sugary drinks after research showed that removing them from cafes, canteens and vending machines helped reduce people’s waistlines and improve their health.

Researchers monitored more than 200 staff at the University of California in San Francisco and its associated hospital after a ban was introduced in 2015. Before the ban, the participating staff consumed on average more than a liter of sugary drinks daily, but 10 months later had slashed their intake by nearly half.

Medical assessments of the staff found they had lost an average of more than 2cm around the waist, and that those who reduced their sugary-drink intake tended to have better insulin resistance and lower cholesterol.

“A simple sales ban has meaningful effects on employees’ health,” said Elissa Epel, a professor of psychiatry who led the work. “This is very exciting news because to eliminate sales of sugary beverages is something any institution can do.” The ban was only on sales and did not prevent people from bringing sugary drinks to work, or buying them off-site.

Beyond investigating the impact of the sales ban itself, Epel randomly assigned half of the staff to also receive a motivational intervention. This involved showing them how much sugar they were consuming – for example, one sugary drink per day was equivalent to a plastic cup half full of sugar cubes. The staff was also given information on how sugar harms health and was helped to identify reasons they might want to adopt a healthier lifestyle.

According to the report in the journal Jama Internal Medicine, sugary drink intake fell 49% on average. The sales ban alone allowed staff to cut their sugary drinks by 23% (246ml) daily. But the intervention had a greater impact, prompting staff to reduce their intake by 73% (762ml) daily.

“We found that for people with overweight or obesity if they also got a brief counseling discussion, they showed significant reductions in their lipid levels as well. So for heavier people, the extra attention really mattered to them. They benefited the most,” said Epel.

Laura Schmidt, a co-author of the study, said the permanent ban on sugary drinks sales at UCSF was an obvious move. “These days, most of what we are treating in our healthcare system are chronic diseases, such as diabetes, heart disease, cancers and Alzheimer’s. All of these conditions can be linked back to the calorie-dense, nutritionally poor standard western diet”, she said. “It made sense for a health sciences campus like UCSF to say no to profiting off the sales of products that cause the very diseases we treat in our hospitals and clinics.”

Aseem Malhotra, an NHS consultant cardiologist, and professor of evidence-based medicine, said: “This latest research not only solidifies the evidence that the positive health impact of sugar reduction is independent of body weight, but that removing the sale of sugary drinks from the working environment is a key solution to combating diet-related disease amongst staff.

“It’s an absolute scandal that our hospitals have become a branding opportunity for the junk food industry and not surprising that more than 50% of healthcare staff are now overweight or obese. If we truly want to reverse obesity and its associated diseases we must stop selling sickness in the hospital grounds.”

Simon Stevens, the NHS chief executive, said: “Since the NHS first asked hospitals to reduce sales of sugary drinks we have removed over 32 million teaspoons of sugar – or the equivalent of around 900,000 cans of fizzy pop.

“Obesity is a dangerous public health threat, leading to a string of serious illnesses for millions, with thousands of people ending up in hospital as a result, so every industry needs to take a look at what it can do to support urgent action like reducing sales of sugary drinks to prevent harm and safeguard children.”
