‘Traffic light’ food labels reduce calories bought in health center cafeteria

by Lionel Casey

A new look at through Massachusetts General Hospital (MGH) investigators launched nowadays in JAMA Network Open, a book of the Journal of the American Medical Association, confirmed that labeling food selections in a hospital cafeteria with natural “visitors-mild” symbols indicating their relative fitness price became related to a discount in energy bought by personnel, and that the nutritional changes have been sustained over the years.

In this system, new labels indicated the healthiest ingredients, yellow names indicated much less healthy foods, and crimson the least healthy based totally on fantastic and poor standards, including whether the primary element was fruit, vegetable, whole grain, and so forth, and the quantity of saturated fats.

Researchers used employee ID numbers to music the purchases of five,695 employees buying food at MGH cafeterias. After establishing a three-month baseline length, the researchers tracked purchases made after the labels were delivered, and again after product-placement modifications made more healthy selections greater on hand. The interventions remained in the region at MGH cafeterias, and the study analyzed facts over two years after the visitors-mild labels had been first added.

The researchers discovered that the proportion of inexperienced-labeled ingredients bought increased while the proportion of the least healthful meals bought decreased.

The current study, a retrospective evaluation the usage of newly to be had object-stage calorie facts, associated the labeling with a reduction in calories over the two-year length studied and discovered that the largest calorie decreases were visible in crimson-classified food purchases. “So that suggests that not simplest were personnel’ consuming fewer calories at work,” stated lead author Anne N. Thorndike, MD, MPH, “however also that they had been enhancing the first-class of the energy they have been buying.”

For employees who visited the cafeterias maximum regularly, the anticipated reduction in calories equated to a weight reduction of up to 2 kg (four.4 kilos) over the years. However, Thorndike harassed, “this is not a diet.” Data display that human beings gain a mean of one to 2 pounds in keeping with 12 months. “If an application like this could assist assure that each adult maintained a constant weight as opposed to persevering with to gain,” she stated, “we should start to reverse the weight problems epidemic.”

Prior studies evaluating the impact of meals labeling interventions on calories bought has been either lab-primarily based or move-sectional, assessing an unmarried food or meal desire. “The distinction with our have a look at is that it checked out real-world purchases via personnel over numerous months,” said Thorndike.

A third of the nearly one hundred fifty million Americans who’re hired are obese, and the prevalence of weight problems is increasing throughout all industries, including healthcare. Obesity and weight-reduction plan-related sicknesses inclusive of diabetes and cardiovascular disease reportedly make contributions to better absenteeism and decrease productiveness as well as to approximately $200 billion in healthcare fees nationwide. Employees often acquire food at paintings, and a latest nationally consultant family survey determined that workplace food changed into high in energy from saturated fats and sugars, regularly which include gadgets which include pizza, regular soft drinks, cookies, and muffins. Practical techniques for reducing nonnutritive strength intake at some stage in the workday ought to assist cope with the rising incidence of obesity within the United States and global.

“More offices must be doing those form of interventions,” Thorndike said. “Wellness programs usually stop after a certain duration, but programs like this that human beings are exposed to every day once they visit work emerge as part of the place of job lifestyle. That’s the way you get people to make long-term modifications.”
