According to a study conducted in 19 workplace cafeterias, reducing potion size and replacing high-calorie foods and drinks with low-calorie options will encourage workers to buy foods and drinks with fewer calories. I did.
Researchers at the University of Cambridge, who led the study, say that even simple interventions like these can help address obesity levels.
An unhealthy diet, including eating more calories than necessary, plays a major role in increasing obesity. This increases the risk of diseases such as type 2 diabetes, heart disease, and many cancers, and increases the rate of premature death worldwide.
The environment in which we live and work is food And the drinks we consume. Especially poor areas in the region will exacerbate this effect. People living in less wealthy or less socio-economic status tend to have less access to healthy foods and higher obesity rates.
One of the key environments in which interventions can be carried out is in cafeterias such as schools, universities and workplaces. The workplace is the most common place to eat outside the home and typically accounts for 15% of the energy intake of working adults.
In the largest study of its kind, a team at the University of Cambridge tested the effect on calorie purchases when both portion size and availability of high-calorie food and drink were changed in 19 workplace cafeterias over a six-month period. Did. Their research results are today PLOS medicine..
The team has recruited a workplace cafeteria based in the distribution centers of major supermarket chains in the United Kingdom.
For 25 weeks, the team worked with catering companies to replace some high-calorie food and beverage products with low-calorie ones. For example, I replaced bacon and cheeseburgers with grilled chicken burgers. This reduced the average number of calories purchased per day by 4.8%.
Second, not only reduce the availability of high-calorie foods, Drink the product, The team has reduced the portion size of some high-calorie products by about 14%. For example, we offered some lasagna slices and chips, and reduced the number of some meatballs.
If both the availability and size of high-calorie food and drink were changed, this reduced the average number of calories purchased per day by 11.5% compared to baseline. For a typical worker, this would be about 50 kcal less meal per day.
Dr. James Reynolds, Behavior and Health Research Unit, University of Cambridge, lead author of the study, said: British adults burn 200-300 calories a day.. This study shows that reducing portion size and the availability of higher calorie options in the canteen may make a significant contribution to reducing excess calories in strategies to combat obesity.
“If workplace, school, and college cafeterias make these changes, this could help with a wide range of efforts to reduce calorie overconsumption and reduce population-level obesity.”
The workplace where the cafeteria was located was mainly located by people working in manual professions. On average, they are in poor health and have a high body mass index (BMI) compared to non-manual occupations.
Senior author Professor Dame Theresa Marteau, director of the Behavior and Health Research Unit, said: We need to find a fully functional intervention. Our study suggests that making relatively simple changes to workplace and other cafeteria menus may make a significant contribution to the approach to obesity in all groups. “
This survey was conducted over a longer period of time and used more sites than previous surveys. Persistent behavioral changes are known to be a major obstacle to lowering body mass index (BMI), but researchers did not find evidence during the study that the effectiveness of the intervention diminished over time.
In the cafeteria, the amount at the cash register has decreased slightly. 2.6% if only option availability is reduced, Portion size Also decreased. Researchers said this could have been a temporary effect, as the drops diminished over time, in part due to the fixed menus and product listings needed for the study. Suggests.
“Cafeteria should be able to compensate for the slight decline in revenue by changing the products it sells or by adding more strategies to make healthier food options more attractive,” Dr. Reynolds added. I did.
